The contact owns a 2018 Jeep Wrangler. The contact stated after parking and turning off the vehicle, she saw smoke exiting from the hood. The contact stated she removed her two infants from the vehicle before locating the fire extinguisher she had available in the vehicle. The contact stated the fire extinguisher was broken but was able to extinguish the fire with a fire extinguisher that was provided by a school bus driver that was in the area. The fire department did arrive at the location after the fire was extinguished and filed a fire report. The contact was not aware if the police deputy at the scene filed a police report. The contact stated she burned her right middle finder while extinguishing the fire but did not seek medical attention for her injury. The vehicle was not drivable.

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.

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.

The Jeep was being driven to a dealership to get checked for recalls due to the engine stuttering and stalling, radio and navigation not working, and just not running right. All of the sudden the engine -€˜blew up-€™ and it stopped running. The Jeep was rolled to the side of the road and oil was seen leaking out of a hole in the underside of the engine. Pics were taken. It was towed to a dealership. No inspection has been performed yet to determine what the cause of the catastrophic failure is.

OIl Cooler failure resulting in oil spill onto the transmission and motor housing. Per discussions of JK forums and other associated websites, this is a common issue with the 3.6 penstar motors. It was recalled on the Jeep Cherokees; however, failure to recall on the JK models were not available. Furthermore, most tech are stating when changing the oil filter, over torque can cause the seal to break or housing to crack resulting in leak. On manay forums, the JK ranging in years for the oil cooler issue is higher than normal.

The vehicle intermittently fails to shift into gear when started. This also happens intermittently while driving (when stopped the engine turns off while the brake pedal is depressed. When the engine restarts to go forward it behaves as if it is in neutral and won't engage.) Additionally, on occasion, the instrument panel fails to function while in operation. There is a blog thread on this issue as experienced by others: https://www.jlwranglerforums.com/forum/threads/service-shifter.24255/ ***Note, the date listed below is when we first began experiencing this issue. This is an ongoing issue which is experience 5 or more times per week. The vehicle has been in and out of the shop without resolution. The cost is out of pocket. The vehicle is currently sitting at the dealership shop considered "unsafe to operate" while we wait on a solution.

Several messages display simultaneously on and off as the vehicle is in motion which results in power being lost, then restored in a matter of minutes which are critical when traveling in traffic or on the interstate. Steering and brakes are the first to go, but the car remains operational. The gauges display as if the car is stationary with check engine, brake, start stop disabled, traction control and many other lights displaying in error as these things are happening.

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.

Multiple times the check engine light, air bag lights, powertrain light have went off. I took it to the dealership, they said nothing was wrong and reset the lights. The last time this happened, all power went out on my Jeep Wrangler. I pulled it to the side. Sat for a while and drove 20 home. I called the Jeep dealership and they inspected my car. 160 warnings were on the electric scan. The mechanic called Chrysler--they charged me almost a 1,000 to fix something in the steering column. I have no warranty as it has been over 3 years. I took my car back and the dealership mechanic said he wasn't sure if he fixed it and I should call Chrysler. We did. My case # is 82498233. They said they couldn't do anything about it. Since then, my car keeps losing power while I am driving. I pull it over and sit and then it starts working within 15 minutes. No one knows what is wrong with it. It is a 2018.5 Jeep Wrangler. I am teaching my son to drive on it and it is very scary.

The frame bracket for the engine mount has a vertical slot instead of the traditional round hole. This allows the engine to climb out of the mount in case the cross bolt gets loosened even slightly. I discovered this flaw when my engine started twisting and the output yoke on the rear driveshaft was rubbing against the fuel tank. Untreated it could have ruptured the gas tank. The enclosed photo shows the main engine mount bolt having pulled out of the mount and sitting above it. Essentially at this point the engine is not connected to the frame.

1. Engine 2. Yes. I was on a major highway when the Jeep wouldn't go above 10 miles per hour and almost causing me to get rear ended. 3. I had it at the dealer at least 4 times, they can't find the problem. They replaced ABS controller, still they can't find the problem. 4. The vehicle was inspected by the dealer, not even sure how it passed state inspection. 5. Every warning light came up on the dashboard. The problem started in November 2021. The last incident happened on the night of 2/19, this time the vehicle would go pass first gear...I was driving 10mph.

I was in my car at a gas station and the car had shut down with ABS light, check engine light. The car would not start up with push to start. The shifter also was locked into place when the car eventually ended up starting. 5 mins later the car finally started up and all the of the warning lights/messages went away. I received an oil change + inspection from a dealership and nothing was found. This same problem happened again in a parking lot, (ABS, check engine, car not turning on) and I took my car to the dealership for service. They performed an inspection and I was told the ABS module needed to be replaced. About a week later I picked up my car from the dealership after they told me they fixed the issue and my car was good to go. THE SAME DAY, I had the same problem except this time it was significantly worse and extremely dangerous for myself and others. This time, WHILE driving my "serviced" vehicle, the ABS light, check engine light came on, dashboard stopped working, and the steering wheel also had locked while DRIVING and I was unable to turn. I was extremely terrified and I immediately pulled the car over. After multiple attempts to start the car (same issue as before: car would not start, ABS/check engine light) I promptly took the vehicle to the dealership again. The dealership is charging me again for another inspection, hours after their service? It seems that they are using this as an opportunity to make money, rather than actually fix the issue with the vehicle. This should not be about money, this is EXTREMELY DANGEROUS. The service the dealership has provided not only endangered my life, but the lives of others around me. I am extremely fortunate that this did not happen on the freeway. The dealer did not fix the problem, and in fact made the car dangerous with some of these new issues, the steering wheel locking up and the disabled dashboard. The part they replaced did not fix my car and put me, as well as others in a DANGEROUS situation.

Was driving on the freeway with my wife and five yr old son when we heard a loud pop underneath our 2018 Jeep Wrangler and instantly saw a trail of smoke behind us. We immediately pulled over to find transmission guild gushing from underneath with tons of smoke as well. We were hoping the smoke was probably just from fluid on the manifold but we small flashes of fire starting at the transmission and clutch area. I quickly grabbed my son sitting in back and we jumped over the concrete barrier on the side and ran away from the Jeep as it quickly became engulfed. It still had the temp tags having only had it three weeks. It was a 2018 with 15K miles.

While driving, the auto start/stop function will disable and a message on the dash pops up that says 'stop/start unavailable. Service start/stop' and a yellow a with an arrow around it will light up on the dash. This happens intermittently but happens every day. While at a red light, my Jeep shut off completely while I was still in drive. The service message as previously stated appeared, along with the yellow a and arrow. I had to put my Jeep into park and restart my engine. The system message and a continued to display. The vehicle has only shut down completely one time, how ever that still is a safety risk for myself and other drivers. Vehicle has been at the Jeep dealership for roughly two weeks trying to determine what is wrong.
