Ignition Switch problems of the 2000 Cadillac Seville

On two separate occasions my old 2000 gm Cadillac sts stalled while driving on the highway. This was not a mechanical problem - it was some sort of defect. Note that it was "repaired" in between the incidents, do it was not the same initial problem. I filed a complaint back then, but got no response. The mechanics at the palo alto Cadillac dealer seemed to know of the problem. At the time, they said it was a failure of some sensors on the flywheel. I don't know if this was related to the current ignition switch problem. Having a vehicle stall at 65 mile per hour is absolutely terrifying. You lose power steering and brakes. It would have certainly ended up in an accident if I didn't understand how cars work. I was able to shift into neutral and restart the car. My point is, there was a defect on this car that appeared to be known by gm, and was also ignored. The complaint was ignored by the NHTSA. I think you should also inquire with gm what was known about this defect. As I wrote - they seemed to have known that this was a problem, and just repaired it, rather than understand the risk they were making us take. I ended up selling the car because of this issue.
