1 Adaptive Cruise Control problem

Failure Date: 08/15/2026

Driving 75 mph in heavy freeway traffic with no for warning at all, my car initiated auto breaking violently tightening my seatbelt two times. The steeringwheel was was also jerking left, and right like the car wasn’t sure what to do. I had both hands on the steering wheel. And was trying to stop it. The car would not allow me to take over her control. Myself and was coming to a stop. I looked into the rearview mirror worried for my life and found amazingly that nobody was directly behind me. The car’s horn was honking. The hazards were flashing. It was all kinds of lights on the dash not sure exactly what they works. It all happens so fast one seem to have had a lightning bolt and an sos med alert of some kind. This felt like it lasted 30 seconds but in hindsight, it was probably only 3 to 5 seconds as so much was processing in my brain. My wife was freaking out as it also pulled her back into her seat very violently twice the car felt like it was totally gonna fall apart in the dead middle of the freeway it would not let me control, gas brake or steering as it was getting slower and slower almost to stop. I tried to turn it to the right to get to the shoulder of the freeway. It fought me, but I was able to get it off to the side of the road once I was on the side of the road and came to a complete stop. The horn stopped honking the lights quit flashing everything on the instrument cluster went normal and the cars radio turned back on like nothing had happened. This was the most frightening experience ever as when it occurred. I was in busy freeway traffic, extremely unsafe and terrifying luckily no accident, this could have been so much worse and it could’ve caused so much to those around me not just my family and I in the car but other lives could’ve been in jeopardy as well on the freeway. After contemplating what to do I reluctantly went to the next exit which was within a 1000ft then straight to the Audi dealership in leighton, utah. I have filed a full repo.

The vehicle repeatedly disengages critical safety features, including distance warning, traffic sign recognition, adaptive cruise assist, emergency assist, and active front assist, and displays a malfunction alert. Additionally, the vehicle has abruptly stopped without any identifiable cause while traveling on a straight roadway with no surrounding traffic. The dealer provided me with a brand new 2026 Q3 two weeks ago. The vehicle exhibited the problem described, and the dealer replaced it because they were unable to resolve the issue.
