What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
There was a warning message when I tried to start my car about a week before. Because it made no sense - like your tires are low - I dismissed it as just a check engine light ♀️ I honestly can’t remember what that ‘odd’ warning said♀️ I’m not alone in reporting this - I’m almost afraid to drive my car
Safety: The air bags did not deploy. The potential for significant injury to me, nearby pedestrians and people in cars was extremely high. Luckily, I was able to brace myself sufficiently, there were no pedestrians nearby and no one was in any of the cars.
On 10/27/25 as I was slowly pulling into a parking space, my Audi Q5 lurched forward and jumped the curb crashing into a tree. Happened too quickly to apply the brakes. No warning indications at the time of the incident. Car would not start and had to be towed to a repair shop.
Fortunately, I could get out of that car and my body was aching due to the seat belt and airbag explosion. (Driver side bag exploded for sure. I do not remember if the other side bag exploded.)
Airbags did not deploy. Both driver and passenger were admitted to the hospital with injuries.
The air bags did not deploy. The vehicle was towed to a body shop. The contact called audi livermore ([address], livermore, [ZIP]) and informed them of the failure. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was 9,000.
4.since it was very warm, I left the motor running so I'd have air conditioning as I placed the sun screen over the windshield. 5.the sun shade is one piece and takes a lot of time and effort to properly install. 6.when I completed installing the sun shade, I noticed the car was moving backwards at less than 5 mph.
As I was preparing to park at my local grocery store in an assigned space I experienced a sudden unintended acceleration. The front end slammed into a concrete retaining wall, causing major damage to both my vehicle and the retaining wall. The car was practically at a complete stop when this occurred.
