Example complaints

“On 09apr2021 I was driving on my way to pick up my dogs from daycare. During my ride the car seemed hesitant with power. When I arrived at the daycare and parked the car essentially seemed like it was choking and at one point completely shut off on it's own. After I picked up my dog I tried starting the car and it took 3 attempts for it to start. On the way home I had to try and keep the car in motion in order to keep the engine on, so every red light was a game. Moving though rush our in the city was very difficult and the care nearly died 3 times. …”

NHTSA complaint #11414235, filed 2021-04, 40,246 miles

“I was accelerating with traffic while on an on ramp and merging into busy traffic on the interstate, when suddenly I lost power and my car began to decelerate at a rapid pace. There was no throttle when the gas pedal was being pressed. Seconds after that I lost power to the car. Luckily, I was able to put my hazards and coast through 2 lanes of traffic to the shoulder. During which time, I had no power steering and had to fight to move the wheel. I had the car brought to my Audi mechanic who said it sounds like your turbos blew and that was indeed the case. …”

NHTSA complaint #11406182, filed 2021-04, 81,000 miles

“Both my turbos failed on my car on christmas day in 2019. I was coming home from dropping off my daughter 90 minutes away. After leaving the highway and starting to move once the light turned green, my car decided to completely stall. I was able to pull over the to shoulder as I was coming to a stop as I was on a one lane road. My car was towed and it was determined that my car had both turbos fail. I received my car back a month later and since then have had a coolant loss issue as well as a surge issue. The coolant loss issue requires me to put 4 ounce of coolant into my car every morning. …”

NHTSA complaint #11406277, filed 2021-04, 76,000 miles

“Power significantly reduced. Clear loss of boost. Eventual complete engine stall. I was fortunate to have been pulling into a parking spot when the engine cut off uncommanded. The car had to be towed to a repair shop. It was later determined the turbos had failed due to a loss of oil supply. The oil supply is cut off due to the singular turbo oil screen being clogged. Regular oil changes are documented at correct intervals. Audi after the middle of my2016 installed a revised turbo oil screen to help prevent this from happening. …”

NHTSA complaint #11406256, filed 2021-04, 56,000 miles

“Oil screen interior of engine (non-serviceable) clogged which prevented turbo chargers from receiving oil. Both turbo chargers failed which causes engine to stall. Was driving at 25 MPH on two lane city street. Engine died, power was lost, and steered vehicle to avoid collision with brick mailbox. Brought vehicle to a stop in roadway (no shoulder) but was blocking traffic. Car would not restart. Towed vehicle to Audi dealer who diagnosed turbo failure from clogged oil screen and presented a $12,732.74 quote for labor and replacement turbo chargers. …”
