2020 Ram 1500 Collision Avoidance Problems

Driving in moderate traffic, truck forward collision warning triggered and emergency braking engaged with no forward risk of collision. Traffic in front was accelerating, not decelerating and no risk of emergency collision existed. Incident did however nearly lead to collision from behind as brakes were slammed on fully to an emergency stop. Wife and I were both in the car and neither of us saw any reason whatsoever for the event to be triggered.

Driving 60 mph down the highway in North Dallas, no vehicles around me in close proximity, went under an overpass, the truck braked severely, no skid but a very abrupt slowing to 10-15 mph, if anyone was behind us, it would have caused a major wreck. Pulled over and turned off the front collision warning system until I could get it reported. The message it flashed on the dash was unknown object encountered. I have not taken it back to the dealer. No police were called because there was no accident, just very scary.

The contact owns a 2020 Ram 1500 Limited. The contact stated that while driving at 20 MPH, the automatic emergency braking system activated without warning. The wheels seized and the vehicle crashed into a guard rail. No air bags were deployed upon impact. The contact later received medical treatment for injuries sustained to both hands and the right leg. There were four other passengers in the vehicle with unknown injuries. No police report was filed. The vehicle was towed to the dealer, where the manufacturer sent an investigator to inspect the vehicle. The investigator found no fault with the computer system. The vehicle was not repaired and remained at the dealer. The failure mileage was approximately 30,000.

I have taken my vehicle to Ram dealer letting them know the Forward Collison Warning (i.e. 'BRAKE' to show in display and brake if I don't) is not working. Both time they said it was working and basically showed me the front sensors setting. I have tried to test this on the road and almost rear ended three cars: 1) speeding up when car in front is at a traffic light, 2) accelerating to 65 mph coming up on a slower car, 3) coming around a curve on a two lane highway with car coming in opposite direction. No warnings at all. My Honda Pilot shows the warnings in each of these cases. So I went back to the dearler and explained that on the Ram forum, https://www.ramforum.com/threads/anyone-else-with-a-fcw-forward-collision-warning-problem.142051/page-3#post-2623613, other drivers have noticed same thing. My RAM is a 2020. I saw where someone with a 2019 has same problem. Also showed the dealer the youtube video, https://www.youtube.com/watch?v=7SE3irp18ts, so they knew what I was talking about. They told me they don't have any way to test FC. I told them I didn't understand how the FCS is not working when the ACC is working perfectly. This was noted as well in the Ram forum. This needs to be fix immediately if it was discovered on 2019 vehicles: 1) before someone is badly injured because the FCS doesn't work, and 2) I paid for this safety feature and should have it.

TL* THE CONTACT OWNS A 2020 RAM 1500. THE CONTACT STATED THAT WHILE ATTEMPTING TO ACTIVATE THE COLLISION AVOIDANCE SYSTEM, THE SYSTEM FAILED TO OPERATE AS DESIGNED. THE CONTACT STATED THAT THERE WAS NO WARNING LIGHT ILLUMINATED. THE VEHICLE WAS TAKEN TO THE LOCAL DEALER CHAMPION CHRYSLER DODGE JEEP RAM, INC.
