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.

2025 Audi Q5 driver assistance complaints
Page 2 of 2: complaints 11 to 26 of 26, newest first, as owners wrote them.
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.
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.
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.
The ADAS is not working properly. Adaptive cruise control, emergency assist, lane departure, active front assist, distance warning, traffic sign recognition, adaptive light, etc. are all not working. The check engine light is illuminated, the key fob would not open car (not a battery issue) and the seat belt tensioner is not working properly. Those ADAS features are there for a reason and that is to enhance the safety of me, my passengers and other drivers. The key fob allows quick access to my vehicle, which enhances my safety when alone or with others. The seat belt tensioner provides restraint during an accident so neither I nor my passenger will go head first into the windshield, air bags and/or steering wheel/dashboard. The problems have been confirmed with the dealership. Yes, it has been inspected by the dealership. Yes, they first appeared January 2025. My car is currently at the dealership supposedly waiting for a backordered seat belt tensioner. It has been at the dealership for 22 days and I haven't any idea of when I will be getting the vehicle back. I purchased it in October 2025. It has been driven less than 5,000 miles.
The vehicle triggers the braking system when there is nothing in the road, this has happened when turning across traffic, into parking lots, and when just driving on a road. Luckily this has not caused a crash yet but it has a high likelihood of causing a crash if not properly fixed by Audi. Occasionally the sensors stop working and the seatbelts tighten aggressively. This is especially risky because my wife is pregnant and this tightens for no reason around the baby. This has happened many times in the short time I’ve owned this vehicle.
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 recurring safety defect in my 2025 Audi Q5 (VIN: [XXX] ). The vehicle has been in the dealership for approximately 42 non-consecutive days for repeated malfunctions of multiple safety systems.While driving, the vehicle displays warnings and disables the following systems: SOS, Adaptive Cruise Assist, Active Front Assist/Distance Warning, Lane Change Warning, Proactive Occupant Protection, Traffic Sign Recognition, Adaptive Light, Emergency Assist, High-Beam Assistant, Lane Departure Warning, and Distance Warning. These systems intermittently fail and become unavailable, triggering dashboard alerts and warning messages.Despite multiple repair attempts, the same failures continue to reoccur. The dealership has acknowledged the issue and stated that a fix exists; however, they advised that the necessary repair parts or software will not be available for approximately 3–6 months. I was instructed to take the vehicle back and continue driving it until the fix becomes available.I am extremely concerned about operating a vehicle with known unresolved safety defects affecting numerous driver assistance and crash prevention systems. The repeated failure of these systems significantly impacts the safe operation, reliability, and value of the vehicle. I am requesting investigation into this matter and the delay in providing a timely repair. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The audi presense seems to be too sensitive and it is available for inspection. There have been 3 times that I've been at a complete stop in the middle of the intersection waiting for the opposing traffic to stop so I can turn left and suddenly the car brakes, seat belts engage and it scares us. 2 times I had just started to turn left and the car braked (no opposing traffic) and it was so sudden the car behind me almost hit me since they were not expecting me to suddenly brake as I was turning left. The car has been inspected by 2 different dealers and they can not reproduce the issue. No other warnings.
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).
* Primary Component: Forward Collision Avoidance * Secondary Component (if available): Electrical System / Lane Departure Step 3: The Incident Description (Copy & Paste below) > Summary of Safety Defect: > The vehicle is experiencing a critical, recurring failure of the Advanced Driver Assistance System (ADAS). There are two primary life-safety issues: > * Phantom Braking: The vehicle initiates sudden, forceful emergency braking without any external hazard or obstacle present. This rapid, unprovoked deceleration occurs at highway speeds, creating an immediate risk of rear-end collisions. > * Total Warning Failure: The system fails to provide any visual or audible "Pre-Sense" alerts when actual hazards are present. The safety suite is non-functional and fails to warn the driver of oncoming items. > * Context: The vehicle has undergone four repair attempts and has been out of service for over 30 days. As of late December 2025, the manufacturer has been unable to resolve these safety-critical software and sensor malfunctions. >
I moved into a parking spot and pushed the brakes to stop but the car accelerated and hit a tree. However when the police drove the car out of the parking spot the brakes were working properly.
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
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.
While driving home from the dealership on Route 65 at approximately 45 MPH, the vehicle suddenly and forcefully applied the brakes without warning. My husband and I are experiencing symptoms of whiplash including back and neck pain. There were no vehicles, pedestrians, or obstacles nearby that would have triggered this response. This was a scary experience, and I am concerned it could happen again in traffic or at higher speeds. This incident presents a serious safety hazard to me, my passengers, and others on the road. The auto was purchased one week ago. Had it in for service. According to the service summary, the Driver Assist System had a coding error, and a hard reset of the module was performed. Unfortunately, after the braking incident, upon arriving home and restarting the vehicle, the same error message “Initializing Active Front Assist” immediately reappeared. I drove the vehicle for an additional five minutes, and the message remained. This suggests the issue was not resolved and may indicate a deeper fault in the system.
