2019 Audi Q8 Complaints

I own a 2019 Audi Q8 3.0 TFSI that has been regularly maintained and serviced through authorized Audi dealerships. The abnormal engine ticking/knocking did not suddenly begin at 91,000 miles. A similar noise could be heard earlier, but it was not identified by Audi service as an internal engine/piston problem. Because the vehicle continued to be serviced by Audi, I believed the sound was related to the fuel injectors or normal engine operation. At approximately 91,000 miles, the noise became noticeably worse. At 91,623 miles, Audi San Jose diagnosed the knocking as related to the engine pistons, classified it as requiring “IMMEDIATE ATTENTION,” opened Audi TAC case SF-1690700, and confirmed that all six pistons require replacement. Audi provided a repair estimate of $22,466.21. I have since learned that Audi has acknowledged a piston-skirt issue through an 8-year/80,000-mile limited warranty extension, and I have found numerous owners reporting similar piston knocking/piston-slap a...

I have experienced multiple events in which the there is a central locking system malfunction which renders the fob, door lock button, and at times, the door handle nonfunctional and effectively traps occupants in the vehicle.

My car is a 2019 Audi Q8 3.0L V6 with only 41,831 miles. My emergency light went on and I brought it my locat Audi Dealer. The inspection revealed that the coolant pump was leaking internally, contaminating the entire vacuum system with coolant. This is not a maintenance failure or the result of owner neglect. It is a well-documented, inherent design defect in the EA839 3.0T engine platform that powers the 2019 Q8, a defect that Audi of America has acknowledged through multiple Technical Service Bulletins. Specifically, the EA839 water pump uses a vacuum-operated diaphragm to control coolant flow. When the pump's internal seals fail — as they predictably do — coolant migrates directly into the engine's vacuum system, contaminating components far beyond the pump itself. Industry experts and Audi forums alike describe this failure mode as inevitable on this platform: not a matter of if, but when. This is a design defect manifesting at a fraction of the mileage at which any reasonable...

I own a 2019 Audi Q8. The vehicle was in the dealership’s possession for approximately three (3) weeks for service. During that time, I was not informed of any significant mechanical concerns or issues. After retrieving the vehicle, it displayed an oil pressure warning while in operation. I immediately returned the vehicle to the dealership for evaluation. At that time, the dealership added oil (“topped off” the vehicle) and released it back to me without identifying or addressing the underlying cause of the warning. Following this, I made multiple attempts to have the vehicle properly diagnosed. I experienced difficulty obtaining assistance, including calls being disconnected, and I was not provided meaningful support or a thorough evaluation of the issue. Shortly after leaving the dealership, the vehicle began producing abnormal knocking noises and rapidly became unsafe to operate, requiring it to be towed. This situation presents a significant safety concern, as a sudden loss of...
