What owners report

Airbags did not deploy in a massive front end collision. That failure caused me physical injury which possibly would not have occurred had the airbags deployed. I donât know how many 2008 Cadillac CTS are on the road at this time but feel it is an important enough matter that should be investÃgated.

After backing the vehicle in to a parking spot I wanted to straighten it out. When I put the car in drive there was a loud shrilling noise (sounded somewhat like brakes peeling) and the car accelerated forward with my foot on the brake.
On the morning of december 27, 2011 the stability trac system light came on indicating that it had failed. The car did not react properly and the steering wheel was uncontrollable leading to an accident. The car did a 360 and hit a guard rail.
There were no warning messages on the dashboard. There is no damage to the outside of the car. I had put my claim through my insurance company, and they deemed it mechanical failure.
I have several receipts from the vehicle being serviced because of the faulty windshield washer heater system that was supposed to be disabled caused an electrical short in the vehicle because it was not properly sealed water got in the wires and caused the computer to be fried this happened before the car still only…
