NHTSA Complaint #11635909 — 2017 AUDI Q7

Drive system malfunction warning while driving on the highway at 75 mph and the car began sputtering, lugging, jerking and had to be manually shifted to get it safely off the highway. If we had been in traffic we would have been rear ended as the car drastically lost speed on the highway. Dealership initial diagnosis was a misfire in cylinder 4. Upon further inspection we were told that a piece of the exhaust manifold had broken off resulting in catastrophic engine failure and we needed to replace the long block at a quote of $32,000. Car had been serviced only at the Audi dealer and all Audi care maintenance had been completed. We had informed the dealer that the car was burning oil on two previous service visits and we were adding a quart every 1000 miles or so and we were told that was normal for a 2017 Q7 with over 80,000 miles on it. Last service inspection and Audi care package in September 2024 we were told the car was in great shape. Catastrophic engine failure in December 2024.
