I was making a left hand turn at an intersection with no cars in immediate proximity to my car and the emergency braking system activated violently causing the car to shut off. The pre sense light came on the dashboard. This happened 3 different times. I went to Freehold Audi and they stated the pre sense was doing its job. I reported this to Audi Headquarters last week and a report was written. Other electrical issues started happening, the lane change sensor was going off randomly, the windshield wipers were going off randomly. I traded the car in yesterday to Lexus of Eatontown. They said they were going to sell the Audi retail, I’m thinking to the auction. The car has less than 10,000 miles on it. I informed them about the issues I was having with the car but I’m worried they will sell it to someone without repairing the pre sense issue. I do not want anyone to get hurt in this vehicle. I hurt my neck and chest when the car violently stopped, so did my son. Someone could have easily rear ended me.

I am filing this safety complaint regarding my 2025 Audi S5, VIN [XXX]. Since taking delivery on [XXX], the vehicle has experienced repeated and intermittent malfunctions involving the driver-assistance and steering systems. On numerous occasions, the Lane Departure Warning/Lane Assist system has applied unexpected and excessive steering input. When attempting to change lanes, including while using the turn signal, the vehicle has at times attempted to steer back toward the original lane. The system has also made intrusive steering corrections while I am already traveling within my lane. These events can be unpredictable and create concern that the vehicle may unexpectedly alter my intended steering direction. The vehicle also repeatedly displays warnings stating that driver-assistance systems are currently limited or unavailable. These warnings have occurred in both rainy and clear/dry conditions and have occurred while the vehicle is being driven at highway speeds. In addition, I have repeatedly experienced a clunking sensation/noise through the steering/front axle area during sharp turns, full-lock steering, parking maneuvers, and roundabouts. The vehicle has been presented to an authorized Audi dealership multiple times for these recurring concerns. A software update was performed in August 2026. The vehicle initially appeared improved, but the driver-assistance and steering symptoms returned shortly afterward and have continued. These are recurring, intermittent safety-related problems, not a single isolated event. I am concerned that unpredictable steering intervention and repeated driver-assistance system failures could contribute to loss of vehicle control or a collision. I am requesting that NHTSA document and investigate these recurring safety concerns. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
