general problems of the 2018 Jeep Wrangler - part 2

I have put thousands of dollars already into the motor because my Jeep continually overheats and looses coolant. Its been in the shop countless times over the last year with the same issue. I was told it was the head gasket with is a $3k job. I took it to get a second opinion and this shop just completed the same repair on my exact vehicle. It wasn't the head gasket. He said the cylinder is cracked and it would need to be completely replaced. $10k. That it is a factor defect and that Chrysler has been aware of the issue but is currently not doing anything about issue. He said they extensively searched the cylinder head and could not see where the crack was but Chrysler's recommendation was just replace the cylinder because that is where the issue is. I cannot afford to spend $10k on a repair. The vehicle is not even that old to have this issue, it is a 2018. Chrysler told my mechanic that it was a factor defect, a malfunction in the actual part, but that a recall hasn't been issued yet.

Told I need a new engine, never over did anything. An, used only as a daily driver. No extreme use.

Head gasket failed due to a manufacturing flaw in the engine block. Coolant leaked internally from the cooling passage into cylinder one causing a hydro lock. No external leaks. Engine is damaged beyond repair.

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. Chryselr 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.

The oil housing unit has cracked and has to be replaced. The Jeep is currently in the shop and they discovered that it is made of plastic and cracked. I had oil pouring out when I took it to the shop. After doing some research, apparently this is a problem with Jeeps.

The sensors, in particular the blind spot warning, randomly light up and stay on until the vehicle is turned off. Radio and navigation system randomly shuts off, and check engine light goes on and off randomly. While driving at night, my entire dash flashed a red warning that there was no oil in the vehicle. I immediately pulled over at a gas station. It was dark, I couldn’t see, and it was 2am in a town I was unfamiliar with. I added 1 quart of oil ( I couldn’t really see the dipstick). The warning light went off, and the check engine light came on. I went 30 minutes to my destination and had the car towed to the dealership the next day. They said it was an O2 sensor, and that there was too much oil in the vehicle so they drained it and did an oil change. I picked it up, drove less than 5 miles, and the check engine light came back on. I immediately returned to the dealership. They had it for several days before telling me that I had to replace the catalytic converters (2 of them) because I had overfilled the oil. They deemed it my fault. Since then the sensor problems continued, and the check engine light would randomly go on and off. Now it’s at the dealership again because it was leaking oil after an oil change. The dealership, and inspector from my extended warranty are saying that it has a blown engine because there was too little oil (in spite of no sensor going off warning that the oil was low). Extended warranty inspector wants me to authorize a complete engine tear down for further inspection ($7000) and the dealership says I should just replace the engine ($11,000).

All the lights on the Jeep came on. Locked up nearly had a wreck. Had to be towed. Now dealership is saying its the motor. Everything shut down. This is not the first time the Jeep has shut all the way down. This is very dangerous. We had replaced the starter, and battery and spark plugs and box.

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.

Track bar bracket separating from frame. Coolant leaking into engine. This has been going on for about a year since we bought it. Dealer just says there’s nothing wrong with it. But we have been taking it to mechanics since we got it.

All lights on dash light up while driving or in park, no power steering, all displays flickering, can not move vehicle. While in park, can not engage shifter, if I turn off vehicle while it’s on the “fritz”, vehicle might not start for some time (15-40 minutes), this has been on going since 11/22, three visits to dealership, two at an independent shop. Dealership claimed the couldn’t replicate issue/“concern” vehicle is simply not safe. I’ve recorded many videos documenting these safety/vehicle issues. It’s been nearly 6 months of trying to get a reputable diagnosis, repair and answers. I hope this isn’t a scam? I truly need help.

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.

Start and stop button light came off and vehicle stopped drive. I’m the last 2 years I have to replace battery 3 times.

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 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.

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.

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.

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.

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.

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. . Read more...

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.

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.

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 contact was concerned because if the primary battery was disconnected the second battery would still provide electricity to the vehicle. The contact stated the secondary battery short circuited and the vehicle was not able to be started. 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. The failure mileage was 40,000.

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.

Failure to start, randomly when vehicle is stationary. Visible pertaining component parts such as battery, ignition switch, starter and voltage all in good order. After 30 minute waiting period car will start. Steering wheel movement when exiting vehicle appears to trigger problem, quite often. Has occurred 8 times in 4 months. Dealer showed no error codes.
