What 397 owners told NHTSA about the 2021 Jeep Grand Cherokee Trackhawk

Crossing 4 way intersection with no cars or animals in site and while accelerating at about 40 mph vehicle came to a shuddering halt in the middle of the road for no reason. My husband and I were both thrown forward whipping our necks back and forth and my collar bone taking a direct hit with the seat belt. There were no sounds to warn us, no lights came on it just slammed its own brakes for no reason. My dealership brought me a loaner and vehicle was towed to them where they are working on getting the issue solved, but I am going to be terrified this will happen again and rightly so.

I was driving 45-55mph,closest vehicle was about 4-5 car links in front on me, driving about same speed-when the breaks locked up. I had not hit the break! On my dash where the mph is located it turned red and said BREAK.It made the jeep pretty well come to a complete stop in a second. The seat belt caught my neck,my son (passages) seat belt caught his belt and hurt his stomach, my son (back seat driver side) hit the drivers seat pretty hard. I have now took my jeep into the dealer. No word yet in there findings. This was scary and could have ended very badly. We was fortunate enough not to have wreaked or worse. I don’t know who or where to contact someone about this issue.
