2021 Audi Q8

On multiple occasions, the car states there is a steering malfunction and to stop the car immediately. Power steering fails. The last time I left the car to the dealership to have a recall serviced - it did this. I let the Audi (Fred Lavery Birmingham Michigan) know. They did not respond / did nothing. It has happens at least 10x at varying speeds (some high, med and low speed) since the day I left the dealership

I was driving my car would not accelerate on the highway and it almost caused me to get into an accident with my niece in the car. When I took the car to Audi this is what I was told my the service adviser. “Good afternoon. The technician has been looking into the vehicle and has found the cause of the issue. He has found the coolant water pump has failed internally causing coolant to leak internally into the vacuum system. This is causing the vacuum to be blocked for the turbo and thus causing the sluggish feeling when accelerating. In order to fix, the water pump and all compromised vacuum system components need to be replaced. It is a rather extensive job unfortunately.” My car only has a little over 45 thousand miles. Audi should be responsible to fix this problem because they sold this car knowing the water was faulty in these models. I recall should have been put out. I was quoted $6,000 to fix this problem.

Belt Starter Generator failure rendered car undrivable -- power steering failed while in motion. Issue is subject to Class Action Settlement in USDistrict Court, Case # 3:23-cv-02291-RK-RLS. But this should have been a recall because of danger of Injury or Death. A recall would provide notice that the notice of settlement failed to provide. This failure happened to me on March 29, 2026. Dealer is not able to do the repair work in a timely manner.

Audi Q8 failed water pump leading to severe loss of power and a major safety issue. I was merging on a very busy highway when I had loss of power with my children in the vehicle. This was alarming as I was not able to accelerate as anticipated and had no warning/notice that this was going to occur, and others around me did not know what was going on as well. This is a known complaint and issue in these vehicles and a major safety issue. Audi should stand behind their quality and it is dissapointing costly repair that shouldn’t be needed at 50 k (right outside of warranty). This issue can cause a detrimental accident.

The engine (internal mechanical failure) malfunctioned. The vehicle developed a persistent ticking/knocking noise from the engine bay, and the authorized Audi dealer diagnosed the issue as requiring a full engine replacement. The vehicle is currently available for inspection upon request. A catastrophic engine failure presents a risk of sudden loss of power, stalling, or engine seizure, which could occur while driving at speed or in traffic. This creates a potential risk of loss of vehicle control, inability to accelerate, or being stranded in unsafe conditions, endangering both the driver and other motorists. The problem was confirmed by an authorized Audi dealership, which diagnosed the vehicle and stated that a complete engine replacement is required. The estimated repair cost provided by the dealer is approximately $26,000 (so far in parts only). The vehicle has been inspected and diagnosed by an authorized Audi dealership. At this time, it has not been inspected by police or insurance representatives. Audi corporate has been contacted for review. The primary symptom was a persistent ticking noise from the engine bay, which began around late December 2025 / early January 2026. There were no immediate warning lights or dashboard messages at the onset of the noise. The noise progressively worsened, prompting dealer inspection and diagnosis.

Subject: Spontaneous Sunroof Shattering – 2021 Audi Q8 Summary: On 8/5/2025, while driving my 2021 Audi Q8 under normal conditions, the sunroof suddenly shattered without warning. There was a loud popping sound, followed by glass breaking and falling onto the closed sunroof shade. There were no visible signs of impact from external objects, and weather conditions were normal at the time of the incident. The vehicle was not involved in a collision and was being operated safely. This incident created a serious safety hazard, as the loud popping sound once the sunroof ruptured could have cause me to get into an accident. I am also lucky that the sun roof shade was closed or the pieces could have struck me inside my vehicle. I will be contacting insurance and Audi dealership regarding the damage. However, after researching online, I found similar complaints from other Audi owners, suggesting this may be a recurring issue with panoramic sunroofs across multiple models. I am reporting this to the NHTSA because I believe this could indicate a potential defect in the sunroof glass or its installation. I request an investigation into this matter to ensure the safety of other drivers who may be at risk.

Purchased my car used from Volkswagen of west islip. After a few months I was doing regular maintenance when I noticed that the brake sensor was missing and the harness was tampered with. The brake wear sensor was removed from the front driver side and a small price of wire/ conductive material was inserted into the harness to trick the cars system into on seeing the sensor in a safe and working manner. This would prevent the cars system from alerting me when the brakes need to be replaced which could have resulted in resulted in a serious accident due to brake failure. I feel like this was either deliberately done by the dealer before selling the car to save a few dollars or was overlooked during what should have been a basic safety inspection before listing the vehicle for sale. After reaching out to the dealer- they refused to fix the issue.
