Just purchased truck a few days ago. Only 350 miles on it now. On 9-27-21 at approximately 8:50am, I was taking my son to school. I stopped at a stop sign and then proceeded to make a right turn onto the roadway when all of a sudden the engine cut off. Everything else stayed on in the truck. It would not allow me to apply the brakes, start the engine, turn the steering wheel, etc. It traveled across the roadway, into oncoming traffic lane, and then came to a soft stop by itself halfway on the roadway. It activated the electronic brake therefore I had to deactivate the brake, apply brake, turn the shifter to park and then restart the engine, disengage the parking brake again, and shift back into drive in order to drive. All this while in the wrong travel lane. Dealer and FCA has been contacted and could not find the problem.
