Example complaints

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

“At 150k miles, experienced no crank, no start. Tow to dealer, and I had already done some triage. They did 2 hrs of troubleshooting problems that were not even related, so I took the car back. Found a trust worthy mechanic and his diag suggested the scm burned out taking the PCM and ECM along with it. The cost would have been in the $6000 range as he stated a %40 failure rate after 150k in alldata. He also said, if I repair it, I need to replace the steering column as well because I will just have issues down the road if I dont. The car also had a slow oil leak. …”

NHTSA complaint #11081013, filed 2018-03, 150,000 miles

“I have a used 2006 Audi A6 quattro 3.2 [when purchased in 2013 it only had 89,000 miles - currently at 111,139 miles]. Last wednesday 06/15/2016, the car refused to turn over, however, the radio, mmi, exterior/interior lights were all operable. After investigating the issue more, I realized that the electrical windows refused to raise, the dash didn't illuminate, and I was unable to place the car in neutral. Later that evening, my insurance provider sent a tow truck with a flatbed - the vehicle had to be chained to the tow truck and pulled out of my parking spot because the wheels were locked. …”

NHTSA complaint #10875681, filed 2016-06, 111,139 miles

“I have a 2006 Audi A6 3.2 quattro. It has 53,215 miles on it. So 3,215 miles after warranty expires so does the ignition coil which has been recalled on almost every model year up 2005 for the last 5-6 years. But it's not on recall for my car yet. To me if they have had a known problem with these coils that they should take care of the problem or be responsible for the repairs. They said because there is no current recall there's nothing they can do, and the fact that they have had a recall for all there cars for the last 6 years means nothing... …”

NHTSA complaint #10227866, filed 2008-05, 53,215 miles

“I bought a used 2006 Audi A6 two months before the accident. I had been using the keyless option when starting and stopping the vehicle. I stopped at a library, pushed the button twice to turn off the ignition and the vehicle's electrical system. I got out of the vehicle and noticed that it was rolling forward. I attempted to stop it; I opened the driver's door and as I was getting in the door struck a trash can in the parking lot, knocking me down. The vehicle's rear wheel caught my left heel and drug me across a curb before stopping on my left foot. …”

NHTSA complaint #10234665, filed 2008-07, 32,500 miles

“The 2005-2007 Audi A6 has an integrated dashboard system that controls and manages the audio, navigation, telephone and other non-safety related features. The same module controls the driver's side air-bag. I recently had the display module for the radio/navigation fail. This also caused the driver's side air bag system to fail. Shouldn't safety systems in a car be on separated from the entertainment systems ? This would be similar to having your seatbelts fail if the rear seat dvd player failed, or your driving lights stop working if a vanity mirror bulb burned out....I hope you get my point. …”
