NHTSA Complaint #11423785 — 2021 RAM 1500

My vehicle's engine stalls (turns off) while driving at slow speeds. After stalling the transmission tries to put itself in park and the electronic E-brake is automatically applied causing the truck to grind and stop abruptly. This is a safety concern because the vehicle automatically and abruptly stops itself not providing an opportunity to safety move out of traffic. There is also high risk and concern of someone behind the vehicle colliding due to the abrupt stop. The vehicle has been brought to an authorized dealer with no codes or ability to duplicate the problem. No warming lights, messages, codes, or symptoms prior to or after it happening. The vehicle is brand new, happened twice with less than 4,000 miles on it.
