NHTSA Complaint #11538385 — 2014 JEEP GRAND CHEROKEE

My JGC 2014. I was on a 5 lane interstate in the far left lane when my car started decelerating at a speed of 64mph. As I was merging into the left emergency lane it switched into neutral gear. I then proceeded to stop and put the Jeep into park and turn it off. Prior to this incident my check engine light had just illuminated a month prior and I ran a diagnostic computer test and it returned stating it was an EVAP problem. I haven’t had any systems. So I was waiting on my first check to get it taking care of (meaning no gas smell in the cabin, no fuel leaks under vehicle, no bad gas mileage). So the police came to my rescue and helped me pull the emergency neutral pull in the middle console in order to get it off closer to the median so I wouldn’t get hit until I could get a tow. Well it wouldn’t turn over again. It sounded like I had a fuel pump problem but when I went to turn it on but not over I heard my fuel pump cut on. So no problems there! So my battery started running low in voltage so I charged it with a battery pack and it got around 13 v and I unplugged it . It’s a 14 v battery. Well I got my vehicle turned in the off position the emergency neutral gear unlocked and then my windshield wipers started and the car was not on . I heard clicking in the fuse part under the hood so I found that fuse and pulled it. I think took a fuse checker and checked every fuse in my box they all had fire. On my dash it started saying system brake suspension and the check engine light was off. So I checked it with the computer diagnostic tester and it said a code of all U’s which were the ECU and the TCM and the gear shifter which was the only P.O. code. So we took my gear shift off and cleaned it and hooked it back up. It was nasty. And it would slap again but not show on my dashboard. So I reset my battery and nothing. I am so upset about this. I’ve worked on every vehicle I’ve owned and this is mind boggling. Everything is up to date and seems fine
