Volvo Malaysia has issued a recall for 545 vehicles in the country over a potential issue with brake control module software, automotive website PaulTan.org reports. The move is apparently part of a larger recall by the automaker, which involves over 100,000 of its cars sold across several markets across the world.
The list of vehicles recalled consists of Volvo cars released under the 2023 model year, which includes the XC40, XC60, XC90, C40, S60, V60, and S90. It is said that customers with affected cars may experience a stiff pedal and the loss of electronic braking functions. Should the issue occur, drivers might be alerted with a warning message, a lit up malfunction lamp in the gauge cluster, or a stiff brake pedal.
According to AutoBlog, the problem is caused by a fault in the Brake Control Module 2, which is triggered by the in-vehicle diagnostic test that checks the grounding of the system. The issue itself is reported to not occur often, but if it were to trigger, it would result in the vehicle reverting to its hydraulic system in order to slow down to a complete stop. This forces the driver to handle braking manually without the assistance from the car’s brake-by-wire system, as well as software-defined safety systems such as Anti-lock Brake System (ABS), Electronic Stability Control (ESC), Traction Control, Pilot Assist, Adaptive Cruise Control and one-pedal driving.
Thankfully, Volvo said there have been no reports of accidents or personal injuries resulting from this issue so far, and clarified that the recall was being taken as a precautionary measure. That being said, owners of the affected models will be notified directly by Volvo to send their vehicles to its service centres in order to have the issue rectified.
Additionally, a software update for the Brake Control Module 2 is in the works and is planned to be distributed via an over-the-air (OTA) update. The new code is expected to be implemented on 20 February 2023, while Volvo car owners will be notified on 15 March.
