Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2002 Audi A4 Owner Comments

problem #4

Dec 012010

A4 6-cyl

  • 56,600 miles


The contact owns a 2002 Audi A4. The contact stated that while driving 30 mph, the vehicle suddenly accelerated which caused the vehicle to go through an intersection. The contact engaged the brakes to stop and shut the vehicle off. The contact restarted the vehicle and the rpms increased rapidly so the contact had the vehicle towed to an authorized dealer. This failure was the second occurrence. The dealer performed a diagnostic test but could not find the cause for the failure. The dealer suggested that the floor mat had become caught on the accelerator pedal but the contact stated that it had not happened. The failure mileage was 56,600. Updated 01/18/11 updated 01/31/11

While traveling 15-20 mph vehicle suddenly accelerated. Consumer lost control of vehicle, and hit a small tree to bring vehicle to a stop. Vehicle was looked at by dealer/mechanic, but they were not able to duplicate the problem, and determined there was nothing wrong with it. Consumer was afraid that this vehicle might do the same thing again, and did not want to drive this vehicle.

Multiple cases of uncontrolled acceleration in 2002 Audi A4. 2 cases last year I had to put the car in neutral and turn off the ignition. All the others have been momentary lasting less than a second. All cases were after I accelerated, the pedal would not come back. The car has been in numerous times for this problem to the dealer who can never find anything wrong. They have documented the problem though. My last time in I discussed the possibility of using the lemon law. I finally had an accident last Friday evening pulling off from a light when the people in front of me suddenly braked and my car kept going.

Unexplained accelleration for 1/2 mile serious safety while no one was injured or physically harmed, they could have been seriously injured. In fact my wife who was driving the car was able to avoid a loaded school bus before she was able to find a spot to pull off the road and disable the vehicle. Car was towed to Audi dealer. Dealer unable to determine what caused accelleration. Actually the representative implied that it was impossible for this to happen without a computer code. This is a brand new vehicle approximately 1 week old. Primary driver is joan ashman who is afraid to drive this vehicle again. Since service has not found anything there is nothing else they can do. Deal management has not addressed the issue with us. I have called an left a message for general manager to call. I have contacted Audi custer relations and filled a report. They have indicated that it may take some time to investiget to resolve our saftey concern with this particular vehicle.
