Under hard acceleration, like passing a car on the highway, the vehicle goes into limp mode which has nearly caused me to wreck 4 to 5 times due to being unable to accelerate. Once I pull of the road and restart limp mode goes away but the engine light stays on. The dealership says that the wiring harness is the issue. The vehicle has codes popping up about torque management. I would like for this to be fixed free of charge due to the wiring harnesses being an integral part if this vehicle.

First my power windows wouldn't work while driving, I pulled off the side of the road and turned the car off and that temporarily fixed the issue (it has happen twice since). That same day I was driving on the interstate using my cruise control set at 70mph and the traction control light came on and the cruise control shut down and disabled itself while keeping the cruise control light on and not allowing me to turn off or reset the cruise control. (these lights went out the following day). A couple days later while driving, a warning of the rear drivers side turn signal being out came on (this comes and goes now almost daily). Last night while my Jeep was parked in driveway of my home the headlights and dome light started coming on randomly. The headlight and dome light switch where both in the off position and the keys were on my kitchen table inside the house (this is continuing to happen in the parking lot at work also). When I got in it to go to work and while idling the hazards lights would randomly blink twice and then stop, wait a couple minutes and happen again. While sitting in the parking lot at work I noticed that when this happen the headlights are also turning on, they turned off after a minute or two, and then it happens again. It is a rainy day but bright enough that I could not tell if the lights were randomly going in and out while driving. Regardless this is turning in to a serious safety issue and it seems to be all too common with these Fiat-Chrysler vehicles.

The contact owns a 2012 Jeep Wrangler. While driving various speeds, the headlights turned off independently without warning. The contact had to continuously turn the headlight switch in order to have visibility when the failure occurred. The contact also stated that the turn signals would not operate and the windshield wipers operated independently when the vehicle was started. The contact had to repeatedly turn the windshield wipers on and off for them to stop working. The contact called scott robinson Chrysler Dodge Jeep Ram (20900 hawthorne blvd, torrance, ca 90503, (424) 299-8800) where he was informed that the part needed to repair the vehicle would cost $1,300. The manufacturer was notified of the failure and referred the contact to NHTSA for assistance. The vehicle had not been repaired. The failure mileage was 6,500.

Vehicle stalled while in motion on a highway. This has been a consistent issue for the last several years. I believe it first occurred in 2016. The vehicle will just stall on a city street, in a residential area, or even on the highway. Fuel was not related as it has happened on a full tank of gas or a quarter tank. It was taken to the Jeep dealership on multiple occasions (that has been documented) because of this dangerous hazard, and they were not able to replicate so it was never fixed. I even showed them video evidence 3 times. The vehicle just stalls randomly while driving (in the middle of high speed traffic). The RPM would just go to zero, and when trying to start the car back up, it would try to crank, but would not start. The car would have to be turned off for 5 minutes and then the car would eventually start again. This would occur at least 1/month for several months. The Jeep dealership replaced fuel pump, and checked other components as the engine light never turned on, and they could not find the resolution to this issue. This is a highly dangerous problem and seems to be very common among this model year Jeep, and Jeep continues to claim no fault. Someone could die if their car stalled on the highway with cars going 70+ mph. An experienced driver may be able to maneuver, but certainly an inexperienced driver would not. This vehicle was intended to be for a teenage child, but I could not knowingly give this to them having this unresolved issue. After much research, I believe it is a faulty or defective crankshaft position sensor, but Jeep refuses to acknowledge this and continues to say this is not the issue, yet the car has continued to stall on various occasions still. They should be liable for any serious injury or death that may potentially occur! I will be taking this vehicle to be repaired elsewhere after my own research and troubleshooting.

The contact also stated that the windshield wipers did not work and the power door locks worked intermittently. Also, the security alarm also sounded while the vehicle was being driven. The contact took the vehicle to larry H. miller Chrysler Jeep Dodge Ram sandy (10905 auto mall dr, sandy, ut 84070, 866-677-2319), but the cause of the failures could not be determined. The contact was referred to accuracy automotive (4036 S main St, murray, ut 84107, 801-266-3609) where it was diagnosed that the totally integrated power module was defective and needed to be replaced. The contact was given an estimate for the cost of the repair. The manufacturer was notified of the failures. The vehicle was not repaired. The failure mileage was approximately 83,000.

All the electronics in my steering wheel went out, the horn stopped working, and my airbag no longer works. Some of my warning lights on the dash even stopped working. The fm/am radio also no longer works. I took it to the dealership and they said my clock springs went out. I am very worried about my airbag not deploying in a crash. None of these work, whether the car is moving or stationary.

Sway bar light and other indicators flashing because of water entering the electronic sway bar disconnect box in front of the sway bar, under the front of the vehicle in a non-waterproof containment, causing multiple shorts. Common issue in 2012 Jeep Wrangler rubicon unlimited 4X4 because of poor design. This happens when driving in heavy rain, while driving if you hot a large puddle water splashes up in to the box shooting it out.

Lightning bolt symbol and check engine light come on while driving. Vehicle goes into limp mode and starts running roughly. If turned off and allowed to sit will start up again just fine. Check engine light typically turns off after a couple more trips and runs just fine until it randomly does it again. Has been sometimes minutes, other times weeks between episodes. Have had accelerator position sensor replaced, throttle body replaced, and wiring to throttle replaced. Keeps happening. Has happened when vehicle is parked, sitting at light, normal driving, and while driving at highway speed.

While driving my 2012 Jeep Wrangler unlimited recently, all of a sudden my check engine light comes on & shortly after my ABS & traction control lights go on as well. I've had the car checked twice & no one can seem to give me an answer on what the problem is. They've went off since but came back on a day later. It's beyond frustrating especially when I see so many people with similar problems yet no recalls? for the cost of these cars, I can't understand why there's so many with issues. Also while I'm at it I should note that my heating & defrost completely stopped working. I live in upstate NY & my mileage is currently 109K

Driving down the road when suddenly all the lights started flashing, radio flashed and then the Jeep started to loose power. Pulled over, put in park and turned it off. Exterior and interior lights were flashing. Clicking noises where coming from the tipm even with the key off. Everything was locked up once it was put in park and wouldn't unlock to tow. The only recourse was to unhook the battery and try to reset everything after waiting for about 20 seconds. I hooked the battery back and was able to drive it home. This is the second time this happened however the first time was in park and everything went haywire. Was able to restart w/O disconnecting the battery. It is getting worse. We are looking at a $1000 repair bill. We are hesitant to drive it.

Stationary vehicle starts when I open the door without having key in ignition. Stationary vehicle engine fails to shut off when I turn off ignition and remove key. Anti-lock brake system locks up brakes while vehicle is standing still and will not move under any throttle amount because the brakes remain locked up. Vehicle factory alarm turns on and off randomly when drivers door is opened. Windows roll down by themselves while vehicle is turned off. Air conditioner blower (can't say if compressor keeps running or not) randomly shuts off while driving down the road and comes back on a couple of minutes later. Cruise control will not accept speed set but then turns 5 minutes later whether you wanted it to or not. Everything points to the tipm but even with 10's of thousands of complaints Fiat/Chrysler still insist there is no Wrangler tipm problem, and U.S. government oversight groups refuse to do anything about it. (when did this happen date is just the latest occurrence of an ongoing serious safety issue that Fiat/Chrysler refuses to acknowledge..

The contact owns a 2012 Jeep Wrangler. While driving for approximately 15 minutes, gray smoke emerged from the engine compartment. The contact pulled over and opened the hood to find the harness (that goes around the battery) engulfed in flames. The contact extinguished the fire with water.

The manufacturer was not notified of the failure. The vehicle was not repaired. The approximate failure mileage was 48,000.
