2018 AUDI A4 Forward Collision Avoidance Warnings Problems

The Audi Pre-sense engaged on 3 occasions going 50+ mph bringing the car to a complete stop when there was nothing in front if it and a car right behind me. I was lucky the car behind me did not collide. If it had been a semi truck and just as close as the car trailing me, they would not have been able to stop in time causing damage or death. The problem could not be confirmed by the Audi dealer who performed a vehicle scan and found no codes and could not reproduced it. I had the Pre-sense shut off. I reported this to the manufacture on 6/17/22. The Pre-sense red warning triangle displayed in the instrument panel as when it was engaging.

The forward collision warning system (Audi PreSense) identified a shadow from an overpass as another car and alerted me to use the brakes. My car did figure out there was not another vehicle before performing an emergency brake. If the car had done an emergency brake I would have surly been rear ended on the highway. This is not the first time forward collision warning has activated due to a shadow on the road. I have not mentioned this to the dealer but have read of this happening to others that own Audi cars that use Audi PreSense. The Audi PreSense installed in my car utilizes the front facing camera only - there is not a forward facing radar system. There has never been a warning that that system is not functioning as intended.
