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.
