The car while turning intermittently dies and looses any acceleration stalls and most of the time starts back up when lifting foot of the gas and sometimes dies. Also the car accelerates on its own sometimes very quickly. The car stalling while making a left turn got me t-boned by someone while making a left hand turn. I'm not the only one with this problem. This defect is going to get somebody killed.

Most recent owner complaints, unedited.
This problem is intermittent. On warm days, when driving with airconditioning.turned on, the car stalls and then quickly starts up again. No notice from computer problem light. Note other owners of this car have had similar problems even after dealer check.........one dealer informed me that it is the baffle around the fuel take that cuts the ignition out and I should keep fuel completely filled to top or at least half full. Yesterday when the problem happened again, it was warm in los angels, had 11 gallons in tank and still had problem. No recall was ever initiated by us government or gm. My car is a 1990 cad with only 80,000 miles and maintained regularly.
Car accelerated out of control with speed at 100+ miles per hour. The brakes failed/ would not move. The accelerator moved away from my foot. This happen a total of 4 times with my car. Each time the dealer said it was a different problem. My car was a 1990 cadillac sedan deville, 4 door. The toyota recall described exactly what happen to my car. The 911 call televised on the news with the family that was killed in the toyota car, the caller said "the car was accelerating out of control and the brakes had failed". This is what I remember with my incidents and this brought back those memories. I hope this can help. I do not believe it is the floor mats, that is what I thought. The dealership said it was the brake booster at first and then said it was the throttle body. I did sent a complaint to gmc in detroit, mi but never heard back.
