brand new 2025 jeep grand Cherokee less than 3 weeks old - I just got into an accident last night on the freeway my car began to decelerate and accelerator completely stopped working. I noticed an AEBS alert and engine light on the dash but came close to no other cars for this to have come on. Came to a complete stop and I look down and the car is in park. I was unable to put the car back in drive on the freeway. Put on my hazards and called 911 immediately, knowing how dire the situations was, while trying to find a way to get moving, and watched as I was rear ended by a pickup going full speed.
