AIR BAGS
The contact owns a 2024 Audi S5. The contact stated that while his wife was seated in the front passenger’s seat with dam clothing after a workout, the air bag malfunction warning light would illuminate. The contact's wife had to sit on a towel while seated in the passenger’s seat to activate the air bags, and to turn off the warning light. The vehicle was taken to the dealer to be diagnosed. The vehicle was not repaired. The manufacturer was made aware of the failure and opened a case. The manufacturer stated that the air bag sensor was not designed to activate if the seat was affected by moisture. The failure mileage was approximately 6,000.

ELECTRICAL SYSTEM
I began my lease for a brand-new 2025 Audi S5 on July 14, 2025. The vehicle was delivered with a dent in the door, which the dealer repaired before I could take possession. The dent repair was completed on July 22, 2025, at which time I took delivery. On July 23, I informed my sales representative that the SOS/eCall emergency communications system was not functioning. This safety feature, designed to automatically contact emergency services after a crash, has never worked since delivery. I returned the vehicle to the selling dealer on July 28, 2025. As of August 7, 2025, the vehicle remains in the dealer’s service department awaiting repair of the SOS module. No firm completion date has been provided. This defect means the vehicle cannot automatically summon emergency assistance in the event of an accident, creating a significant safety risk to occupants.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER, BACK OVER PREVENTION: WARNINGS
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.

BACK OVER PREVENTION: WARNINGS, UNKNOWN OR OTHER, FORWARD COLLISION AVOIDANCE: WARNINGS
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.

ELECTRICAL SYSTEM
Audi MMI reboots constantly while the car is one. There is about 30 seconds between each reboot. This causes certain safety features like the backup camera to stop working when in use. I am not sure what the cause is but this seems to be a more common issue with the 2020 Audi's.

BACK OVER PREVENTION: WARNINGS, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
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.

UNKNOWN OR OTHER, BACK OVER PREVENTION: WARNINGS
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.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER, BACK OVER PREVENTION: WARNINGS
"The MMI spontaneously reboots numerous times while driving. When the reboots happen, the screen goes black and key systems such as the backup camera, rear obstacle detection, and navigation, become unavailable until the reboot completes and the systems reload. The reboots have affected other sensors/systems in the car like resetting my stored tire pressure values resulting in a TPMS malfunction warning and blocking use of the SOS call feature resulting in a SOS system malfunction warning. Restoring functionality after the reboots requires user input to get through the loading screens. It’s been happening since I purchased the car less than a week ago. I’m unsure of how long the previous owner dealt with this issue. Factory resets prescribed by the dealer do not resolve this issue. This appears to be a widespread issue based on the numerous reports found on user forums online, affecting the same model year vehicles (for multiple examples, refer to [XXX] ). It is also interesting that most of the users experiencing this issue, also report it starting around the same time (Jan/Feb 2025), and they all have similar software versions, and likely production dates. This should be considered a safety issue, as the reboots can happen in the middle of a reverse parking maneuver, and they render the backup camera and obstacle detection sensors completely inoperative until the system reloads. They also impact safety on the highway, as the reboots completely disable the navigation screens, and require multiple user input to restore, while driving. Relevant TSB numbers include: TSB 2067021, TSB 2076404, TSB 2069112. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FUEL SYSTEM, GASOLINE
The contact owns a 2010 Audi S5. The contact stated that while driving at an undisclosed speed, there was an abnormal sound coming from the engine compartment, prompting the contact to pull over to the shoulder of the roadway. Upon a visual inspection of the engine compartment, the aftermarket TRQ High-Pressure Fuel Pump (FPA-63379) exploded, covering the contact in hot gasoline. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 112,000.

UNKNOWN OR OTHER
My vehicles MMI screen keeps rebooting every 90 seconds, this makes hands free calling, multimedia functions, cameras etc non functional while driving. I have an appt with the dealership next week, but I'm seeing a lot of negative experiences regarding Audi's acceptance of this flaw, leading to large expenses put on the owner. Safety concerns are low, but still exist, inability to use navigation, cameras and hands free calling is not ideal, but not overwhelmingly unsafe as other options exist. My car has not been inspected yet, appointment has been made with an Audi service center though. There were no warning lights or indicators of this failing, the multimedia interface screen simply blacks out and reboots every 90 seconds. (I timed them, it is precise)

ELECTRICAL SYSTEM, UNKNOWN OR OTHER, BACK OVER PREVENTION: WARNINGS
The MMI spontaneously reboots numerous times while driving. When the reboots happen, the screen goes black and key systems such as the backup camera, rear obstacle detection, and navigation, become unavailable until the reboot completes and the systems reload. The last few days this issue has gone from happening once or maybe twice a day to almost every single minute I am driving the vehicle. Completely unacceptable and dangerous! Restoring functionality requires user input to get through the loading screens. The issue started in mid 2024 and the vehicle has been inspected by the Audi dealership (06/25), who verified the concern and attempted a factory reset (which did not solve the issue), and they continue to claim there's nothing they can do since their OBD scans return no fault codes, even though there are numerous TSBs (filed with NHTSA) that point to available software updates that should be applied to address infotainment-related issues. This appears to be a widespread issue based on the numerous reports found on user forums online, affecting the same model year vehicles (for multiple examples, refer to [XXX] ). It is also interesting that most of the users experiencing this issue, also report it starting around the same time and they all have similar software versions, and likely production dates. This should be considered a safety issue, as the reboots can happen in the middle of a reverse parking maneuver, and they render the backup camera and obstacle detection sensors completely inoperative until the system reloads. They also impact safety on the highway, as the reboots completely disable the navigation screens, and require multiple user input to restore, while driving. Please Audi, do the right thing and fix this issue! Recall these vehicles! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE
To Whom It May Concern, I am submitting this complaint to report a mechanical issue with my 2018 Audi S5 Sportback. Around 57,000 miles, the engine began making a noticeable ticking noise, which I have been advised is due to failing rocker arms. This issue has raised serious concerns, as it can lead to engine misfires, reduced performance, and potentially catastrophic engine damage if left unresolved. The problem appeared without warning, despite regular maintenance and no prior engine alerts. I believe this may be a defect affecting other Audi models with similar engines, and I urge the NHTSA to investigate whether a recall or technical service bulletin should be issued.

ELECTRICAL SYSTEM
I own a 2020 Audi S5. The central infotainment screen (MMI) has been randomly restarting while driving. At first, it only happened occasionally, but the issue has gotten significantly worse. It now restarts every 5 to 10 minutes during normal driving. When the screen reboots, I temporarily lose access to important vehicle functions, including the backup camera, navigation, and audio controls. This creates a safety concern, especially when reversing or relying on the screen for directions or alerts. Audi has not provided a permanent solution, and I’ve seen others report similar issues online. This seems like a widespread defect affecting visibility and driver safety.

For the past 6 months, I have experiencing Audi MMI reboots on every single drive. It is rather dangerous as if I am navigating using car navigation and suddenly lost connection to the route. I had few instances when I was backing up to a driveway or garage, the backup camera shuts down during backing as MMI needs reboot. There are many others online having the same issue. This is a safety issue which Audi needs to address at their own expense.
