Traveling at around 55 MPH, slowed down for a stop light. Dash started flashing and beeping and stated ‘shift to park then shift to desired gear.’ Could not accelerate, had to put in park then back in drive to keep moving. No check engine light. 2 dealerships cannot fix because there’s no code. Seems to be a common occurrence on Jeep forums. Afraid this will happen again on the interstate and I will get rear ended or not be able to get off the road. Major safety concern!
