Verbatim from NHTSA complaints, newest first
“Was just driving down the highway at normal speed and my car lost all power, every like came up on the dash and disabled my power steering causing me to almost crash. Took it to the shop mechanic tells me the turbos failed due to oil screen and it will cost me $8,000 Not sure why they failed I have amazing service records on my car. This needs to be a recall.”
“the 2013 Audi 4.0T generation have a massive issue where the engine start leaking from the bottom of the crankcase where the block connects to it and to fix all these issues audi is asking a rebuild of the entire engine this issue is very common on the 2013 2014 2015 S6 S7 S8 with the 4.0T worldwide problem”
“The Mfg defrayed some of the cost of replacing the two turbos but I was charged $5,607.06 on the repair on 9/24/20. The cause of the repair was do the mfg defect and they should pay 100% of the repair. The vehicle only had 42,040 miles at the time of the turbo failure.”
“Recently learned that my car broke down on my spouse in an extremely unsafe location due to turbo failure(s) probably caused by the turbo oil inlet screen. She was on a busy street when the car shut off on her putting her in an extremely unsafe situation to move the car and wait for tow truck service. The car is still with the Audi dealership for repairs but has been confirmed that this is the likely incident and fixing it will likely prevent further issues. This car has only been to Audi certified technicians at dealerships for the entire time I've owned the car and I was never notified that this is a common occurrence in these models with the turbo. Numerous online forums are dedicated to discuss the common occurrence when researching this particular issue going back a few years, mostly astounding a recall hasn't been issued. There was no warning lamp for the issue to warn us of the impending failure.”
“Vehicle has had all recommended maintenance performed on schedule at the Audi dealer. Driving down a highway at about 73k miles, engine stopped running with no warning. Electronic systems appeared as though engine was running, but it was dead. We were extremely fortunate that this happened on a rural highway and not the big city freeway system we had recently driven through. Cause of the problem was a total engine failure, later discovered to be failure of the turbocharging system. Checking online reveals that it likely due to a defect in an oil strainer. Sudden catastrophic engine failure at only 73K miles in a dealer-maintained vehicle is a safety hazard, to the occupants of the vehicle as well as to surrounding cars that have to navigate around a suddenly powerless car.”
“Turbocharged failed while driving in afternoon traffic, leaving car stranded at heavy traffic stoplight until tow could be arranged. Failure occurred while idling at the stop light. Failed turbochargers are available for inspection. Failure was initially diagnosed / confirmed by dealership (Audi Chantilly) but due to extreme cost of repair quoted by dealer, car was transported to an independent garage for the repair. Failed turbocharger was inspected at dealership using micro-camera for diagnosis of the problem. There were no warnings, check engine lights, strange noises, loss of power, etc..; failure was total and instantaneous. Additional information: This is a totally stock vehicle, no modifications or tuning performed. It has never been raced or abused. The 'launch mode' built into the car's design (for fast acceleration from stop) has never been used on this vehicle. Put simply, this vehicle was 'babied'. For the initial life of the car, all maintenance was performed at dealership (Audi Chantilly) under service contact. Upon expiration of service contract (~65K miles) all service was performed by owner. Knowing of the turbocharger oil feed defect present…”
