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.

My Jeep Stalled on me in the middle of the street at Night. All of the lights dimmed out including my Emergency lights, I couldn’t put into Neutral or turn it on I had to get it towed Home. Both batteries replaced it turns on but stalls. Could be the alternator?
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.
Coolant reservoir cracked to allow coolant to leak at 5800 miles.
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.
I was driving on the interstate highway when I heard a loud pop and saw an arc flash and pulled to the side emergency lane. I then saw flames dripping from my jeep and the entire front end of the jeep went up in flames and caught fire.
Began smelling coolant (sweet smell), although could not find leak. At 15,600 miles (may 2020), vehicle was brought to jeep dlr for service. Found small cracks in the plastic portion of the radiator. Now, at 18,600, the sweet smell is back. Will need to take it back in to jeep dlr again.

While braking the jeep, the braking system didn't override the engine. Jeep kept going in drive instead of stopping. I had to put it in neutral to get the jeep stopped. I almost went into a busy highway in front of truck going 60mph. Could have been hurt or killed.
The vehicle does not crank and have to wait 10 to 15 minutes for it to start.it happened four times in a week. There are lots of trends online with other jeep wrangler owner with the same problem. No diagnostic error when using obd scanner.
Radiator leak (failure). Jeep dealer confirmed and repair is in process.
Audible ticking coming from engine compartment

I will like my money back if the no solution.
When traveling on highway at 50-70 MPH and hitting a bump, the front of the jeep begins to shake or wobble very hard back and forth. The only way to stop it is to hit the brakes quickly and hard, making driving very unsafe - especially increasing the danger of getting rear ended. It has been in the shop 3 times to correct this issue to no avail. Engine light also goes on and off repeatedly.
My five week old manual jeep wrangler jl with approximately 1500 miles on it was in motion travelling westbound on a 55 MPH road when the incident occurred. The jeep had been in motion for approximately 1/4 of a mile when it was shifted into third gear and part of the transmission fell off of the vehicle. When shifted into 4th gear, again more parts fell from beneath the jeep. Immediately following the gear change the lights on the dash all lit up and black smoke and flames were seen simultaneously on the front passenger side of the vehicle. The jeep was immediately pulled over and stopped on the side of the road where 911 was called. The firefighters found pieces of the transmission hundreds of yards from where the vehicle became engulfed in flames.

Vehicle seems to rev up on its own/gas pedal feels like it sticks
When I first turn on the heater on cold morning, a maple syrup smell like antifreeze comes out of the dash vents. My coolant overflow tank looses about 1/4" coolant in 2000 miles. I believe there is a pin hole leak in the heater core. The dealer did a pressure test, but the leak must be too small to detect. The smell is nauseating and I understand antifreeze vapor is toxic..
Drove into the gas station, put my jeep in park, put the emergency break on, turned it off and proceeded to fill up the tank, I did not top the tank off, got back in my jeep started it back up, engine started fine, released emergency break put jeep in drive put foot on gas to proceed out of the gas station jeep pulled out of the gas bay and I drove forward slowly, while turning left out of the bay. I drove forward with my foot on the gas about 20 feet. All of a sudden the jeep came to a stop and shut off while still in drive. I would press on the gas pedal to move forward and nothing would happen it just remained stationary.. All electronics still worked in the car. I put the car in park, turned on my hazards turned the jeep off and then back on, and engine was not starting. Turned it on and off 3 more times and finally the engine started back up on the 4th time and I was able to drive away. This has not occurred again, but I have not driven it other than 20 miles back home where it now is sitting waiting to go to the jeep dealership.

Operating vehicle in 4 low mode, descending a modest grade off road, experienced unintended vehicle acceleration when foot was off gas pedal
2018 jeep jl (all white) has paint turning yellow from excess heat in the engine area. Jeep has less than 300 miles on it. Areas affected include front grill, right front fender. Primarily on driver's side. Not an isolated incident - see https://www.jlwranglerforums.com/forum/threads/bright-white-grille-turning-yellow.6394/ .
While operating the vehicle, I encountered severe tightness from the steering wheel. Disabling me to turn left or right, typically on the highway while accelerating. If I was to turn the vehicle's steering wheel for a slight curve or turn the vehicle would remain straight making the vehicle impossible to make the appropriate adjustment. Vehicle was pulled to safety for a reset ( turning off the engine for 5 mins before restarting). Upon accelerating the tightness of the steering wheel began, eventually causing the engine to stall.
Vehicle driven fo approximately 30 minutes with no apparent issues. Average speed about 40 to 50 MPH. Driver smelled a concerning odor, pulled into a parking, got out of vehicle and noticed a flame. She called 911and vehicle became fully engulfed. Vehicle is a total loss. After some research, it appears this is an issue with jeep.
Electrical issues incl but not limited to: gauge readouts incorrect, ECM not allowing proper shifts. Engine problems with the valve lifters making noise and broken.
Vehicle stalled in highway, stop and go traffic for no reason and was extremely hard to restart. A few days later, the radio and backup camera went out and came back an hour or so later. The radio, which controls all electronics and backup camera, went out again. Dealer replaced some sort of interface for the infotainment system (radio) on 07/30/18. Then vehicle stalled again in highway, stop and go traffic on 08/03/2018 and was difficult to restart. Then, on 08/09/2018, a battery charge warning came on and they replaced the alternator. What is even more troubling, is these very problems are all over the internet. All work has been covered under warrantee but I have wasted the better part of two full days driving to/from the dealer or waiting in the waiting room. I have filed a complaint with fca (jeep). It appears as though the electrical system jeep engineers have designed for these wrangler rubicon jls is flawed to say the least.
