Five problems related to engine stall have been reported for the 2012 Jeep Wrangler. The most recently reported issues are listed below.
Beginning of Feb. , lost power on freeway. Went from 65 to 40 mph and could not accelerate. Engine and traction lights came on. Exited the fwy and drove to dealer where I was turned away due to high volume. Left my Jeep at the dealer the following day with this issue and to correct campaign #v51 recall. The engine light wasn't lit anymore and dealer couldn't find anything wrong with it so I picked it up. Couple of weeks later, I failed the smog check I need to register my Jeep, and an engine code showed up, p0394. I took it to other places where the same code showed up and was recommended to take it back to the dealer. Going downhill, my father experienced the same while driving my Jeep. Beginning of March, omw to the dealer on the fwy, I lost power again and the engine and traction lights came on. I showed the dashboard to the service advisor, explained the continued problem and the code showing up. I left my Jeep there for several days because they couldn't reproduce the problem and didn't know what was causing it. The code was cleared when I picked it up. The following day, as I was making a right turn into a parking lot, the engine stalled. I used gravity to partly move back down as there was another car driving into the lot. I put it on "park" and I was able to restart the car. No engine light this time. This morning I lost power driving to the first stop on my street (stop on my side only). I had already entered the t-intersection but could not accelerate to turn left. I put it in "park" then back to "drive" and accelerated normally. There were no cars around because of the corona virus, but I would have been hit on the driver's side if a coming vehicle (who has the right-a-way), decided not to slow down.
While approaching a stop-light on several occasions (but not on every occasion), the 3. 6 liter pentastar engine in my 2012 Jeep Wrangler sport has stalled, which causes immediate & complete loss of power-steering & hydraulic brake-power. To restart the engine, I must shift into neutral or park. To put the vehicle back into drive after restarting, the vehicle's computer requires me to come to a complete stop. This is dangerous and disruptive when I'm in traffic and there is not a requirement to come to a complete stop (for instance when the red light turns green while I'm slowing). Furthermore, the engine frequently stalls at low speed in parking lots and also when the vehicle is completely stopped.
This has happened twice, the first time I was on a city street and while driving approximately 40 miles an hour the engine stalled and I lost the power steering and breaking. The vehicle was still moving, I put the vehicle in neutral and tried to restart the vehicle. It would not start. We pulled over and called the dealership. While I was on the phone with them, about 10 minutes later, trying to get it in a position for the wrecker, my wife tried to start it and it restarted. We drove it home and had a wrecker come get it because we were afraid to drive it 20 minutes to the dealership. They felt like is was the fuel pump and replaced it. I picked it up and it drove fine for a few weeks and did the exact same thing except this time I was on the interstate driving about 60 miles an hour and fortunately I was in the inside lane and pulled over. Tried to restart it and after waiting 10 to 15 minutes it restarted again. I drove it to the dealership where it is right now with them trying to determine the problem.
We have had multiple times where the engine will stall at idling or low rpm's. We have had the vehicle at the dealer 4 times now and of course they cannot diagnose the problem. Yesterday, they car would simply not start at all and it only has 28,000 miles.
