2015 jeep grand cherokees going into neutral on occasion while driving at speeds above 45mph. I brought my truck to jeep and expressed my concern about this safety issue and my safety. I was informed by jeep there is nothing wrong with my jeep since no codes are showing. I asked to speak to the mechanic and the mechanic told me that there is not one problem with that jeep and the 8 gear transmission is the most stable. He then said you probably put the jeep in neutral while driving. I was completely frustrated with his response and said to him, do you think I would put my jeep in neutral while driving 55mph and risk my life and possibly someone elses? I left the dealership very upset as you can imagine. A few days later it happened again and I contacted the jeep dealer to let them know the issue. Never heard back from them. I was also given the email of my service manager. I sent him a video of what happened after the car went into neutral. I also sent him links that I found online about other jeep owners complaining of their jeep going into neutral while driving. I have not heard back from the dealership yet. My guess, jeep is trying to hide this known issue. When the jeep goes into neutral the check engine light goes on and you cannot put car back in drive you have to coast to side of road. Try doing that on a 3 lane highway. Very very dangerous! Please look into this issue . I bought the car from carmax and carmax said I could have jeep look into issue. The jeep repair center reports there is no issue nor have they heard of any issue like this. If you google jeep goes into neutral while driving there are many threads about such incidents. I need help please. Upload link is not working but I have a copy of the invoice they have given me. [XXX] h INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The car will shift into neutral and become undrivable. Had car towed and they say the part is a transmission control module/valve body #R8259301AC. They say this is a common problem for this model and have had many complaints of same issue. It has been 3 months and the part is not available. This seems to be a very serious and common safety issue.

The transmission fails and defaults to 3rd or 4th gear when downshifting or hitting a pothole. The vehicle then has to limp to a service center for evaluation and repair. At such low speeds during the limp for service, the highway driver is at significant risk or accident

trying to shift from drive to park, will only go to reverse. Must release shifter and push to park again for it to shift to park

Jeep issued a recall almost a year and a half ago, and have taken no action

Transmission failed when I was merging on a highway. Had it replaced and still doesn’t seem normal. This is the electronic shift and apparently has nonstop issues with the 2015 model. Will probably need replaced again before warranty is up and it was done at a jeep dealership.

I’ve recently noticed when leaving my driveway my 2015 jeep grand Cherokee shifts hard / feels as if the transmission is slipping. Today out of now where my vehicle starts slowing down and the rpm is getting higher . I luckily was able to get to the side of the highway to pull over with 3 children in the car . I cut the vehicle off opened and closed the door cranked it and it drove as normal until I was a couple of miles away from home when this happened again . I could not go over 40 mph and the vehicle wasn’t shifting it just sounded like it was reving up . I’ve also been smelling a burning smell inside of the vehicle that smelled like burnt rubber / burning wires. The smell is worse when cutting on the seat warmers . When putting the vehicle in park it sometimes takes a few seconds before the vehicle realizes it’s in park . My headlights at night also appear to look like they are smoking or has a certain smell to them when you get up close

While driving my car, it will randomly shift into neutral. The engine will almost shut off while the battery will remain on. I get a message on the dash telling me to shift into gear but can only shift into park. After shifting into park, I have to turn my car off, and back on before I can shift into drive. I have had multiple parts replaced on my car to fix the issue but it is still happening. I find the car shifts to neutral when going over 55 MPH and then I lose all power.
