“Regular driving east bound on I-80 and after going up a hill my car couldn't go over 3500 rpms. Thought it was the ecu putting it into limp mode because of weather conditions. Turned out both my turbos blew at 67,000 miles and lead to total engine failure with metal shavings reaching the exhaust and loitering the oil pan.”
NHTSA complaint #11406015, filed 2021-04, 67,000 miles“My car's engine started stuttering and idling very roughly while exiting the expressway. The ec and check engine lights came on. It continued to shutter, and shake, until it shut off. It wouldn't restart, and I had to have it towed to the dealership where I purchased it. The dealer confirmed the issue, and reported the turbos had excessive play and scoring on the surface of the housing, caused by the excessive play in the turbos. Turbochargers needed to be replaced.”
NHTSA complaint #11406416, filed 2021-04, 49,693 miles“I have owned my 2015 Audi 8l for 6 months and it has started to stall whenever I start the initiation button. Often times it will just shift off causing me to have to restart it multiple times. I brought this issue up my local Audi dealership and they have acted as if they were totally unaware of this issue. Also I keep getting low pressure in my from right tire, this keeps me from being able to drive long distances as I am military stationed in an isolated area.”
NHTSA complaint #11240499, filed 2019-07, 10 miles“I was driving down the highway then my engine shutoff, it was very hard to control the car, I was able to pull over. Audi says both turbo had blown, I guess its common.”
NHTSA complaint #11306754, filed 2020-02, 110,622 miles“After getting off the highway, the engine just quit. Fortunately we were at a stop sign at the end of the off-ramp. There was no warning and we were not able to restart the car to move it out of traffic nor could we shift into neutral. Had this happened a few minutes earlier, we would have been traveling at 70 MPH. Fortunately, my son was driving, because at my age had this happened at highway speed, there is no way I could have steered it to safety without power steering. I know that this is not the first incident of this happening to this model car. …”
