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.

Was driving on freeway for a few hours during which car was running fine, and car suddenly lost power just after I got off freeway and approached a mountain road incline. There was no warning light, or prior symptoms to engine failure, it just stopped. With help, I was able to get car out of the middle of the road and to safety. Tried to troubleshoot, used engine error code reader, and no fault codes found. Performed basics checked for potential fuel vapor lock due to altitude; checked oil, coolant and fuel levels- and all levels were ok. Battery was functioning - as radio, lights worked. Car has been consistently serviced and maintenance was current. Car was towed to nearest dealer, diagnosis by dealer fuel pump failure due to clogged fuel filter. My issue is that Audi does not indicate service maintenance for fuel filter. There is not any maintenance recommendations or guidance in either the owner's manual or published list of recommended services to replace or check filer. There also were not any warning lights, fault codes or indications to watch for. I feel that it is negligent of the manufacturer to not indicate any service interval to change fuel filter in order to prevent fuel pump failure, and to ensure the safe operating conditions of the vehicle. The car lost power on a winding mountain road and put me at danger without warning. I am curious if this fuel pump incident could be associated with known fuel pump issues, NHTSA #PE08027. Key side notes, while I am the second registered owner, this car was purchased by my father who was the original owner, but for insurance and registration purposes the vehicle was transferred over to me, but I have all original records of the vehicle and can verify all maintenance services have been performed.

I was driving my 2004 Audi A4 (1.8, convertible) on a local road at approx 30mph, when the accelerator suddenly dropped from under my foot and the car accelerated very rapidly. It felt like the cruise control had come on by itself (the cruise control was completely off at the time). I put the car in neutral and pulled over. When I shut the car off, the gas pedal popped up and felt normal. When I turned the car back on several times, it continued to immediately accelerate all the way with the gas pedal dropping to the floor. The car is now being towed to a mechanic. Had I been in a tighter situation at the time, it could've been ugly.

I'm 26, mother of a 9 yr & 14 mo old. Currently, I'm unemployed and I can't afford to pay $2,500 to repair the fuel pump that Audi initially installed in my car. I was so excited to buy this Audi used 4 yrs ago with 80,000 miles. This has been the most costly and the most unsafe vehicle I have owned...stalling out was not fun and very scary. Audi dealerships have been trained well to deny owning up to the car's defects. Is Audi waiting for an accident to happen and people/children die" I guess the cost of paying for the court cost when someone dies is not a big worry for the company - probably cost more to have the cars recalled & safely repaired than to pay for court & funeral cost. I'm sure Audi has been aware of this problem since 2003 and refuse to own up to their 2003 mistake flowing over to the 2004 models. It makes no sense that Audi won't "step up to the plate" and have a recall. Maybe the Audi company really can't repair the car and the problem will always exist? I would hope they have smart engineers that could fix the problem. Audi really is coming across as having poor customer concerns for our safety. What a shame, I can barely make ends meet and now, I can't even afford to take my car out of the shop...but, maybe it's a blessing - at least, my children and I are safe by not driving that car. Come on Audi - recall now before some dies!!! and, what is the vehicle safety folks doing for us??? I just an angry mother hoping someone will listen & with the belief that the NHTSA can help...I wish I had never bought this car, I'm still making monthly payments for the car that I'm scared to drive now. I'm wondering by venting on this site, if Audi even gets this information" this is a "no kidding" matter that should be taken seriously and fixed as soon as possible by the responsible company to show that they really care for their customers!

Fuel pump noisy and not working. Cant bear the noise as its too loud inside and outside. Replaced fuel filter still not use. Browsed through internet and saw its happening to all 2004 A4 models and no recalls from the manufacturer as its common in all A4 2004 models. Request to file an complaint on this issue and request manufacturer to recall fuel pump in all A4 2004 models.
