What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
I put the car in reverse and released the parking brake. The car started to move backwards. However, the back passenger door was wide open, and the passenger was standing outside the car in the path of the open door. The door hit a guide wire running from the top of a power pole to the sidewalk beside the car.
This all happened within a few seconds and there were no warning lights or messages before or during the accident. I was not injured and there were no other people present. The police were called and inspected the damages. The insurance company was contacted due to damages. No one was in the parking lot at the time.
However, when brake pressure was increased to its peak at -0.5s, deceleration effectively stalled. Electronic Anomaly: The Traction Control System (TCS) was reported as "Active" throughout the braking event, indicating potential improper electronic intervention.
I am submitting this follow-up to document new information and continuing concerns regarding my 2024 Cadillac Lyriq EV, which experienced sudden unintended acceleration during a parking maneuver.
On September 9, 2025, while slowly turning into a parking space at approximately 7 mph, the vehicle suddenly experienced unintended acceleration. There were no warnings, alerts, or Safety Alert Seat vibrations prior to the surge.
I then applied the brakes gently and the brakes did not work. I then pushed the brakes hard and still no brakes worked. I tried pumping the brakes and nothing worked. The car gently ran into the car in front of me causing no damage to the car in front and he kept on his way.
There was no injury, police report, airbag deployment, or fire. The vehicle was taken to the local dealer. After twelve days, the vehicle was not diagnosed or repaired. The manufacturer was contacted, who confirmed the vehicle had functioned as designed. The failure mileage was 8,600.
The contact stated no warning light was illuminated. The contact stated that failure reoccurred when she was parking the vehicle in a parking lot. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the ABS system had failed and caused a loss of braking ability.
