I was driving down the interstate when my Warning Transmission Failure light came on. Then another message said you can drive with limited use if vehicle. Seconds later the Warning Transmission Failure light came on again and said drive to your nearest repair shop. Moments later the Warning came on and said safely stop your vehicle. I pulled over on the side of the road and pit my car in park. After doing so the Warning Transmission Failure stayed on and the car no longer would shift into any gears. The car never overheated or stopped running. I had to get the car towed. My car has been in the shop for 3.5 weeks and no one can tell me what's wrong with it.

1 complaint

The passenger side air bag indicator constantly turns off and on in my Audi no matter if there is or is not a passenger in the seat. I took my vehicle to an authorized Audi service center to have the issue checked and they determined the issue to be a failed pods mat based on the error code returned. Upon researching, I’ve discovered that this issue was a safety recall issue with Audi A5 Sportback vehicles in 2020. My vehicle was manufactured during the time of this particular recall and the issue appears to be indicative of this recall. The recall was safety recall code: 74E3.
