Most Recent Complaints
The contact owned a 2018 Audi A4. The contact stated that while driving at an undisclosed speed, there was fluid leaking from the front of the vehicle. No warning lights were illuminated. The contact also stated that while the vehicle was parked, there was a puddle of fluid leaking from the front of the vehicle. The vehicle was taken to an independent mechanic, where it was diagnosed and it was determined that the water pump had failed and needed to be replaced. The vehicle was not repaired. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 92,000.
This problem is extremely sporadic, and often remedies itself after car shut down, and sometimes require that the car sit for a period of time. I estimate the following issue happens ~1 time a month, or estimated 5% of the time. Weather (temperature specifically) does not appear to impact occurance. When reversing, at times the back up camera does not function properly. During these times, the parking sensors appear to work, but it's unclear if the emergency reverse automatic braking system is working. The backup camera issues present themselves in several different ways and are described below. 1) Scrolling view (think of an old time movie, where the image "scrolling" through the screen 2) Black, but not completely black, includes what appears to be interference (sometimes white pixels flash randomly throughout the screen) 3) Off color (almost like a color inversion), darks appear light, light colors appear dark, similar to how things when developing film in a dark room 4) Similar to #1 but instead it freezes, halfway through a scroll. Often times the picture is split, with the bottom on the top, and the top on the bottom, and a clear black line in the middle Opening and closing the trunk, tapping the camera, turning the parking sensor (and camera) off and on do not solve the issue when it happens. Neither does changing from R to P on the transmission lever. Issue always requires a restart, rarely does an immediate restart fix the issue. The tracking lines are also distorted when this happens. When not malfunctioning, camera system works perfectly. Recently, I came across NHTSA ID: 25V900000 which almost exactly describes my issues but my car is not included. I did recently ask the Dealer to look into it during my 40,000 mile service. They stated that no codes were in the system and they could further troubleshoot but the intermittent nature would likely result in no findings unless the issue is present on site.

My screen turns on and off consistently not allowing me to use my backup camera. Causing a small collision while backing up when the camera turned off unexpectedly. Additionally when it’s off it will auto break when I’m not close enough to hitting and it’s loud and yanked me. This has been an issue for some time and I’m seeing a significant amount of my models have this issue and it’s not safe.
