My vehlice was in motion approaching a stop light. The vehicle stalled and I lost the ability to steer and brake pressue was lost. Fortunately, I was going slow enough to engage the electronic parking brake to bring the car to the stop. The car then would not restart without giving it hard gas. It would die within a minute or two. After towing to the dealership, I was told both my turbos had failed and would need to be replaced. My car only has 52,000 miles. This is a major failure for a vehicle with so few miles. In addition, Audi has issued a tsb acknlowledging the issue. I am just fortunate it happened for me at such low speeds. I can't imagine being on the highway when this happened.

The check engine light came on and I drove a very short distance to return home during which odd noise came from the engine. Diagnostics show that one of two turbos failed due a failure of the lubrication system for the turbos.

Luckily there was no one behind me when the car died, and that I was in the right lane and was able to limp onto the shoulder. Waited for tow truck.

I was trailing my wife and children home one evening when the car began to stall on her at an intersection. I signaled for her to pull into a nearby gas station so I could take a closer look at the car. As the idling got rougher, it finally stalled out completely and would not restart. We had it towed to a local dealer, where they incorrectly diagnosed the car and said it needed a crankcase ventilation valve. I was called and told that the car had been repaired $3,500 later. When I arrived, the car still had the same symptoms. I refused to drive the car home in the current condition even though Audi said the car was safe to drive. They rediagnosed the car and said the turbos were going out and needed to be replaced. Clearly, this is a manufacturer's defect that's eventually going to get someone killed or seriously injuried. Because these parts fail without warning and Audi is putting a patch on them telling and customers that the cars are safe to drive is irresponsible, extremely dangerous, and need to be addressed immediately!

Driving with my 3 kids on the highway, the car lost power and stalled. Wouldn't start. After research, found out I was the next in a long line of folks with a 4.0T engine turbo failure. Audi has a tsb https://static.NHTSA.gov/ODI/tsbs/2018/mc-10153123-9999.pdf but the issue stems from faulty engineering of an oil strainer. Car has full dealer maintained service records. Bought the car used from a dealer. Failed less than 500 miles after purchase. Mileage is 82000. Please help hold Audi accountable for a known safety issue affecting all cars with the 4.0T.

My vehicle experienced catastrophic failure related to the following Audi tsb & NHTSA documented bulletins and complaints: NHTSA 1-888-327-4236 NHTSA id 10118418 tsb id A211724 2044640 & tsb 2040644/10 for replacement of the oil separator - $254 (with free shipping) from audiusaparts.com. You will want part number 079-103-542-E. amidst the numerous complaints from other Audi owners the dealer is unwilling to be accountable for the damages nor willing to perform the needed repairs when the vehicle is under factory warranty. This places the burden on the vehicle owner (excess of $11,000 of repairs) to experience the failure and be placed in harms way wherever the vehicle should be at that time. My vehicle at this time was in motion in city driving forcing me to pull over unexpectedly off the road. I am asking to to hold Audi of America accountable for this known documented issue and make repairs prior to the failure firstly and secondly covering the expenses related to the failure for my vehicle after the vehicle is out of warranty for failure to do so initially.

Smelling of engine coolant. After driving for an hour, you can see steam coming from the hood but no leak.

Driving at speed limit on us highway in heavy traffic in the near northern suburbs of Chicago, experienced sudden loss of power. Vehicle began running very rough and eventually stalled in left lane. Sudden lack of power, stall and unanticipated loss of speed nearly caused accident and did cause major traffic back up. Vehicle was towed to local shop. Diagnosis determined cause of sudden power loss was damaged turbochargers (X2). Turbo impeller bearings were completely destroyed due to lubrication starvation, which caused disintegration of turbocharger impellers. Shop indicated this is a known problem with the Audi (vag) 4.0 twin turbo V-8 engines. Supporting this notion, the dealer had the turbos and associated repair parts in stock (over $6,000 of parts). Vehicle is meticulously maintained by certified Audi dealer. Vehicle indicated about 63,000 miles on odometer at time of incident. Vag uses this engine in several models across the Audi line: S6, S7, RS7, A8, and S8 (some modifications between some models).
