Notes: The 3rd generation A8 got off to a slow start. Really slow, like "limp home" slow thanks to leaking antifreeze frying the engine's control modules. Thankfully the problem was recalled in September 2016.

problem #2

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. This caused a very unsafe condition as there were no warning signs, the car just shut down and would not restart or engage the neutral gear in order for me to get out of the middle of the road. This seems to be a common thing and something that should require Audi to address via a recall in order to replace the affected part(s) before something like this happens or require Audi to make appropriate repairs to those affected by this common and dangerous fault. Below is a link I found in which other individuals complain about the very issue.

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.
