   Due to a leak in the rear axle that is connected to the differential, it caused the entire differential to fail. The bearing within the differential completely failed due to contaminated oil. The Q8s are known to have this occur but only in year models 2020-2022. My Q8 is a 2019 and Audi is aware of these issues given technical service bulletins available but doesnt want to take responsibility as this may be a continuing manufacturing issue arising. My vehicle only has 65k…

   Driving vehicle at a low/medium rate of speed, and car completely shut off without warning. Check engine light appeared after restarting the vehicle. This is the second time this has happened to me since November 2022. I filed a report then as well. This car should not be allowed on the road and Audi should be forced to buy it back. The vehicle has less than 35,000 miles. Dealer has not confirmed what the issue is this time.

    I purchased a used 2019 Audi Q8 Prestige Plus, with Sportline Pkg on 9/7/21. Car had approx. 18,500 miles. The car attempts to shut off when deaccelerating at any speed below 3000 rpm. There is also a significant throttle delay between the time you push the gas pedal and when the engine responds. To be clear the car is in Dynamic mode and the Start/Stop mode is deactivated. It appears that under certain conditions the car is trying to determine if it should shut down or…

    Our a8 has issues with lag time when accelerating from a stop or a slow speed of less then 10 mph. The vehicle seems to stop running prior to a full stop and if the accelerator is depressed nothing happens for about 5 seconds. This is extremely dangerous and leaves us at risk of being injured or killed. This issue started just a few months after purchase and has gotten continually worse. We have also encountered this issue even after a full stop and then trying to accelerate…
