   Brake Electronics Control Unit Failure (DTC U041800): Logged active diagnostic code U041800 (implausible signal in address 812C). Dealership records confirm no permanent remedy exists, with software patches delayed into Q3 2026, leaving active braking and electronic system faults unaddressed. Electrical Grid Collapse & Parasitic Battery Drain: Vehicle experienced exterior lights activating independently during sleep mode and cyclical 300mA to 2.0A parasitic draws. Required warranty replacement of the Central Electrical Control Module (J519), Low Voltage Power Distributor Module (J1282), and primary 12V battery (RO #AUCS214055). Powertrain & Transmission Engagement Failures: Experienced Check Engine Light cycling and a total failure to engage "Park" for 20 minutes. Scanned hard factory codes P187C00 (gear actuator 3 failure), P086900, and P270800, requiring ten consecutive distance sensor calibrations. Adaptive Cruise Control & Restraints Malfunctions: ACC fails to engage due to false occupant-detection logic errors, triggering phantom rear-seat belt warnings while driving solo and throwing error messages that compromise restraint safety architecture. Liftgate Architectural Failures: Rear trunk lid fails to open or latch fully due to software conflicts with the mobile key platform, causing the control unit to lose its calibrated position.

   Mileage at time of incident: Approximately 4,000 miles Date of incident: XXX Location: [XXX] Incident description: My vehicle was in neutral while going through an automatic car wash, as instructed. When the exit signal indicated it was clear to proceed, with my foot on the brake, I shifted into drive. The vehicle accelerated on its own, without corresponding accelerator pedal input, and struck the building adjacent to the car wash. The vehicle did not exit the building on its own, so I shifted into reverse. The vehicle again accelerated on its own and struck a structural beam. I applied continuous pressure to the brake pedal throughout the incident. The vehicle did not respond immediately, but the brakes eventually engaged and brought the vehicle to a stop. The vehicle's rear obstacle-detection and automatic braking sensors, which normally engage under similar low-speed reversing conditions, did not activate at any point during this incident. The airbags also did not deploy after the vehicle struck the building. Video footage of the incident shows the vehicle moving at low speed with no visible braking response until the vehicle came to a stop. Police and fire department personnel responded to the scene. No injuries were reported. Property damage occurred to a vinyl fence, an adjacent building, and an interior wall of a business inside that building. I requested that the vehicle's Event Data Recorder (EDR) be reviewed by the dealership/manufacturer prior to any repairs, to determine throttle position, brake switch status, and sensor activity at the time of the incident. As of this report, Audi sent an engineer to inspect the vehicle on XXX and has since provided me with a rental car. I am still awaiting the results of that inspection. Components involved: Engine/motor, electronic throttle control, service brakes, parking assist/sensors, forward collision/automatic braking system I am filing this report because I was genuinely afraid for my safety INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (

   On XXX at approximately 5:00 PM, my 2025 Audi Q5 (VIN: [XXX]) initiated an unprovoked forward collision warning and emergency braking intervention while I was traveling at approximately 57–58 mph on [XXX]. Road conditions were clear and dry. Weather was sunny. Adaptive Cruise Control was not activated. I was the sole occupant of the vehicle. A vehicle was making a lawful turn onto the roadway from a T-intersection. There was substantial distance between my vehicle and the turning vehicle. No collision risk existed and no evasive action was required. Despite this, the vehicle's forward collision system overrode my control and initiated emergency braking without cause. As a result of the sudden braking and the force of the seatbelt restraint during the event, I sustained abdominal pain and lower back pain that began immediately following the incident and persisted thereafter. This incident did not occur in isolation. Prior to this event, the vehicle had already exhibited a documented pattern of electronic and driver assistance system malfunctions, including intermittent check engine warnings, repeated false-positive driver assistance alerts, power liftgate malfunctions, sunroof malfunctions, and additional electronic irregularities. All of these concerns were reported to Audi Albany prior to the emergency braking event. Following a service visit, I was told nothing further could be done. The vehicle is currently at Audi Albany undergoing inspection at the request of Audi of America, including a review of the Event Data Recorder. I am filing this complaint to ensure the incident is part of the federal safety record. A driver assistance system that initiates emergency braking at highway speed without a valid hazard present, on a vehicle with a prior history of false-positive alerts, represents a safety defect that I believe warrants federal documentation and review.

   I bought this car in 12/2025. After putting approximately 60 miles on the car, the onboard computer would not save the inputted data. Took back to dealership and update performed. Upon returning the car for this work, the adaptive cruise control would shut itself off on the way to the dealer. They could not replicate this issue. Since having the car for about 6 months the car has been in to the dealer approximately 7 times all for different warning lights including having the module needing to be replaced that controlled the A/C. The most recent problem is the vehicle locking up its brakes and rapidly fastening down on the seatbelt while driving stating a red danger message that flashes on the informatic screen and then disappears but will not show up on the MMI screen. This has happened twice in the last 10 days. Upon the first visit I was told that Audi has been having a lot of problems with the 2025 Q5 because of the computer. The car is currently back in the shop for continued safety components selectively turning off on their own and the car slamming on its brakes when there is no adverse event. There is supposed to be a patch coming out in Quarter 3 2026, but an actual update isn't set until 04/2027 per Audi service. I have stressed how not having these functions working correctly has made the car a hazard to drive as I never know when it will act appropriately. Also the lane departure feature does not always work appropriately and will try to hold in a improper travel and will jerk the wheel. I have completely turned that function off since it has tried to turn me into on coming traffic.

6. Filed Jul 3, 2026Failure Mar 28, 2026Oak Harbor, WAWarning, Assist

   The lane keeping assistance system was engaged as we were traveling at approximately 55 mph and started around a right hand curve. The system aggressively jerked the car to the left and with the wheels on the rumble strip associated with the center double yellow lines. There was traffic flowing the opposite direction and we would have been head to head with an oncoming truck had the driver not stopped the car. The car has been to the dealer, they can not reproduce any issues with the system and have asked that video be taken the next time this happens which is not feasible nor safe. I have not driven with the lane keeping assistance on since this incident, this was not the first time that I had issues with it trying to turn the car out of a lane, and I do not feel comfortable with it engaged any longer. There were no warning lights or messages.

7. Filed Jul 3, 2026Failure Jun 13, 2026Oak Harbor, WAAdaptive cruise control, Automatic emergency braking

   I had adaptive cruise control on in moderately flowing traffic on the highway. Without warning the adaptive cruise control on it's own turned off/disengaged and slammed on the brakes. I had not changed lanes nor had anyone moved in front of me. The weather was clear. My safety and the safety of those behind me was put at risk. I've taken the vehicle to the dealer and they have not been able to reproduce the issue yet. They inspected the vehicle and took it for an initial 7 mile test drive, said they didn't find any problems and tried to return the car. There were no warning lamps or messages before or after the incident. I didn't notice any when it happened as I was focused on trying to avoid an accident. Prior to the incident the adaptive cruise control has turned off multiple times with the message " Adaptive cruise assist: currently not available" for no apparent reason, but this is the first time hard breaking was applied.

   The 2025 Audi Q5 has a systemic problem with its Multi Meidia and driver assist features, such as cruise control, side mirrors, back up camera, directional maps, etc, which malfunction at inopportune times causing major distraction while driving. Audi has been aware of the problem since 2025 and had a partial patch available in 2025, but did not inform drivers nor make it available unless requested by vehicle owner. Dealers, such at the dealer we purchased our Audi Q5 from, D-Patrick, Evansville IN, did not make us aware of flaws, and kept inidicating that it was or phones or other situations which could be easily adjusted, which was false. We did not feel safe using the vehicle and conatantly look for alternatives, due to fear and safety concerns. The first incident occured immediately after pruchase of the vehicle and has continued on a repeat basis. There are numerous reviews on line with 2025 Q5 owners reporting safety concerns while operating these vehicles.

10. Filed Jun 22, 2026Failure Feb 2, 2026Silver Spring, MDVisibility/wiper

    The windshield wipers in the vehicle do not turn on automatically until the vehicle is in drive and moving forward. If I want to see in the rain so that I can leave a parking spot, I have to use the windshield wiper control lever to manually wipe the windshield. It only wipes once when the lever is depressed. This is inadequate in heavy rain. The wipers do not go on when parked even when the wiper lever has them on. I thought my wipers were working incorrectly, but when I took it in for service, the manufacturer told that is how they are designed. It is unsafe for the windshield wipers to stop when the car is parked. Drivers need the rain wiped away before driving, not just after. In addition, the wipers do not actuate when driving in reverse, such as when backing out of a parking spot.

11. Filed Jun 22, 2026Failure Feb 1, 2026Silver Spring, MDSeat belts

    The seat belts are sometimes locked when they should not be. I understand that the seat belts are designed to lock when the vehicle stops quickly, preventing the driver from leaning forward. However, sometimes my seat belts are locked while I am driving and have not made a fast stop. For example, several times the seat belts have been locked when I get to a drive up window or kiosk, and I cannot lean forward to get a parking lot ticket or interact with the kiosk. The seatbelts have also been locked when I am stopped at an intersection. The locked seat belts prevent me from leaning forward to look for vehicles at the intersection or to see around my passenger. I have to pull on the seatbelt a few times and release to get the belt to unlock and let me lean forward.

    The airbag light and the driving assistance warning lights appeared on the dashboard randomly one day. I took the vehicle to the dealership (Audi of Columbia), where they kept it for a week and said the software needed to be updated. They updated it multiple times, but the car would not complete the update until the last attempt. When I picked up the car, they reported that several other 2025 Q5 (new model) vehicles were being brought in for the same issue. When I picked up the car, there were no warning lights on the dashboard. Approximately 1-2 weeks later, the same warning lights appeared on the dashboard again. I brought it to the dealership again, where they recalibrated the systems, disconnected the battery, and then cleared the fault code. That cleared the warning lights, and they planned to drop off my vehicle the next business day. While they were driving to drop off the vehicle, the warning lights came back on, so they returned it to the dealership. They have replaced the airbag control module without resolution. They have been working on my vehicle for >1 month to resolve the airbag issue.

    I purchased a new 2025 Audi Q5 Sportback on 4/13/2026. I brought my car home that day and then had to go to the hospital for surgery so didn't drive my car for two weeks. I get in my car after a couple of weeks and the engine light came on and didn't come off I took it into Audi on May 7th. Audi said I could pick up my car on Monday May 11th and said the car battery was charged and I should be good. I brought my car home and then didn't drive it again for a week. I got in my car again and the engine light came on again. I called Audi on the Thursday before Memorial day and was told I needed to bring this back in. I took it in on Tuesday, and was told this code is a known issue and Audi is putting a fix in place to update the modules. They provided me the attached from Audi. If this is a known issue, I feel this should have been provided to me about this before buying the car. I was also told to continue to drive the car and with the light on. How dangerous is that to drive a car with the engine light and ignore it. If something is seriously wrong, I won't know cause I am told to ignore. I would like to know how to return this car as a lemon has this was a known issue and they don't know when the fix will be in place. I am asking for assistance on how to proceed with Audi. I have read several reviews on line with others that have experienced the same issues over a year ago. Thank you !

    Regarding the adaptive cruise control, sometimes the system won't engage. The first time this happened a warning popped on the screen saying something about seatbelts. I've learned that the problem can be "fixed" by pulling off the road and turning the car completely off. That includes opening a door to silence the radio. The cruise has always worked afterwards. Sometimes while driving on cruise control, in a straight line, the car brakes abruptly for no apparent reason. Granted we were on the interstate and there was traffic but no reason whatsoever to brake. The cruise control is easily confused on roads with multiple lanes and sharp curves, like on [XXX] between Asheville, NC and Knoxville, TN. The car will brake abruptly, seemingly sensing a car in front of me but in a different lane. Sometimes when reengaging cruise control the speed goes not to the speed I had set but what it "sees" as the posted speed limit. This caused the car to speed up in a construction zone and slow to a speed below the prevailing speed of traffic around us.

    I am reporting a safety-related defect involving my 2025 Audi vehicle. Shortly after leasing the vehicle in 09/2025, I experienced electrical and system malfunctions while driving, including warning lights, intermittent adaptive cruise control malfunctions, erratic acceleration, sputtering, and sudden braking without warning. These issues occurred during normal driving and raised safety concerns. On 11/03/2025, the vehicle failed to start and required multiple jump starts, displaying multiple system errors including a check engine light and malfunctioning displays. During a brief attempt to drive, the steering wheel began vibrating, additional warnings appeared, and the vehicle behaved as if on rough terrain despite normal pavement. The vehicle was towed to the dealership on 11/04/2025. While there, Audi’s Technical Assistance Center (TAC) and engineers were involved, and I was informed that internal technical guidance was issued related to this issue, indicating it may not be isolated. After more than two weeks, I was told the vehicle was repaired. On 11/19/2025, immediately after pickup, it malfunctioned again at highway speed. During lane changes, the vehicle resisted steering input and attempted to keep me in the lane despite signaling, creating a loss-of-control situation that required abrupt correction. A rear crash assist malfunction warning also appeared. I returned the vehicle the same day. Although it may start and run, I do not believe it is safe to operate due to the prior loss-of-control event and continued system instability. I have been asked to drive it again to reproduce the issue, which I do not feel is safe. This may involve a defect in driver assistance and electronic control systems.

    My car was not operating effectively and was displaying many dash lights. I brought it to the local Audi dealership and they kept it for several days - they did a software update but most of the dash lights stayed on. They did an investigation and diagnostic review and they told me that the passenger seatbelt igniter needs replacement and that i could not safely transport passengers in my vehicle and they would order the part. The seatbelt igniter is a safety component and I am unable to use my vehicle safely/effectively as a family vehicle until this issue is resolved. The dealership has an order with Audi but there is an unexplained parts hold and no one can communicate any updates or ETA to me.

    My vehicle has now experienced a serious electrical malfunction a few times, including one again today. Each time, the car suddenly loses power and drops to 40 mph, the steering wheel shakes, and all warning lights come on. This is extremely dangerous and puts my safety—and the safety of others—at risk. The Car is Brand new and has about 1200 miles. I took the car in previously, and the dealership admitted they do not know how to fix the issue. Despite this, when I called again today after the problem happened, they refused to take the car in. At this point I do not feel safe driving it or having anyone else in the vehicle. This is severely impacting my daily life and mobility. I need immediate action and a resolution to this unsafe situation. I only get run around when I call Audi Fletcher Jones and my service adviser does not resolve my issue. They don't let me speak to the General Manager and they don't give me his email address. Attached are two photos. I have a video which i can submit per your request.
