I have been having electrical problems with my jeep for a couple of months. I took it in to my jeep dealer that found over fifty problem codes. They cleared the codes and drove it for 180 miles over two weeks and could not get anything to duplicate. Some codes- service shifter, abs not communicating, engine light, no speedometer, sway bar service, service 4 wheel drive, cruise control off, remote start off, and more. They had me take it home and let them know if it continues. It did so I took it to a different mechanic and he came up with 72 codes and he couldn-??t track any of them to a source. So I picked it up today and on the way home on the interstate curved overpass going 65 it suddenly veered to the right at the retaining wall. The power steering quite. It was all I could do to keep it from hitting the wall. If it would of been my wife driving she would of wrecked. I was almost home and was able to muscle it home barley able to turn into the drive way. After a while I went back outside and started it and the power steering worked just fine.

Several electrical issues, vehicle issues tying back to the CAN BUSS. The vehicle throws several codes and several components quit working. I lost powering steering at 80 M.P.H and had to fight the vehicle not to wreck out. Then the power steering comes back to function again almost causing me to wreck out. Traction control also stops working when this issue occurs, which is also incredibly dangerous. The vehicle then starts jerking and becoming unresponsive. New batteries, changed Can Buss connectors and no solution. There are hundreds of reported issues with this on the forums. Chrysler and Fiat should be held responsible. These issues are going to be the cause of someone's death. Just because this incident did not involve a "crash, fire or death" does not mean the next will not.

Every dash warning lights come on, radio cuts off, steering loss occurs, have to fight steering to get pulled over, turn it off and back on, sometimes resets but not always. Issue happens at random but the last time it occurred around a curve, nearly went off the road because of the steering loss. Had all the wires and grounds cleaned & checked, all batteries are good, alternator is good, all relays are good.

The Wrangler will shift out of gear and into neutral and steering become very hard and difficult to maneuver while accelerating from a stopped position and at times at highway speed. On the highway one can coast to the side of the road and shut off engine and restart and move again. This can also be done at an intersection but big safety concerns when pulling onto a highway with traffic, Multiple check lights will come on including check engine, stability control and service shifter. The Jeep has been taken to the dearer for repair to no resolve. Codes are cleared and problem persists. Began at about 70k miles and has persisted since.

Began receiving hundreds of error codes. The vehicle, while operating, would have the lockers engage, disengage, wouldn't start suddenly, ABS activated, sway bar disengaging, and other things. This represented a tremendous saftey risk for any occupants and was quite frightening. We had it at the dealership several times. We spent $1000 replacing both batteries and all harnesses were checked. The problem improved but never was fully resolved. Now a year after all of that work, we are experiencing more problems again.

I have had the rear defroster tab re soldered at dealer under warranty. I don't use the rear defroster because it is parked in garage. After a cold spell at the end of January 2024 heading out on road trip I turned on the rear defroster, 5 minutes down the road the rear window exploded sending glass everywhere. When inspecting the broken window I noticed a burn mark on a sticker where the tab is connected to the glass. This could have caused an accident if traveling on the highway. Jeep has been repairing window tabs when they should be replacing the entire window.

My vehicle defrost was on for the back defroster on my way to work as it was one of the coldest days where I live. I work for the fire department and work 48 hrs on. The second day of my shift one of my coworkers noticed the back window broken out on my jeep. Upon looking at what caused it there is burn marks where the rear defrosters touch the window. I initially called the police but they agreed the window was broken due to the rear defroster wires burning the window causing it to break out. Jeep sent out an engineer and is denying all liability. There are TONS of people reporting this on the jeep forums/blogs. I have pictures to prove the burn marks. It appears it happens so often that a jeep sales company -??Quadratec-?? is sold out of replacement rear windows. One guy posted on the Jeep Forum it happened while he was driving 70 on an interstate. Another gentleman posted it happened two times to him as his rear window just broke out. There are tons of pictures on the Jeep blog as well. I have several pictures of mine and it-??s still broken. I-??m due to get it repaired on Monday Jan 29, 2024. I can forward all my pictures if need be.

Jeep dash warning lights will randomly all come on at once. This includes service shifter, service airbags, service braking system, ABS warning, cruise control disabled and many others. When it does this, which is daily, the power steering goes out completely at highway speeds and sometimes curves. This has caused me to nearly hit other drivers head on with my family in the vehicle with me. It has left me stranded many times by not recognizing the key fobs and locking the transmission in park at stop lights. I just bought the vehicle, with 64000 miles on it, in October as my primary transportation and I am afraid to drive it. This has caused me severe hardship and endangered mine and my family's life on several occasions. This problem is extremely common with my model year, as seen on several online forums and Jeep has refused to acknowledge the problem or recall the vehicles. It was purchased from a Jeep dealer, Tim Short of Middlesboro Ky. I can understand wear and tear on vehicles, but this has been an issue with 2018 Jeep Rubicons for years. If this problem goes uncorrected, many people WILL die as a result of this issue. Autos are the only thing I know of that, if defective, cannot be returned for a full refund. Something should be done, since I have an 800 dollar monthly payment and nothing to show for it. Thank you for any help you may provide.

The clutch plate has failed on my 2018 Jeep Wrangler. I brought it into the dealer to take a look at it when I was experiencing the clutch slipping while shifting into first gear and also the "Service Auto Start Stop" indicator illuminating. Once the indicator illuminated, it also prevented by cruise control from working. After the dealer conducted troubleshooting of the issue, they told me that it was due to a safety recall on the clutch plate but that parts were unavailable. This appointment took place on August 4th, 2023. I was told that this issue could lead to a fire, so I have not been driving the vehicle since then. As of October 31st 2023, they still do not have the necessary parts to fix the issue. In the meantime, I've had to arrange for alternate transportation which cost me ~$3,700.

Jeep is aware of faulty cluster packs that operate the dash and guages. They have stated it was a software issue (but the flash did not fix), but as soon as it is out of warranty they now say the cluster pack needs replacing for over $1000. The faulty system, reported all over Jeep blogs, results in a complete loss of gauges, speedometer, temp, etc leaving the driver in an u safe scenario of operation and putting others on the road at risk. This has happened to our other Jeep as well. When we contacted Jeep corporate we were told we would hear something within 24 hours, and never heard from them. This happens randomly until complete failure occurs. This started early in the ownership of the new vehicle.

there is a recall, 19A, that has no fix yet. the "this-might-happen" happened to me. clutch plate hot, hole through transmission, near melted fuel lines. got it fixed, major work $6000. Chrysler won't reimburse me because "there is no fix for the recall yet." that is the point. my car sustained major damage due to the recall issue with no fix. when they do find a fix, the replacement parts that i have now will still have to be fixed. nothing, including 3 weeks rental, covered under extended warranty because it is a recall issue. recall reimbursement documentation not processed because there is no fix. they have been running me around for almost 2 weeks. i am not someone who can drop $6000 without major pain. i paid with what cash i had, financed what i could at 23%, and had to have a friend use her credit card for the rest. i have nowhere left to turn.

Uconnect system started to control the HVAC, Sound, Phone, any other buttons that are available in the system. 8/22/23 I was traveling to my destination with the windows up when I noticed my Uconnect screen starting to click buttons without my input, I attempted to turn it off, but was unable to do so. I pulled over and turned the vehicle off and made sure to open and close door. When I turned the vehicle back on the issue stopped and I drove away. Approximately 1 mile later the music started blasting at full volume and HVAC system blowing hot air (84 degrees) all the way up. It caused me to almost lose control of my vehicle and required me to pull over on the side of the road. I was able to record approximately 10 seconds as proof of the concern. I turned off the vehicle and contacted Arrigo jeep and explained what had happened. They advised me to bring the vehicle in, which I did the same day. I explained what had happened and was advised by [XXX] and a service advisor that this has happened to many vehicles and It can be a software issue or delaminating of the screen. I left the vehicle with them to check. I went online and researched the concern I was having and what the service advisor had told me. Upon further research I found this is a problem plaguing Uconnect system like Arrigo confirmed with me. I was contacted on 8/23/23 by Arrigo who advised me that they could not replicate the problem, and since they couldn-??t replicate it or find any codes there was nothing that they could do. This is a dangerous situation that could have caused me to crash the vehicle. Arrigo Jeep should be responsible for further researching and correcting this issue as soon as possible. There was NO warning that this concern would happen, and the dealer response is unacceptable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2018 Jeep Wrangler.

Additionally, the vehicle lost motive power, and went into LIMP Mode. The windshield wipers also disengaged. The contact was able to veer to the side of the road. The contact was able to turn off the vehicle after several attempts. The contact stated that he restarted the vehicle after 30 minutes, and the vehicle responded as needed. The warning lights were no longer illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed that the failure was related to the computer system. The vehicle was not repaired. The contact stated that the failure had been recurring while driving.
