Adaptive cruise control not working. . . . ,intermitently shutting off. This is coinciding with numerous engine, oil and gas warning lights going off in the Audi mmi system. Lead tech at Audi dealership in norwell MA is telling me that this is a well known issue with the 2025 Audi Q5 needing a software update that will not be available until sometime in the 3rd quarter.
My vehicle has now experienced a serious electrical malfunction a few times, including one again today. Each time, the car suddenly loses power and drops to 40 mph, the steering wheel shakes, and all warning lights come on. This is extremely dangerous and puts my safety—and the safety of others—at risk. The car is brand new and has about 1200 miles. I took the car in previously, and the dealership admitted they do not know how to fix the issue. Despite this, when I called again today after the problem happened, they refused to take the car in. At this point I do not feel safe driving it or having anyone else in the vehicle. This is severely impacting my daily life and mobility. I need immediate action and a resolution to this unsafe situation. I only get run around when I call Audi fletcher jones and my service adviser does not resolve my issue. They don't let me speak to the general manager and they don't give me his email address. Attached are two photos. I have a video which I can submit per your request.
Randomly the mmi screens are blank. This means I have no speedometer, I cannot see my fuel level and there is no Audio, such as blinker indicator.
Check engine light is on almost constantly on my car. It might turn off and stay that way for a couple of days, but always comes on again. Dealership had made two attempts to "fix" it by just clearing the faults. However, according to the service department the reason why check engine light came on was "faults for loss of communication to powertrain electronics and brake electronics" which I think is a real safety concern. After my last trip to the dealership the check engine light came on after just two days of normal driving. There was also a situation when I was unable to shift to park with the risk of rolling along with some other error messages on the dash. I was unable to lock the vehicle because of that and of course there was a risk of it rolling.
Fault p003a00 (turbocharger boost control position sensor). Vehicle suffered a catastrophic power failure (limp mode) on day 2 of ownership. Total loss of acceleration while in traffic. 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.
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.
This vehicle misrecognizes intersections on two lane highways and causes the vehicle to unexpectedly slam on its brakes without warning in anticipation of an intersection that either does not exist or where my vehicle has the entire right way. This behavior has persisted since the date of purchase and has not been corrected at all. Audi has confirmed that the vehicle is operating as designed however, I have personally almost had two major traffic accidents when this system engaged in the process of overtaking a vehicle, slamming the brakes and almost causing a accident where he and I was rear ended. This is not a vehicle. I would let a child learn how to drive in.
Brand new car, needed a major software upgrade, for engine code, no heat , safety system flashing. It’s going back to the dealer today , for faulty gps and limited camera view for speed signs. The car has major software issues.
I am reporting a safety-related defect involving my 2025 Audi vehicle. Shortly after leasing the vehicle in 09/2025, I experienced electrical and system malfunctions while driving, including warning lights, intermittent adaptive cruise control malfunctions, erratic acceleration, sputtering, and sudden braking without warning. These issues occurred during normal driving and raised safety concerns. On 11/03/2025, the vehicle failed to start and required multiple jump starts, displaying multiple system errors including a check engine light and malfunctioning displays. During a brief attempt to drive, the steering wheel began vibrating, additional warnings appeared, and the vehicle behaved as if on rough terrain despite normal pavement. The vehicle was towed to the dealership on 11/04/2025. While there, Audi’s technical assistance center (tac) and engineers were involved, and I was informed that internal technical guidance was issued related to this issue, indicating it may not be isolated. After more than two weeks, I was told the vehicle was repaired. On 11/19/2025, immediately after pickup, it malfunctioned again at highway speed. During lane changes, the vehicle resisted steering input and attempted to keep me in the lane despite signaling, creating a loss-of-control situation that required abrupt correction. A rear crash assist malfunction warning also appeared. I returned the vehicle the same day. Although it may start and run, I do not believe it is safe to operate due to the prior loss-of-control event and continued system instability. I have been asked to drive it again to reproduce the issue, which I do not feel is safe. This may involve a defect in driver assistance and electronic control systems.
Two weeks after purchase, experienced multiple, random driver assistance failures. After attempting to repair issue once unsuccessfully, the dealership was unable to provide a second service appointment for two and a half months. Was explained all 2025 Audis were having issues, so couldn’t get car in any sooner. Before that second scheduled service appointment and while driving in traffic, the brakes failed.
All of my display screens went blank at 108 miles. I had no speedometer, no fuel level gauge, no warning indicators, and no Audio alerts including turn signals. The vehicle was towed to the dealership since it was a safety issue for me to drive. It has been there since November 2025.
The car floods with excess fuel after idling for a short period of time resulting in multiple misfires and violent vibration. The car will not restart and will need to be towed. In traffic jams, the car can fail stranding motorists and creating a very unsafe situation. The problem has been verified by the dealership. Apparently, it is a known issue with the new Audi Q5 and they do not have a viable solution. They said to put the car in neutral and rev the engine to try and burn excess fuel. However, once the misfires start, it’s probably too late. I have pictures of the warning lights and the service reports. The car is 2 weeks old and has been back to the shop twice ( towed once) for a total of 5 days.
