Driver Assist & Collision Avoidance complaints by model year
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.

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.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
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 these are known platform issues and confirmed a software update is expected from the manufacturer in July 2026. The vehicle already has the latest available software update (TSB 2079690, KD2, version 03.10.00/C) installed and the problems persist. The dealer has confirmed there is no current fix available. These failures put the driver and other road users at risk, as safety systems are non-functional during the error state with no indication of when they will restore.

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

MMI - Multi Media Interface constantly reboots about every 90 seconds. This is a safety issue since if I am backing up and the MMI reboots I lose the backup camera and when the MMI reboots I also lose collision/parking/proximity sensors. This issue started happening with my Audi on 7/26/25 and can be reproduced every time the ignition is on or car is running. From doing a quick search on the internet this is a very common problem that just started happening within the last few months with a number of 2020 model Audi's.

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.

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.

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.

Component or System that Failed or Malfunctioned: The infotainment system in my vehicle fails frequently and unpredictably. This includes both the built-in system and connected features such as Apple CarPlay and Android Auto. The system is available for inspection upon request. How Was Safety Put at Risk: The failure of the infotainment system creates multiple serious safety hazards. First, it disables navigation features, which forces drivers who rely on GPS directions to pull out their phones while driving—causing distraction and increasing the risk of accidents. More critically, when the infotainment system shuts down, it also disables parking cameras, blind-spot cameras, and collision warning alerts—all of which rely on the infotainment screen to function properly. This loss of driver assistance features compromises visibility, awareness of surroundings, and response to potential collisions. Has the Problem Been Reproduced or Confirmed by a Dealer or Independent Service Center? Yes, the issue has been reproduced and acknowledged by the dealership. However, no long-term solution has been provided, and the failure continues to occur despite software updates and attempted resets. ? Additionally, there are hundreds if not thousands of individual following TSB's and discussing potential remedies as the dealerships have no solution. The infotainment failure has been reported to the dealership (manufacturer's authorized service center), but the issue has not been inspected by law enforcement or insurance representatives at this time. No warning lights or messages typically appear prior to the failure. The system often shuts down suddenly while the vehicle is in use, without any forewarning.
