I purchased a new 2025 Audi Q5 Sportback on 4/13/2026. I brought my car home that day and then had to go to the hospital for surgery so didn't drive my car for two weeks. I get in my car after a couple of weeks and the engine light came on and didn't come off I took it into Audi on May 7th. Audi said I could pick up my car on Monday May 11th and said the car battery was charged and I should be good. I brought my car home and then didn't drive it again for a week. I got in my car again and the engine light came on again. I called Audi on the Thursday before Memorial day and was told I needed to bring this back in. I took it in on Tuesday, and was told this code is a known issue and Audi is putting a fix in place to update the modules. They provided me the attached from Audi. If this is a known issue, I feel this should have been provided to me about this before buying the car. I was also told to continue to drive the car and with the light on. How dangerous is that to drive a car with the engine light and ignore it. If something is seriously wrong, I won't know cause I am told to ignore. I would like to know how to return this car as a lemon has this was a known issue and they don't know when the fix will be in place. I am asking for assistance on how to proceed with Audi. I have read several reviews on line with others that have experienced the same issues over a year ago. Thank you !

I bought this car in 12/2025. After putting approximately 60 miles on the car, the onboard computer would not save the inputted data. Took back to dealership and update performed. Upon returning the car for this work, the adaptive cruise control would shut itself off on the way to the dealer. They could not replicate this issue. Since having the car for about 6 months the car has been in to the dealer approximately 7 times all for different warning lights including having the module needing to be replaced that controlled the A/C. The most recent problem is the vehicle locking up its brakes and rapidly fastening down on the seatbelt while driving stating a red danger message that flashes on the informatic screen and then disappears but will not show up on the MMI screen. This has happened twice in the last 10 days. Upon the first visit I was told that Audi has been having a lot of problems with the 2025 Q5 because of the computer. The car is currently back in the shop for continued safety components selectively turning off on their own and the car slamming on its brakes when there is no adverse event. There is supposed to be a patch coming out in Quarter 3 2026, but an actual update isn't set until 04/2027 per Audi service. I have stressed how not having these functions working correctly has made the car a hazard to drive as I never know when it will act appropriately. Also the lane departure feature does not always work appropriately and will try to hold in a improper travel and will jerk the wheel. I have completely turned that function off since it has tried to turn me into on coming traffic.

I had adaptive cruise control on in moderately flowing traffic on the highway. Without warning the adaptive cruise control on it's own turned off/disengaged and slammed on the brakes. I had not changed lanes nor had anyone moved in front of me. The weather was clear. My safety and the safety of those behind me was put at risk. I've taken the vehicle to the dealer and they have not been able to reproduce the issue yet. They inspected the vehicle and took it for an initial 7 mile test drive, said they didn't find any problems and tried to return the car. There were no warning lamps or messages before or after the incident. I didn't notice any when it happened as I was focused on trying to avoid an accident. Prior to the incident the adaptive cruise control has turned off multiple times with the message " Adaptive cruise assist: currently not available" for no apparent reason, but this is the first time hard breaking was applied.

The lane keeping assistance system was engaged as we were traveling at approximately 55 mph and started around a right hand curve. The system aggressively jerked the car to the left and with the wheels on the rumble strip associated with the center double yellow lines. There was traffic flowing the opposite direction and we would have been head to head with an oncoming truck had the driver not stopped the car. The car has been to the dealer, they can not reproduce any issues with the system and have asked that video be taken the next time this happens which is not feasible nor safe. I have not driven with the lane keeping assistance on since this incident, this was not the first time that I had issues with it trying to turn the car out of a lane, and I do not feel comfortable with it engaged any longer. There were no warning lights or messages.

The seat belts are sometimes locked when they should not be. I understand that the seat belts are designed to lock when the vehicle stops quickly, preventing the driver from leaning forward. However, sometimes my seat belts are locked while I am driving and have not made a fast stop. For example, several times the seat belts have been locked when I get to a drive up window or kiosk, and I cannot lean forward to get a parking lot ticket or interact with the kiosk. The seatbelts have also been locked when I am stopped at an intersection. The locked seat belts prevent me from leaning forward to look for vehicles at the intersection or to see around my passenger. I have to pull on the seatbelt a few times and release to get the belt to unlock and let me lean forward.

The windshield wipers in the vehicle do not turn on automatically until the vehicle is in drive and moving forward. If I want to see in the rain so that I can leave a parking spot, I have to use the windshield wiper control lever to manually wipe the windshield. It only wipes once when the lever is depressed. This is inadequate in heavy rain. The wipers do not go on when parked even when the wiper lever has them on. I thought my wipers were working incorrectly, but when I took it in for service, the manufacturer told that is how they are designed. It is unsafe for the windshield wipers to stop when the car is parked. Drivers need the rain wiped away before driving, not just after. In addition, the wipers do not actuate when driving in reverse, such as when backing out of a parking spot.
