The Forward Collision Warning in my GV80 activated unnecessarily, which resulted in the car to break without need / warning, this resulted in the GV80 being hit from behind, the GV80 was pushed forward into another vehicle. The vehicle is unsafe for driving and has remained parked. The Forward Collision Warning activated when it was not needed and caused a rear-end accident which was quite impactful since we were not expecting a collision. The GV80 was inspected by an independent service and could not be proved to be at fault. It was deemed to "operate as designed" in spite of our experience and now even though there is damage to one of the front end sensors from the accident. The dealership claimed the GV80 needs $8000 worth of repairs as a result of the rear end incident. I did experience unnecessary collision alerts a week before the collision, when I realized this was faulty, I called the dealership and they explained that there was a setting that was at fault that I NEEDED TO CORRECT in the Settings AND, that they had been receiving others reports of the same problem "three times already today." This setting needed to be reset upon each time I started the car and they explained I also needed to wipe clean all sensors before driving in inclement weather. I experienced 3 more unnecessary Collision Breaking incidents in a single 2 mile driving range and dropped the car off at the dealership as I felt very unsafe to continue operating the GV80.
