The power steering went out while driving, check engine light came on, ABS Service, Service Shifter, Start/Stop unavailable, Service 4wd, Auto Park Disabled, Blind Spot Alert, Electronic Stability Control Service, Parking Sense Off. I could not shift out of Park. Many people are having this problem with their 2018 Wrangler JL and JLU and later models. All you have to do is Google this or go to YouTube to see. It may be a faulty ECU. In any case, this is a problem and a safety hazard.

When driving, vehicle will start throwing codes and lights, losing power steering and at times after this happens will not shift out of park. Also after this happens sometimes it will not start or shut off.

My Jeep has been having electrical problems many warnings across the dash including lost communication with ABS module this has been going on for about a month sometimes the fault won-??t let the Jeep go into gear I brought it to the local dealership they had it for the entire day and was told they can-??t find anything and that it would actually have to be happening for them to figure it out yesterday I was driving with my kids in the Jeep and the electrical want crazy and then I lost total steering while doing 55 miles per hour After my heart went through my chest I was able to get the vehicle stopped so according to my Jeep dealer I need to be in a near death crash in order for them to figure out the problem I wonder if any unexplained deaths involving newer Jeep Wrangler could be attributed to these electrical issues

The electronic dash unit (Stereo) that controls Navigation, climate, media and all other consumer input, changes the screen without touching it. The 8.4 unit is the main point of contact for a driver with the vehicle. The navigation blinks and switches areas with no touch on the screen. The dangers of the distraction is obvious to me. If they can-??t make a decent unit for their expensive vehicles, maybe they should leave it out or just stop making vehicles. It-??s obvious they have zero concern for customers-?? safety. This is a known issue to Jeep, Chrysler, Stellantis or whatever the carmaker-du jour is!! It-??s sickening what a company can get away with in this country.

In the middle of the intersection, the power steering turned off and the steering wheel locked. I could not move the steering. All dashboard lights came on as well as the emergency brakes. The gear shift also locked and refused to shift into any toner gear. The vehicle was completely disabled and would not restart. This is the 5 time this has happened. I took it to get serviced at my local jeep Chrysler dodge dealership and I am still receiving the same issue.

When driving or starting up the dashboard & radio will be pitch black not showing anything. Now when I started it up the other day I went to stop at a light and the Auto Shut Off warning light popped on and just stopped working. It will frequently reboot itself by radio standards and shut down the entire jeep system.

The U-Connect screen is de-laminating. It is also disconnecting the Bluetooth connections for the phone and directions, changing input selections and volume randomly. This is causing me to have to use my phone and try to reconnect or look at the screen to see what's going on. This is causing me to be distracted while driving and also having to stop several times causing delays to deal with the screen not working properly.

This car lost power steering while driving on the expresway. The lights blink, windshield wipers go off, and all the warning lights flash. It will stop and not allow you to drive. I was told it was fixed after a software update but it continues to happen and it's gotten worse. They are now saying it needs a wire harness replacement. This vehicle is very dangerous.

vehicle dash goes crazy. all warning lights come on. gauges act erratic. shifter lights blink. service abs, service traction control, service shift warnings flash. fans act erratic. power steering cuts out. when in park vehicle won't shift out of park. sometimes this happens when vehicle is first started. it is now happening while driving. this is a major safety concern since the power steering goes out while driving. i have had this vehicle to the dealership 3 times for this and they keep telling me they can't recreate the problem. when put on the scanner numerous codes come up.

At 40,000 miles the Service shifter warning light came on and a barrage of other lights flashed across the dash. Check engine light comes on and all of a sudden I lose all power steering and almost run off the road. The steering only comes back after shutting engine off and restarting it. It is a continuous problem with no warning as to when it will occur. I have it scheduled to go into shop on Thursday for the diagnosis. Either way it is extremely dangerous!

1) Compromised Battery (a battery purchased in August of 2021 from Interstate Battery|Camp Bowie Blvd|FortWorthTx) 2) Moritz Service Team explained some batteries (via the 3 manufacturers) can have a fail rate or be bad batteries 3) Moritz could not replicate extent of the issues we experienced with a collapsed electrical system on 02.24.2022. 4) Moritz could not explain why the 3rd party purchased battery was -??discharged-?? completely after driving the Jeep and stopping for a short period resulting in the collapse of electrical system. 5) Moritz Team and GM had no explanation for the replacement of 3 batteries for this Jeep in a short period of < 3 years. 6) Moritz Team and GM suggested they have no knowledge of this Jeep product having these type of electrical issues. (See link: https://www.nhtsa.gov/vehicle/2018/JEEP/WRANGLER/SUV/4WD%252520Later%252520Release#safety-ratings-frontal) 7) Moritz Service Team and GM recommended returning the battery to its place of purchase for a warranty trade in. 8) Moritz Service Team and GM proposed if a repeat of this event occurs that: A) Moritz Service Team provide a more expansed evaluation of this issue (requiring our solo mode of transportation to be in the shop for an extended period) B) Should Moritz Service Team be unable to identify and replicate issue: a STAR report be submitted to escalate issue to next level engineers for Moritz. As an update: We delivered the Jeep with the 3rd party purchased battery back to Interstate Battery as recommended (following our meeting). Multiple tests were performed and noted that the 12V 48 AGM 60 G-48 (SLI48AGMDP) battery registered each time above 775. ISSUE UNRESOLVED: The issue remains how a fully charged battery (with no effect of user error), driven appropriately, resulted in a full electrical collapse of this Jeep Wrangler Unltd. Rubicon JL system within 30 minutes of the ignition beiNG turned off and attempted restart. MFG 10.2018

When you put the car in reverse the screen turns blue. Many drivers of this same vehicle has said they all experience a blue screen of death. I took it to a body shop today and they said it-??s because of faulty wiring during manufacturing. A lot of jeep drivers are experiencing this same issue. Jeep dealers do not know what to do. Please issue a recall before someone gets hurt reversing their car.

When driving, at random times my dash lights all come on and the following components say that they're unavailable: ABS Electronic Stability Control Sway Bar Disconnect Stop/Start Blind Spot Alert I will then lose my power steering. My speedometer, RPM, and fuel gauges will drop to 0. This has happened both when driving around the neighborhood and while driving on the highway. I have been to two different dealers three different times and they have been able to reproduce and confirm the issue. But they have been unable to fix the problem. Researching the issue myself, I have found several examples of other owners having this same problem. Examples can be found on carcomplaints.com and jlwranglerforums.com. I don't know how many other cars must have this issue before action is taken by the manufacturer, but I consider the loss of power steering and the airbag system a significant safety issue. My vehicle is available for inspection at any time.

Just took my 2018 JEEP Wrangler Unlimited JL in for the improved steering feel recall. The jeep was working just fine until after the software update just miles after update lost all power and shut off and wouldn't restart. I couldn't even get it to turn over enough to put it in neutral to put it on a tow truck. Finally got it restarted, back to the dealer and was told fuel pump was out. Service Bulletin #S1808000167, FCA discusses the reasons that the vehicle won-??t start or there is lost contact with the fuel pump control module.

Multiple occurances of steering locking up(power steering failure?)all on cold mornings, turning left and around 35-40 mph 12/21/21: While driving down a straight 2 lane rd prior to dawn, I lightly steered my vehicle right to move from center of rd to right hand side. When I attempted to steer back left to correct the vehicle straight, I was unable to move the steering wheel at all to the left resulting in me driving into a mailbox & damaged both vehicle & mailbox. Vehicle drove home fine w/out further steering issue and problem couldn't be replicated. 1/11/22: Another cold morning(appr 32 degrees), warmed car up for 15 mins(to take kids to school). Came to a 30 degree left turn & again noticed the same issue of steering locked up and unable to turn left into curve until I used both hands/arms to apply a significant amount of physical force(again barely missing a mailbox). Then I couldn't correct back to the right w/out applying same force so ended up in oncoming lane of traffic. Thankfully there was not an oncoming vehicle since I had 2 kids in the car & could've had a head on collision. Steering started working again before vehicle even came to a stop. 1/27/21: Cold morning again, warmed car up as usual, & had the same steering failure on same left hand curve as on 1/11 but this time steering ability returned quickly and safely made through the turn. Oncoming vehicle but steering returned quickly enough to avoid issues. I've since learned that FCA has a new 'campaign' out for the steering assist categorized as a 'non-safety related' repair. I'm uncertain if the 'software update' will address my steering issue as the factors outlined in it are not the same as my circumstance & correspond with a different issue being reported with the steering.?
