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.

2004 Audi A4 Owner Comments

problem #1

Jan 022010

A4 1.8t

  • CVT transmission
  • 59,000 miles


At 59k miles, even though I had made every single scheduled maintenance at an official Audi dealership as recommended in the user manual, the engine still suffered premature timing belt failure at 59k miles which completely destroyed the engine. At this point I gave up and just got rid of the car. Since then i've owned a used Lincoln Navigator, Mercury Sable, Mazda Miata, and now a 2012 Hyundai Genesis Coupe, and none of those cars have had a single issue bad enough to warrant a trip to the dealership. This Audi on the other hand, had me at the dealership weekly for over a year. STAY AWAY
