2000 cadillac dts deville touring sedan. Diamond white with toupe. Within six months of ownership my car was in the dealer more than me driving. Half the valves were replaced on a new car. I filed under the lemon law. Was told on my 24,000 mile car that under indiana law I could get a replacement. No one informed me about a runaway problem or a defective motor. My car on the expressway took off on its own as if someone had turned the cruise control on. I only know what it felt like. I remember checking the gas pedal with my foot and could tell it was down as if stuck lower in a depressed position. I tried to move it back up and it came but fell back as if stuck there. I then panicked as I was in chicagoland express and found a long off ramp to go off the expressway. As my car kept going I stood on the brake with two hundred pounds and could feel the anti lock brake take over. I also down shifted the system is speed blocked and would only go into second. The car went on a curve before leaving the highway off ramp. It hit an embankment, tore off the oil pan and trans cover, and flattened all tiers as it went up and over two lanes and a median before resting in the northbound lane direction when I exited south. My byback from the better business bureau came two days later informing me that the engine in their opinion was defective. No one bothered to tell me how bad that car was from a mechanical prospective until I almost died. They ordered gm to buy it back. However my brand new car was totaled by the insurance for under body damage. There wasn't a dent on the metal above. The insurance took the buyback order from the bbb. I never heard a word about it after that.

2002 cadillac deville - throttle stuck full open - traveling at highway speeds in cruise. Touched the brake to allow for traffic. Then touched "resume" on the cruise control; throttle opened fully and stuck there. The only way to stop was to turn off the ignition, which I did. Then had no power steering or power brakes, while still in traffic.

My 2000 cadillac deville will occasionally accelerate of its own accord. It can happen when on cruise control or when not. The only way to get it to stop accelerating is to put it in neutral and tap the accelerator with your foot. It is quite disturbing and takes some seconds to realize what to do. Fortunately has not happened in close quarters yet, but the stories about the old man who mistakenly put his foot on teh accelerator rather than the brake are bogus. His car did it. This happened also in oct. 2006. The dealer crest cadillac claimed to never heard of such a thing. They cleaned teh throttle body and only happened a couple times after that and was not a problem until this week. It again happened on the expressway and I was up to 85 MPH before I regained control.

There seems to be a wiring problem with my vehicle I believe the manufacturer is aware and is ignoring the problem, I have heard of vehicle fires on this particular model (cadillac deville 2004) the fuses seem inadequate and blow frequently on equipment such as cruise control daytime running light and cigarette lighter.
