“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.”
NHTSA complaint #11407450, filed 2021-04, 53,000 miles“The turbos on the car both broke at the intermediate shaft before 75,000 miles. The car was cruising on the freeway, and the moment I slowed down to take the exit, the car lost power and shut down. I had to make an emergency stop on the side of the exit with little to no room to pull over.”

All maintenance as per manual.”

I stopped for gas and the car wouldnt restart at the gas station. …”

I tried to accelerate and could not so I pulled over and the car immediately stalled and I had to have it towed to the repair shop. The issue is a result of the turbos in my vehicle are damaged.
