2018 Jeep Cherokee Electrical System

Service shifter message and all gear indicator lights on PRND. Seeing common problem and a Technical Bulletin on 2014-2018 Jeep Cherokees

The contact owns a 2018 Jeep Cherokee. The contact stated while operating the vehicle, the instrument panel light, dome light, and center console continuously flickered off and on with the battery voltage charge erroneously fluctuating up and down from 10 to 14 Volts. The vehicle was taken to the local dealer who replaced the alternator, but the failure persisted. The vehicle was taken back to the local dealer who determined that the PCM was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was provided. The contact was informed that the VIN was not included in NHTSA Campaign Number: 18V524000 (ELECTRICAL SYSTEM). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 133,000.

All lights on the gear shift light up and a message on the display says service shifter. Happens randomly. Have to turn car off and back on to get to clear. Yesterday I had to turn car off and back on 3 times before error would reset. Found online this is happening to a lot of Jeep cherokees and most common fix is to replace the shifter bezel and wiring. So I replaced the shift bezel and wiring harness yesterday.

I have had the service shifter warning light come on after I start the vehicle. The most recent incident is today. Sometimes it comes on and I cannot start the vehicle. I have also had it come on and then my vehicle dies. The I have taken it in and been told no code comes up so nothing is wrong. But clearly something is wrong.

Service shifter light came on and gear shift lights are all red,P,R,N,D. Took it in and they said it was the shifter harness and they changed it. Didn’t have the issue for a while and it started again January & February 2021, September 2022, June 2023, August 2023, and now ever day in 2024. Have to turn off vehicle and restart. Took to dealer and they said that it’s the shifter harness after they already had changed it. Please help, cause when driving, you can’t figure out in what gear it in and you can’t see your speedometer’s speed. Thanks!

Error popped up on the dash saying Service Shifter, all the lights on the gears lit up. First occurrence, I was able to turn the car off and the error went away. 1 week later, it came back and has not gone away. Was unable to put car into drive.

Randomly and more often occurring, I turn on my vehicle and it tells me "service shifter" and all of the lights on the shifter turn red. I can restart the vehicle and it may or may not come back. This happened to me when I first bought the vehicle and they told me that they could not get the message to come up. Oddly enough, the message did not come up for years until just recently it has been happening again. My center console screen between my speedometer and my odometer just says "service shifter".

The contact owns a 2018 Jeep Cherokee. The contact stated that while driving at an undisclosed speed, the vehicle stalled with several unknown warning lights illuminated. The vehicle was taken to the dealer, and an unknown repair was performed; however, the failure recurred. The vehicle was taken back to the dealer, who informed the contact the vehicle had an electrical failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 46,000.

While driving I receive warnings I need to service my shifter. Warning stays on instrument panel and disables all other settings and screen. Also all lights light up on shifter unable to see which gear the car is in. THIS IS STILL HAPPENING EVEN AFTER i GET MY OIL CHANGE. AND THEY RESET THE OIL CHANGE.

The system that failed was the fuse panel that controls the engine and the steering of the car. How this put my safety at risk was I lost all control over the car I could not steer or get the car to turn back on for about 30 minutes. The problem has been reproduced by the dealer. The vehicle has been inspected by the manufacturer. There we no issues prior to the failure.

Floor shifter jumper wiring harness. Manufacturer Part Number: 68413957AA. This is a common issue with these vehicles. This happens out of nowhere and is not something that happens due to wear or old age. This should be a recall due to the safety of the driver.

Gear Shifter says servicer gear shift and does not recognize the car is in park.

Service shifter message comes on while reversing the car and all the lights on shifter come on and car suddenly stops.

Service shifter error

ATTEMPTED TO ACTIVATE THE ELECTRONIC RANGE SELECT (ERS) WHILE DRIVING. IMMEDIATELY, ALL OF THE PRNDL LIGHTS ILLUMINATED RED AND THE DASH DISPLAYED THE MESSAGE "SHIFTER SERVICE". MOVING THE SHIFTER BACK TO FULLY AUTOMATIC DID NOT CLEAR THE ERROR OR THE PRNDL LIGHTS. I STOPPED THE VEHICLE, TURNED IT OFF, THEN RESTARTED THE ENGINE AND THE ERROR CLEARED.

I HAVE ONLY HAD MY CAR 3 YEARS AND MY CAR IS ASKING FOR A SHIFTER SERVICE. THE 4 LIGHTS TURN ON. MY CAR SHUTS OFF WHEN I DRIVE AND MESSAGE SAID IT WENT FROM DRIVE TO PARK AND SHUTS OFF. THIS IS A SAFETY ISSUE BECAUSE IT JUST SHUTS OFF WHEN I AM DRIVING. IT CAN CAUSE AN ACCIDENT. I HAVE LET THE DEALER SHIP KNOW OF THE ISSUE. I SHOULD NOT HAVE TO PAY FOR A DEFECT. I TRULY BELIEVE THAT THIS A MANUFACTURE DEFECT AND I SHOULD NOT BE RESPONSIBLE FOR THE REPAIRS. I HAVE NEVER HAD AN ISSUE WITH A SHIFTER AND ITS ONLY BEEN 3 YEARS THAT I HAD MY CAR. I ONLY HAVE 60,088 MILES. THIS STARTED ABOUT A MONTH AGO.

MY JEEP WOULDNT START(05/04/2021) SO I BOUGHT A NEW BATTERY (05/05/2021).BUT I NOTICE TODAY (05/06/2021)THAT THE CLOCK HAD RESET ON IT OWN( SO I GOT TO NE LOSING POWER) AND MY SERVICE SHIFTER CAME ON AA WELL WHILE IN MOTION

Everytime we drive our vehicle for longer than 10 minutes a warning indicator light comes on which says "service shifter". All the lights on the shifter come on and you can no longer tell when you are in drive, park, etc. When you turn the vehicle off the system resets, but it will come back on again. The dealership inspected it and found no fix for the issue. To me, this seems highly irresponsible and reckless to allow something like this to occur in a vehicle. Numerous people with Jeep Cherokees have experienced the same thing and I believe there needs to be a recal related to the shifting/electrical system.

'SERVICE SHIFTER' COMES ON. DEALER SAYS THERE'S NO ISSUE. THIS HAS HAPPENED WHILE I'M DRIVING AND AT IGNITION START UP.

AT VARIOUS TIMES, EITHER STARTING THE CAR OR RESTARTING THE CAR, NOT ALL THE TIME, THE SERVICE SHIFTER LIGHT WILL ILLIMUNATE ON THE SCREEN BLOCKING OUT THE DIGITAL SPEEDOMETER AND LIGHTING UP THE SHIFTER TO ALL RED. AFTER SHUTTING DOWN THE CAR AND RESTARTING (SOMETIMES) THE LIGHT WILL GO OUT AND THE CAR WILL RUN FINE. I CONTACTED THE DEALERSHIP AND THE IT IS NOT COVERED BY EITHER THE BASIC WARRANTY OR THE EXTENDED WARRANTY AND THE RESOLUTION IS TO CHANGE THE WHOLE SHIFTER ASSEMBLY AT AN ESTIMATED COST OF OVER $600.00.

'SERVICE SHIFTER' ERROR CODE STARTED APPEARING ON DASHBOARD WITH ALL GEAR LIGHTS LIT UP NEXT TO THE SHIFTER. PROBLEM RESOLVED ITSELF AFTER RESTARTING THE VEHICLE. MILEAGE AT APPROX 37K MILES, IDENTIFIED AS 'TRANSMISSION SHIFT ELECTRICAL FAILURE' BY JEEP DEALERSHIP AND REPLACED FOR AROUND $700

WAS DRIVING AND VEHICLE STOPPED MOVING. PULLED OVER AND SERVICE ELECTRICAL THROTTLE CONTROL CAME ON. FINALLY GOT THE VEHICLE TO DRIVE. CHECK ENGINE LIGHT IS ON NOW.

ELECTRONIC THROTTLE CONTROL LIGHT CAME ON- THIS HAS HAPPENED THREE TIMES, ONCE WHILD DRIVING AND TWICE WHEN STARTING THE CAR AND IT WAS IN PARK.
