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.

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?

2007 Cadillac Sts bought as a demo in Florida in April, with about 3,500 miles on it: I told the salesman that this was going to be used exclusively at my Connecticut address and I would be driving it there shortly after purchase. My complaints are first with the conditions of sale in Florida, and subsequently, with the failure to repair issues both in Florida and now Connecticut. I bought the vehicle with the agreement that it would be made 'as new as possible.' This was to include a new battery (since it was dead in the showroom), the oil would be changed, and all the door and dash scuffs would be removed. The battery has finally been replaced here after failing twice, the scuffs they fixed in Florida keep coming right back on the doors and dash, and I just paid for the oil change that never took place for the sale. The day I drove the car off, the salesman indicated they 'topped it off.' It was into service at least three times within the first weeks of ownership in Florida. It has already been in for service three days here in Connecticut, my last visit to service was for two days, and nothing was done or solved. The voice command system just doesn't work properly. It continues to hear me incorrectly, or hears/repeats me correctly but then does not do what it says. As you use the wheel button to progress through the six presets and go back to the first, it skips over the first and sometimes the second button. To make matters worse, the volume periodically takes off with increasing loudness uncontrollably. In any case, they tell me that corporate is aware of the voice problems and has been trying to come up with a software fix. To my thinking, this is an '07 and they haven't come up with a fix for it yet? if it hasn't been fixed yet, it is not going to happen late in '08 and they claim I am not alone with these issues!

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. Therefore, if this occurs on a highway at a reasonable speed, there clearly will be an accident - potential fatal accident by a car simply shutting down, with no indication of same.
