All driver assistance features shut down randomly when starting vehicle for at least 45 minutes. Had to drive vehicle without safety features to get home. Without lane assist-fwd collision-side collision alert-rear traffic alert etc make vehicle difficult to drive and could result in accident. Dealer and Audi are aware of problem have tried to fix twice and tell me at present there is no fix. Possible software update in future? vehicle has not been inspected by insurance or anyone other than dealer. As stated above warning lights on dashboard screen flash all driver systems are not working. System resets after shutdown in 45 minutes or so, but randomly repeats sometimes two days in a row, sometime four to five days apart.

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.

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).

Sudden reboot of the vehicle's infotainment system, which then repeats every 60-90 seconds consistently. The reboot has happened while reversing the vehicle, which results in losing view of the backup camera and parking sensors / rear cross traffic detection. This issue was originally sparse, but after 7/14 manifests 100% of the time when using the vehicle. This represents a safety issue due to the loss of rear backup camera for 30+ seconds while the infotainment reboots. No warning lights appear, no inspections have been performed by the dealer or any others.

I am writing to report a critical and recurring safety defect concerning the multi media interface (mmi) system in my Audi S5. The mmi system consistently restarts itself approximately every 90 seconds, regardless of whether the vehicle is stationary (parking) or in motion (driving). This issue presents a significant safety hazard because critical sensor information and vehicle status displays, which are shown on the infotainment screen, become unavailable during each restart cycle. During the 5-10 second period of the system restarting, the screen goes blank, and all related functions and visual aids, including parking sensor readouts, camera views (if active), and other driver assistance information, are completely inaccessible. The intermittent loss of these visual aids creates a hazardous situation, especially when maneuvering at low speeds, parking, or when relying on sensor alerts for proximity to other vehicles or obstacles. Even during normal driving, the sudden loss of the display is a distraction and removes vital information that a driver might rely on. This is particularly concerning as it affects features directly related to situational awareness and collision avoidance. The problem is persistent and has been occurring since July 2025. I have attemptedrestarting the car, checking for software updates. The issue remains unresolved and consistently compromises my ability to safely operate the vehicle.

The radio (mmi system) is rebooting while driving every 5-10 min. Dealership can't fix and is affecting safety sytems like front and rear cameras/sensors.
