My 1996 Cadillac Deville concourse has developed a defect whereas it will accelerate on it's own, shutting down the A/C for more horsepower while it does it. I have seen it accelerate through 80 MPH once. The condition goes away temporaily when the engine is shut off and recranked, returning at unpredictable intervals. My local Cadillac dealer refused to repair the problem, giving me a "go away and never come back speech" advising me strongly to junk the car (it's in almost perfect condition otherwise). I think I May have a 'smoking gun' car for those people who have killed, maimed, destroyed property with cars that accelerate by themselves. The dealer had the car overnight and claimed to have made no frepairs, but it has not repeated this since I got it back today. It was a chronic conditioin three days ago near the end of a 3000 mile trip. …
Very dangerous situation occurred while driving on city roads where posted speeds are 35-45 MPH. The car just started to speed up on its own and I could not get the engine to slow down. The only way I could avoid a traffic accident was to ride the brakes continuously. By the time I got home the brakes were smoking and extremely overheated. I almost could not stop with the engine racing and the brakes worn out. I had to shut the engine down while still in drive, almost running into the wall of my house. I am 70 years old and was very scared. On edmunds .com there are three other reported instances of the same thing happening with the same make and model. My car is undriveable and I will have to get it towed from my house to the dealer for it to be checked out, please follow up on this as it is a very dangerous condition. I was very close to having an accident.

One day I could smell gas fairly strong, and then I stopped at a friends shop, opened the hood and you could see gas spurting out. As I was looking up this part and then spoke with someone that informed me that yes there had been a recall on the fuel rail and that it was closed. Of course I had to park it to keep it from catching on fire.. It's a 1996 Cadillac Deville and it's in mint condition. I am asking for some help in getting this repaired/replaced.
