Review: Mercedes-Benz C117.I CLA 45 AMG (2013-16)

Overview

Released in Australia in October 2013, the Mercedes-Benz C117 Series I (C117.I) CLA 45 AMG was a compact sedan. Manufactured in Kecskemet, Hungary, the all-wheel drive Mercedes-Benz CLA 45 AMG was powered by a 2.0-litre turbocharged petrol engine that was mated to a seven-speed double clutch transmission.

M133 engine

Shared with the W176 A 45 AMG , the four-cylinder M113 engine was hand-produced by MDC Power GmbH in Kölleda, Germany. The M133 engine had a gravity-die sandcast all-aluminium crankcase with ventilation bores, an aluminium cylinder head, a forged steel crankshaft, forged pistons with friction-optimised piston rings, NANOSLIDE coating for the cylinder walls, ‘spectacle honed’ cylinder liners (i.e. surface treatment applied when already bolted in place), spray-guided direct injection via piezo injectors (operating between 100 bar and 200 bar), a twin-scroll turbocharger which provided maximum boost pressure of 1.8 bar (26.1 psi), air-to-water intercooling, double overhead camshafts, continuously variable camshaft adjustment, four valves per cylinder and a compression ratio of 8.6:1. Furthermore, maximum engine speed was 6700 rpm.

Compliant with EU6 emissions standards, the M133 engine could perform up to five injections per combustion cycle in the cold-start and warm-up phases to reduce emissions. Furthermore, the M133 engine had an ECO start/stop function which enabled it to shut down when the vehicle was stationary in traffic to minimise fuel consumption.

Upon its release, the CLA 45 AMG could accelerate from rest to 100 km/h in 4.6 seconds and had an electronically-limited top speed of 250 km/h. Over the combined ADR 81/02 test cycle, fuel consumption for the CLA 45 AMG was 7.0 litres per 100 km.

From September 2015 production, the M113 engine produced 280 kW and 475 Nm. According to Mercedes, the increase in power for the M133 engine was due to a ‘newly configured valve assembly’, reconfigured timing and turbocharging; maximum charge pressure, however, remained at 1.8 bar. To reduce fuel consumption, a newly introduced ‘sailing’ function could decouple the engine from the powertrain when the driver released the accelerator at speeds from 60 km/h to 160 km/h. As a result of these changes, the post-September 2015 CLA 45 AMG could accelerate from rest to 100 km/h in 4.2 seconds.

AMG Speedshift DCT transmission

The AMG Speedshift DCT (double clutch transmission) was directly flange-mounted on the transversely installed engine and offered three driving programmes:

• Controlled Efficiency (‘C’): enabled the ECO start/stop function and provided softer throttle response, smooth gearshifts and earlier upshifts for fuel efficient driving;
• Sport (‘S’): disabled ECO start/stop, provided greater throttle response, higher engine speeds before upshifting and faster gearshifts. Under full loads, ignition and injection could be briefly interrupted during upshifts for faster gearshifts and a ‘particularly throaty sound’; and,
• Manual (‘M’): for manual gearshifts via the steering wheel paddles.

In all modes, the DCT had a double declutching function during downshifting, though its characteristics varied according to the selected mode. Furthermore, in C and S modes, a ‘Momentary M’ mode enabled the driver to activate manual mode (‘M’) – without having to remove a hand from the steering wheel – by pressing the ‘up’ of ‘down’ shift paddle once. The transmission would subsequently revert to the previously selected mode based on the current driving situation and driving style.

From September 2015 production, shorter ratios were introduced for the third through seventh forward gears and new ‘Dynamic Select’ transmission modes were introduced:

• Comfort: for ‘comfort-oriented driving’ with a ‘subdued’ engine note and gentle gearshifts. In Comfort mode, the newly introduced ‘sailing’ function could decouple the engine from the powertrain when the driver released the accelerator at vehicle speeds between 60 km/h and 160 km/h. The ECO start/stop function was also active in Comfort mode;
• Sport: provided greater throttle response, more aggressive gearshifts and a more ‘throaty’ engine sound. Furthermore, the sailing and ECO start/stop functions were disabled;
  Sport+: provided faster gearshifts and a modified shift strategy which included double de-clutching. Furthermore, Sport+ enabled partial cylinder suppression – via a momentary and defined retardation of ignition and injection under full throttle – for rapid gearshifts;
• Individual: enabled the driver to vary individual parameters for the engine, transmission and three-stage electronic stability control; and,
• Race: provided ‘even more immediate’ response for the engine and throttle than Sport+, and was configured to maintain an optimum engine speed in the lowest possible gear when driving at racetrack speeds.

Haldex all-wheel drive system

The Mercedes CLA 45 AMG’s Haldex all-wheel drive system utilised an electrohydraulically controlled multi-disc clutch which was integrated with the rear axle differential. In normal driving, torque was directly entirely to the front wheels for optimum efficiency. If slip was detected at the front wheels, however, a hydraulic pump would instantaneously press the clutch discs together to direct up to 50 per cent of the engine’s torque to the rear axle (i.e. a 50:50 front:rear torque split). The all-wheel drive system provided a variable torque distribution, with the front:rear determined by vehicle speed, lateral and longitudinal acceleration, steering angle, speed difference between the individual wheels, selected gear and accelerator position.

Dimensions

Compared to the W176 A 45 AMG hatchback with which it shared its underpinnings, the C117 CLA 45 AMG was 332 mm longer (at 4691 mm), 3 mm narrower (1777 mm) and 1 mm lower (1416 mm), though wheelbase length was unchanged (2699 mm); furthermore, kerb weight was 30 kg greater at 1585 kg. Boot capacity for the CLA 45 AMG was 470 litres.

Suspension

The CLA 45 AMG had three-link front suspension with MacPherson struts and four-link rear suspension which consisted of three control arms and one trailing arm per wheel; both front and rear suspension included coil springs, gas-pressure shock absorbers and anti-roll bars. Compared to the C117 CLA-Class , changes for the CLA 45 AMG included:

• Stiffer springs and dampers;
• Additional negative camber front and rear;
• Thicker stabiliser bars;
• For the front suspension, more rigid bearings in the lower link plane;
• Stiffer steering knuckles;
• Modified rear strut bearings; and,
• More rigid rear axle bearings.

From September 2015 production, the CLA 45 AMG was equipped with ‘AMG Ride Control’ which consisted electronically-controlled dampers that could be varied at each wheel according to the driving situation and road conditions. The driver could also pre-select the basic damping characteristics in two stages.

Steering

The C117 CLA 45 AMG had an electromechanical power steering (EPS) system with a steering ratio of 14.5:1. Furthermore, the EPS system also had the following functions:

• Counter-steering in the event of over-steer;
• Corrective steering when braking on road surfaces with different levels of grip (split-friction braking);
• Mitigating the extent to which front-wheel drive influences the steering;
• Compensating cross winds and road gradients; and,
• Active Parking Assist, which used sensors on the front bumper to measure parking spaces and provided automated steering for the parking manoeuvre.

Safety equipment

Standard safety equipment for the C117 CLA 45 AMG included dual front airbags, a driver’s knee airbag, front and rear side airbags, full-length curtain airbags, ABS, electronic brake force distribution, brake assist, electronic stability control, traction control, front seatbelts with pre-tensioners and force limiters, an ‘active bonnet’, and Mercedes-Benz’s automatic emergency call system.

Further safety technologies – fitted as standard – for the CLA 45 AMG included:

• Mercedes-Benz’s ‘Pre-Safe’ system: activated by emergency braking, panic braking, pronounced over- or under-steering, critical steering movements or heavy support by the adaptive Brake Assist system. In response, Pre-Safe would prepare for a collision by deploying the seatbelt tensioners, close the side windows and sliding sunroof (where fitted) and adjust of the front passenger seat to an ideal position for maximum effectiveness of the restrain systems;
• Collision Prevention Assist (radar-based collision warning with adaptive Brake Assist): Collision Prevention Assist operated at speeds between 7 km/h and 250 km/h, and could detect stationary objects when driving at speeds of up to 70 km/h. Collision Prevention Assist monitored the distance to the vehicle ahead, would provide visual and audible warning to the driver if there was a collision risk and would optimise braking power (adaptive Brake Assist) for when the driver depressed the brake pedal. At initial speeds of less than 20 km/h, Collision Prevention Assist could prevent rear-end collisions;
• Distronic Plus (adaptive cruise control with brake warning): an ‘adaptive’ cruise control system which used two short-range radar sensors positioned behind the front bumper to monitor the road up to 30 metres ahead, and a long-range radar located behind the radiator grille which had a range of 200 metres. Operating at speeds up to 200 km/h, Distronic Plus used an electronic control unit to analyse the information from both radar systems to calculate the engine, automatic transmission and braking parameters required for proximity control. As such, Distronic Plus could automatically apply the brakes to prevent the vehicle from becoming too close to traffic ahead (the time interval could be specified) and accelerate back to the set speed when traffic allowed. To accelerate from rest, the driver only needed to operate the Distronic stalk on the steering column or briefly depress the accelerator pedal. With Distronic Plus, automatic deceleration of up to four (4) m/s²was possible. If Distronic Plus detected that heavier braking was required, a warning light would illuminate in the instrument cluster and be accompanied by an audible warning. Furthermore, the electronic proximity control system could be activated independently of Distronic Plus at speeds over 30 km/h to alert the driver if they were approaching another vehicle too rapidly;
• Attention Assist: operated at speeds in excess of 80 km/h and monitored driver behaviour and steering movements for signs of drowsiness; if detected, the driver would be provided with visual and audible warnings;
• Blind spot assist (passive): used two radar sensors in the rear of the vehicle to warn the driver before an indicated lane-change if a vehicle is in the driver’s blind spot; and,
• Lane keeping assist (passive): used a camera behind the windscreen to monitor lane markings and detect if the vehicle was drifting outside its lane. If so, acoustic and visual warnings would be issued.

Stability control system

The electronic stability control system (Mercedes-Benz’s Electronic Stability Program, or ESP) had an ‘ESP Sport Handling’ mode which raised thresholds for intervention; the electronic stability control could also be switched off if desired. When ‘ESP Sport Handling’ mode was engaged, the driver could select the ‘Race Start’ function for optimum acceleration from rest.

The stability control system also included an ‘ESP Curve Dynamic Assist’ function that provided slight braking applications to the inside wheel when cornering to produce a yaw moment around the vertical axis to increase turn-in.

Brakes

The Mercedes CLA 45 AMG had 350 mm by 32 mm front brake discs with four-piston callipers and 330 mm by 22 mm rear discs with single-piston callipers; both front and rear discs were ventilated and perforated.

Euro NCAP testing

In Euro NCAP testing , the Mercedes-Benz C117 CLA 200 received a five star safety rating which included a 91 per cent adult occupant protection rating and a 75 per cent child occupant protection rating. In the offset crash test, occupant protection was generally assessed as good although chest protection was rated as adequate. Maximum points were awarded in the side impact test though, in the more severe pole test, chest protection was rated as marginal.

Under ANCAP’s methodology , this testing resulted in a five star adult occupant protection rating with a score of 36.16 out of 37.

Features: Mercedes CLA 45 AMG

Standard features for the Mercedes CLA 45 AMG included 19-inch AMG multi-spoke alloy wheels with 235/35 R19 tyres, a Harman Kardon Logic7 surround sound system with twelve speakers, a single-disc CD/DVD player, digital radio tuner (DAB+), MP3/WMA/AAC compatibility, auxiliary inputs (3.5 mm/USB/iPod), Bluetooth mobile phone connectivity and audio streaming, COMAND APS with a 17.8 cm display, HDD navigation, 10 GB music register, internet access and voice recognition (‘Linguatronic’), dual-zone climate control air conditioning (‘Thermotronic’), AMG seats in black ‘Red Cut’ leather, power adjustable and heated front seats, cruise control, bi-xenon headlights with integrated daytime LED running lights, front and rear parking sensors, a reversing camera with dynamic guidelines, automatic headlights, rain-sensing wipers, an AMG steering wheel with nappa leather and Alcantara trim, 40:60 split and folding rear seats, remote central locking, power adjustable mirrors with heating and folding functions, kerb view tilting of the passenger door mirror on reversing, power windows, a power-operated panoramic sunroof, automatically dimming rear-view and door mirrors, front seat memory settings, ambient lighting, tinted windows, rear privacy glass, AMG instrument cluster with ‘Racetimer’, a trip computer, an alarm and immobiliser.

AMG Performance exhaust

For Australia, the CLA 45 AMG was fitted with an AMG Performance exhaust system which included a switchable exhaust flap that varied the exhaust note. Compared to the standard twin-pipe exhaust system, the AMG Performance exhaust provided a ‘more emotive, fuller engine sound when driving under full load and when changing gears’.

Review: Mercedes-AMG C117.II CLA 45 (2016-19)

Overview

Commencing production in June 2016, the Mercedes-AMG C117 Series II (C117.II) CLA 45 could be identified by the new A-wing design of its front apron which will include splitter inserts in matt titanium grey and high-gloss black flics. Other changes include a new bootlip spoiler and rear diffuser insert with four vertical fins.

Safety equipment

Compared to the C117.I CLA 45, standard safety equipment for the C117.II CLA 45 was extended to include ‘Active Brake Assist’. Operating at speeds up to 250 km/h to monitor the traffic ahead and at speeds up to 50 km/h for stationary objects, Active Brake Assist would issue a visual warning (when driving at speeds over 7 km/h) and an optical warning (when driving at speeds over 30 km/h if there was a collision risk. At speeds below 105 km/h (250 km/h in conjunction with Distronic Plus), Active Brake Assist would initially provide partial autonomous braking to reduce vehicle speed and alert the driver. Furthermore, adaptive Brake Assist would calculate the braking force required and prime the braking system for optimum response when the driver depressed the brake pedal. If the driver did not respond and a collision was unavoidable, then maximum braking force would be applied to reduce vehicle speed. At initial vehicle speeds of up to 40 km/h, rear-end collisions could be prevented.

Features

For the Mercedes C117.II CLA 45, standard features were extended to include Mercedes’ ‘COMAND Online’ infotai Nment system with a 20.3 centimetre TFT display (previously COMAND APS with a 17.8 cm display), Apple CarPlay and Android Auto smartphone integration, a Garmin MAP Pilot navigation system (previously Becker), and LED headlights with integrated LED daytime running lights.

Overview

Manufacturers, or importers, issue recalls for defects or faults which have the potential to cause injury. Generally, manufacturers will inform the original buyers if their vehicle is subject to a recall and of the steps required to remedy the defect or fault. Please note that the recalls below (if any) are for Australian-delivered vehicles only. Furthermore, the number of recalls should not be taken as an indication of a model’s reliability or its safety more generally.

Recalls: Mercedes-Benz C117 CLA-Class

2014 Mercedes-Benz C117 CLA Diesel: oil leak

In January 2015, a recall was issued for Mercedes-Benz vehicles with the OM651 turbo-diesel engine that were available for sale during 2014. In these vehicles, the seal ring between the timing chain tensioner and the engine may leak oil – this could result in a hazard for other road users and, in extreme cases, a fire risk (PRA 2015/14509).

2015-16 Mercedes-Benz C117 CLA: loss of drive (fractured dual clutch)

In July 2016, a recall was issued for Mercedes-Benz C117 CLA-Class vehicles that had double clutch transmissions. In these vehicles, a welded seam in the transmission’s dual clutch assembly could fracture and cause a loss of drive – this could pose an accident hazard to the vehicle’s occupants and other road users. The recalled Mercedes-Benz C117 CLA-Class vehicles were available for sale from 1 November 2015 to 30 January 2016 (PRA 2016/15529).

2016 Mercedes-Benz C117 CLA: left window airbag may not deploy

In June 2017, a recall was issued for Mercedes-Benz C117 CLA vehicles that were available for sale in Australia from 1 October 2016 to 5 November 2016. In these vehicles, the left window airbag may not have been manufactured to specifications and may not deploy in the event of a collision, thereby increasing the risk of injury to vehicle occupants (PRA 2017/16114).

2016 Mercedes-Benz C117 CLA: front passenger airbag may not deploy as intended

In July 2017, a recall was issued for Mercedes-Benz C117 CLA vehicles that were available for sale from 1 October 2016 to 1 December 2016. In these vehicles, the propellant mixing ratio in the igniters of the front passenger airbag assembly may not meet specification. In the event of deployment, the front passenger airbag may therefore not deploy as designed, thereby increasing the risk of injury for the front passenger. For the recalled vehicles, the front passenger airbag assembly was to be replaced. For the VINs of the recalled vehicles, please seePRA 2017/16195.

2015-17 Mercedes-Benz C117 CLA: starting current limiter could overheat

In October 2017, a recall was issued for Mercedes-Benz C117 CLA vehicles that were available for sale in Australia from 31 January 2015 to 31 January 2017. If the starter were to become blocked due to prior damage and if multiple and/or extended start attempts were made, then the starting current limiter could be electrically overloaded and overheat. At worst, this could cause nearby components to ignite and cause a fire. For the VINs of the recalled vehicles, please see PRA 2017/16367.

2017 Mercedes-Benz C117 CLA White Art Edition: centre rear anchorage point missing

In August 2018, recall campaign RC2534 was issued for Mercedes-Benz C117 CLA White Art Edition vehicles that were available for sale in Australia from 3 July 2017 to 28 November 2017. In these vehicles, the top tether anchorage point for the centre rear bench seat may have been omitted, such that a child restraint could not be attached. For the VINs of the recalled vehicles, please see PRA 2018/16975.

2018 Mercedes-Benz C117 CLA-Class: front passenger airbag may not deactivate

In January 2019, recall campaign RC2594 was issued for 2018 model year Mercedes-Benz C117 CLA-Class vehicles that were available for sale in Australia from 1 March 2018 to 2 May 2018. In these vehicles, the automatic occupant detection function for the front passenger seat may not comply with specifications. If a rearward-facing child seat was installed in the passenger seat, the front passenger airbag may not be deactivated as intended and could therefore be deployed in the event of a collision – this increased the risk of injury for the child. For the VINs of the recalled vehicles, please see PRA 2019/17304.

2016-18 Mercedes-Benz C117 CLA-Class: front passenger seat detection

In August 2020, recall campaign RC2749 was issued for Mercedes-Benz C117 CLA-Class vehicles that were available for sale in Australia from 1 April 2016 to 28 February 2018. In the front passenger seat, an installed child seat may be identified as a person, or a lightweight person may be identified as a child seat. If the front passenger seat occupant was misidentified, then:

1. The front passenger airbag may not deploy as intended, despite the presence of a person in the front passenger seat;
2. The front passenger airbag may deploy, despite a child seat being installed.

In the event of a collision, there was an increased risk of injury or death to the person sitting in that seat in the event of a collision. For the VINs of the recalled vehicles, please see PRA 2020/18462.

2017 Mercedes-Benz C117 CLA-Class: faulty universal joint in the steering shaft

In July 2021, recall campaign RC2894 was issued for 2017 Mercedes-Benz C117 CLA-Class vehicles. A component in the universal joint of the steering shaft was not manufactured to specifications and this, over time, may impair the driver’s ability to steer the vehicle. If the steering did not perform as expected, there was an increased risk of a collision and therefore injury to vehicle occupants and other road users. For the VINs of the recalled vehicles, please see REC-001672.

2015-19 Mercedes-Benz C117 CLA with sunroof: panel between sunroof and windscreen may detach

In September 2021, recall campaign RC2885 was issued for 2015-19 Mercedes-Benz C117 CLA-Class vehicles with panoramic sunroofs. During a prior service repair, the panel between the windshield and the panoramic sunroof may not have been correctly bonded. The bonding may therefore deteriorate over time, such that the panel could partially or fully detach from the vehicle; this condition increased the risk of injury to vehicle occupants and other road users. For the VINs of the recalled vehicles, please see REC-004951.

Mercedes-Benz C117 CLA: ‘Power Steering Malfunction, Service Required’

In June 2014, Mercedes-Benz USA issued Service Bulletin LI46.35-P-059241 for Mercedes-Benz C117 CLA-Class vehicles with VINs preceding WD#117####N083207. After the engine was started, the instrument cluster may display the warning message ‘Power Steering Malfunction, Service Required’, an acoustic warning would sound and the steering would feel sluggish. Furthermore,

• No faults would be logged in the steering control unit; and,
• Fault code C063100 would be logged in the ESP control unit and fault code U013187 would be logged in the instrument cluster control unit.

According to the service bulletin, these symptoms could be due to:

• Faulty contact of power supply to the electric steering system; or,
• A component fault in the control unit of the electric steering system.

Initially, the power supply to the electric steering was to be checked. If the problem was still present, then the control unit/motor unit for the electric steering was to be replaced.

Mercedes-Benz C117 CLA 250 4MATIC: rear differential noise

In March 2015, Mercedes-Benz USA issued Service Bulletin LI35.40-P-060213 for Mercedes-Benz C117 CLA 250 4MATIC vehicles. Due to a fault with the internal differential assembly, a thumping, grinding or chatter noise may be heard from the rear differential when turning. To test, the electrical connector for the all-wheel drive solenoid valve was to be disconnected and the vehicle taken for a test drive; if the noise was gone, this verified the condition and the rear differential was to be replaced.

Recalls: Mercedes-Benz C118 CLA-Class

2019 Mercedes-Benz C118 CLA-Class: airbag may detach from base plate

In October 2019, recall campaign RC2727 was issued for Mercedes-Benz C118 CLA-Class vehicles that were available for sale in Australia from 1 April 2019 to 30 September 2019. In these vehicles, the four lock nuts for fastening the airbag may have been installed incorrectly. The airbag may therefore detach from the base plate and enter the vehicle interior at high speed. In the event of a collision, this increased the risk of injury to vehicle occupants. For the VINs of the recalled vehicles, please see PRA 2019/17890.

2019-20 Mercedes-Benz C118 CLA-Class with M282 engine (1.3-litre turbo): oil leak

In October 2020, recall campaign RC2819 was issued for Mercedes-Benz C118 CLA-Class vehicles that had 1.3-litre M282 turbocharged petrol engines and were available for sale in Australia from 1 December 2019 to 31 March 2020. In these vehicles, engine oil may escape from the turbocharger oil feed line, leaking onto the underfloor panelling and the road. If the engine oil came into contact with hot components in the engine compartment, it could cause a fire. Furthermore, oil leaking onto the road would increase the risk of a collision for other road users. Both of these consequences could increase the risk of a collision and injury for vehicle occupants and other road users. For the VINs of the recalled vehicles, please see PRA 2020/18612.

Mercedes-Benz X118 CLA-Class: eCall software

In November 2020, recall campaign RC2826/RC2826A was issued for Mercedes-Benz C118 CLA-Class vehicles that were available for sale in Australia from 3 April 2019 to 1 September 2020. In these vehicles, the software of the communication module for the emergency call system (‘eCall’) may have been incorrectly programmed. In the event of an emergency, it would not be possible for vehicle occupants to contact emergency services, either manually or automatically. To fix, the software was to be updated ‘over the air’ (OTA), such that there was no need to visit a dealership; owners would automatically receive a software update unless they objected to it. If owners did object, they would need to visit a dealership for a manual update instead. For the VINs of the recalled vehicles, please see PRA 2020/18593.

2019 Mercedes-Benz C118 A-Class: unsecure crash sensor may delay airbag deployment

In August 2021, recall campaign RC2919 was issued for 2019 Mercedes-Benz C118 A-Class vehicles. The side crash sensors – which were used to determine when to deploy the airbags in the event of a collision – may not be secured correctly to the body of these vehicles. If the sensors were not properly secured, there may be a delay in triggering the airbag and this increased the risk of injury to vehicle occupants. For the VINs of the recalled vehicles, please see REC-001691.

2019-20 Mercedes-Benz C118 CLA-Class: eCall system may not contact emergency services

In December 2021, recall campaign RC2932-RC2933 was issued for 2019-20 Mercedes-Benz C118 CLA-Class vehicles. Due to a software issue, the automatic network search of the emergency call system (eCall) communication module may be deactivated. If this occurred, the automatic and manual emergency call function may not be available outside of the network coverage of certain providers. If the eCall system was deactivated, it would not be possible for vehicle occupants to contact emergency services in the event of an emergency (either manually or automatically). As a consequence, emergency vehicles may not be directed to the affected vehicle or may be delayed and this could increase the risk of death if a serious injury had occurred. For this recall, no action was required by consumers since the software would be updated ‘over the air’ (i.e. without requiring a workshop visit). For the VINs of the recalled vehicles, please see REC-004979.

2019-20 Mercedes-Benz C118 CLA-Class: emergency call may not contact emergency services

In April 2022, recall campaign RC2957 was issued for 2019-20 Mercedes-Benz C118 CLA-Class vehicles. Due to a software issue, the automatic network search of the emergency call system (‘eCall’) communication module may be deactivated. If the eCall system was deactivated, it would not be possible for the vehicle occupants to connect with emergency services, either manually or automatically, in the event of an emergency. As a result, emergency vehicles may not be directed to the affected vehicle or may be delayed; this could increase the risk or severity of injury. For the VINs of the recalled vehicles, please see REC-005401.

2020 Mercedes-Benz C118 CLA-Class: fuel feed hose leak

In September 2022, recall campaign RC3065 was issued for 2020 Mercedes-Benz C118 CLA-Class vehicles. Due to a manufacturing defect, the fuel feed hose could chafe and cause a fuel leak in the engine compartment – this could result in a vehicle fire that posed a risk to vehicle occupants, other road users and bystanders. For the VINs of the recalled vehicles, please see REC-005513.

Mercedes-Benz X118 CLA-Class Shooting Brake: eCall software

In November 2020, recall campaign RC2826/RC2826A was issued for Mercedes-AMG C118 CLA-Class vehicles that were available for sale in Australia from 3 April 2019 to 1 September 2020. In these vehicles, the software of the communication module for the emergency call system (‘eCall’) may have been incorrectly programmed. In the event of an emergency, it would not be possible for vehicle occupants to contact emergency services, either manually or automatically. To fix, the software was to be updated ‘over the air’ (OTA), such that there was no need to visit a dealership; owners would automatically receive a software update unless they objected to it. If owners did object, they would need to visit a dealership for a manual update instead. For the VINs of the recalled vehicles, please see PRA 2020/18593.

2020 Mercedes-AMG C118 CLA 45 S: spark plug failure

In June 2021, recall campaign RC2882 was issued for Mercedes-AMG C118 CLA 45 S vehicles that were available for sale in Australia from 3 February 2020 to 24 April 2020. The spark plugs in these vehicles may not meet specification and may therefore fail during regular use. If the spark plugs failed and parts entered the combustion chamber, this could lead to engine damage. Furthermore, an engine stall could occur; this would increase the risk of a collision and injury or death to vehicle occupants and other road users. For the VINs of the recalled vehicles, please see PRA 2021/19004.

2019 Mercedes-AMG C118 A-Class: unsecure crash sensor may delay airbag deployment

In August 2021, recall campaign RC2919 was issued for 2019 Mercedes-AMG C118 A-Class vehicles. The side crash sensors – which were used to determine when to deploy the airbags in the event of a collision – may not be secured correctly to the body of these vehicles. If the sensors were not properly secured, there may be a delay in triggering the airbag and this increased the risk of injury to vehicle occupants. For the VINs of the recalled vehicles, please see REC-001691.

2019-20 Mercedes-AMG C118 CLA-Class: eCall system may not contact emergency services

In December 2021, recall campaign RC2932-RC2933 was issued for 2019-20 Mercedes-AMG C118 CLA-Class vehicles. Due to a software issue, the automatic network search of the emergency call system (eCall) communication module may be deactivated. If this occurred, the automatic and manual emergency call function may not be available outside of the network coverage of certain providers. If the eCall system was deactivated, it would not be possible for vehicle occupants to contact emergency services in the event of an emergency (either manually or automatically). As a consequence, emergency vehicles may not be directed to the affected vehicle or may be delayed and this could increase the risk of death if a serious injury had occurred. For this recall, no action was required by consumers since the software would be updated ‘over the air’ (i.e. without requiring a workshop visit). For the VINs of the recalled vehicles, please see REC-004979.

2019-20 Mercedes-AMG C118 CLA-Class: emergency call may not contact emergency services

In April 2022, recall campaign RC2957 was issued for 2019-20 Mercedes-AMG C118 CLA-Class vehicles. Due to a software issue, the automatic network search of the emergency call system (‘eCall’) communication module may be deactivated. If the eCall system was deactivated, it would not be possible for the vehicle occupants to connect with emergency services, either manually or automatically, in the event of an emergency. As a result, emergency vehicles may not be directed to the affected vehicle or may be delayed; this could increase the risk or severity of injury. For the VINs of the recalled vehicles, please see REC-005401.

2020 Mercedes-AMG C118 CLA-Class: fuel feed hose leak

In September 2022, recall campaign RC3065 was issued for 2020 Mercedes-AMG C118 CLA-Class vehicles. Due to a manufacturing defect, the fuel feed hose could chafe and cause a fuel leak in the engine compartment – this could result in a vehicle fire that posed a risk to vehicle occupants, other road users and bystanders. For the VINs of the recalled vehicles, please see REC-005513.

2022 Mercedes-AMG C118 CLA 45: tyres may not meet specifications

In May 2023, recall campaign RC3135 was issued for 2022 Mercedes-AMG C118 CLA 45 vehicles. For these vehicles, the tyres may not meet manufacturing specifications and the tyre could deflate. If the tyre lost air pressure suddenly, the driver may lose control of the vehicle and this increased the risk of injury to vehicle occupants and other road users. For the VINs of the recalled vehicles, please see REC-005683.

Recalls: Mercedes C117 CLA 45 AMG

2015-16 Mercedes-Benz C117 CLA 45 AMG DCT: loss of drive

In July 2016, a recall was issued for Mercedes-AMG C117 CLA 45 vehicles that had double clutch transmissions. In these vehicles, a welded seam in the transmission’s dual clutch assembly could fracture and cause a loss of drive – this could pose an accident hazard to the vehicle’s occupants and other road users. The recalled Mercedes-AMG C117 CLA 45 vehicles were available for sale from 1 November 2015 to 30 January 2016 (PRA 2016/15529).

2016 Mercedes-AMG C117 CLA 45: left window airbag may not deploy

In June 2017, a recall was issued for Mercedes-AMG C117 CLA 45 vehicles that were available for sale in Australia from 1 October 2016 to 5 November 2016. In these vehicles, the left window airbag may not have been manufactured to specifications and may not deploy in the event of a collision, thereby increasing the risk of injury to vehicle occupants (PRA 2017/16114).

2016 Mercedes-AMG C117 CLA 45: front passenger airbag may not deploy as intended

In July 2017, a recall was issued for Mercedes-AMG C117 CLA 45 vehicles that were available for sale from 1 October 2016 to 1 December 2016. In these vehicles, the propellant mixing ratio in the igniters of the front passenger airbag assembly may not meet specification. In the event of deployment, the front passenger airbag may therefore not deploy as designed, thereby increasing the risk of injury for the front passenger. For the recalled vehicles, the front passenger airbag assembly was to be replaced. For the VINs of the recalled vehicles, please seePRA 2017/16195.

2015-17 Mercedes-AMG C117 CLA 45: starting current limiter could overheat

In October 2017, a recall was issued for Mercedes-AMG C117 CLA 45 vehicles that were available for sale in Australia from 31 January 2015 to 31 January 2017. If the starter were to become blocked due to prior damage and if multiple and/or extended start attempts were made, then the starting current limiter could be electrically overloaded and overheat. At worst, this could cause nearby components to ignite and cause a fire. For the VINs of the recalled vehicles, please see PRA 2017/16367.

2013-17 Mercedes-AMG C117 CLA 45: deployment of driver’s airbag

In February 2018, recall RC2437/A was issued for Mercedes-AMG C117 CLA 45 vehicles that were available for sale in Australia prior to September 2017. If the steering column was not sufficiently grounded and the steering column switch was damaged or faulty, an electrostatic discharge could cause the driver’s airbag to deploy. If these conditions occurred, an airbag warning message in the instrument cluster display and a red airbag indicator lamp (signalling that the steering column module was damaged/faulty) would alert the driver. If the airbag deployed in the absence of a collision, it could injure and distract the driver. For the VINs of the recalled vehicles, please see PRA 2018/16572.

2018 model year Mercedes-AMG C117 CLA 45: front passenger airbag may not deactivate

In January 2019, recall campaign RC2594 was issued for 2018 model year Mercedes-AMG C117 CLA 45 vehicles that were available for sale in Australia from 1 March 2018 to 2 May 2018. In these vehicles, the automatic occupant detection function for the front passenger seat may not comply with specifications. If a rearward-facing child seat was installed in the passenger seat, the front passenger airbag may not be deactivated as intended and could therefore be deployed in the event of a collision – this increased the risk of injury for the child. For the VINs of the recalled vehicles, please see PRA 2019/17304.

2016-18 Mercedes-AMG C117 CLA 45: front passenger seat detection

In August 2020, recall campaign RC2749 was issued for Mercedes-AMG C117 CLA 45 vehicles that were available for sale in Australia from 1 April 2016 to 28 February 2018. In the front passenger seat, an installed child seat may be identified as a person, or a lightweight person may be identified as a child seat. If the front passenger seat occupant was misidentified, then:

1. The front passenger airbag may not deploy as intended, despite the presence of a person in the front passenger seat;
2. The front passenger airbag may deploy, despite a child seat being installed.

In the event of a collision, there was an increased risk of injury or death to the person sitting in that seat in the event of a collision. For the VINs of the recalled vehicles, please see PRA 2020/18462.

2017 Mercedes-AMG C117 CLA: faulty universal joint in the steering shaft

In July 2021, recall campaign RC2894 was issued for 2017 Mercedes-AMG C117 CLA vehicles. A component in the universal joint of the steering shaft was not manufactured to specifications and this, over time, may impair the driver’s ability to steer the vehicle. If the steering did not perform as expected, there was an increased risk of a collision and therefore injury to vehicle occupants and other road users. For the VINs of the recalled vehicles, please see REC-001672.

2015-19 Mercedes-AMG C117 CLA with sunroof: panel between sunroof and windscreen may detach

In September 2021, recall campaign RC2885 was issued for 2015-19 Mercedes-AMG C117 CLA-Class vehicles with panoramic sunroofs. During a prior service repair, the panel between the windshield and the panoramic sunroof may not have been correctly bonded. The bonding may therefore deteriorate over time, such that the panel could partially or fully detach from the vehicle; this condition increased the risk of injury to vehicle occupants and other road users. For the VINs of the recalled vehicles, please see REC-004951.

Mercedes C117 CLA 45 AMG: turbocharger failure due to oil feed line contamination

In January 2015, Mercedes-Benz USA initiated Service Campaign 2014120001 for 2014-15 model year Mercedes-Benz C117 CLA 45 AMG vehicles. In these vehicles, the turbocharger may need to be replaced due to contamination of the oil feed line.

To determine if the turbocharger was to be replaced, axial play in the turbocharger would be measured by pushing the end shaft up to the end stop – by hand – in the direction of the compressor by exerting pressure on the turbine wheel shaft (exhaust side). If axial play exceeded 0.08 mm, this indicated premature wear of the turbo shaft bearings such that the turbocharger and oil feed lines were to be replaced. According to the Service Campaign, the estimated replacement rate was 25 per cent.

Released in Australia in July 2019, the Mercedes-Benz C118 CLA-Class was a compact sedan which had a coupe-like profile. Manufactured in Kecskemet, Hungary, the Mercedes-Benz C118 CLA-Class range for Australia initially consisted of the CLA 200, with the CLA 250 4MATIC following in October 2019… Read full Mercedes-Benz C118 CLA-Class review
