Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“My car's passenger side front seat abruptly developed a sensor failure. The passenger airbag off light is lit, signaling the airbag won't deploy despite a passenger sitting in the seat. This is dangerous. There has been a recall issued in june 2018 on 140k Audi cars with similar problem, my model has yet to be included, and there are likely more cars with similar malfunction.”

“Audi recall 69z4 messed up my passenger airbag and seatbelt warning sign. Had no issue until after the recall, so I called Audi immediately after and they claimed I had to replace some sensor that had 'nothing' to do with the sensor they 'fixed' from the recall. When the car starts the passenger seatbelt warning sign keeps blinking with the airbag light on when there is no passenger. When there is a passenger and the car starts there is no seatbelt warning sign and the passenger airbag is turned off. …”

“The passenger seat airbag sensor is faulty. I see everyone else has the same issue but when I type in my VIN it says it is not recalled? They wanted $1000 to fix it but it isn't my fault and I hope to see them own up to their mistake and fix our airbags. Online it says my vehicle should be covered and fixed for free but when I checked their site 2015 Audi S3 isn't covered, however, on this site, it will say it is but when I type in VIN nothing.”

“Gear Shift Micro Switch This is a documented issue recalled for VW and Audi vehicles between 2015-2019. VW recalled all and still is fixing the issue in cars from those years, yet AUDI decided to just offer an extended warranty to those cars for that specific issue. Who is responsible VW or AUDI. If Audi is owned by VW and the issue is in both types of cars made by them, why aren't AUDI vehicles included to the recall and repair.”

NHTSA complaint #11626453, filed 2024-11

“Passenger seat occupancy sensor srs airbag light warning comes up whether or not there is a seated passenger. Passenger is not being detected and airbag stays off. Happens when stationary or in motion. Vehicle is always giving warning sounds that seat belt is not fastened. Issue tested by dealer. Seems to be common known issue with recent Audi's. Others to have reported same issue.”
