FORWARD COLLISION AVOIDANCE,LANE DEPARTURE,BACK OVER PREVENTION06/10/2026
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.

Engine failed at 78,990 from an manufacturer defect that Audi knows about for the last couple of years. Audi extended warranty due to the failure to 8 years or 80K miles. The engines can lock up due to a piston failure in the scored cylinder walls causing a crash. Oil consumption is very high causing vehicle to burn oil and not pass smoke test. Please investigate these engine failure and manufacturer defects with this engine in multiple vehicles 3.0L turbo gas engine thanks

I am reporting a safety defect issue that I believe is an alternator recall waiting to happen. While driving with my children, my Audi suffered a sudden, complete electrical failure caused by what I was later told is an alternator defect. The vehicle shut off without warning. At that moment, I lost braking power, the ability to shift into neutral, and full control of the vehicle’s speed. Because of this defect, I was unable to slow or stop the car safely putting myself, my passengers, and others on the road at serious risk. I request that NHTSA investigate whether this alternator issue constitutes a recall-worthy safety defect under the Federal Motor Vehicle Safety Standards.

The vehicle is a 2020 model with less than 55k miles and experienced coolant leaks. Specifically, the water pump was faulty and leaked causing coolant liquid to leak in additional lines and gaskets. The repairs resulted into costs upwards of $5k. When I first brought into dealer, the service rep mentioned that the fluctuating coolant lines wouldn’t be an issue but I further pressed them on doing a pressure test to which the issue was discovered. This is a huge safety problem if my engine was to overheat or face and other issues on the leak. I’ve never heard of a water pump going bad so quickly.

- The water pump failed, leading to a coolant leak and potential engine overheating. The failed component is not available for inspection, as it was replaced by an independent repair shop after the dealership quoted an excessive price and could not complete the repair in a timely manner. - A failing water pump can cause engine overheating, sudden power loss, or complete engine failure while driving, which increases the risk of an accident. Additionally, I noticed the smell of coolant inside the cabin, which could indicate a leak that might pose a fire hazard or expose occupants to coolant fumes. - Yes, the issue was diagnosed by an Audi dealership (Audi Northlake), which confirmed that the water pump had failed and needed replacement. Due to their high repair quote and scheduling delays, I had the repair completed at an independent service center, which also confirmed the failure and replaced the water pump. - The issue was confirmed by an Audi dealership but was not formally inspected by Audi corporate, law enforcement, or an insurance company. - Yes, I noticed a coolant smell inside the cabin for a few days before taking it to the dealership. However, there were no warning lights or messages on the dashboard before the failure was diagnosed.

The door locking on the Audi Q8 is consistently malfunctioning, indicating either open doors or locked doors that can still be opened. This poses an urgent safety risk as it increases the potential for theft and unauthorized access to the vehicle, jeopardizing the safety of occupants and their belongings. The malfunction must be addressed immediately to prevent further safety hazards. The malfunction compromises the safety of occupants, especially children, who could potentially open the doors while the car is locked. This increases the risk of accidents and theft, posing a serious threat to everyone's safety. Urgent action is required to rectify this issue and ensure the security of the vehicle. The problem with the central locking system in the Audi Q8 has been widely reported in the Audi community and forums, yet Audi has failed to acknowledge it as a widespread issue. This negligence puts the safety of Q8 owners at risk and must be addressed promptly to prevent any further incidents. The dealership has inspected the vehicle, but urgent action is needed to identify and rectify the malfunctioning component or system causing the locking issue.

Rear back up camera and 360 cameras do not work consistently and result in difficulty in backing up the car without complete visibility. This issue is subject to recall on 2021 and 2022 models but not on 2020. I wonder why this isn’t being addressed properly by Audi and NHTSA
