Service Shifter Issue

I know there's another thread about this way downstream, but I decided to open a new one.

Long time lurker - first time posting.

I have a 2018 Trailhawk with 27K miles and virtually no issues so far, that is until the dreaded "Service Shifter" warning light started intermittently showing up about 4 months ago. It happened first when shifting the transmission into manual mode heading downhill on a steep, rugged, 4WD logging road here in the Southern Oregon Siskiyou Mtns. All the red warning lights adjacent to the gear designations came on. Manual gearing was not available at all. Fortunately, stopping the vehicle, turning the engine off and back on seemed to reset everything. I made it home with no further issues.

This started happening with ever increasing regularity, almost predictably when I was off-highway on steep rock-crawling roads where I needed manual control the most. But turning the car off and back on always seemed to reset the warning.

I didn't worry that much until I read another Forum user's incredibly dangerous story of his transmission seizing at freeway speed, causing a near-tragic crash.

I took my Trailhawk to Lithia Jeep here in Medford, OR and the service department was not unaware of this particular issue. They replaced the transmission shifting wiring harness and relay at no charge to me.

I'll report again if there's anything further to discuss. I urge fellow owners to keep a close eye on this and take theirs in immediately if you see the "Service Shifter" warning.

I would guess that this problem must be approaching the threshold of a model-wide factory recall.

Lifted from FB poster:

Anyone out there who owns a 2017 jeep Cherokee please please be careful. Last night driving down interstate 79 (wv)our service shifter light came on 10 seconds later while doing 70 miles a hour what used to be my jeep locked the front wheels up and read park on the dash. No warning no nothing. When the wheels locked up it cause the jeep to spin hitting the back end of a 2 tiered car transport semi. No air bags where deployed. Ive already contacted Chrysler. They are opening a legal investigation. Please please please. If you know anyone who drives a 17 please please tell them if the service shifter light comes on. Pull over immediately! Even if the car seems to be driving normally. I could of lost a love one. Thank god skylar was camping. I dont want this to happen to anyone else. I hope they conduct their investigation quickly. And get this recall underway soon. My Jeep was a 2017 Cherokee Latitude 4x4 V6
EDIT: A WONDERFUL LADY SHOWED ME PHOTOS OF HER JEEP DOING THE SERVICE SHIFTER MALFUNCTION SO EVERYONE KNOWS WHAT TO LOOK FOR. ALSO NOW THAT MY HUSBAND IS LESS CONCUSSED HE SAID THE VEHICLE ACCELERATED BEFORE IT LOCKED UP.
***Also to all the nay sayers who say this is fake, i assure you its not. This was posted to save lives. And for those who say its impossible for a vehicle to go into park while traveling at such high speeds. This is a electronic shifter. Electronics malfunction all the time.. keep negative comments to yourselves seeing as this is something that did happen to my family***
Anyone who has had malfunctions please get your vin and either go to safercar.gov or call 1-888-327-4236

I own a 2019 Jeep Grand Cherokee limited model with about 53,XXX miles on it and last night 9/11/2023 while driving it shifted into Neutral !! and gave the "Service Shifter" message luckily no one else was one the road or around me when this happened. I am so very happy I was able to see all the posts here about this vehicle's gear shifter that has been a continuous problem for Stellantis 10 years with their Jeep models. This is dangerous and as you can see they HAVE NOT FIXED THIS PROBLEM !

I had both shift bezel and the wiring. TSB: 08-054-18 REV. A and new pigtail TSB: 08-103-18 done last Oct.. Now one year and 2 weeks later, same old "shifter service" light back on..Local jeep dealer said OEM parts have a one year warranty, I'll be charged again for another bezel replacement. Local jeep said take it up with Corporate office. Below is my request and response.

Howdy,
I have attached documents.
A little history of the "Service Shifter" fix attempted.

5089 miles
26646 miles
30864 miles
40598 miles
46872 miles
48268 miles
And this last one at 77781

And the light has come on several times in-between these trips to Jeep dealer.
The 48268 fix was out of warranty and I had to use my extended warranty to cover it. Which I feel was wrong, but the shop said Jeep has found a cure for the problem.
Now just a year and two weeks later same issue, then they tell me the replacement part has a one year warranty, and it's expired, by two weeks. And again I'm charged for replacement parts that Jeep knows will fail again.
We are a second generation Jeep family and hope this can be resolved.

I'm asking for my 200$ deductible refund. At the least.


Thank you,

Thank you for all your trolling posts whining about Jeep and your opinion that they don't care. It is a fun distraction to watch your silly venting and poor sense of humor. Of course every Jeep owner has serious problems with their KLs - that's why Jeep has sold over a million of them. Frankly, if I was as disappointed in my Jeep as you seem to be, I'd have sold the POS long ago. Caveat Emptor.

Message "service shifter" pops up on the instrument panel, and a series of red alert lights appear next to every gear on the automatic transmission shifter lever. This problem is rampant among 2017-2018 jeep cherokees!! The dealers are unable to fix the problem! They replace the wiring harness, they replace the shifters themselves, they reset the computers ? And the problem always returns! The website https://www.cargurus.com/cars/discussion-t68742_ds990296 alone contains the stories of over 80 jeep cherokee owners who have this ongoing problem. Imagine how many jeep owners across america are suffering with this issue! Jeep replaced the 2014 shifters that were recalled (the ones that killed star trek actor anton yelchin in 2016) with this new shifter - and this one is just as bad! These vehicles must be recalled!!

So this just happened to my wife's 2018 Cherokee at 50,500 miles. Question: Is this repair considered powertrain? Or is it considered bumper-to-bumper? I'm trying to gauge cost before I take it to the dealer.

So my dealer "did some research" and they *think* that the issue is the console bezel and wiring. Allegedly this has sensors in it that communicate shifter position with the PCM. When it fails, it causes all the lights to flash on like ours is doing and the message on the dash.

They're saying somewhere around $450 to repair out of pocket since we're at 50,000 miles. And they're also saying no ETA on parts, which is common with Stellantis products. They NEVER have repair parts available.

As bad as it hurts my soul, I'm trying to talk the wife into trading for a Toyota. This Cherokee has been nothing but a headache, and I'm a die hard Jeep guy but geez this is ridiculous.
