Owner Narrative
The contact owns a 2021 Chevrolet Suburban. The contact stated that while in reverse (R), the vehicle failed to reverse as intended. The contactâs wife continued driving at approximately 55 MPH, and an unknown message was displayed, and the vehicle failed to exceed 55 MPH. Additionally, the transmission was stuck in gear and failed to upshift into the next gear as designed. The vehicle was pulled over to the side of the road, and the battery was disconnected and reconnected, but the message remained displayed. The vehicle was towed to an independent mechanic, where it was determined that the transmission control valve needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 81,600.
