Adaptive Cruise Control problems of the 2025 Audi Q5

Regarding the adaptive cruise control, sometimes the system won't engage. The first time this happened a warning popped on the screen saying something about seatbelts. I've learned that the problem can be "fixed" by pulling off the road and turning the car completely off. That includes opening a door to silence the radio. The cruise has always worked afterwards. Sometimes while driving on cruise control, in a straight line, the car brakes abruptly for no apparent reason. Granted we were on the interstate and there was traffic but no reason whatsoever to brake. The cruise control is easily confused on roads with multiple lanes and sharp curves, like on [xxx] between asheville, nc and knoxville, TN. The car will brake abruptly, seemingly sensing a car in front of me but in a different lane. Sometimes when reengaging cruise control the speed goes not to the speed I had set but what it "sees" as the posted speed limit. This caused the car to speed up in a construction zone and slow to a speed below the prevailing speed of traffic around us.

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.

There appears to be a software problem with the car. On the display, there are malfunction messages about the airbags and safety features.

I periodically receive warnings for adaptive light malfunctions, headlight assistant malfunctions, active lane assist malfunctions, traffic sign recognition malfunctions, adaptive cruise assist malfunctions, and high beam assist malfunctions. The Audi dealer confirmed these issues and stated a solution is being worked on but currently not available since it appears to be a software issue. These warnings first appeared within the first 250 miles and has continued to periodically appear. These issues are available for inspection. The malfunctions jeopardize the safety measures which are standard on the car.

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.

I bought the car on September 2, 2025. The car has been in the dealer 5 times. The last one started on December 2, 2025, and still in the dealer as of today (January 8, 2026) no solution has been found. Most of the time is having problem with the technology in the car. I cannot even drive it. It has problem with cameras, traffic sign recognition, adaptive cruise assistant, adaptive light malfunction, headlight assistant malfunction, Audi active lane assistant malfunction, accessibility service malfunction, driver system malfunction (limited vehicle performance), and the list keep on going. I am trying Audi America to buy my car back. I have the car for 4 months and I have use it for approximately 3 weeks (milage as of today 1,529 - several miles done to test the car by the technicians).
