The passenger doors fail to open from the outside. The only way to access them is through the driver's door and to use the inside door handles. The dealer is aware of the issue and it was caused by a software update and Audi/VW have no confirmed fix for it. The cruise control does not always operate and gives an erroneous error stating "door open." The dealer has confirmed this error and states there is no repair available. The issue was caused by a software update and Audi has no confirmed fix at the moment. The trunk will not always latch. When closing the trunk goes to the first latch but then fails to fully close. The dealer has made multiple repair attempts and the issue still exists.

Jan 29, 2026Electrical system

The car started with charging issues, Audi said they performed an update that was supposed to fix the problems however they did not complete the update like stated. . The car on 2 occasions while driving MMI screen went blank almost caused me to crash. There was no indication or warnings I took it in again where it’s still at. . The vehicle has been in service several times without being repaired. The charging issue has been on going and does not allow charging or disconnects. on several occasions the car driver assist like lane change braking have gone off without warning.even after saving my preference due to it not saving preference. I have called their support we have tried reinstalling the app. I have been told each time at the Audi service it’s something different. Currently where it’s being serviced again it’s now the charging port. And the battery gets to hot and the previous Audi service didn’t complete the update.

Oct 1, 2025Electrical systemAirbagsBody & structure

While driving slowly through a shopping mall parking lot with my wife and [XXX] son onboard, the vehicle suddenly malfunctioned. The central locking system cycled repeatedly, and a warning briefly appeared mentioning a steering/light malfunction. Immediately afterward, the emergency release cables for all four doors deployed externally as if the car had been in a crash, even though no collision occurred. At the Audi dealership (Audi Sugar Land, TX), technicians confirmed by diagnostic scan that: The ABS control module stored a fault for “invalid data.” That invalid data was relayed to the airbag module, which falsely triggered a “crash response active” condition. All four door modules stored crash response faults and deployed the emergency release cables. The issue was confirmed, faults were cleared, but no parts were replaced. This false crash response put my family at risk because it activated emergency safety mechanisms without cause. My concern is that if invalid data can trigger a false crash event, it could also trigger other systems, such as airbags, leading to potential injury. The incident occurred with approximately 1,100 miles on the vehicle, one week after purchase, and immediately following the first 100% charge. The dealer documented the event and consulted Audi Technical Assistance, who authorized release of the vehicle after clearing the codes. This is a serious safety defect because critical systems activated without a real crash, creating unnecessary risk for occupants. The vehicle is available for inspection upon request.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2025 Audi A6 Sedan verdict →
