Our Audiu Q8 has had a host of safety issues since purchased in December 2023 and we have been denied or delayed on a buyback twice. The vehicle has been unable to be moved 3 times due to battery (12V and relay) issues that left my wife and [XXX] stranded at home. On one occasion the vehicle could not be moved by the tow service whatsoever. The charging system cable (known to cause fire hazard by Audi with open safety bulletins) created a fire in our 240 outlet box and also melted the plug and connected cable. The vehicle also continues to read road signs on exit ramps and hard brake check almost causing accidents while driving on the highway with cruise control. The feature for traffic sign recognition is tuned off but the vehicle continues to do this hard and sudden brake checking. Audi continues to drag their feet on repairs and still has not reimbursed us for electrical expenses from the fire damage over 6 weeks later.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2024 Audi Q8 verdict →
