Recurring issue with my Jeep where seemingly every light on the dash, as well as the blind spot detectors, illuminates. The lights are accompanies by warning messages that indicate that electronic stability control and parking sense are unavailable. ABS lights, Traction Control, stability control, the brake light, and prompts to service 4WD are present. The impact varies based on whether or not the car is in motion. When it is not, as in the case of a cold start, the transmission is locked in Park. When the car is in motion, power steering intermittently goes out. If you pull over and put the vehicle in park while the lights are illuminated (i.e. if they don't clear), the car will get stuck in park until the lights clear. I have had the vehicle towed to the Jeep dealership in Natick, MA twice and, while they've charged me nothing, they've been unable to help due to the issue clearing and a lack of persistent diagnostic logs. Aside from the inconvenience, the sudden loss of power steering presents a safety issue. This has been going on for months, though the safety concern with steering only presented yesterday.

While driving vehicle will randomly have multiple warning lights on display suddenly appear (ABS, check engine, stability control, traction control, etc.) and speedometer would either go to 0 or read blank. In some instances power steering also cut out causing vehicle to swerve or jerk without warning. Spouse was scared to drive it when this happened and pulled over to have it towed. Did not want to have the vehicle suddenly swerve or lose control and hit cross traffic or pedestrian on side walk. This issue would then suddenly resolve itself and return to normal state. On some occasions, when vehicle was started, it would not shift out of park at first, but then would correct itself and allow it to be shifted out of park and driven. When check engine light was active, had codes checked and none were active, only stored. Indicated ABS sensor or ABS module errors. Was able to have Chrysler Dealer check into and after 5 days of troubleshooting, they worked with Chrysler Engineering to determine that there was a star CAN connector that was malfunctioning. Installed part 68321746AA for $84 and labor of $527 to resolve issue.

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 35 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. The contact stated the vehicle couldn't be diagnosed and out of pocket for rental and repairs for the vehicle.

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 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.

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
