The coolant is leaking out and onto engine. My safety was at Risk due to the car overheating and smoking. This is a on going problem that many AUDI’s had a recall for except mines. Yes the vehicle was inspected and the warning that came up was “coolant level low turn off engine”

ECU starting to malfunction as a coolant leak valve is leaking into it. There is a recall for these models but not for my specific car but I do believe my car is affected because my car has a coolant leak that I personally can’t find and my car was just worked on by Audi Indianapolis and they did not see any coolant leaks either. It was mentioned to me by another Audi A8 owner and it’s making sense to me as the way everything began to fail on my car until I detached the battery and attached it back it worked fine but sometimes the ECU will begin to fail for Adaptive Cruise Control randomly, then it will work again. These are symptoms of coolant leaking and affecting the ECU, and I can’t afford to pay for that to be fixed because it would cost more than what the car is worth but I would like to see if my car was affected by this recall because i genuinely believe this is what is happening

Audi a8 has been using large amount of coolant. However, its not running out the car. Yet im steady buying coolant because its saying its low. And when I go to put the coolant in my car it is low. So where is the coolant going? In trying to figure out where my coolant was going or why was it calling for so much I did some audi research on my vehicle and saw that it had a prior recall. I purchased this car over a year ago and the dealership didnt alert me of any recalls. I dont think my recall was fixed. Also theres been a lound noise on my suspension in the front of my vehicle on the right. I see audi had many complaints on this issue. The car with arrows for my suspension stays on. Took to dealership to get it diagnosed. They cut the lights off from the dash but the check engine light is still on. According to the forums ive read these issues on my audi are serious safety issues. There were no warning prior to the failures. I am really afraid to drive my vehicle because I dont knnow what or when if it will stall out on me in traffic or worse.

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. It has happened on several occasions where I was at locations where I was unfamiliar with and was reliant on my vehicle's GPS. The GPS issues being experienced have created major safety issues because I have been heavily distracted while driving and noticing that the GPS has lost signal. I almost have been involved in accidents as a result and have had to pull over because of it. This is something that audi needs to address.

I was hearing a thumping noise coming from the front of my car every time I braked and came to a stop. I also noticed that the car leaned forward heavily when I braked and knew this was not normal. I also noticed a vibration on my steering when when traveling at around 40-50 MPH. I took the car (2011 audi 8l) to my local audi who first said the car was fine and nothing was wrong with it. The issue continued. I took the car back to my local audi dealer and asked to take the mechanic on a ride with me so I could point out what I was hearing and noticing. The audi mechanic then said that he too noticed it and it seems to him like it was the control arms and bushings but had to fully diagnose the vehicle back at the shop, which he did. My local audi then came back and said that my lower left control control arm had to be replaced. I had them replace it, but the problem was not resolved. I took the vehicle back and they said that now my left upper control arm had to be replace, which I did. The problem was solved. A few months later I hear the same noise. I take the vehicle back to my local audi and they said that my right control arms had to be replaced, which I did. The issue was resolved. A few months go by and I hear the same noises and notice that the car is again dipping heavily in the front. I take the vehicle back to my local audi and they say that my control arms on the left side are again bad; they were replaced again. Now, about one year later I am noticing the same noise and vibrations on my steering wheel. This is a huge safety issue. I have noticed on many audi forums that many audi a8 owners are experiencing the same issues.

Control arm bushings subject to premature failure requiring frequent replacement. This results in extreme vibration and erratic handing during braking. Upper control arms were replace while under warranty but others soon failed once vehicle was out of warranty.
