2025 Audi Q3 Reliability Score & Common Problems

While driving my brand new 4-day old 2025 Audi Q3 at highway speeds, the vehicle suddenly lost engine power and shut off without warning. At the time of the incident the fuel gauge indicated approximately 1/4 tank remaining and there were no prior warnings. I was forced to pull over in traffic, creating a dangerous situation. The vehicle had to be towed to the dealership. I was initially told the vehicle had "run out of gas", despite the fuel gauge showing fuel remaining. This same failure occurred a second time under similar conditions, again while driving at highway speeds with fuel indicated on the gauge. The vehicle stalled and shut off unexpectedly, requiring another tow. During the second repair visit, Audi technicians confirmed that the fuel tank's internal level sensor was defective and that the vehicle was inaccurately reporting fuel levels. Audi's Technical Assistance Center instructed the dealer to replace the entire fuel tank assembly on this brand-new vehicle. This defect caused repeated loss of engine power while driving, creating a serious safety risk to myself and other motorists. I no longer feel the vehicle is safe to operate due to the risk of sudden stalling without warning.

I purchased a new 2025 Audi Q3 8/18/25 and immediately experienced a potential safety issue with the driver’s seat. The seat structure did not provide stable or secure support, which affected my ability to maintain proper posture and full control of the vehicle while driving. This created concerns about safe operation, particularly during braking, steering, and longer periods of driving. I reported the issue promptly and requested a warranty inspection. However, Audi of America issued a formal denial on October 9, 2025 without performing any inspection of the vehicle or the driver’s seat. As a result, the vehicle was never examined by an Audi technician, manufacturer representative, or any third party. Because the manufacturer refused to inspect the component and I could not safely operate the vehicle, I was forced to exit the vehicle entirely. The lack of inspection prevented any determination of the root cause, potential defect, or safety risk. This procedural failure is the basis of this report.

Vehicle failed to start with many tries despite my own key fob. Initially displayed message with 'Theft' reference, then changed to "Checking remote access rights. Please wait..." on screen. Opening door triggered unexpected shocking alarm, which stopped after using fob to turn it off. Started to video record the situation after about a minute of failed start attempts. Vid lasts 41 secs until on.Two additional photos from myAudi app 'theft' & 'break-in', which was driver exiting vehicle triggering alarm. Prior issue with drivers seatbelt occurred with car in 'park' and ignition on, seat belt unexpectedly pulled occupant tight against seat. Seatbelt adjuster on seatbelt anchor point moved quickly up and down several times making whirring noises before abruptly stopping, releasing occupant after 10-15 seconds. As a 100% disabled veteran with severe neck damage this could paralyze me if happens while driving, and heart stopping shock. Vehicle in Brooklyn Service since 11th Sept. Mgr says today there are no faults in the system and no data to be collected. Even with video proof the service center lack resolution, and Mgr wanted me to pick up the car. I insisted they keep for further testing as it may need extended observation to replicate issue. I feel unsafe. My safety was put at risk due to the non-start incident happening late at night in a low lit area in Elizabeth/Newark not a good area potentially stranding me in an unsafe situation. A starting issue and an alarm malfunction, both of which are critical. This is the second safety issue in a brand new car, within 6 weeks of owning the car. There were no warning lamps, messages or other symptoms prior to failure. They first appeared after I unlocked with fob and sat inside. I caught a brief glimpse of a sentence containing the word "Theft", then unsuccessfully tried to start the car multiple times before I noticed the message telling me it was trying to check remote access rights.
