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.
