Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

CarComplaints.com 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.

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 2 hours until the tow truck arrived. The car was towed to the local dealer where it the dealter took 4 days to diagnose it with 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 the behind me suddenly had to break and just missed hitting my car. 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. This is a serious safety issue! dealer wants $11000 to repair it! what should I do?? loss of work and pay as car is stranded at Audi dealer! agony! embarrassment!

The contact owns a 2011 Audi A8. While driving the vehicle at various speeds, the engine warning indicator and the "do not exceed 4,000 rpms" warning indicator illuminated. The dealer diagnosed that the engine coolant was leaking through the coolant valve connection. The vehicle was not repaired. The failure mileage was 75,000.

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.

I was accelerating onto the freeway on ramp when the engine cut off. I managed to pull over to the shoulder but the check engine light and the epc light came on. I had to be towed into the dealer. There was a "coolant valve leak. The coolant migrated through a harness to the ECM and to multiple connectors thoughout the engine harness". the worst part of this situation is the extremely dangerous position I could have been in. What if the car stopped while in the fast lane, or express lanes of the freeway? this is not the first complaint of this nature on this model of Audi. Please check into this as I am sure it will cause a fatality someday.
