2025 Audi Q5 Driver Assist & ADAS Problems

The vehicle triggers the braking system when there is nothing in the road, this has happened when turning across traffic, into parking lots, and when just driving on a road. Luckily this has not caused a crash yet but it has a high likelihood of causing a crash if not properly fixed by Audi. Occasionally the sensors stop working and the seatbelts tighten aggressively. This is especially risky because my wife is pregnant and this tightens for no reason around the baby. This has happened many times in the short time I’ve owned this vehicle.

The ADAS is not working properly. Adaptive cruise control, emergency assist, lane departure, active front assist, distance warning, traffic sign recognition, adaptive light, etc. are all not working. The check engine light is illuminated, the key fob would not open car (not a battery issue) and the seat belt tensioner is not working properly. Those ADAS features are there for a reason and that is to enhance the safety of me, my passengers and other drivers. The key fob allows quick access to my vehicle, which enhances my safety when alone or with others. The seat belt tensioner provides restraint during an accident so neither I nor my passenger will go head first into the windshield, air bags and/or steering wheel/dashboard. The problems have been confirmed with the dealership. Yes, it has been inspected by the dealership. Yes, they first appeared January 2025. My car is currently at the dealership supposedly waiting for a backordered seat belt tensioner. It has been at the dealership for 22 days and I haven't any idea of when I will be getting the vehicle back. I purchased it in October 2025. It has been driven less than 5,000 miles.

I am reporting a recurring safety defect in my 2025 Audi Q5 (VIN: [XXX] ). The vehicle has been in the dealership for approximately 42 non-consecutive days for repeated malfunctions of multiple safety systems.While driving, the vehicle displays warnings and disables the following systems: SOS, Adaptive Cruise Assist, Active Front Assist/Distance Warning, Lane Change Warning, Proactive Occupant Protection, Traffic Sign Recognition, Adaptive Light, Emergency Assist, High-Beam Assistant, Lane Departure Warning, and Distance Warning. These systems intermittently fail and become unavailable, triggering dashboard alerts and warning messages.Despite multiple repair attempts, the same failures continue to reoccur. The dealership has acknowledged the issue and stated that a fix exists; however, they advised that the necessary repair parts or software will not be available for approximately 3–6 months. I was instructed to take the vehicle back and continue driving it until the fix becomes available.I am extremely concerned about operating a vehicle with known unresolved safety defects affecting numerous driver assistance and crash prevention systems. The repeated failure of these systems significantly impacts the safe operation, reliability, and value of the vehicle. I am requesting investigation into this matter and the delay in providing a timely repair. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The audi presense seems to be too sensitive and it is available for inspection. There have been 3 times that I've been at a complete stop in the middle of the intersection waiting for the opposing traffic to stop so I can turn left and suddenly the car brakes, seat belts engage and it scares us. 2 times I had just started to turn left and the car braked (no opposing traffic) and it was so sudden the car behind me almost hit me since they were not expecting me to suddenly brake as I was turning left. The car has been inspected by 2 different dealers and they can not reproduce the issue. No other warnings.
