2025 Audi Q5 Problems & Complaints

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.

My car was not operating effectively and was displaying many dash lights. I brought it to the local Audi dealership and they kept it for several days - they did a software update but most of the dash lights stayed on. They did an investigation and diagnostic review and they told me that the passenger seatbelt igniter needs replacement and that i could not safely transport passengers in my vehicle and they would order the part. The seatbelt igniter is a safety component and I am unable to use my vehicle safely/effectively as a family vehicle until this issue is resolved. The dealership has an order with Audi but there is an unexplained parts hold and no one can communicate any updates or ETA to me.

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.

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.

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

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.

The contact owns a 2025 Audi Q5. The contact stated that while driving at undisclosed speeds, the panoramic sunroof glass exploded without impact. The contact pulled over at a pit stop to inspect the vehicle. Despite the failure, the contact resumed normal driving with shards of glass falling from the sunroof. The manufacturer was notified of the failure and agreed to have the vehicle towed to the dealer. The vehicle had not been repaired and remained with the dealer. The failure mileage was approximately 12,000.

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.

After the automatic start/stop system engages, the engine stalls and completely shuts off shortly after the vehicle begins moving again. This occurs after the vehicle restarts and travels only a few feet. When the stall happens, the vehicle loses power and the engine stops functioning while the car is in traffic. This has occurred two separate times: once on a busy highway and once while entering a roundabout. Both incidents created a dangerous situation where the vehicle could not maintain power in active traffic and could have resulted in a crash. A yellow emissions warning light also appeared on the dashboard. The dealer indicated that an intermittent oil pressure sensor code was present but no parts were replaced and no corrective action was taken. The dealer reset the system and stated they could not reproduce the problem. The vehicle is now being returned to me without repair despite the safety risk. An engine stall immediately after the start/stop system restarts the vehicle creates a serious hazard because the vehicle can lose power in the middle of traffic. I believe this issue may be related to the automatic start/stop system or an oil pressure sensor fault affecting engine operation.

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

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.

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).

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.

* 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. >

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.

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.

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.

The contact owns a 2025 Audi Q5. The contact stated while driving at undisclosed speed on three occasions, the contact noticed that there was an abnormal knocking sound coming from the dashboard. The vehicle was taken to the dealer to be diagnosed, but the cause of the failure could not be determined. The vehicle remained at the dealer unrepaired. The manufacturer was not notified of the failure. The failure mileage was approximately 10.

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.

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.
