Example complaints

“The transmission coolant valve leaked coolant on to the engine control module causing it to malfunction. The card stopped while in motion in the middle of the busy street and I was almost hit buy a semi truck. It started back up, I got it to a parking lot and it stopped again. I have found no less than 50 online complaints about this problem. Most of the complaints state that the manufacturer was aware of the problem.”

“The navigation system continuously displays a location where I am not located. This has occurred many, many times. It can occur randomly or at startup. This has been an issue for which I have taken the vehicle to my local Audi but they have been unable to identify the issue, although they have said other customers have came in complaining about the same issue. This issue is also widely documented on Audi forums. On several occasions, while driving, the GPS map lost signal. On other occasions the GPS map would not pick up my location. This happens the most. …”

“While driving on a city street my car suddenly stopped (4 lane street -- 2 going, to coming). There was very heavy traffic and I could not move the car as it would not come back on, nor could I shift the car into neutral to push it out of the way. As a result, the car remained in the middle of the road, in heavy traffic, for about three hours until the tow truck arrived. The car was towed to the local dealer where it was diagnosed as having coolant leaked into the engine wire harness and into the PCM where it shorted the pins. As a result the car was completely inoperable. …”
