Test-drive through all gears at low and highway speed — no slipping, shudder or pulling.
Confirm every warning light clears at startup (none should stay on).

Always get an independent pre-purchase inspection from a trusted mechanic.

ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE

I am reporting recurring safety-related defects on my 2018 Audi A4 involving Automatic Emergency Braking, Forward Collision Warning, Audi pre sense/front-collision functionality, and related electrical/driver-assistance reliability. The AEB/forward-collision system has shown two unsafe intermittent behaviors. At times it has failed to activate as expected w…

ELECTRICAL SYSTEM,UNKNOWN OR OTHER,BACK OVER PREVENTION

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 fun…

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 mode…

NHTSA ODI #11693480

UNKNOWN OR OTHER

My car's MMI keeps restarting while driving which affects the rear view camera and while backing up it can restart and go completely blank. I feel this puts my safety at risk while backing up. It also shuts down my bluetooth to my phone which can be a hazard while driving. I have called the dealership but they will not do anything without a large diagn…

NHTSA ODI #11684505

UNKNOWN OR OTHER

The Audi MMI system began to spontaneously restart while driving after owning the car for a couple of years. It would power off and reboot at random intervals. It became more frequent and is both distracting and dangerous as you lose all navigation, and camera function while it reboots not to mention any telephone connection. This happens every couple of …

SUSPENSION

Fortunately no catastrophic failure or accident occurred. At about 40,000k miles the rear spring mounts are significantly corroded and need replacing. This appears to be a galvanic reaction that occurs due to a design flaw which shortens the life of the critical mounts. I’m told one could fail imminently and the other is headed that way. Had this failed …
