Owner report 11656169 · 2025-04-22 (April 22, 2025)

On April 2, 2025, while driving on Interstate 25, my 2021 Audi Q8 Premium Plus experienced a catastrophic engine and electrical failure. This included the generator system failing, which resulted in a complete loss of power, disabling all active safety systems (including electronic stability control, braking assist, and lane monitoring), as well as basic driving capabilities such as acceleration and steering responsiveness. The incident occurred without prior warning or diagnostic alerts, and the vehicle became immobile on the highway. The sit…

Owner report 11547234 · 2023-09-28 (September 28, 2023)

Complete loss of electrical power while driving due to faulty alternator at only 35K miles. This resulted in total loss of steering, suspension failure, and any other electrical systems in the car. Making the car almost impossible to control specially for a new driver. Apparently the issue is widespread with any Audi car or SUV equipped with a V6 3 liter engine. The repair requires the replacement of the alternator and the 12v (an in some cases 48v) battery. The issue happens suddenly with no prior warning and completely disables the vehicle wh…

The contact owns a 2021 Audi Q8. The contact stated that while driving at an undisclosed speed in the rain, the automatic braking system sensors engaged. There was an abnormal sputtering sound coming from the vehicle. The driver believed that the vehicle had struck an object. The vehicle was taken back to the local dealer, who was unable to repair the sensor, and the failure recurred. The manufacturer was contacted and filed a claim. The approximate failure mileage was 8,600.

Owner report 11565007 · 2024-01-11 (January 11, 2024)

The alternator on my Audi Q8 SUV died AS I WAS DRIVING IT, leaving my vehicle with no power. I was left to coast down the 50-60 MPH highway I was driving on into a turn lane, where the vehicle stopped and could not be restarted. My safety was put at risk because I was on a highway in a car that stopped operating suddenly and catastrophically. If I had not been able to coast into a turn lane, the car would have left me in a high-speed lane. I waited for a tow truck over two hours, the first hour inside the vehicle, the second outside on a sm…

My 2023 Audi Q8 Pre Sense collision braking system has engaged erroneously on numerous occasions under completely normal driving conditions. It’s terrifying and potentially life-threatening liability. My vehicle would consistently flash warning signals on my dash and my screen went completely black. Most recently, while driving at approximately 35 mph, the Pre Sense system activated without warning or cause. The impact was so violent I believed I had been rear-ended. No vehicle was behind me.

There is a pulsating/fluttering noise coming from the rear passenger side near side of the vehicle. Got the vehicle in July of 2023 and reported the issue in August. Dealership confirmed and performed TSB 2067759/2 (Installed 10 rubber insulator sleeves). This did not fix the problem. I noticed it is loudest when the fuel tank is low.

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.

At approximately 52,000 miles, on August 11,2026 (or earlier), my vehicle developed a coolant leak that was traced to a failed coolant shut off valve.

This resulted in the vacuum system becoming filled with coolant, compromising components that rely on vacuum pressure to function correctly. The combination of these failures , water pump contamination, coolant shut-off valve failure, and a coolant-contaminate…

At approximately 52,000 miles, on August 11,2026 (or earlier), my vehicle developed a coolant leak that was traced to a failed coolant shut off valve. The coolant shut-off valve failure allowed coolant to migrate into the vacuum harness, vacuum reservoir which contaminated the water pump. This resulted in the vacuum system becoming filled with coolant, compromising components that rely on vacuum pressure to function correctly. The combination of these failures , water pump contamination, coolant shut-off valve failure, and a coolant-contaminate…

When driving, my car had several red and yellow warning lights that came one - one for electrical system, the other for Vehicle starting malfunction and another was a battery sign. The vehicle also had delays starting. I was fearful the car would stop while driving (hopefully not on a highway or busy road) or I would be stranded somewhere because the vehicle would not start

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.

It has happens at least 10x at varying speeds (some high, med and low speed) since the day I left the dealership

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 acci…
