What owners report
My vehicle was excluded from Recall 25V20100/90VC; however, in early March 2025, it experienced the exact defect described in that recall: a complete failure of the instrument panel module. I paid $3,737.07 for the repair just weeks before the official recall began in late March 2025. I submitted a reimbursement claim to Audi of America under 49 CFR §573 and §577, including the paid invoice and all relevant documentation. Audi has since denied my claim. I am requesting your help to determine why my VIN was excluded from the known safety defect population. If my vehicle was not included, it suggests the recall may have been under-inclusive.
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 collisions due to the unexpected and erratic braking at highway speeds. The car will be going back to the dealer to be looked at, however this is u
The Virtual Cockpit of the car (electronic screen right in front of the driver that displays speed, etc.) randomly turns off during driving, reboots, and displays an error message "Instrument Cluster Malfunction". A loud tone then chimes. This malfunction, while brief, is a safety issue due to the lack of speed information while driving.
Notice of electronic failure on dash, then car notified me to pull over safely due to the failure after 20 min of driving. Car stopped shifting gears and electronic power steering failed while the vehicle was moving. Difficult to maneuver the car to safety once the Safely Pull Over light came on. 28,680 miles on the vehicle. Dealer stated the problem is the starter generator.
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 it happened again. A service report cited this as a known issue. It created a significant risk to safety considering all events occurred at highway
