Some 2021-2022 Volvo XC40 BEV vehicles may experience accelerator issues because of a corrupt acceleration signal caused by corrosion within the accelerator pedal sensor (APS).

Volvo became aware of the problem in the first quarter of 2022 when they started receiving customer reports of different issues with accelerator pedal behavior. The problem was presented to the Critical Concern Management Team (CCMT) and, following an investigation and risk assessment, a recall was initiated.

According to the defect report, water entering the APS wire harness could cause corrosion within the accelerator pedal’s internal circuits. If this happens signals from the pedal could become corrupt.
Depending on which signal corrupts, the faults may differ. Drivers may experience unintended acceleration or no acceleration, loss of drive power, and/or a no-start condition. These vehicles do have a built-in safety logic that will reduce the acceleration when a corrupt signal is received. The vehicle is still controllable, and the driver is always able to stop the vehicle using the brake pedal.

Vehicles produced between 9-08-2020 and 8-13-2021 had an older style harness. Since then, there was a change in the cable harness supplier. The last vehicle produced with the older style harness was produced on 8-13-2021.

Owners will be asked to return to their dealers to have the accelerator harness and sensors inspected for corrosion and repaired as necessary. A cable splice will be installed to prevent water intrusion and, as necessary, the connector terminal and APS could be replaced. Volvo’s number for this recall is R10170 and the NHTSA campaign number is 22V-288.
