The accelerator pedal in the vehicles described above does not have a mechanical connection; instead, engine acceleration is controlled by an electronic throttle control. An accelerator pedal position sensor is part of the system, and it notifies the powertrain how much acceleration the driver wants.
A problem with the acceleration position sensor has been discovered in some 2016-2018 Chevrolet Malibu, 2017-2018 Buick LaCrosse, and 2018 Buick Regal vehicles, according to General Motors.
The above vehicles may have a condition that impairs the electrical connection to one of the vehicle’s position sensors in the accelerator pedal, according to the Special Coverage Adjustment report N182188250 Loss of Continuity inside Accelerator Pedal Position Sensor Circuit. The accelerator pedal will still work if the electrical connection is lost, but the car will enter a reduced engine power mode with reduced maximum acceleration and torque.
When this problem occurs, the malfunction indicator bulb and the check engine lights activate, and the diagnostic trouble code P2138 is set. The issue could result in a sudden and unexpected loss of power, putting everyone on the road in danger.
G.M. will provide special coverage for the above-mentioned condition for a period of ten years or 150,000 miles (240,000 km), whichever comes first, from the day the vehicle was first put into service, regardless of ownership.
