What 1991 Cadillac Seville owners say
Most recent owner complaints, unedited.
Lights shut off without warning @10pm on a small paved highway with very little traffic. My wife managed to come to a halt without incident while I reached over and pressed on the manual headlight switch, which came on. Had there been an accident whith some injuries or death there would have been alot of questions to be answered by someone. I am retired and I feel I should not have to pay for a defective computerized device. This was a program vehicle when I purchased it. I've been driving 50 years and never had the lights go out ever before.
Vehcile would involuntarily accelerate without warning. Mechanic unhooked cable to the idle speed monitor to keep from accelerating. Vehicle had started to cut off, battery indicator read low. Consumer got a jump, found out itwas fine & car was flooding.
There is a technical services bulletin 331708 issued on cadillacs 1998-1992, but the dealer I contacted said after 5 years they don't do anything. What should I do next?
While driving 35mph, vehicle would suddenly accelerate without warning. Has happened also while in parking lot & had foot on brakes at that time.
Accelerator pedal will go down to floor, causing the vehicle to take off to a higher speed.
Vehcle was hit in the front right side at 55mph by another vehicle and ran into a guardrail. Driver's side airbag did not deploy. Car was totaled. Dealer did not see.
Air conditioner: compressor failed twice. In addition, front brake pads were replaced twice.
Electrical system failed, resulting in loss of power.
Antilock brakes failed, causing accident.
