The engine blew while I was driving on the highway without warning. Several repairs since January and have had the car at just 2 years. Maintenance has been kept. Dealership replaced radiator, head gasket repair, etc. since just February. Car was towed to dealership. 2 holes in engine at the bottom. Dealership claims they don't know why. After researching this particular engine and car, I feel that vehicle has a lot of issues. I don't feel that it is safe. I think a safety recall should be considered.

Vehicle: 2018 Jeep Wrangler Sport Unlimited VIN: [XXX] Mileage at failure: 40,631 miles Issue Date: [XXX] Component: Engine / Cooling System / Head Gasket My 2018 Jeep Wrangler began experiencing overheating issues at approximately 40,000 miles. The engine cooling fan was frequently running on high, and I noticed an increase in coolant loss. The vehicle was taken to an authorized dealership, where a hydrocarbon test was performed and failed — confirming a likely head gasket failure on the driver-side cylinder head. The technician suspected a defect in the cooling system. I was quoted $4,500 just for engine disassembly, before any repairs. The vehicle is now undrivable and is being sent to another independent shop for a second opinion, costing an additional $250. My Wrangler has been properly maintained, and there is no evidence of abuse or neglect. I have attached a dealership invoice and diagnostic notes. This kind of failure should not occur on a well-maintained vehicle with only 40,000 miles. After researching the issue, I discovered that other Jeep owners have reported similar overheating and head gasket failures, particularly in models equipped with the 3.6L Pentastar engine. Technical Service Bulletin (TSB) 18-078-18 Rev A describes cooling system concerns that may contribute to this type of failure. I believe this may indicate a broader defect in the engine or cooling system. Stellantis has not responded to my repeated requests for assistance. I am filing this report to document the issue and request a formal investigation, as this may be part of a wider pattern of early engine failure affecting this vehicle model.

After purchasing seems the vin was updated with information I was not disclosed. The bcm has never worked correctly the instrument panel is erratic and even with a code reader showing P codes there’s no check light. The steering makes the entire vehicle jump over half a road. Blind spot monitors don’t know what to do sometimes they are unavailable, odometer has all 9s sometimes. I did all the checks on the vehicle at the time and what I was given showed I had a 2018 4 door Sahara and that was what I was led to believe. After having issues and getting my registration I started looking at everything more because the dealer registered me as a commercial passenger truck(still don’t know why) but found a report that says Moab/sahara and my seems my vehicles body chasis and motor are all over the place. I’m pretty sure the engine is failing as at one point in one of the reports I found it stated it failed emissions. But the overall worst is that the suspension looks like it came off the titanic compared to the body panels, there’s a lot of welding and rusted or “appearingly tampered” pieces in the chassis and the vehicle seems to be coming apart at every seam. I am currently not driving it because it looks to have sank down to where it could be dangerous I’m pretty sure the suspension, frame, and axles aren’t rated for what’s on it and sounded like something may be coming off at the wheel or axle area last time I did drive it. The vehicle I thought I was purchasing had safety guidelines and there is 2.0 parts, 3.6 parts on this along with random other countries parts. It was bought used “As-Is” but not under the pretense that they assembled it by hand from leftovers. It wouldn’t pass safety standards or emissions in a foreign country much less in the UNITED STATES. I am starting here but will be seeking legal counsel. No longer certain I even have a jeep frame or chassis or just some panels stuck to a rusting timebomb. I’ve only drove like 8,000 miles. Now I’m scared to

The check engine light came on in my car. I was waiting for the dealer to call me to fix it for the 3rd time. I was on my way home when every electrical option on the vehicle turned on- wipers, lights, dash lights, brake- which caused the car to brake- then it turned off and I had no brakes, the car had no steering, it accelerated and I went off the road.

The 3.6L Pentastar engine has a know engine problem with the Cam, valves, lifters. I am a lucky enough to have the same ticking issues as millions of other unsuspecting customers. They was just quoted $6,000 dollars for the repair at our local Dodge dealer for a know defect on this particular engine. This issue should be brought up to US consumer protection and be covered by the manufacturer. My 2018 Jeep has 71,000 miles! The Engine should not have a catastrophic failure this early in its life.

My vehicle’s cooling system continues to develop leaks in the antifreeze line/reservoir. I’ve had it repaired three times, but the problem returns each time, causing the engine to lose coolant and overheat. The coolant reservoir continuously cracks little by little my vehicle has broken down twice due to overheating. During my last oil change my mechanic informed me he has seen this issue and multiple times on other Jeep wranglers. The vehicle is available for inspection The vehicle has not been inspected by of the listed parties No warning lamps the symptoms are the car making a humming noise after driving about an miles, leaking antifreeze as soon as I add it to the compartment. I’m constantly refilling it with antifreeze due to this, and vehicle overheating.

The oil filter housing/oil cooler is made of plastic and every Jeep Wrangler ends up leaking because of it and it should be a recall.

NHTSA ODI 11642571

the vehicle was taken to the dealer because the check engine light was on. we were told the oil cooler was leaking and there was no oil in the vehicle. at no time did the low oil indicator come on. the dealer advised the oil cooler was manufactured as a plastic component and repeatedly would fail causing the oi to leak out of the engine. the engine oil cooler was replaced with a newly designed metal part. the oil cooler failure also caused the oil pressure sensor to fail. repairs totaled $1942.07 for jeep's faulty designed. repairs were made by the jeep dealer. repairs were paid out of pocket and not covered by warranty. the jeep had just hit 100,442 miles when the failure occurred. jeep online forums have repeatedly posted about this problem. jeep needs to recall the faulty design that can cause the engine to leak out all the oil without warning. safety of us and others is at risk because the oil leaks out without warning, other then the check engine light coming on. no low oil or low oil pressure light ever illuminated. same can result in drivers being stranded on the road or result in engine failure.

The 3.6l v6 (mostly in the 2014-2020 wrangler) has a known issue for cylinder 4, 5 and 6 misfires, warping, metal shavings, damaged cams, ticking, overheating etc. My wrangler has had this issue multiple times and the cost to repair it is well over $4000 each time. The first time, my wrangler had 85000 miles and now it has 135,000 miles. The vehicle overheats, starts rough, idles rough, loses power, mpg tanks and its a huge safety issue (I drive my 2 year old son around a lot, as well as my dog).

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).

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.

Clutch - The Sansone Dealer located in Avenel, NJ has informed me that they did not have the part at the time and that I would receive a call. I never got a call so I decided to take the car back to them and now I'm being told they would need to hold onto the car for at least 48-hrs to diagnose the car. I don't understand why when they should be aware of the recall.

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. Chrysler 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.
