Vehicle has been to dealership four times for the same problem. After driving longer than 10-15 minutes turning the Jeep off and trying to restart within 5-10 minutes it won't start. Let it sit for minimum of 20 minutes will start. The relays get very warm but after cooling, the car starts. Dealership has zinged us for a new starter, it didn't need, a new pcm, it didn't need. Testing my own theory 3 consecutive times in one day, drove the vehicle at least 30 minutes. Turned off and attempted to restart (as you would a quick trip to the store) and nothing but waiting each time, car starts after cooling. Picked up the Jeep two days ago from dealership who had it 18 days trying to fix it (3rd time)and the first trip that day resulted in another occurrence of the same problem.
