NHTSA complaint #10234215, filed 2008-07, 3,500 miles“On many occasions, my 2007 Cadillac STS experienced the exact same ignition problem as other more popular models of the 2007 Cadillac. This problem causes the engine to suddenly quit while driving causing serious danger to being hit by the car behind me. It does not matter whether you are driving at 20 MPH or 65 MPH. It randomly causes the engine to die. An ignition recall has been issued on many (or all) models of the 2007 Cadillac except this STS model. The dealer, thompson Cadillac, confirmed that it is the ignition problem. However, GM refuses to pay for repair. Can you assist me?”
NHTSA complaint #10626179, filed 2014-08, 72,000 miles“I have a 2007 Cadillac STS - top of the line car. At 800 miles, I had to have a new engine put in the car and now at 4,000 miles, the electrical systems fail, with out any warning. The car's electrical system totally shuts down, the hydraulic sytems fails and the engine is obviously off. There was no indication of any failure or any warning, the car's electrical system simply shuts off - completely. Emergency flashers do not work, there is no access to the trunk for safety material. …”
NHTSA complaint #10212704, filed 2007-12, 4,100 miles“Engine randomly stops running while car is going at high speeds or low speeds. Engine will restart and travel for various distances before occurring again. This problem has been reported on many 2007 Cadillac and GM has made a recall on all 2007 Cadillac except the STS model ! It uses the same ignition switch as the other models. Very dangerous situation if another car is behind.”
