One day out of the blue, my Jeep Wrangler received a "Service Shifter" error code. The error code threw about 40 other codes at the same time. Loss of power steering, loss of abs, engine kept revving on its own, windshield wipers turned on. While in park it felt as if it was trying to shift itself into other gears. Loss of steering while driving as well as the engine revving up and down while on the interstate. Every warning light came on and stayed on. I can let it sit for awhile and it'll drive fine for a little while until it does it all again and again. I have not taken it to a dealership yet due to all the threads on being charged $2000 and it not get fixed.

The check engine light came on in my car. I was waiting for the dealer to call me to fix it for the 3rd time. I was on my way home when every electrical option on the vehicle turned on- wipers, lights, dash lights, brake- which caused the car to brake- then it turned off and I had no brakes, the car had no steering, it accelerated and I went off the road.

First it was my clutch blowing up including the transmission from underneath me while I drove down a hwy. Then it was a month later before I got it back. (I'm single, and it's my only vehicle). Once I got my jeep back the start/stop button stopped working. I had to lock/unlock with the key fob for it to start. Even with both fobs in the jeep. Now every code, 101 to be exact) is being thrown out of nowhere. Every light goes off, the wipers start going off, the sway bar and traction control disconnects while I'm driving along with the steering wheel locking up while I'm driving down the hwy. The brakes are pulling very badky to the left and /or right. The entire thing is absolutely a death trap. I can't believe this was passed by someone who has the customers best interest for safety. I'd like to know if any of this is recalled because it's been every jeep from 2018-2021 that have this issues. Also 5th gear now vibrats pretty bad.

Displays, "Service Shifter". Often followed by many, mostly random warnings, gauges fluctuate wildly, and disabled stop/start, traction and stability control; and sometimes loses power steering, and stalls and won't restart. The stereo volume, wipers, and cabin fan speed also can fluctuate wildly; worst case. This issue first appeared after going through a puddle, and seems to be exacerbated by high EMF areas; this is only corollary. This vehicle has never been used roughly or off road. The obvious dangers are, spontaneous maniacal warnings are a significant distraction to driving; if stop/start is not disabled vehicle will not start after stop at intersection, causing disruption to traffic; if power steering randomly stops working, which occurs while stopped or driving, the vehicle is nearly impossible to drive, and can only practically be driven by a strongman athlete. The coup de grâce where everything goes berserk, is usually when parked and attempting to reset the condition. The problem has not been reproduced by a dealer or service center; I have spent days inspecting grounds, harnesses, and inspecting, cleaning and replacing connectors. There's also a long list of mostly random codes for nearly everything, including the persistent lost communication with TCM. Up to October 2022 and 66,000 miles the only warnings or codes were for, wheel sensor (rep under warrantee), and "Small Leak In Vapor Recovery System" (leaky gas cap). A month+ after the warrantee expired, at about 66,000 mi, the vehicle began to generate random warnings and codes, and became unbearable (and dangerous) to drive. My observations and inspections and limited testing (haven't probed system circuits directly) lead to an assertion that the problem is system wide; many wildly various, mostly non repeatable, codes are recorded, systems that shut down are wildly various and not always repeatable; like there's nothing specifically or consistently wrong-but everything is failing. 5V reg in TCM?

For several months the vehicle will randomly throw of multiple warnings while driving such as, service gaer shifter, may not be able to shift until your destination, traction control not working, abs not working, high speed fan randomly turns, windshield wipers randomly come on. Several times I even lost power steering while driving. This was very scary and unsafe as I had a very hard time turning off the main road into a parking to wait it out. Tool vehicle to dealer with no results. This is not a new issue. There are various on-line forums with many many people having the same issue and same results from dealers- Nothing. The manufacture has to be put on notice and figure this out and issue a recall to fix.
