Owner report 11522924 · 2023-05-19 (May 19, 2023)
At a highway speed of 50 MPH the transmission completely disengaged. I was driving on a busy highway with no shoulder. The vehicle continued to coast until I was forced to stop in an unsafe location. I placed the car in park, then in drive, and it was still disengaged. I needed to turn the car off, turn it on and it drove normally. Before I was able to bring it into Audi it occurred a second time on a bridge. I needed to perform the same steps (park, turn off, turn on) to begin driving again. Audi 'repaired' the vehicle. One month later…

Owner report 11476690 · 2022-07-30 (July 30, 2022)
Today, I was in a protected left turn lane prior to making the turn. When oncoming traffic (4 lanes) cleared, I gently pressed the gas pedal to start the turn, but a red “pre-sense” error triggered and slammed on the brakes. I moved my foot to the brake and then back to the gas, and the error cleared, allowing me to continue the turn. This was dangerous as I could have stopped in front of oncoming traffic or been rear-ended by the car behind me. This is the first time I’ve had pre-sense braking engage, though I’ve gotten error messages while tr…

Owner report 11702177 · 2025-12-01 (December 1, 2025)
The car has traffic sign recognition and uses it for "predictive control" where the vehicle will read traffic signs and adjust the adaptive cruise control setting to based on road signs. It had previously been working well but a software update was recently performed under TSB 2074688/3 on November 6th, 2025 and problems have shown up. Specifically, the system is incorrectly reading signs and sometimes appearing to make signs up out of nowhere. This has resulted in the car slowing down quickly on highways and nearly causing a couple of rear-end…
