The contact owned a 2015 Jeep Cherokee. The contact that while driving at various speeds, the accelerator pedal was depressed but the vehicle hesitated to respond.

Transmission control module and speed control I couldn't exsellerate while driving in traffic and my car would lock up in neutral and wouldn't allow me to turn off the engine and it was flashing all sorts of problems at once, it would also jerk when I shifted the mechanic first told me I needed a battery and then said I needed a flash update and when none of those problems resulted in fixing my car he then said my Transmission control module was bad so now my car is inoperable so I took it to the dealership and I'm waiting for results. When I'm driving on the freeway I sometimes lose speed or my car would shift into neutral and then jerk when I try to put it back in driving and at times it wouldn't start or become difficult to slow down at an intersection or stop light, my husband is disabled so when it jerks it causes him to hit his head on the passenger side window because he has lost …
After driving a vehicle for a few minutes the lights will flash pretty badly, the service transmission light comes on, on the dash and the car enters limp mode, and the fan comes on, you are unable to move the vehicle it will not go forward or backwards. The vehicle runs perfectly smooth until this happens without warning. Additionally, the service air bag light came on, on the dash but if you turn the car off and back on the lights will go away and you can resume activity as usual. The cars lights and horn goes crazy even when you are not in the vehicle or driving it and does not have to be on when it does this. Now the vehicle has a service engine light on and diagnostics have been done and one part has been changed but this did not resolve the issue which was a purge solenoid and the oil filter housing which also did not resolve the issue. …
When I go to put the the vehicle in park and reverse it wants to shift really hard, not really a shift but more of a jerk. It doesn't happen every time but it does 50 percent of the time. There was this one time where i went to go put it in reverse and it wanted to rev more then usual. When it MAINLY shifts hard is when I first turn it on and start moving a couple feet it wants to fall on its face. We haven't had any incidents in it yet but I wanted to see if I could get anything done before any. Me and my boyfriend travel a lot and when we are in traffic it has fallen on its face. There is a gas cap light that keeps coming on and I have replaced my gas cap 2 times.
Service Shifter lights up on the instrument panel as well as the check engine also stop/start not ready. 4x4 not available exhilarates and UN exhilarates all by its own. Shifts hard and jumps hard when I take off at a stop light don't wanna come out of park unless I take my finger and flip up a plastic thing down inside the shifting housing. And the key fobe won't come out of the key switch. No it hasn't been in a crash yet but it's one looking for a place to happen if jeep don't have a recall. Yes my jeep has been confirmed by the Dodge dealership in Lexington Kentucky. They say that it needs a new shifter put in it I'm taking it to the dealership this coming Thursday
Check engine light on 2015 Jeep Cherokee Sport turned on, vehicle "went limp". Pulled over, turned car off, waited, turned car back on. Happened again taking car to dealership. The dealership said "code for trans range sensor p1726. reset trans and test drove. code did not come back". Same thing happened again a week later. Took it to Firestone, code was "TCM P1726-00 Transmission Manage Sensor "C" circuit High. They said it sounded like the Recall Number 16V529000/S55. I took it back to the dealership, they said the recall, despite being for a 2015 Jeep Cherokee didn't apply and noted "Same code P1726 set in TCM. Going to need range sensor and TCM replaced."
While driving my jeep forward or in reverse my jeep launches forward very hard. I have to press on the brake abruptly so that I don't hit anything. Also when accelerating my speedometer shows the numbers increasing but my wheels are barely moving then it kicks forward abruptly. When turning or going over bumps I feel a pop in the steering column and sometimes the dashboard icon with the vehicle & squiggly lines under it appears. I told my dealership but the mechanic just said there is nothing wrong with it even though I know there is.
Hello my jeep got a message of service 4 wheel drive so i brought it to the dealership. the looked at it and it turns out to be a failing PTU. Jeep did a recall and extended warranty on it but they are saying they will not cover the cost of the repair because its the wrong code. I have code C14A797 and they are saying they need code P14A797. This doesnt even make sense its the same exact faulty part but different codes??? Codes they the car company creates?
My vehicle - at random - will switch to traction control, 4x4, and will slow down while driving, and will not allow me to go above 45 mph, with the engine rpm's revved as high as if I'm driving 85 mph. No mechanic has been able to accurately diagnose it, and I continue to pay for different repairs, without getting the problem actually solved.
