Steering, Electrical system, Lane departure, Jul 16, 2023
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.

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.

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.

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 .

All lights on dash light up while driving or in park, no power steering, all displays flickering, can not move vehicle. While in park, can not engage shifter, if I turn off vehicle while it’s on the “fritz”, vehicle might not start for some time (15-40 minutes), this has been on going since 11/22, three visits to dealership, two at an independent shop. Dealership claimed the couldn’t replicate issue/“concern” Vehicle is simply not safe. I’ve recorded many videos documenting these safety/vehicle issues. It’s been nearly 6 months of trying to get a reputable diagnosis, repair and answers. I hope this isn’t a scam? I truly need help.

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.

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.

2018 Jeep JLU Sahara 3.6 - Several weeks prior to January 2022 I noticed the Electronic Stop Start ESS feature was no longer working. There was also a message indicating the ESS was not working due to the battery charging. I took the Jeep to my mechanic (Not Jeep dealership mechanic) on January 14, 2022. The main battery voltage was checked and was above 12.7 volts. The auxiliary battery was checked and was approx 10.5 volts. I decided to replace the the auxiliary battery. Once replaced the ESS system started to work again and all electronic features returned to normal. Sometime in November 2022 the ESS stopped working. The ESS error message returned indicating the ESS was not working due to the battery charging. In late December 2022 the Jeep had a dead main (original) battery. The main battery was jumped and the vehicle started and ran normally for about a week. The voltage was checked several times using the voltage meter in the settings menu. Each time the voltage showed reading above 14 volts. One week after the first dead battery the battery went dead again. It was jumped again and started. The vehicle remained on and in park for one hour and was then driven. During the test drive I stopped the Jeep momentarily in the roadway to check the ignition. The Jeep did not start and could not be jumped. As a result of the battery failure my vehicle was blocking the roadway and could not be shifted out of park and into neutral. This was a dangerous situation. Later the voltage on both batteries was checked. The main batt voltage was 10.5 and the aux battery was 10.8 volts. This is a 2018 Jeep JLU. The first aux battery failed and was replaced in January 2022. The second aux battery has failed and will be replaced in January 2023 along with the main (original) battery. Three battery failures in one year is not acceptable.
