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.

problem #3

Mar 092005

A4 6-cyl

  • Automatic transmission
  • 109,000 miles


The vehicle developed a severe vibration in the front end. The upper, lower suspension arms and the tie rod ends were replaced. There was a severe oil leakage observed coming from the engine during acceleration. Oil was found in the spark plug cavities and the spark plug wires protective sleeve was brittle due to high engine temperature.

Multitude of probs. W/ almost every aspect (brakes, engine valves, oil light stays on, rain leaks, bad wheel bearings, etc.) of this car. Most frustrating has been rude and incompetent service by Audi dealer. After an expensive repair to the rear wheel bearings the dealer said that although not all the noise was gone, the car was safe enough to drive to calif.,(we live in NJ). We did not believe the dealer because a loud grinding noise remained and took it to another shop where both front control arms were found to be damaged. We were advised not to drive the car as it was not safe to do so.
