While operating the vehicle, I lost Power Steering, Stability Control, Anti-Lock Brakes and when I was able to stop, the transmission was put into park and I was unable to shift gears. Dealership informed me that this is a known issue related to the Can Bus Connector located behind the glove compartment, which apparently controls all of the safety systems. There were multiple indicators lit on the dashboard along with a check engine light. Dealership is replacing the connector.

All the lights on the Jeep came on. Locked up nearly had a wreck. Had to be towed. Now dealership is saying its the motor. Everything shut down. This is not the first time the jeep has shut all the way down. This is very dangerous. We had replaced the starter, and battery and spark plugs and box. The jeep worked for a day then the second starter burned up.

The contact owns a 2018 Jeep Wrangler. The contact stated while driving 25 MPH, the check engine warning light illuminated. The contact was able to drive to the residence, where she parked and turned off the vehicle. The contact stated upon restarting the vehicle, the vehicle operated as needed. The dealer was notified of the failure and advised the contact to take the vehicle to their location for a diagnostic test. The contact stated that upon starting the vehicle and attempting to shift into drive(D), the gear shifter seized. The vehicle responded as needed after several attempts. The vehicle was taken to the dealer; however, the failure could not be duplicated. The dealer received remote assistance from Jeep engineers. Additionally, the contact stated while driving at an undisclosed speed, the messages "4WD Disabled", "Parking System Disabled", "Park" and other unknown messages were displayed. The traction control warning light, the check engine warning light and other unknown warning lights were illuminated. The vehicle was taken to the dealer, who cleared the codes, but could not duplicate the failure. The contact stated while driving 30-35 MPH, the windshield wipers engaged independently, the fuel gauge fluctuated up and down. Additionally, several unknown warning lights were illuminated. The vehicle lost power steering functionality. The brake pedal was depressed, but the vehicle hesitated to respond. The contact was able to pull into a parking lot. The vehicle was towed to the residence of the contact's daughter. The contact stated upon restarting the vehicle, the TPMS and other unknown warning lights were illuminated. The vehicle was then towed to the dealer to be diagnosed. The vehicle was not yet diagnosed nor repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 88,000.

Driving along at highway speed. lost power steering. All lights lit on dash. center LCD screen was giving warnings that all systems had failed. Anti lock brakes, gear selector, can bus systems, audio and GPS systems. Fortunately i was driving on a straight highway. I've looked into this issue. Its called the Christmas tree event. As all problem lights on dash light up. It looks like the fix is replacing 2 CANBUS ports behind glove box.

My JEEP STOPPED IN THE MIDDLE OF THE ROAD, would not charge AND WOULD NOT CHANGE GEAR from park. I have less than 52,000 miles

All the warning lights turn on tachometer stops working and sometimes it looses power steering. I was driving about 45mph when all the warning lights turned on and I lost power steering. I had to pull over luckily it was when going straight. Very scary took to dealer they said they could not replicate picked up car 3days later happened again

My wife was driving her Jeep to work this morning and a warning message came on the info screen stating the vehicle was shutting down soon and to safely pull over. She only had a two minute warning which was not enough time to pull over to a safe place without risking injury from being hit from another vehicle. The Jeep ended up and powered down within the two minutes of receiving the warning which caused loss of engine power, no power steering and no power brakes. This seems to be a pretty dangerous combination. It literally left her in the roadway. We had the batteries checked and they are ok. The vehicle did start back but the warning light came on again so it is parked until we can get it towed to the dealership. Researching it online it seems to be a common issue with the 2018 JLU. She currently has 117,000 miles on the Jeep.

Electrical going haywire. While in drive it just wouldn-??t do anything the gear shift -??D-?? was blinking so I rolled to a safe place (thank god I was not on the freeway) turned it off then back on again apparently this is now a known problem not only for 2018 some were 2019 & 2020-??-?? please investigate

- South Weber, UT, USA

For the last year on several occasions the power steering locks up and I am unable to control the vehicle. The lights on my dash start flickering and the vehicle starts stuttering like it is out of gas. It seems like an electrical issue where the vehicle is getting mixed signals so the power steering locks up. On 2 occasions while in motion I tried to turn off the road causing the vehicle to stall into oncoming traffic. My jeep has been at the dealership at least 4 times for the same issue and I have had 3 active cases through Chrysler. This happened again a few days ago and the Jeep is currently at the dealership. This is a real concern, and I-??m scared for my safety while driving. This is an issue that happens at random times and then the vehicle returns to normal function.

2018 Jeep Wrangler (JL) Sahara Safety features all disable with this issue: Power steering (this could happen on the highway) Stability (STC), Antilock Braking, Blind spot, etc. While driving their appears to be an electrical short. The steering wheel locks up and all lights on dashboard come on. Several error messages "Auto Park Disabled", "Speed Control Messaging Unavailable", "Service Antilock Brake System", "Service Transmission Continue in DRIVE. Do Not Shift or Turn Off Engine" - to name a few. Dealers turn me way with simple computer reboot solutions only for issue to reoccur. Issue presents itself intermittently. Dealer has regularly turned me away for being unable to replicate in non driving conditions.

I have taken vehicle into jeep 4 times in less than 2 years. Auto start stop (ESS) fails first then check engine comes on right after car shuts off on own WHILE driving & stalls hard. We have been rear ended because of it thankfully we were not on freeway after googling and asking jeep community this is VERY COMMON in these jeeps. Aux battery goes dead and causes this issue and burns out a fuse and the main battery. We have replaced battery 4+ times now because of this issue. This is a saftey hazard thankfully the times it shuts off on us isn-??t on the freeway where it can cause a multi vehicle collision most recent incident was 04/02/2023

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?

On multiple occasions I have been driving to work (45 min drive) when all of my dash lights and emergency lights go on. I am then notified on the dash of start /stop system failure(which is off), The emergency hand brake light is on, electric stability control failure, service antilock break system, auto park disabled and my radio volume going to max. This is then followed by my power steering or something locks up not allowing me to steer my car that is in motion! Once I stop I turn the car off and it won-€™t start again. I have waited 20 min and restart the car which then the shifter won-€™t let me put into drive! This has happened mulitple times and I have taken to my trusted mechanic to repair but was informed it is a recall on my vehicle-€¦. When I look up my vin no recall reported so he gave me a form of the recall. Please help me, I-€™m honestly scared to drive my car because I don-€™t want this to happen while I-€™m on a highway or cause me to be in an accident. I shouldn-€™t be scared to drive my car.

Driving on highway at 75MPH, chime followed by all warning lights. Speedometer falls to zero and a series of system failures scrolls through on message board. While taking the exit ramp, power steering fails halfway through the loop. Speedometer returns to normal momentarily, then jumps back and forth until destination. Power steering does not return.

- Derby, KS, USA

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.

- St. Augustine, FL, USA

As I was driving, all my warning lights started going off. The dash said everything was unavailable (disconnect sway bar, traction control, shifter, etc). Power steering went out and the car was put into auto park while moving and the shifter wouldn-€™t work. Windows wouldn-€™t work, radio volume started changing, etc.
