Shift to park warning on other Cherokee years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2019, 2020, 2021, 2022.
What this problem usually is
This sheet covers a dash message that says "Shift to Park" or "Service Shifter" when the car is already in Park, or when it's sitting in Drive with the shifter lights glowing. Owners say it won't let them turn the car off, or it flashes up on the highway.
What got replaced
Owners who name the part that was replaced mention the wiring harness (18 reports) and the shifter assembly (9 reports).
Recalls and investigations
5 recalls on the transmission and drivetrain cover the 2018 model year. A recall on the same system isn't always the same failure, so read the defect text.
The power transfer unit (PTU) may become damaged and disengage the transmission and differential, resulting in a loss of drive power and/or loss of park function.
The powertrain control module may be equipped with a voltage regulator chip in the circuit board that may fail, causing a stall or a no start condition.
The bearing cage for the right front halfshaft assembly may not have been properly heat treated, possibly resulting in the bearing cage breaking and a potential halfshaft assembly failure.
These vehicles are being recalled to address a defect that could prevent the cruise control system from disengaging.
The engines may have a cracked oil pump housing that can result in oil pump failure.

Is this a known problem?
The manufacturer has sent NHTSA 1 service bulletin or notice for the 2018 Jeep Cherokee that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

What owners wrote
“The SERVICE 4wd light came on at 206,000 miles in February . Had mechanic put code reader on and stated that the PTU is faulty. Then the service shifter light is on as well in February at 206,000 miles. It is a 2018 jeep Cherokee latitude. When checking recall my vehicle has no recall on it.”

“The "service shifter" message came on while driving. This issue was repaired at the dealership before when I still had the warranty. They said it was faulty and repaired it. Now the light is on again when I have just 68000 miles. Sounds like it is faulty again. Should there be a recall?”

“Since the car hit 20,000 miles, the "Service shifter" light will come on randomly. The dealership has had to "replace" the shifter components twice. And now it will come on when you put the car into reverse. This is a faulty part which needs to be replaced.”

“"Service Shifter" came up once around 36k miles and went away after engine restart. Shifter turns completely red. "Service Shifter" has now come up every time I begin driving. Vehicle has around 42k miles now.”

Should you keep driving it?
This page can't tell you that. 1 of 243 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
