2024 Audi Q3

I am submitting this complaint because I have experienced serious safety-related concerns involving Audi vehicles, and I am extremely concerned that these issues could result in a serious accident, injury, or loss of life. My personal vehicle is a **2024 Audi Q3**, which has experienced safety-related problems involving the braking system, wheel/speed sensors, parking recognition system, and other related vehicle safety and driver-assistance systems. I also want to report a separate and extremely serious incident involving an **Audi loaner vehicle that was provided to me by the Audi dealership while my 2024 Audi Q3 was being repaired**. While I was driving the Audi loaner vehicle, **the wheel/wheel assembly came off the vehicle while it was in motion**. This was an extremely dangerous situation that could have resulted in a catastrophic accident, serious injury, or death. The loaner Audi has a different VIN from my 2024 Audi Q3. I do not currently have that VIN available, but the dealership should have records identifying the exact loaner vehicle that was assigned to me while my Q3 was being repaired. I am reporting both situations because I believe these safety concerns need to be properly documented and investigated. A wheel coming off a vehicle while it is being driven, along with the braking, wheel/sensor, parking-recognition, and related safety concerns I have experienced with my own Audi, raises very serious concerns for me. I do not want another driver or family to experience something similar. These are not simply convenience or cosmetic issues. They involve systems and components that can directly affect the safe operation and control of a vehicle and potentially put people's lives at risk. I respectfully request that NHTSA review these incidents and determine whether further investigation is warranted. I am willing to provide repair records, dealership communications, photographs, accident information, service records, and any other documentation. Thanks
