In XXX, my 2017 Audi Q7 3.0T unexpectedly lost engine power while traveling approximately 70 mph on a highway in [XXX]. A "Drive System Malfunction" warning appeared. The driver pulled over, shut off the engine, and restarted it; the vehicle then drove normally. The sudden reduction in power at highway speed created a risk of collision with surrounding traffic. The precise cause is UNKNOWN. I reported the highway-speed loss of power and warning to Audi Wilmington. At its XXX visit (102,255 miles), the dealership documented the warning and multiple engine misfire codes. It identified a vacuum leak at a broken oil-fill pipe neck, replaced the pipe, cleared codes, and reported no issue during…

I was backing out of a retail shopping parking lot and heard a loud bang, then a horrible noise from the front driver side. The car went on a lock down - was useless. The front driver wheel was pushed out and we could see control arms. broken underneath. I had no warning, no indicators on the dash- this was catastrophic. I was stopping traffic from passing and required police assistance. The car had was towed via flatbed to a Firestone repair shop. As mentioned, no warning - I am certainly glad I was just backing out and not driving on the highway.

The vehicle has a recurring electrical failure involving the camshaft position sensor circuit (DTC P0365). The sensor itself is functional, but the wiring harness leading to the sensor develops internal copper fatigue due to a design flaw in the factory routing. The harness is bent tightly behind the passenger-side cylinder head, causing vibration-induced internal wire breakage that is invisible externally. This failure is well known to Audi dealers and has been reproduced and confirmed by multiple service centers. The problem is not caused by the sensor, plug, or engine components. It is caused by the wiring harness design, which repeatedly fails in the same 6â10 inch section. The defect…

The 2017 Audi Q7 Prestige was purchased on November 7,2016. Since the purchase, all service was provided by one or the other of two Audi dealerships. During this period, the Audi recommended 10K, 20K,30K, 40K, 50K, 60K, 70K, and 80K mile services had all been performed. In the almost ten years that I owned the car, the oil and oil filter were changed 11 times at one or the other of the two dealerships. The mileage interval between oil changes was 6,383 miles on average with a maximum interval on 8,177 miles; the time interval between oil changes was 320 days on average with a maximum of 399 days. The engine oil cooler valve had shorted out internally and was replaced in April 2025 at 58,225…

My 2017 Audi Q7 with the 3.0T engine has experienced repeated engine/ignition system failures. The vehicle displays a "System Malfunction" warning light accompanied by shaking and stalling. This same malfunction has occurred at least 3 separate times over the past few years. Each time, a repair shop diagnosed and replaced faulty ignition coils, and the vehicle ran normally for a period of time before the identical malfunction returned. The vehicle is currently inoperable due to the most recent occurrence. This creates a safety risk because the stalling and shaking can occur while driving, with no clear warning beyond the malfunction light appearing at the same time as the symptoms begin. A…

On my 2017 Audi Q7 with 93169 miles, I am getting the error message along with a warning lamp that states: "Front right side marker light defective." The light actually works however I am getting this message. If the light were to actually go out it would affect the safety of my vehicle. I hear this is a common issue with the 2017 Audi Q7s and is very costly to fix at the dealer because the entire headlight assembly is usually replaced by the dealer. My vehicle is available for inspection if needed.
