2018 JEEP GRAND CHEROKEE Complaints

I Purchased my my vehicle from a dealer approximately two and a half months ago. While driving the transmission of the vehicle gave out. The car rpm shot up to seven thousand and only goes 30 mph. My safety was in jeopardy because the vehicle lowed down rapidly and I had to maneuver to the side of the road in order not to be struck from the rear. I had taken it to get inspected by AAMCO and was informed that the transmission failed.

I have noticed the upper edge on my radio screen appears to the bubbling or separating from itself. It has recently become worse and causes "touches" on the screen. It makes calls and ends calls, switches the screen on and off, changes heating settings, disconnects devices, changes or cancels navigation. It makes it very difficult to drive as I cannot turn the screen off.

The car keeps saying the turn signals are out when they all function properly. The car is equipped with the LED factory headlight systems. When it thinks the bulb is out it makes everything flash or turn off so other drivers can’t see your signal. Several other users are also reporting issues online. Dealer says the only way to fix is an entirely new head light assembly at $1300 since the turn signal bulbs are built into the headlight and should be a lifetime part.

I own a 2018 Jeep Grand Cherokee Overland. On December 5, 2025, the vehicle received a transmission fluid exchange service at a Jeep dealership. Prior to this service, the transmission operated normally with no hesitation, harsh shifts, or warning lights. Within a few days after the service, I began noticing delayed engagement and hesitation during shifts. On December 14, 2025, while driving at highway speed, the transmission suddenly shifted harshly with a rapid increase in engine RPM followed by a hard engagement. Later the same day, when stopped at a traffic light, the vehicle hesitated to move forward, revved abnormally, then engaged abruptly. A check engine light illuminated at that time. The vehicle behavior was unpredictable and created a safety concern while driving in traffic, particularly during acceleration from a stop and at highway speeds. The vehicle was driven directly to the servicing dealership and is currently available for inspection. The issue began only after the transmission service was performed. The transmission had no prior symptoms before the service. Warning indicators: Check engine light illuminated on December 14, 2025 after the transmission exhibited harsh shifting and hesitation. Inspection status: The vehicle is currently at the dealership that performed the transmission service for diagnosis.

The contact owns a 2018 Jeep Grand Cherokee. The contact stated that the infotainment screen was significantly delaminated, causing unintended screen activation, preventing the driver from activating some vehicle safety functions as needed. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was notified of the failure and advised the contact to purchase a new screen because the vehicle was out of warranty. The failure mileage was approximately 80,000.

Transmission line has worn a hole from the location it sits under the jeep. The metal hose now has a flat spot. This is because its rubbing on the metal plate below it. I attached photos. I do have a video of what we are seeing and how it’s happening. Yes, it was taken to a dealership for proper diagnosis. Part is unavailable, because of a common issue. No dealership’s are willing to sell the part. It just stated leaking drives fine for now.

8/2023 one rear seat belt would no longer retract. The problem was reproduced by the service center and they replaced the rear seat belt. 10/2025 the same rear seat belt would no longer retract and 11/2025 the other rear seat belt would no longer retract. Brought into Jeep dealer and they verified there are no obstructions affecting the seat belt and they are no operating as intended. They replaced both rear seat belts in 12/2025.

I purchased my Jeep in 2023 and have consistently stayed up to date on all required maintenance. I had no issues with the vehicle until recently, when the check engine light and the start/stop warning appeared out of nowhere. After inspection, the mechanic determined that the entire engine needs to be replaced due to severe coolant leakage. My vehicle has now been in the repair shop for over three months because the engine is on national backorder. I contacted the dealership, but they dismissed my concerns and told me that once the car is purchased, it’s no longer their responsibility. I then reached out to the manufacturer requesting a goodwill resolution, given the unreasonable repair delay and the national backorder of such a critical component. Lemon law mileage limits do not apply to goodwill assistance, trade-in support, or corporate escalations. Despite this, the manufacturer has refused to provide any explanation or documentation for why they cannot assist and it has been three months with no progress. There were no warnings or indicators that something was failing internally, and my mechanic confirmed there was absolutely nothing I could have done to prevent this. I’ve also seen numerous reports of this same issue affecting my specific make and model. Stellantis needs to take accountability. It is completely unfair that I am left without reliable transportation for months over an issue that was entirely out of my control.

My brake light light up, check engine light comes on and my Stability Control system does not work. My car won't electric start as the check engine light is illuminated. I took the vehicle to the dealership and they could not help me as there is no fix in place.
