Selected complaints filed with NHTSA by 2018 Jeep Cherokee owners, lightly cleaned up (personal details are redacted by NHTSA).
The rear defroster or related electrical wiring in the rear glass/liftgate area appears to have malfunctioned and shorted, causing a fire while the vehicle was parked, turned off, and unattended. The fire resulted in the rear glass shattering/blowing out. The incident was recorded on a residential security camera. This posed a significant safety risk because the fire started while the vehicle was off, creating danger to occupants, bystanders, nearby vehicles, and surrounding property. There were no prior warning indicators, messages, or symptoms known before the failure. A dealership has inspected the vehicle and provided a repair estimate consistent with failure in the rear defroster/rear glass area. The vehicle and damaged components should be available for inspection. …

This vehicle is designed to be a flat tow vehicle for a class a motorhome. No one made me aware of the death wobble and this caused an accident which could have been deadly. We did 13,000 dollars in damages to my motorhome and jeep. After hours of research i found this to be a common problem from Jeep. i contacted the local jeep service department and they were not aware of this. Come to find out there is a jeep part to correct the problem, at a cost of $286.39 and a labor charge of $460.00 to install. If jeep is aware of this problem, why are they not advising the public to not flat tow this jeep until the necessary parts are installed. There is nothing in the manuals regarding this problem!

The service shifter light keeps coming on. Sometimes when stopped in traffic the vehicle's transmission will shift from drive, to some unknown position, then the engine will stall out when attempting to go forward with traffic. The car will then not start and the shifter will not allow any gear shifting to be done. Can not be put into neutral in order to be push or easily towed. This has happened 4 time within the past 18 months. Each time the dealership acts surprised and responds that they have never heard of a service shifter issue before. They tried a software update, which didn't help. They also stated that they could replace several parts that added up to over $2000. Stated it wasn't their problem since it is out of warranty. Yes, it is available for inspection. …
the infotainment screen flashes a warning on red screen "911 Car Phone malfunction contact dealer". It has done this intermitently for the past couple of weeks. A few times I've started the vehicle and the screen is black, no back up camera, no a/c, no back up warning tone (I back up the vehicle from parking spot using the mirrors and the screen comes on a few minutes after vehicle is moving). I am concerned because I don't know what else isn't working and if something electrical will fail while driving. A couple of weeks ago I made an appt with the local jeep dealer and today was told I need a new radio at the cost of at least $1250 (the dealer has ordered a new radio could take a couple days to a few weeks he wasn't sure). …
In the beginning of July, the parking brake engaged on its own and a warning came up on the dash. It took some jockying to get the brake to disengage but it continued to happen. We took it to the dealer where purchased who told us that the parking brake control module was damaged by water and that bedause of this the extended warranty that we purchased for a few thousand dollars would not cover it (even though we were told it covered everything). The dealer wanted $2000 to fix it. I took the Jeep to a qualified mechanic whom I deal with, and he replaced the the control unit. We picked up the car and a week or so later the brake came on again. We took it back to the mechanic who dug deeper and found out that the body of the car was leaking, and water had run down and into the control unit again. …
Within the last 6 months this vehicle has left me stranded at least 5 times. The first time it overheated because the heating coil is so close to another line that is created a hole that caused the vehicle to overheat. The second time was an ignition coil. The third time was because it was time for an oil change which was not the case because it wasn't even time for an oil change. The other times were (battery) related but yet with the battery being replaced 200 bucks later I am left stranded on the road in the middle of traffic without any indication that it was going to cutoff. I fear taking it on the interstate. Within the last 24 hours I have been left stranded after having the dealership again yesterday tell me I need a new battery which I replaced but yet broke down again this morning. …
