2025 Audi S5 Recalls & Complaints

Incident: January 26, 2026 · Filed: September 6, 2026

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)

The Lane Keep Assist system will randomly attempt to steer into the shoulder or oncoming lane. This requires rapid correction from the driver to maintain travel within the lane. The most recent incident attempted to steer the vehicle into an oncoming school bus. Multiple repair attempts have been made by three dealers, the third of which performed a camera cleaning and ADAS calibration which was not covered under either the new vehicle warranty or the extended service contract despite being within the terms of both. The first dealer declined to test the vehicle, stating they did not have the necessary equipment to attempt a repair. The second declined to reproduce any of the issues noted at drop-off or perform any inspections beyond a "test drive" to and from the service center from the dealership. At the first two dealers, the lane keep assist was turned off when the vehicle was returned. After the final repair, the vehicle now usually stays in the middle of the lane and the top-down 360 degree camera view now accurately shows obstructions around the vehicle, and no more hidden obstacles suddenly "pop" into the rearview camera. This fault with the lane keep assist is most noticeable when using the system on two lane rural highways, though it can happen elsewhere. The indicator for the side of the vehicle being corrected changes from green to red as expected for intervention during each event. No specific fault codes are logged for this activation. This issue has been present since delivery of the vehicle. Similar loaners from the dealer provided during service do not exhibit this same fault on the same roads in the same locations.

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 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.

Below is a detailed timeline of the problems I experienced: Intermittent starting issue Over the past few months, the car has occasionally failed to start on the first attempt. It always started on the second try, so I planned to mention it at the next service visit. Complete MMI/display blackout while driving on the highway In the middle of my trip, the entire center display and instrument cluster went completely black while I was driving at highway speed. All information disappeared (speed, fuel level, navigation, radio — everything). The car continued running, but I had no visibility into critical driving data. After pulling over and restarting the vehicle, only half the screen returned. Hours later, the second half came back on its own. Catastrophic front-right tire blowout in a remote area of Texas The following day, while driving through a very remote stretch of highway, the front-right tire suddenly exploded with a loud bang. I safely pulled over and discovered the tire was completely destroyed. No spare tire provided The trunk contained only a tire inflator kit — no spare tire or temporary spare. A new tire was required. Inadequate roadside assistance experience I called Audi Roadside Assistance twice. Both representatives appeared to be reading from a script, were located in another country, and could not understand the urgency or specifics of my situation. After repeated miscommunication, I received no meaningful help and had to resolve the situation on my own at significant personal expense. When the local tire shop inspected the vehicle, the mechanic immediately pointed out severe abnormal inner tire wear on both front tires and stated that the alignment is clearly defective. He said the left front tire was also about to fail and that the car was unsafe to drive in its current condition. Both front tires had to be replaced before I could continue.

Known-Best Assesment-Piston Skirt Defect and Non-Disclosure of Prior Issues: Approximately only three months after purchase of a brand new 2025 Audi S5 on 6/11/25 , I received a letter from Audi of America acknowledging a potential piston skirt defect/failure resulting from faulty material and/or workmanship. They extended the part warranty for 8 years or 80,000 miles but this doesn't help me feel safe driving this vehicle. I was informed the defect cannot be proactively repaired and would only be addressed after failure. This instruction is unreasonable, unsafe, and contrary to the purpose of purchasing a new vehicle. Audi has previously settled piston-related class litigation, yet no one at Audi Henderson disclosed any history of piston issues during the sale. Had I been informed of this material risk, I would not have purchased the vehicle. I now feel unable to safely or confidently use this vehicle for long-distance or out-of-state travel. Upon researching it I found this: The mileage at which a piston skirt defect will cause total failure varies widely, potentially from mere miles to tens of thousands of miles, or could last the entire life of the engine if it's a minor defect. It is highly risky to drive with a known defect, as damage accumulates over time and can lead to a complete and sudden engine failure and could lead to catastrophic, potentially deadly consequences.   Factors Affecting the Rate of Worsening :The time frame for failure depends almost entirely on the nature and severity of the initial problem, as well as driving habits. * Severity of the Defect: A small scuff might not cause issues for a long time, while a cracked or broken skirt can lead to catastrophic failure very quickly (e.g., within 5 miles or even minutes). * Maintenance: Regular oil checks and changes help manage the symptoms but cannot prevent eventual failure if the defect is significant. * Early reports: Some drivers have reported problems with low-mileage vehicles.
