2018 Dodge Durango engine problems

I have 3 major issues. 1 while driving the entire center console electrical system has locked completely up, turning the air off and not allowing any change to the system until the vehicle is pulled over and shut off, continuing with electrical 2x's I've shut the car off and the radio would not turn off, until the battery was disconnected which reset the entire system. My second issue is when starting the vehicle there is almost a grinding noise associated with the start up.

While drive my 2018 dodge durango on the fwy around 65+ the engine just turn off. With kids in the car we were stuck in the slow lane of the fwy unable to move the car. I tried restarting it with no luck. The car still had power(lights were on). The car wouldn't go into neutral .. The car had to be pulled off the road by a tow truck. After about an hour( car was towed) when we got it home we tried again to start the car it started! No check light came on during anytime. A very scary experience.
