2018 AUDI Q7 Power Train Problems

To Whom It May Concern, I am writing to formally report a serious and recurring safety issue involving my 2018 Audi Q7. The vehicle has experienced repeated drive system malfunctions that result in sudden loss of power, reduced acceleration, and warning messages on the dashboard such as “Drive System: Malfunction” and “Electrical System Failure.” These incidents have occurred while the vehicle was in motion, creating a hazardous situation for both the occupants and surrounding drivers. In my case, the vehicle unexpectedly lost power while driving at highway speeds, forcing me to maneuver to the shoulder with diminished control. This sudden malfunction is unpredictable and could easily result in a collision or serious injury, especially in high-speed or high-traffic conditions. Upon researching this issue, I found that numerous other 2018 Audi Q7 owners have reported similar problems. These complaints consistently cite the same symptoms, including sudden deceleration, electrical system errors, and...

Audi Quattro (differential) noise is being heard while turning the car. The problem was identified to be due to different speeds between the front and rear differential, the locking effect of the center differential can differ significantly in tight bends. – unless there is a design flaw, there should be no noise coming from the differential . this is totally unheard of from any car I have owned. Problem was reported to Audi dealership and no definite solution was offered other than changing the oil for the center differential oil and checking to see if the problem goes away. if it does not, they would do further investigation. This is an Audi Quattro differential design fault that can be very dangerous if it fails on highways or under adverse weather or at high trafficked areas. I started an incident case (Reference #06217801) with Audi USA and Regional Case Manager (MR)...

Car is consuming 1 quart of oil every 600 miles.

When I was driving and trying to make a right turn to merge into the traffic, the transmission suddenly stalled and stuck in neutral, put my car in the right lane with large traffic on the lane and forced other cars to make sudden stop. After restarting the engine multiple times, it was suspected that somehow the transmission is always in neutral while the onboard system showing it is in driving mode. I had to get out of the car to push it to a safe side road. This is all sudden while car engine is running. Initially the onboard dashboard shows Transmission Malfunction, but after restarting even that error message disappeared, while the transmission is still not engaging.

AT TIMES, THE "STOP-START" SYSTEM SEEMS TO FALTER WHEN THE VEHICLE HAS SLOWED TO ALMOST A FULL STOP, BUT NOT QUITE. IF I TRY TO ACCELERATE I GET A FEW SECONDS WHEN NOTHING HAPPENS. I FEEL THAT IT IS EITHER A TRANSMISSION CAUGHT BETWEEN SHIFTS OR AN ENGINE FALTER. I HAVE MENTIONED THIS TO THE DEALER, BUT WAS TOLD THAT "THAT'S HOW IT IS".

WHEN CAR IS PLACED IN REVERSE A "P" OR PARK IS STILL DISPLAYED IN THE INSTRUMENT PANEL. THIS HAS HAPPED SEVERAL TIMES. AUDI SERVICE WAS PROVIDED PICTURES AND VIDEO OF OCCURRENCES AND THEY SAID THEY WOULD GET BACK TO ME. THEY NEVER DID. ALSO NOW HAVE SOS MALFUNCTION WARNING DISPLAYED. CAR ONLY HAS 7K MILES ON IT.
