Example complaints

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

“In november of 2010, I was driving in my 2004 1.8 Audi TT at approximately 45 miles per hour. Without warning, the car lost all power in the middle of the road. Fortunately, the car lost power at 1:00 am or I may have been easily hit/killed by the heavy flow of daytime traffic. As it turns out, there was an ignition coil recall on my vehicle. I never received notice of such recall and as a result, was put in danger by operating a vehicle with a known defect and suffered over two thousand dollars in related repair expense. …”

“The car was having electrical problems, appear related to instrument cluster failure. I scheduled with Audi to evaluate faulty gas gauge and radio staying on after key removed. Anyhow, before I could get it into Audi, the car while driving jerked violently and then would not shift gears. It was lucky I was not going very fast as I was on windy roads with cliffs. I could have been seriously injured or dead had the car lost control. There have been recalls on the dsg and clutch assembly for my model car, but they don't show up on my record with Audi. …”
