Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“There have been no accidents so far however my warning display on my instrument cluster on my 2001 Audi A4 1.8t has be continually fading in warm weather leaving me unable to see if there are any problems with my car. This can become very serious if I can't see if something major comes up that needs immediate attention.”
NHTSA complaint #10267270, filed 2009-04, 88,153 miles“The digital instrument cluster is not working properly on my 2001 Audi A4 1.8t. You can only see half the screen on the center display that notifies you when the car needs to be serviced and if any major problems are occurring I feel this is a safety issue and Audi should recall and repair any cars with this malfunction because I have read several reviews of the same problem so obviously it is something they should look into.”
NHTSA complaint #10330101, filed 2010-05, 35,000 miles“An ignition coil on my 2001 Audi A4 failed, causing an extreme loss of power, poor steering and braking. The potential for an accident exists, especially if driving at a higher speed, or in poor weather conditions (as I was). The dealer was authorized to only repair the 1 failed coil, and I am at risk for further failures, a safety concern for me.”
NHTSA complaint #10005692, filed 2003-02, 8,519 miles“For the second time on my Audi A4 turbo the ignition coil failed,causing car to completely loose power on busy road. My vehicle only has 12,500 miles on it and the dealership will not change all coils. They also refuse to do a trade in on the vehicle”
NHTSA complaint #10002869, filed 2003-01, 11,900 miles“(1) I have had 3 Audi A4's that have had this same issue!!! 98', 99.5' and 01.5' A4's. Below in the incident date, I stated the date when I purchased my current car... This does not include the two previous A4's I had with the exact same problem years ago. (2) the lcd screen in the instrument cluster has several pixels that die out and make the screen blurry or blank! This is extremely important for the driver to know what is wrong with the car when a problem occurs! Also states in the owners manual it is for safety issues and the driver needs to be aware of these situations at all times. …”
