With only 53,000 miles on my 2013 Audi S6 both turbo charges failed and Audi is now charging me $9,000 to replace both turbo charges which are supposed to last 100,000 to 125,000 miles. This issue occured while on the road idling at a light and caused the car not to be able to start and to shake the vehicle violently.

Transmission coolant valve failure. Audi has issued tsb for several models related to same failure mode. Coolant sprays from coolant valve onto electrical connectors internal to transmission causing corrosion within the connectors. Two fault modes. 1. vehicle fails to start as vehicle doesn't know transmission condition (neutral, park or otherwise). 2. if you can get it to start - vehicle is in limp mode service 2wks to replace failed valve and repair corroded electrical connectors within transmission

I am having a major safety issue with my car and it seems like Audi of America (aoa) does not seem to really care. It all started in Aug 2015 and a bunch of fault codes came one. The second time, I believe, was Jan 2016 and I was driving on I-95 and suddenly about 5 fault codes showed up while I was driving. I was traveling about 70mph in the middle lane. The car's steering stiffened up and I could not accelerate. Luckily no one was next to me and I was able to pull off to the shoulder. This could have been a major catastrophe if I was not able to pull over with the amount of traffic there is on I-95 including lots of semi-trucks. I turned the car off and turned it on and I slowly drove home. I also drive this car with my newborn in it everyday. I called my local dealership and flat bedded the car to them. They saw the fault codes and were obviously concerned so they talked to someone at aoa. They ended up changing a module and assured me that it was fixed. Well on June 8, 2016 it happened again. Again I was lucky because I was on back roads with no traffic. However, I did happen to have my newborn with me! I am furious because his life is in jeopardy now. I immediately call aoa instead of the dealership this time and they opened up a case. Aoa said to flatbed the car again to your local dealership. After 3 days, the dealership tells me there is a ground fault with the car. Aoa called me and said they fixed it but this is what they "assured" me of last time. I believe there is a serious issue with that car and no one should drive it. I do not want to jeopardize my life, my newborns life, or anyone else's life.aoa will not change my car for a new car. It seems to me they want to risk having a lawsuit against them should anyone get injured or die if this happens a third time. I want out of this vehicle.mileage shows it happening 3 times. Car will under factory warranty.
