2014 Chevrolet Malibu cruise control problems

Tl* the contact owns a 2014 chevrolet malibu. The contact stated that due to a faulty seal in the trunk, the vehicle flooded in february of 2014. The vehicle was repaired; however, the vehicle violently accelerated forward or in reverse. As a result, the contact rear ended another vehicle. The air bags failed to deploy. A police report was filed. The contact sustained a cervical neck strain that required medical attention. The vehicle was towed to a dealer, but was not repaired. The VIN was unknown.

This has happened twice now, once for my wife and the second time I was driving. Both incidents happened while in motion on the highway and the vehicle display showed reduced engine power and the vehicle de-rated and slowed automatically on the highway. The check engine light displayed and after connecting a code reader to the OBD and code p2138 was logged which is potentially a faulty throttle position sensor/ foot gas pedal.
