Engine shuts off while driving

edited August 2018 in Jeep
My 2012 Jeep Grand Cherokee in July of 2014, apx 60,000 miles, engine started to shut off while the vehicle is in drive and driving. Typically this would happen while breaking or making left hand turns. The only way I knew that the engine was off is that the breaks do not work. Nor does the emergency break or power steering. There are no warning light. The radio and light remain on even with this engine failure. After the vehicle comes to a complete stop, you can place in park to restart. At first I thought maybe the key fab was getting hit and shutting off. Upon contacting the dealer they told me to bring it in. At this point I was scared to drive and the dealer would not tow it in. I called the extended warranty company who said they cannot say if the tow will be covered until they know what wrong with it from the dealer to see if it is a covered item. So I drove it I. South Oak Jeep could not figure put the issue but said they cleaned the throttle blade and reset electric throttle and adaptive memor, road tested for 5 miles and verified okay now. This cost me $125.00. They said it was not covered under the warranty. (Turns out they never called the extended warranty to even see). Which now brings me to April 8,2015. On a busy road that is 55 miles I am coming up to a 4 way stop and my vehicle will not stop. Same issue again. This time I bearly avoided a major collision. Called dealer, they can get me in the next day at 10:00 am. So the day I bring in the vehicle they call at 3:30 to say. They our unable to duplicate the problem. There are no codes. They do see a tech case with regards to this issue with possible fixes. So now they suggested I pay $237.50 for a new fuel pump circuit which may or may not fix the issue. Hmm... The extended warranty will not cover this due to the fact that the dealer is guessing physical evidence. They cannot say this will fix this issue. No kidding my thought exactly. Warranty company said the dealer told them it was a tippin power module junction box in the engine bay that need to be replaced. I opened up a case with Chrysler Jeep. Case #26779075. So this time I have to comply and fix/replace parts that may or may not be broken. Charging me for part changing until we can find out which of many it could be. Chrystler Jeep, South Oak Jeep do not seem too concern that there vehicles just shut off while driving. So I am now putting this put there do when I crash into you the next time it dies we all know who to go after. I am clearing not the only one with this life threating issue.

  • This was happening to me in my 2001 JGC Laredo. It was a crank shaft sensor. No engine codes. 
  • I've had the same issue on my 2011 with the 8-cylinder JGC as well. My local dealer is working with another vehicle as well. It only has happened about 6 times in the last year, but luckily happened to the tech during the first drive of the day. It only happens within the first 3 miles of driving it. Dealer replaced some solenoids (no charge/no help). Then they thought it might be something to do with the push button start. They've removed the button and I have to use the key to start it now....BUT, no problems since then. Not fixed, but now I'm not afraid I'll lose power in a turn (it's happened). It had stalled 3 times in the month prior to trying this. Hope this helps someone else. Please sign on and advise.
  • I also have a 2012 Jeep Grand Cherokee and have had the engine shut off twice during traffic; both were near collisions. Once during right turn and just today with my wife turning left for a U-turn.  This is a extremely dangerous defect which scares the heck out of us.  I’m going to start using the key to start the car and hope it doesn’t happen again.  If anyone has any additional thoughts on what could be causing this, please register and let us know before someone loses a life.  I would hope someone from Jeep could post a solution.  The dealerships are always flying blind until a recall comes out and fixes the problem 

  • I have 2012 jeep grand Cherokee that shuts off while driving. Nearly hit other vehicles every time. The only thing I can do is come to a stop as the power stearing goes out as well. This car is a death trap. No one can help because it doesnt throw any codes after it has happend... now what?

    I have a 2012 Jeep Grand Cherokee Altitude 5.7 Hemi that had the same issues. The Jeep would just stall without warning or any kind of symptoms letting me know something was wrong and it was about to do this. The stalling was random and inconsistent and was always a surprise/scare. It mostly seemed to occur when taking my foot off of the accelerator pedal and coasting before coming to a stop. The engine would stall and I wouldn't even realize it until needing to use the brakes or turn the wheel because everything else functioned fine and worked as it should. I would get the Jeep to a complete stop and either put it in park or neutral and it would fire right back up again without hesitation and drive perfectly normal. There weren't any check engine lights and no codes ever popped up in the computer or on my message board. The jeep would drive perfect and problem free for a month or two and then out of nowhere it would happen again. I figured out that the issue was actually the PCM mounting screws. Not the bolts (there are 3 of them) that hold the PCM to the mounting bracket, but the 4 (one in each corner) torx head screws that hold the PCM faceplate to the protective metal case that the actual circuit board is housed. The 4 little screws were too long and touching the circuit board causing it to short out when there was enough vibration or shift of weight (like coming to a stop or taking a hard turn or a decent bump in the road) and the screw would touch the circuit board shorting everything out and causing the engine to stall! I removed the 4 little T15 screws and put washers on each of them and then screwed them back into place and POOF...….. the issue is now gone! My Grand Cherokee at the time had about 53k miles on the odometer and right now the odometer is at 147k and not one problem with stalling whatsoever. By putting the little washers on each of the 4 screws it caused just enough of a gap that the screws no longer touch the circuit board inside the metal housing of the PCM which stopped it from shorting everything out and causing the Jeep to stall. This may help some of you who are having issues with your GC similar to the issues I was having with mine so I figured I would share. Hope this maybe helps some of you and the headache this issue has caused.

    Gee, how'd you ever figure THAT out? That's a good bit of sleuthing! I wonder if the "wiggle test" would have found that?

    there is a recall on grand Cherokee about the fuel pump relay which is internal in the fuse box. Chrysler has come up with a solution to install an external fuel pump relay. seems to help with the sudden stalls. hope this helps

    I have a 2012 jeep Cherokee and mine shuts off too! This is very dangerous and I too have almost gotten into a accident. I am afraid that I will when I have my 11 month old daughter with me in the car.

    I’ve been successful in popping the Jeep into neutral and hitting push/start button and starts right up.  Pop into drive and you’re off.  Once you hit the button everything comes back
