2025 Audi Q5

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.

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.
