Audi Q5 2025

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.

The ADAS is not working properly. Adaptive cruise control, emergency assist, lane departure, active front assist, distance warning, traffic sign recognition, adaptive light, etc. are all not working. The check engine light is illuminated, the key fob would not open car (not a battery issue) and the seat belt tensioner is not working properly. Those ADAS features are there for a reason and that is to enhance the safety of me, my passengers and other drivers. The key fob allows quick access to my vehicle, which enhances my safety when alone or with others. The seat belt tensioner provides restraint during an accident so neither I nor my passenger will go head first into the windshield, air bags and/or steering wheel/dashboard. The problems have been confirmed with the dealership. Yes, it has been inspected by the dealership. Yes, they first appeared January 2025. My car is currently at the dealership supposedly waiting for a backordered seat belt tensioner. It has been at the dealership for 22 days and I haven't any idea of when I will be getting the vehicle back. I purchased it in October 2025. It has been driven less than 5,000 miles.

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.

After the automatic start/stop system engages, the engine stalls and completely shuts off shortly after the vehicle begins moving again. This occurs after the vehicle restarts and travels only a few feet. When the stall happens, the vehicle loses power and the engine stops functioning while the car is in traffic. This has occurred two separate times: once on a busy highway and once while entering a roundabout. Both incidents created a dangerous situation where the vehicle could not maintain power in active traffic and could have resulted in a crash. A yellow emissions warning light also appeared on the dashboard. The dealer indicated that an intermittent oil pressure sensor code was present but no parts were replaced and no corrective action was taken. The dealer reset the system and stated they could not reproduce the problem. The vehicle is now being returned to me without repair despite the safety risk. An engine stall immediately after the start/stop system restarts the vehicle creates a serious hazard because the vehicle can lose power in the middle of traffic. I believe this issue may be related to the automatic start/stop system or an oil pressure sensor fault affecting engine operation.

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.

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 !

I am reporting a recurring safety defect in my 2025 Audi Q5 (VIN: [XXX] ). The vehicle has been in the dealership for approximately 42 non-consecutive days for repeated malfunctions of multiple safety systems.While driving, the vehicle displays warnings and disables the following systems: SOS, Adaptive Cruise Assist, Active Front Assist/Distance Warning, Lane Change Warning, Proactive Occupant Protection, Traffic Sign Recognition, Adaptive Light, Emergency Assist, High-Beam Assistant, Lane Departure Warning, and Distance Warning. These systems intermittently fail and become unavailable, triggering dashboard alerts and warning messages.Despite multiple repair attempts, the same failures continue to reoccur. The dealership has acknowledged the issue and stated that a fix exists; however, they advised that the necessary repair parts or software will not be available for approximately 3–6 months. I was instructed to take the vehicle back and continue driving it until the fix becomes available.I am extremely concerned about operating a vehicle with known unresolved safety defects affecting numerous driver assistance and crash prevention systems. The repeated failure of these systems significantly impacts the safe operation, reliability, and value of the vehicle. I am requesting investigation into this matter and the delay in providing a timely repair. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.

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.

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 REDACT
