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-AMG W177 A-Class
2019 Mercedes-AMG W177 A-Class: radar sensor control unit failure
In August 2019, recall campaign RC2707 was issued for Mercedes-AMG 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-AMG W177 A-Class: plate beneath spare wheel recess could crack
In September 2019, recall campaign RC2712 was issued for Mercedes-AMG 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-AMG W177 A-Class: airbag may detach from base plate
In October 2019, recall campaign RC2727 was issued for Mercedes-AMG 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-AMG W177 A-Class Hatch: sunroof may not have bonded
In January 2020, recall campaign RC2747 was issued for Mercedes-AMG 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-AMG W177 A-Class: condensation leak and electrical malfunctions
In August 2020, recall campaign RC2804 was issued for Mercedes-AMG 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-AMG W177 A-Class Hatch: too much oil in DCT
In December 2020, recall campaign RC2838 was issued for Mercedes-AMG 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.
