I had purchases a 2021 Audi Q8 from Carmax on 10/16/2024. There was a time that I was driving at 35 mph in the left lane which I had my signal on to proceed in the turning lane when the car went into park and the crash indicator was on. I was jerked by the force. I also notice when you turn the car on there was a knocking sound. I had taken the vehicle into Westmont Audi on 11/22/2024. They had checked it out and said the noise was normal. I advised them to do a complete inspection on the vehicle while it was under warranty to make sure there was no other issues. They said everything looked great and that there were no codes. They don't know why the car had stopped. They did the 50k inspection as well. After that I start to experience indicator on for Intersection assistant malfunction please contact service, Audi pre sense; currently limited see owner's Manuel, and Rear Cross-Traffic assist: Malfunction, please contact service. At first thought it was normal but then it was persistent. On 2/11/2025 the check engine light had come on. I called the dealer on 2/12/2025 first thing in the morning. They advised me that it will be under warranty. I had dropped the car off to Westmont Audi and we went over the issues the vehicle was having. They informed me that it was under warranty. Once I left, they called and said it will not be covered. According to their investigation its two software that have to be updated. One for the pre sense and other for a misfire. The vehicle drags to pick up speed. This vehicle has been nothing but problems. The vehicle is not safe to drive because it is not 100% working properly the software's along with other issues. Also, I had them do a scan on the vehicle and there were so many codes on which I have attached them. It now will cost over $500.00 in repairs.

When my car is placed in reverse, the parking assist system is activated. The cameras are supposed to turn on to give me visibility and warnings if cars or people are approaching. Instead, the screen will go out and start blinking with a white screen. This results in an inability to safely maneuver and no camera visibility. This happens often and have been able to record 2 instances on my phone. I have reported the issue to the dealership twice and because it cannot be replicated, the issue has not been resolved. With each visit, video has been provided to service department.

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 2021 Audi Q8 verdict →
