Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was driving on the highway and the car suddenly lost power without warning, due to fuel pump failure. I have seen a lot of complains about this defect. I think Audi should take responsibility for this safety issue. The Audi should recall the car to prevent this from happening to other Audi owners, because it is very dangerous to loss power on the highway without any warning.”
NHTSA complaint #10427000, filed 2011-09, 89,000 miles“The car was maintained well, as per manufacturers specs. Both the fuel pump and power steering pump failed at 4 yrs/approx 60,000 miles which is unacceptable by today's quality standards dealer investigated an existing fuel pump recall on the model but my VIN was out of range . I believe the recall (06v017) incorrectly excluded some candidate vins.”
NHTSA complaint #10255826, filed 2009-01, 61,000 miles“Fuel pump failure on 2004 Audi A4. Audi had a recall of 2003 model A4 and a6 vehicles for premature fuel pump failures. I experienced a similar problem with my 2004 Audi A4. While I caught this issue before a complete failure, this premature failure could result in significant safety issues.”
NHTSA complaint #10267693, filed 2009-05, 49,426 miles“Audi 2004 A4. Driving on the highway, fuel pump fails. Battery light lit up right before fuel pump completely failed. I took the car to the dealer and they replaced the fuel pump the very next day. There is a recall currently on the fuel pump for the 2003 A4 1.8t. Is there a possibility that the failure in my fuel pump is the same and that the recall should also cover 2004?”
NHTSA complaint #10200877, filed 2007-08, 61,500 miles“Audi A4 3.0 while driving to the airport to pick up friends the car suddenly died. Only 68000 miles. Had to wait for a tow to a dealership. I was in another state. Friends had to rent a car and pick me up. Turned out to be a bad fuel pump and had to be replaced. Approximately two months earlier I had a bad fuel filter that had to be replaced. Only use 93 octane. Not good. Disappointed in what seems to be a regular occurrence.”
