2025 Audi S5 problems

“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…”

“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.”

“Since the day of delivery, this 2025 Audi S5 has experienced daily electronic and safety system failures. At least once per day, on startup, the vehicle throws 10 or more warning codes disabling safety-critical systems including blind spot monitoring, lane departure warning, forward collision avoidance, rear traffic alert, and adaptive lighting. These failures occur without warning and persist for varying durations before clearing on their own. Additionally, on 5 occasions the adaptive cruise control refused to activate, displaying a false "door open" warning with all doors and trunk confirmed closed. On 4 occasions the power trunk failed to latch using the electronic controls. The 360-degree parking camera system intermittently stops rendering surroundings, displaying only the vehicle graphic with no camera feed. The vehicle was brought to the selling dealer for service. After one hour, the dealer stated no issue was found. A battery diagnostic was requested based on a documented case of an identical 2025 S5 with the same symptoms traced to a faulty 12V battery. The dealer declined to cover the diagnostic under warranty. The service manager later acknowledged…”

“The contact owns a 2025 Audi S5. The contact stated that while driving at an undisclosed speed, the vehicle lost automotive power. There was no warning light illuminated. The vehicle failed to respond while attempting to drive. The vehicle was restarted after the failure. The vehicle was taken to the dealer; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure and informed the contact that the issue could be related to a lane switch failure. The approximate failure mileage was 8,577.”

“when starting vehicle every three or four days all safety systems fail and takes anywhere from one hour to 12 hours to reset. This forces me to drive vehicle without any safety systems i.e fwd collision, rear traffic alert, lane assist , side view mirror alerts, heads up display adaptive lighting. DEALER claims there is no fix at present and cannot repair until Manufacturer finds solution to software problem. This has happened on numerous occasions”
