2018 Jeep Grand Cherokee Forward collision avoidance Problems

“After starting my car I went in my house to get something. My car slipped into reverse and rolled down my lawn across a busy street and hit a tree. The emergency braking system did not engage. I was able to drive the car back to where it was parked. I then tested to see if I could have accidentally put the car in reverse when I got out it. It began to roll in reverse and I wasn't touching the gas. I could not have gotten of the car if were in reverse because it would have been rolling. Apparently when the car is in a parked position it can slip into reverse.”

“While using the acc function and setting forward distance at any length the problem is that when the car in front of you slows, stops,,or turns my vehicle will brake on its own. However, while braking during the mentioned operation the big problem is that the brake lights do not illuminate. I have had several close calls with someone nearly running into the back of my vehicle during the use of the adaptive cruise control (acc). This can be extremely dangerous if you are now fully aware of this problem. This should have been addressed during the acc hazardous examination phase. …”

“Driving the auto and applied the brakes at a red light and the brakes only partially engaged and the auto went through the red light. Drove up to the next light as the car was just about to stop it accelerated forward into the truck in front of me. There is a safety feature called forward collision warning which should apply the brakes and did not work (instead of braking with the Jeep safety feature the auto accelerated). The dealer repaired the damage paid by my insurance company but could not tell me why this happened or provide assurance that it would not happen again. …”
