Volkswagen Group of America, Inc. (Audi) is recalling certain 2025 Q5, Q5 Sportback, SQ5, and SQ5 Sportback vehicles. The driver and front passenger seat belts may have been manufactured incorrectly, and fail to properly restrain occupants during a crash.
The NEW vehicle keeps showing a warning light on the dash saying that the rear wheel bolts are loose two accidents have occurred in a 60 day period, the vehicle has been in for service multiple times and Audi has not found a fix for the safety light warning or found the loose bolts or suspension break issues. The have ignored a vehicle defect notice sent and lawyered up as soon as I said the vehicle was a lemon.
I bought a late model Audi Q5 2025 late February 2026. the one I bought was a loaner with 8K miles on it, list 60k, paid 48K for it. late April, we were in the mountains of western NC and were on a windy 2 lane mountain road after midnight with no cell service and nowhere to pull off. 7 warning lights came on, the most concerning was to immediately pull over and shut off the engine. We could not do this. The steering wheel was shaking and the climate systems shut off. All ABS were non functional. We drove the last half hour to the house, put the car in the garage and figured it would need to be towed the next day. The next morning, I turned it on and all was cleared out. I took it to the dealer when back in SC, but they could not find anything. it is now mid October, it has happened 4 other times since then. all in NC except for once on [XXX] but I was near exit [XXX] so made it home. It happened twice in a week late July. it was 98 outside the first time, I had an hour to go and it was incredibly hot in the car. with no ac. my two dogs were very stressed by the time we got to the house. Again, in the garage, all clear the next morning. It happened on the way home, now it's 99 out. I turned off the car in a parking lot, waited 15 minutes, turned it on, all clear and we got home fine. My service person said there was a "major software upgrade" coming out and that was all the car needed. they got me in early before it was released and had the car for 4 days. It took 5 tries to get the upgrade. I was told this was it, all was fine. next time I was on a steep downhill in NC. had to hold tightly to the wheel it was shaking so much, abs working, maneuverability seemed compromised. I was scared to death. This time it took over a week and because they could not find the fault code, nothing done. Given the research I have done, I am sure the dealer knew about these issues when I bought the car or certainly during the emails detailing the other incidents.

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.
