2018 JEEP GRAND CHEROKEE Complaints

Intermittent extended crank on cold starts and developed a misfire in cylinder 3 and the developed a misfire and coolant leak in cylinder 1. The dealer told me it needs a new engine due to internal engine failure. Codes p0303 and p0300. Engine only has 62,000 on it.

The screen in my 2018 Jeep Grand Cherokee which controls everything (radio, navigation, climate controls, etc.) is delaminating. This causes the screens to constantly change and override all driver selections. This is a significant safety concern and has become extremely distracting while driving. I am surprised that this has not been a safety recall, as there have been many class action investigations. This is a known manufacturing issue especially in the 2018 models.

I was driving down the interstate and heard a very loud pop and got smacked in the back of the head. Later inspection seems that plastic ears connected to the foam portion of my headrest broke off both sides of a horizontal pin they were connected to

The radio touch screen is delaminating causing the radio and its other features to change without warning creating a distraction for the driver. Navagation destination changes loosing route information causing the driver to slow down or stop to try to return to the selected route information. Phone calls are disconnected and the phone then indiscriminately dials a new number from the contact list. You hang up that call and the screen redials the number. This basically negates the functionality of the hands-free feature. This creates serious safety issues when the unit overrides driver choices, as it is distracting because it requires the driver to correct the changes brought on by the malfunctioning screen.

Touch screen started randomly changing radio stations, map kept popping up and it would randomly change inputs such as AM, FM, Sirius, etc.. Other pop up windows would appear such as updating clock, which it had already updated on its own and other window messages as well. Has happened 4 times.

Screen Delamination - Ghost Screen Screen randomly clicks all over. Makes ding sound. Changes navigation, songs, makes calls. Extremely dangerous

The vehicle was later able to be restarted and taken to the dealer, where it was diagnosed with a warped head gasket and an overheated radiator.

At 47,000k miles with all maintenance being done at correct intervals. From one day to the next, check engine light came on with error code p0303; Code P0303 stands for “Cylinder 3 Misfire Detected” which indicates that there have been numerous misfires in engine cylinder 3. After taking it to the Jeep dealership they told me its a cracked cylinder head. This was a fairly common issue with earlier year WK2 models, but continues to be a under-reported issue in later years.
