ACC automatically canceled without braking causing car to either slow down immediately or speed up unsafely, slippery road light turns on, on dash while driving straight, lunging of the car that feels like tires are spinning and or hesitation.
Despite having the EGR replaced under recall the unit still exploded while driving on wed 4 Mar 2026. Fluids were leaking and had indicated issues with the electric shifter. The local dealerships states the egr cooler needs replaced, coolant tank, DPF and oil change (despite just being done the Saturday before). Refusing to acknowledge any connection to previous recall or associated damages. Contacted FCA customer support and ignored my concerns and said just pay the dealer the $6000+.
While driving shifting gears on its own without my control. Slowed me down on freeway from going 50 mph to 35 mph without me slowing it down as I am driving. I was still pushing gas pedal buy while shift was in normal drive from went from 8 to a 3 without my control so I had to pull over because I could not go any faster at all and was in danger zone on freeway that had up to 70mph driving. Once I parked I turned call completely off and then restarted after a min or so it still did the same thing as I drove causing me to pull over more than 2 times. Very dangerous and was not prepared for something like that on busy and fast place as we all know the freeway/highway is. That could of been a total loss for me and other drivers.
While driving my vehicle on the highway, the steering wheel locked up and it put itself into neutral. The abs system notification and another light was active and my jeep stated my vehicle was going too fast for the gear it was in. The abs breaking system bypassed the nss safety feature in my jeep causing me to go off the road as a I lost all control of the steering in my vehicle. Upon a check by the mechanic, I had faulty wiring in the wiring harness which they cannot replace because the part is no longer made. My jeep is only a 2015. I went off the road because there was poor weather - it was snowing out and my vehicle would not respond to any gear resulting in my turning the vehicle off. My jeep was towed to the dealership for diagnosis. I have not picked up my jeep yet due to the dealership schedule but have attached the communication with them concerning the problems.

The vehicle was taken to the dealer and was diagnosed with transmission failure. The contact asked the dealer to complete the recall repair; however, the dealer refused. The vehicle was not repaired due to the cost. The failure persisted, and the vehicle remained at the residence unrepaired. The manufacturer was not made aware of the issue. The failure mileage was approximately 170,000.
The Traction control light comes on while driving, once that happens it changes the performance of the vehicle it stays in one and it doesn’t allow you to do more then 43 at the most.
On the highway my 2015 Jeep Grand Cherokee Diesel briefly stalled and the check engine light came on. I then lost all power and could only maintain a speed of 45MPH in a 70MPH speed limit highway. I turned on my flashers and could not get off the road due to construction and Jersey barriers for several miles. When I had the opportunity I pulled off the side of the road and called to have my vehicle towed to a service facility. I was informed by the mechanic that scanned my car for trouble codes, a P0336-00 was set in my PCM. The mechanic informed me that I would have to take the vehicle to a Jeep Chrysler dealer. This is apparently a known issue with 2014 to 2018 Jeep Grad Cherokees equipped with the 3.0L diesel engine including RAM 1500s of the same vintage with the same diesel engine installed. The specific problem is that the crank shaft tone wheel is not read by the crankshaft position sensor because of degradation to the tone wheel which is connected to the crankshaft. I have complied with all safety and emission recalls. Related: RC-RW68-20 Safety Recall W68 Transport Canada 2020-371 Loss of Crankshaft Position. Requires the replacement of the Tone wheel. Issued 02/11/2021. RC-RW58-20 Safety Recall W68 Transport Canada 2020-371 Loss of Crankshaft Position. Requires PCM Software update for Loss of Crankshaft Position. In lieu of the Tone Wheel failing, the computer uses the Camshaft Position sensor. This is only designed to not disable the car completely but allow the driver to pull of the road. P0335-00 or P0336-00 wil be set and a check engine light will illuminate. My vehicle was not included in the NTHSA Safety Recall and it should have been.
The contact owns a 2015 Jeep Grand Cherokee Limited. The contact stated that while in a parking space and reversing, the vehicle was then shifted into drive and the high gear message was displayed.

No warning lights illuminated. There were no reported injuries, fire or air bag deployment. A police report was filed. The contact was able to drive the vehicle to her residence. The vehicle was towed to the local dealer where they were unable to duplicate the failure. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 71,535.
My car keeps slipping into neutral, not able to go over forty three miles per hour. Will not go into park or drive at times. Electrical issues. This has happened several times two times on the freeway, with one of them and entering the freeway, almost causing an accident.
The contact owns a 2015 Jeep Grand Cherokee. The contact stated while driving at approximately 30 MPH, the windshield wipers were unintentionally turned on, the infotainment screen darkened, and the vehicle lost automotive power; the vehicle failed to shift to park. The vehicle independently turned off and after several minutes independently started however, there was an abnormal sound coming from the engine compartment. All of the warning lights were intermittently illuminated. The contact stated that she had to call the local Police Department to assist her with exiting the vehicle safely however, no police report was filed. The failure occurred on several different occasions. The contact stated that she sustained emotional distress due to the incident. The vehicle was taken back to the place of residence.

The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was unknown.
Valve lifter failure at 93,000 miles. $2,700 repair. Is apparently a very common problem with the 3.6l Pentastar engine. Adaptive Cruise Control and Forward Collision warning system front sensor failed at 56,000 miles, failed again at 76,000 miles and failed a third time at 95,000 miles. First two failures were replaced under warranty, third failure happened 1 week after warranty expiration from second replacement. Cost is too expensive to repair ($3,000 for new sensor) and requires that safety feature be turned off as sensor will perceive increases in road elevation (hills) as another vehicle and apply the brakes
Car accelerated without warning propelling me across a curb, street, then a second curb. The SUV was stopped upon impact at a concrete building. Fortunately there was no injury to others but the accident caused the car to be totalled by my insurance company. There were no warning lamps, messages or other symptoms of the problem prior to the failure. The airbags did not deploy upon impact,
When setting cruise control to speed limit then pressing brake and then resume the jeep sone times accelerates to a higher speed the. Having to break again. Has been reoccurring nervous when driving and setting cruise or resuming. Have not taken it in as of yet.
We were driving and we heard a chime and nothing showed on the display panel. Then we went thru the displays and saw a message regarding the ACC something about manual something. Then we lost power. Since we were on the highway We turned the truck off and started it again to potentially reset. We drove a couple blocks to exit the highway and lost power again. The we got out of the vehicle and smelled smoke. We peaked under the hood and saw fire. We all got out, grabbed our stuff and then the fire spread and engulfed the truck. Total loss.
The computer/screen died disabling most of the essential controls/functions of the vehicle including: hands free calling, control of the temperature/air flow, park assist/safety options, security features. This issue also disabled the ability to control other functions such as the windshield wipers and drained the battery until it died. The battery had to be recharged and then after that any time I turned the car off I had to unplug the battery so that it wouldn’t be drained.
Cruise Control, O2 SENSOR, Fuel/Propulsion System , BATTERY, If your check engine light is not on when you take it to the service department they say its hard to detect serves needs. Come back when it comes on again. Trouble while driving when using cruise congtrol it excellerate15miles beyond speed set very scary while driving next 30 minutes smell smoke next flames and smoke coming from underneath hood, open door flames and smoke can into jeep. Causing me to hit my head tryng to watch the fire and get out the truck and getting the two kids out the back the we ran then the exploded. The 911 button inside did not work! Now we can't sleep!
The license plate LED lights went out. Pulled over by trooper to get them replaced, as they are a safety concern for troopers to identify the license plate number. After a few trips to a couple auto parts store, I learned that none of them carry lights. One of the parts stores representative said I would need to get in touch with Jeep. Jeep confirmed, that they need to replace the wiring harness and lights for this model year which is 2015. I looked online and it seems to affect model years 2014-2019. Jeep wants to charge nearly 200.00 to fix the issue. If the lights are required for safety concerns and help with backup camera to make it more visible in the dark, then this should be a concern to owners of Jeep Grand Cherokee model. There are no warning lights to let you know the lights are out until you get pulled over and ticketed by the police or you go to get the vehicle inspected and told you need a costly repair. If Jeep knows about this defect, they should be doing a recall for the issue.
Was driving down the road it was raining no other vehicles around BRAKING! came on the screen and the brakes were applied without me doing it. The second time it happened brakes locked up on interstate for a couple seconds then back to normal. If anyone would have been behind us we would have been rear ended. It happened 2 times within an hour. I will be getting it looked at by the dealership as soon as I can.
While in Starbucks drive through, my vehicle suddenly accelerated and hit the vehicle in front of me.

IT WAS FREEZING OUTSIDE, BUT NOT ICY ON THE ROAD. WELL LIT. I WAS NOT IN A RUSH. CAR WAS IN EXCELLENT SHAPE UP UNTIL THEN. I WAS GOING ~10 PMH DOWN THE INSIDE PARKING GARAGE DRIVEWAY. HAD TO PULL TO THE RIGHT DUE TO CAR COMING UP PARTIALLY ON MY SIDE. SCRATCHED THE SIDE WALL. ONCE THAT HAPPENED, THE CAR ACCELERATED OUT OF CONTROL. BRAKES DIDN'T REACT. ONLY WAY TO STOP THE CAR BEFORE RUNNING INTO OTHER CARS OR EVEN PEOPLE WAS STEERING THE CAR INTO THE WALL FRONT ON. THE CAR FINALLY STOPPED, THE WALL BROKE DOWN.

I WAS NOT UNDER THE INFLUENCE OF DRUGS AND DON'T HAVE A SEIZURE DISORDER. WITNESSED EVERY SINGLE SECOND FULLY AWAKE AND AWARE.
A BIG WARNING COMES ON MY DASH BOARD SAYING BRAKES AND AUTOMATICALLY STOPS WHILE DRIVING ON THE HIGHWAY. THIS HAPPENED TWICE. IT IS SCAREY BECAUSE THERE IS NO REASON I NEED TO BRAKE NOR CAN I CONTROL THAT THE CAR IS FORCE BRAKING IT SELF. I HAVE READ 2 OTHER COMPLAINTS ABOUT THIS ISSUE AND BOTH HAVE ENDED IN CRASHING THE VEHICLE DUE TO THE COMPUTER FORCE BRAKING ITSELF IN THE SUV.
