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.

The contact owns a 2018 Jeep Wrangler. The contact stated that she was never informed nor saw in the owners manual that the vehicle was equipped with two batteries.

The vehicle was taken to the napleton Chrysler Jeep Dodge Ram (1460 E osceola pkwy, kissimmee, fl 34744, 407-288-8243) to be diagnosed. The contact was informed that the batteries needed to be replaced to correctly diagnose the failure. The contact was informed that the manufacturer was contacted and informed of the failure. The contact was informed that the batteries were available for purchase at the dealer at a cost of $800 for both batteries or could be purchased at the local parts store.
