Top problems in owners’ words
Verbatim from NHTSA complaints, newest first
Engine
23 reports1 fire
“Engine oil consumption, timing chain. This is a massive problem among Audi vehicles across the board. Engine oil consumption is abnormal and if unnoticed leads to engine dying in the middle of the road which is dangerous and I’ve personally had this happen to me on multiple occasions. The engines timing chain goes bad and causes the entire engine to need to be replaced which consumers have to pay for out of pocket. Damage from timing chain, rough idle, sluggish engine performance, rattling, engine failure. There are large amounts of consumers experiencing the exact same issues. Something needs to be done it’s not safe at all and Audi should be held responsible and liable to fix these issues. The engines are deteriorating at an abnormal and accelerated rate.”
Power train

“Vehicle has horrible oil consumption due to piston rings being defective upon manufacture. Vehicle will have slew of problems, including stopping in the middle of the street, risking the lives of everyone in the car. Audi Dealer knows of the problem with the model from this year (B8) and they refuse to fix.”
Fuel/propulsion system
6 reports
“ON MY CAR WHEN I'M DRIVING ANYWHERE AFTER I PUT MY CRUISE CONTROL ON IF I PRESS UP OR DOWN ON THE CRUISE CONTROL TO CHANGE THE SPEED THE CAR WILL EITHER BRAKE OR SPEED UP AND IT WON'T STOP UNTIL I HIT MY BRAKES HARD AND TURN THE CRUISE CONTROL COMPLETELY OFF WHICH IS ALSO AN ISSUE BECAUSE MY BRAKES ARE GOING OUT EXTREMELY FAST LIKE I NEED A NEW PAIR EVERY 2-3 MONTHS AND THE CAR ALSO BURNS THROUGH OIL SO QUICKLY THAT I NEED TO ADD MORE WITHIN 2-3 DAYS AFTER AN OIL CHANGE WITH NO LEAKS AND IT'S BURNING MORE OIL THAN GAS WHICH IS CLOGGING UP MY CATALYTIC CONVERTER........ AND CAUSING MY EMISSIONS TO BE BAD.....”
