What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
I started going up the driveway, I felt the car lurch foreward. I thought I was slamming on the brake, but hit the gas instead. The car crashed into the house moving the concrete block. The airbags did not deploy. I broke my neck at c4 and c5. I have seen 3 reports on this site detailing the same.
She slammed them harder and it slightly slowed down but she hit 2 guard rails and then crashed into the cinderblock wall destroying the front bumper, both front fenders, headlights and the internal aluminum bumper was crushed as it was designed to do. The air bags did not go off but she was not hurt.
Theair bags did not deploy. There were no injuries. The vehicle was towed to a tow yard and declared destroyed. The vehicle was not repaired. The approximate failure mileage was 60,000.
Tl* the contact owns a 2007 cadillac sts. The contact stated that the vehicle was started and the brakes were applied as she shifted into drive. The vehicle then abnormally accelerated and crashed into another vehicle parked in the driveway causing that vehicle to crash into the contacts home.
The air bags failed to deploy. A police report was filed. The front end was damaged and has been repaired. The manufacturer stated that they are unable to be of assistance. The vehicle failed to start on two occasions and was towed and repaired both times. The repair or replacement part was unknown.
Within the first month, the vehicle would not start after filling the gas tank the night before. Initially I thought perhaps it was a bad batch of gasoline. I filed a claim again my warranty, requested information from thomas petroleum who confirmed there was no issue with gasoline, warranty covered repair.
I went to the gas station to fill a gas. After I filled the car I saw big spot underneath of my car of gasoline. I went under the car I saw some gasoline color on the fuel tank. The dealer refused to fix it under the claimed recall.
Left headlight fills with water during a rainstorm or car wash. Headlamp is foggy with moisture reducing the light output and will cause a premature headlamp failure.
