The car's overall electronic reliability and safety are huge areas of concern. Rearview camera and sensors do not always work. Sometimes it will operate while car is in motion but it will black out which ultimately impairs the driver's ability to reverse and avoid any objects and pedestrians. This is potentially dangerous in high-foot traffic area like shopping mall. In addition, the car's lane assistance mechanism is not accurate at times and could have caused accidents several times. For example, the sensor sometimes will mis-detect the lanes and wrongly drift the car out of lanes, almost causing collision with oncoming cars or adjacent cars. Moreover, the Audi sensor which detects object and brakes for the driver doesn't work too well. For instance, when making a left turn at an intersection, it will mis-calculate the oncoming traffic and will brake and stall the car in the middle of intersection. Also, the Audi sensor wrongly detects the object around the car such as elevated sidewalk curbs or fire hydrants and it randomly auto-slam the brakes even while the car is moving at 30-40mph. The car was in the dealership repair shop at least 5 times to attempt to fix the issue. The dealership replaced the "mod box" twice, which seem to fix most of the sensor related issues but issues still arise and I am skeptical and afraid of driving this car.

During a drive on an interstate highway in Tennessee ON12/27/19, the sunroof suddenly exploded. Speed was approximately 75-80 mph on a cloudy day with the temperature in the low 60's F. without any prior indications, there was a loud boom. A section of the sunroof approx 18' in diameter separated from the window and blew backwards onto the road. Smaller shards of glass fell inward onto the sun shade inside the car.

My car has a "top view" rear camera system to aid in reversing. This system fails and is in an unpredictable state on the screen every time I reverse, not showing the view around my car. This is distracting, and leads to problems in trying to switch my top-view camera on (it requires a complex series of 8 button presses while in reverse!) while backing up. I have nearly hit objects and pedestrians due to this safety defect, and it diminishes my ability to safely operate my vehicle when it is reversing. This same defect affects all Audi models with this option sold in cy 2017 and 2018 (including A4, S4, A5, S5, Q5, and Q7). I complained about this safety defect to my dealer on Sept 17, 2017. Audi has acknowledged this defect, and claims it has a fix, but has refused to distribute the fix to existing vehicles for 6+ months. In the time it has known about this issue, Audi misrepresented the safety features of their new vehicles sold in the us, and continued to sell vehicles with this expensive safety option knowing that the system does not work properly -- and, in fact, is so distracting as to reduce safety while reversing instead of enhancing it.
