2020 Audi Q8

I am reporting a severe safety hazard on my 2020 Audi Q8 directly caused by the software update for NHTSA Recall 25V900 (Audi 90TV). The recall shows as "completed" on my VIN, but it left the vehicle with an active driver assistance defect that did not exist before. No accident has occurred, but there is a severe risk of a crash. Following the recall, the Audi Side Assist (blind-spot monitoring) behavior changed dangerously. When I signal a lane change while a vehicle is in my blind spot, the mirror LEDs blink only 3 times and then return to a solid, dim state—even though the vehicle is still actively there. If you miss that brief 3-blink window, the dim LED falsely implies the lane is clear. This has caused 3 separate highway close calls (no crash occurred) where I almost merged into a vehicle because the warning period is inadequately short. This defect followed a catastrophic failure during the recall execution. I dropped the car at Audi Chantilly on Jan 13, 2026. When picked up on Jan 29, the lane-keep assist was broken (bouncing the vehicle left and right between lanes) and an SOS malfunction light was on. It took the dealer over 2 additional months to "fix" the corrupted camera/localization modules, finally returning the car in early April. While the major module errors are gone, the underlying side assist logic remains broken and hazardous. Because of a bitter, 3-month waiting experience where the vehicle was degraded, I do not trust Audi Chantilly to fix this. I need guidance on how to compel Audi to investigate this post-recall software defect and allow me to have it corrected at a different dealership.

The contact owns a 2020 Audi Q8. The contact stated while driving approximately 10 MPH and making a left turn, the vehicle independently activated the brakes, and the driver and passenger side seat belts tightened. The contact stated that there was a RED warning light illuminated. The contact stated that she had used the left turn signal. The contact stated that failure had occurred 3 other times while making a left turn with the left turn signal engaged. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the turn assist intervention safety feature had independently engaged and a software update was needed. The vehicle was not repaired. Additionally, the contact stated that there was an intermittent failure with the front view and rear-view cameras. The contact stated during the failure, the image on the screen either froze or flickered. The manufacturer was informed of the failure. The failure mileage was approximately 60,000.
