What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The vehicle was driving in normal conditions, at approx 40mph in the evening. When accelerating to pass a car going slow in a 50mph+ road, the accelerator stuck in the cadillac. This forced a defensive decision to unfortunately hit the car in front versus unknown clearing.
As a result, the contact crashed into another vehicle and the air bags failed to deploy. The contact sustained a head, chest and foot injury that required medical attention. A police report was filed. The vehicle was destroyed. The manufacturer was not notified of the failure. The failure mileage was 20,000.
As I approached a street from a store parking lot, I stepped on the brake but the car did not slow. As I saw I was not going to stop, I tried to steer the car to the right to try to avoid crossing into traffic. The steering wheel would not turn.
Driver seat belt locked to reduce body movement resulting in bruises to left arm and chest. Air bags did not deploy. Extensive damage to front of vehicle colliding with vehicle ahead. Driver was transported to hospital. Injury consisted of soft tissue damage and trauma to neck.
The illumination of the warning light indicates the air bag system is not working.
A combination of the lower control arm alignment adjustment bolt, it is just a slot and standard bolt. The alignment becomes loose over time and begins to work side to side in the slot, so retightening the bolt is the only solution to keep it from moving.

The service brake assist, check engine, traction control, ABS, and stabili-trak warning lights were illuminated. The vehicle was towed to two independent mechanics; however, no failure was found. The dealer was made aware of the failure but confirmed that there was no recall associated with the VIN.
