On October 14, 2026, while driving my 2025 Audi Q5 on a busy freeway at approximately 57 mph, the vehicle suddenly activated emergency braking and rapidly slowed/stopped without warning. At the same time, the seat belt tightened extremely forcefully around my body, restricting my movement and making it difficult to breathe. The instrument cluster then displayed “Emergency assist: canceled.” I believe the malfunction involved the vehicle’s emergency/driver-assistance braking system and restraint system. The vehicle is available for inspection upon request. The sudden braking created an immediate risk of a serious rear-end collision because the vehicle unexpectedly slowed/stopped in freeway traffic. I was also physically restrained by the seat belt during the event and unable to move normally. This specific freeway incident has not yet been reproduced or confirmed by the dealer. I reported it to Audi Fremont immediately and requested inspection. The vehicle has previously been serviced for other unresolved safety-related issues, including a parking-related condition acknowledged by Audi as a Pending Service Solution with no repair currently available. There were no warning lamps or messages immediately before the sudden braking event. Afterward, once I was safely able to do so, I photographed the instrument cluster displaying “Emergency assist: canceled.”

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.

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.

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.

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.

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.

Adaptive cruise control not working....,Intermitently shutting off. This is coinciding with numerous engine, oil and gas warning lights going off in the Audi MMI system. Lead tech at Audi dealership in Norwell MA is telling me that this is a well known issue with the 2025 Audi Q5 needing a software update that will not be available until sometime in the 3rd quarter
