Recalls: Mercedes-Benz W177 A-Class
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 W177 A-Class
2018 Mercedes-Benz W177 A 200: high beam headlights may remain on
In October 2018, recall campaign RC2568 was issued for Mercedes-Benz W177 A 200 vehicles that were available for sale in Australia from 1 July 2018 to 31 August 2018. When the Adaptive High Beam Assist function was used, the high beam headlights may remain permanently activated, or may not automatically dim. Since the high beam headlights may dazzle other road users, this increased the risk of a collision. Owners of affected Mercedes-Benz W177 A 200 vehicles were to contact their local dealership for a software update. For the VINs of the recalled vehicles, please see PRA 2018/17082.
2018-19 Mercedes-Benz W177 A-Class: engine may shutdown or not restart
In March 2019, recall campaign RC2647 was issued for Mercedes-Benz W177 A-Class vehicles that were available for sale from 22 May 2018 to 4 February 2019. Software in the powertrain control unit may not operate as intended and the engine warning light may not activate to warn the driver of the fault. As a result, the engine control unit may reset such that –
- The engine may not restart if the reset occurred during an ‘ECO’ stop; and,
- The engine may lose power and cause the vehicle to coast if the reset occurred while the vehicle was being driven.
Unexpected engine failure therefore posed a hazard to vehicle occupants and other road users. For the VINs of the recalled vehicles, please see PRA 2019/17430.
Mercedes-Benz W177 A-Class: high beam headlights may stay on
In April 2019, recall campaign RC2646 was issued for Mercedes-Benz W177 A-Class vehicles that were available for sale in Australia from 1 February 2019 to 28 March 2019. In these vehicles, the high beam headlights may not deactivate by using the high beam lever unless manually activated by the driver. However, the high beam headlights could be deactivated by turning the rotary light switch to the manual driving light setting. If the high beam headlights remained on, the occupants of oncoming vehicles may have their vision impaired and this increased the risk of a collision. For the VINs of the recalled vehicles, please see PRA 2019/17444.
2019 Mercedes-Benz W177 A-Class: radar sensor control unit failure
In August 2019, recall campaign RC2707 was issued for Mercedes-Benz W177 A-Class vehicles that were available for sale in Australia from 1 March 2019 to 30 July 2019. Due to an error in the active brake assist software, one of the radar sensor control units may fail. If the radar sensor control unit failed, the ‘Active Brake Assist’ function may not activate and this increased the risk of a collision and injury to both vehicle occupants and other road users. To fix, the software for the radar sensor control unit was to be updated. For the VINs of the recalled vehicles, please see PRA 2019/17768.
2018-19 Mercedes-Benz W177 A-Class: plate beneath spare wheel recess could crack
In September 2019, recall campaign RC2712 was issued for Mercedes-Benz W177 A-Class vehicles that were available for sale in Australia from 1 June 2018 to 27 February 2019. In these vehicles, the protective tin plate beneath the spare wheel recess could crack in its outer areas. If the tin plate experienced multiple cracks in the same area, it could detach from the vehicle – this increased the risk of injury to other road users. For the VINs of the recalled vehicles, please see PRA 2019/17814.
2019 Mercedes-Benz W177 A-Class: airbag may detach from base plate
In October 2019, recall campaign RC2727 was issued for Mercedes-Benz W177 A-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 Mercedes-Benz W177 A-Class Hatch: sunroof may not have bonded
In January 2020, recall campaign RC2747 was issued for Mercedes-Benz W177 A-Class Hatch vehicles that were available for sale in Australia from 1 January 2019 to 28 February 2019. In these vehicles, the glass pane of the panoramic sliding sunroof may not have been correctly bonded. If the glass pane protruded from the vehicle, wind noises may be heard. If unnoticed, the glass pane may – over time – fully detach from the vehicle and this would increase the risk of a collision and/or injury for other road users. For the VINs of the recalled vehicles, please see PRA 2020/18133.
2018-19 Mercedes-Benz W177 A-Class: condensation leak and electrical malfunctions
In August 2020, recall campaign RC2804 was issued for Mercedes-Benz W177 A-Class Hatches that were available for sale in Australia from 1 September 2018 to 30 April 2019. In these vehicles, the condensation drain hose of the air conditioning system may not have been correctly installed. Condensation could therefore leak into the vehicle interior and cause electrical malfunctions. Specifically, the following may occur:
- The airbag control unit may fail;
- It may not be possible to start the vehicle;
- Engine ‘limp home’ mode may be activated during vehicle operation;
- The fuel pump may not work correctly; and,
- The emergency call system may be impaired.
These events increased the risk of a collision that may cause injury or death to vehicle occupants and other road users. For the VINs of the recalled vehicles, please see PRA 2020/18490.
2019-20 Mercedes-Benz W177 A-Class Hatch with M282 engine (1.3-litre turbo): oil leak
In October 2020, recall campaign RC2819 was issued for Mercedes-Benz W177 A-Class Hatch 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.
2019-20 Mercedes-Benz W177 A-Class Hatch: too much oil in DCT
In December 2020, recall campaign RC2838 was issued for Mercedes-Benz W177 A-Class Hatch vehicles that were available for sale in Australia from 2 April 2019 to 30 March 2020. In these vehicles, the volume of oil in the dual clutch transmission (DCT) may be too high – this could cause the transmission oil to foam up, such that the vehicle may stall. In extreme driving situations, transmission oil may leak onto the road, increasing the risk of a collision, or come into contact with hot engine components and create a fire risk. The maximum levels of carbon dioxide and exhaust gas emissions may also be exceeded. For the VINs of the recalled vehicles, please see PRA 2020/18737.
2020 Mercedes-Benz W177 A-Class Hatch: missing seatbelt bracket
In April 2021, recall campaign RC2858 was issued for Mercedes-Benz W177 A-Class Hatch vehicles that were available for sale in Australia from 1 September 2020 to 26 November 2020. These vehicles may be missing the right rear seat’s belt bracket, which was used for fastening the child seat to the ISOFIX holder. In these circumstances, the child seat could not be securely fastened and attached to the correct specification. If the child seat was not securely fastened, the child may not be adequately restrained in their seat; these circumstances increased the risk of injury in the event of a collision. For the VINs of the recalled vehicles, please see PRA 2021/18928.
2019 Mercedes-Benz W177 A-Class: unsecure crash sensor may delay airbag deployment
In August 2021, recall campaign RC2919 was issued for 2019 Mercedes-Benz W177 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.
2020-21 Mercedes-Benz W177 A 250e Hatch: battery housing seal and moisture ingress
In December 2021, recall campaign RC2970 was issued for 2020-21 Mercedes-Benz W177 A250e Hatchbacks. Over time, the sealing of the high-voltage battery housing may reduce and allow moisture to enter. That moisture could cause the battery to corrode, in turn resulting in an electrical short circuit and potential fire. For the VINs of the recalled vehicles, please see REC-005028.
2018-20 Mercedes-Benz W177 A-Class: eCall system may not contact emergency services
In December 2021, recall campaign RC2932-RC2933 was issued for 2018-20 Mercedes-Benz W177 A-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 W177 A-Class Hatch: emergency call may not contact emergency services
In April 2022, recall campaign RC2957 was issued for 2018-20 Mercedes-Benz W177 A-Class Hatch 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.
2020-21 Mercedes-Benz W177 A-Class Hatch: brake caliper bolts may come loose
In May 2022, recall campaign RC3008 was issued for 2020-21 Mercedes-Benz W177 A-Class Hatch vehicles. Due to a manufacturing error, the brake caliper bolts may not have been tightened sufficiently and could become loose. If this occurred, it may reduce braking performance, thereby increasing the risk of a collision and injury to vehicle occupants and other road users. For the VINs of the recalled vehicles, please see REC-005428.
2019 Mercedes-Benz W177 A-Class Hatch: incorrect volume of transmission oil
In June 2022, recall campaign RC3040 was issued for 2019 Mercedes-Benz W177 A-Class Hatch vehicles. Due to a manufacturing issue, the volume of transmission oil in these vehicles may be too high or too low. This could cause the vehicle to stall and, if the oil level was too high, oil could leak and cause a fire. These hazards increased the risk of a collision and injury to both vehicle occupants and other road users. For the VINs of the recalled vehicles, please see REC-005465.
2020 Mercedes-Benz W177 A-Class Hatch: fuel feed hose leak
In September 2022, recall campaign RC3065 was issued for 2020 Mercedes-Benz W177 A-Class Hatchbacks. 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-Benz W177 A-Class: tyres may deflate or tread detach
In July 2023, recall campaign RC3160 was issued for 2022 Mercedes-Benz W177 A-Class vehicles. For these vehicles, the tyres may not meet manufacturing specifications. As a result, the tyres may deflate and/or the tyre tread could detach (partially or completely) whilst driving. Either of these conditions could result in a loss of vehicle control, thereby increasing the risk of a collision and injury to vehicle occupants and other road users. For the VINs of the recalled vehicles, please see REC-005739.
