Volvo XC40 BEV Acceleration Problems

Posted on by

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.

The automobiles listed above do not have a mechanical connection for the accelerator pedal, instead, there is an electronic throttle control responsible for engine acceleration. The system includes an accelerator pedal position sensor, which tells the power train how much acceleration the driver requests.

General Motors have identified a problem affecting the acceleration position sensor in some 2016-2018 Chevrolet Malibu, 2017-2018 Buick LaCrosse and 2018 Buick Regal vehicles.

According to the Special Coverage Adjustment report N182188250 Loss of Continuity within Accelerator Pedal Position Sensor Circuit, the above vehicles may have a condition that affects the electrical connection to one of the vehicle’s position sensors in the accelerator pedal. If the electrical connection is interrupted, the accelerator pedal will still function, but the vehicle will enter a reduced engine power mode in which the maximum acceleration and torque are reduced.

When this problem occurs the driver will notice a reduction in engine power, the malfunction indicator lamp and the check engine lights illuminate and a diagnostic trouble code P2138 will be set. The problem could result in an unexpected and instant loss of power, which puts everyone on the road in danger.

General Motors will be offering special coverage for the condition described above for a period of 10 years or 150,000 miles (240,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership. 2016-2018 model year Chevrolet Malibu, 2017-2018 model year Buick LaCrosse and 2018 model year Buick Regal vehicles.

2014-2015 Kia Soul Acceleration Defect

Posted on by

Kia will be notifying owners of certain 2014-2015 Kia Soul and Soul Electric vehicles about a safety defect that could result in difficult acceleration. Due to bending of an unsupported section of the accelerator pedal, the pedal could fracture if excessive force is applied. Field experience and testing indicates that such force has only occurred when stationary, but if drivers continue to operate their vehicle with this problem, it may increase the risk of an accident.
