2002 Cadillac DeVille Owner Comments

problem #6

Apr 162014


  • 91,000 miles


The car started accelerating, on its own, up to 40 mph from a stop sign or red light. The gas pedal was not stuck. Legacy Ford in lagrande, Oregon has told us it is an internal problem and they will have to put their diagnostic machine on it. We have already paid them $179.36 for labor, gasket and cleaner. They had told us to bring the car to them if it happened when we were in town so they could test it further. Last week I was in town and it happened so I took it to them. They couldn't diagnose the problem at the time so that is why they need to use the diagnostic machine. I tried to report this to Cadillac but they weren't interested in my problem.

2002 Cadillac Deville, driving in cruise control at highway speeds. I touched the brake to slow for traffic. When I put the cruise control in "resume" the throttle stuck completely open. I was not able to control the car, other than (eventually) turn off the ignition.

DeVille 8-cyl

  • Automatic transmission
  • 32,000 miles
A 2002 Cadillac Deville dhs 4-door sedan was originally parked head-first into a parking space. When the driver started the ignition, stepped on the brake and then put the vehicle into the reverse gear "R", slowly and partially releasing the brake, the vehicle moved back normally as expected. After about 15 feet, the driver turned the steering wheel to the right to maneuver the vehicle into position to leave the parking lot. At that moment, the engine unexpectedly revved up, the brakes failed, the vehicle accelerated in the reverse direction, the steering mechanism failed (driver's actions on the steering wheel had no impacts on the actual motions of the front wheels), and a significant "clanking" noise (as if some major components in and around the engine compartment area had been broken) was clearly noticeable. The vehicle came to a stop after scratching the side of another parked 4-door sedan and subsequently hitting a sign post about 35 feet from its original position. The vehicle could be seen with its engine compartment lowered and the fenders "rested" on and touching the front wheels, as if the front axle had broken. Loose bearings / nuts could be found in the vicinity of the vehicle. The vehicle became inoperable.
