Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“We own an Audi A4 that we have had too many repairs. The car has needed a turbo at 55,000 miles, oil pump at 63,000 miles, ignition computer at 68,000 miles and rack and pinion steering at 73,000 miles. We are aware that the car is at high mileage, but this car is suppose to get 200,000 miles out of it. The car was serviced at dealers the entire time. We think that perhaps there are defects in the car that other drivers are experiencing.”

NHTSA complaint #10005491, filed 2003-02, 73,000 miles

“My brake light started beeping and flashing one day while driving. The beeping and flashing continued through the next couple of weeks. I took my car to my mechanic and he said I would have to take it to the dealer because Audi won't release their service codes. I called the dealer and asked what was going on. The mechanic asked me were you driving your car in the rain? I had quite a few sarcastic responses to the stupid question but I just said, yeah. I assume a car is engineered to be driven in all climates including, rain. A product should be designed to perform its intended use. …”

“The car is experiencing unintended acceleration, usually, but not always, after heavy acceleration. Over 10 occurrences. Cannot remedy by pulling back the accelerator. Car must be turned off and the engine must record 0 RPM to remedy the problem.”

“Bosch ABS control unit has failed causing a flashing ABS indicator and a solid brake light. Cause is electronic. Many documented cases found on line. Abs will not engage. Audi will not recall, but vw has recalled for the same problem.”

“I own a 1999 Audi A4 and the lcd in the gauge cluster has faulted and no longer works. It provides important information to the driver and works about 80% when its extremely cold. Once the car warms up all the information is not able to be seen.”
