| Engine And Engine Cooling problems |
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 !.

Manufacturer admits it is a 'known software issue' with no current fix, creating an extreme collision risk for the driver. " vehicle is at dealership since Feb 4th, 2026.
The air bag keeps showing it's not working and that's it's turned off, there's a driving system malfunction, and warning lamp flashing emissions-related fault malfunction are not working. It is a brand-new car and after 2 months, all the malfunction lights keep showing so we went to the Audi dealership and they said they have ordered the parts from germany, but it has almost been 2 months, and they still don't know when it will arrive.
On December 22nd I got into the vehicle and a few errors popped up which consisted of “loose wheel warning malfunction” “brakes: limited functionality drive with causation” “active front assist and emergency assist unavailable”. I called the nearest dealer and was told it’s ok to drive it’s just a software glitch and if I don’t feel comfortable driving I should take it to the dealer and come back tomorrow for a loaner since service was closed already. So I proceeded to drive home, about 10 minutes into the drive a warning for the coolant came up so I pulled off into a parking lot and as I went to park another warning came up saying coolant too high turn off vehicle and as I was approaching the parking spot the car started to overheat and smoke. This is a brand new car with barely 1000 miles on it.
When attempting to accelerate rapidly (I. E. Passing gear) the engine immediately begins to lose power. Audi dealer investigated and determined it was “turbo lag”. This situation happened multiple times at different speeds. When trying to accelerate to pass another vehicle or to merge onto a freeway are the scariest and most dangerous instances. Taking your foot off the accelerator does allow the engine to regain speed. The salesman that we had experienced this on a test ride with me. In reading previous turbo problems with Audi/ Volkswagen vehicles, I’m concerned that this may become a safety issue. This also occurred with the loaner vehicle they gave me which was the same year and model.
