The radiator is poorly built and leaks, I have had mine replace several times by the dealership This is dangerous because it causes overheating in the engine which can cause hose to bust and engine to seize up. The oil filter house is engineered incorrect and all of them have been breaking causing oil to leak which again, ruins other components in the engine because of loss of oil. Its dangerous because the oil that leaks down through the outer portion of the engine, through to the sides and leaks over the bottom of the transmission onto the ground which is: 1. Environmental hazard- oil leaking causes water pollution, soil contamination, harm to animals and plants 2. Leaking oil is a FIRE HAZARD and safety issues for other vehicles causing slippery conditions for other vehicles 3. Causes engine damage and eventually failure I urge you to obtain the records of all the repairs jeep dealers did both under warranty and past the warranty dates. Your team will see what an issue this is and the 10000000s of Jeep Wranglers that have had these unsafe problems with the OIL Filter Housing and Radiator issues during and after the warranty. Jeep / Chrysler have created a deceptive way for revenue by allowing Jeep dealers to charge the customers for faulty engineering so they can gain profits in repairs that is the Manufacturer's own fault thereby gouging Jeep Wrangler owners.

while driving at an 50 MPH speed, the check engine warning light illuminated and flashing continuously. The vehicle was not in drivable condition since it was unusually vibrating while either standing or driving at very low speed. The vehicle was taken to an independent mechanic, who determined that there was a cylinder #2 misfire, and that the valve, cylinder head or crack on the casting causing this issue. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 75,000.

2015 original owner, developed misfire cylinder #4 P0304, replaced coils, plugs, injectors, harness on that side. Misfire still present, noted others have reported issues with cylinder head (valves, cams, rockers). Engine has a slight tick, found no recalls on NHTSA site except for 2014 versions with same engine for this exact issue.

- Atascosa, TX, USA

The engine has a known failure causing a cylinder misfire that is resolved by replacing the cylinder heads. This is a known issue to FCA and caused an extension of the powertrain warranty for the 2010-2014 models but does not cover later engines, that are still experiencing the same issues. The covered years needs to be extended to 2018 or beyond and all out-of-pocket repair costs should be refunded to the consumer.

My Jeep has the pentastar 3.6l engine and has recently developed what is known as the -??pentastar tick-??. This is caused by a design flaw with the valvetrain, specifically the lifters/rocker arms that causes excessive wear which leads to the tick, which may then lead to engine failure and loss of control. This is a very common problem with the 3.6 engine and FCA should be held responsible for the safety recall. FCA has already acknowledged the problem on 2012-2014 engines, and extended the warranty, but not on the later engines. Please look out for the consumer and hold them accountable.

I was driving and all the dash board lights came on and it started warning beepings then it would not go over 35mph The ABS module was affected because it has a defective eyelet in the TIPM Module wiring connector that allows water to seep in I had a level 2 system testing done to find the defect. Jeep is aware of the problem because when I tried to order a new ABS module I was told it was not available because they are re-engineering it.

Check engine light came on for misfire in Cylinder 4. Jeep lost power when on the road

- Franklin, TN, USA

The traction control light and ABS dash lights will come on and the vehicle will jerk and bog down while driving. It is very dangerous and needs to be fixed. I looked on jeep forum to see if I could see what's going on with it and there were a bunch of jeeps that have the same problem.

- Foley, AL, USA

Cranked my vehicle from a cold start and it started running very rough. Had a mechanic put a code scanner on it and it read cylinder #2 misfire. I have been told this is very problematic with the 3.6 pentastar engine and a costly repair. If this is a factory defect I would like to be informed about any and all considerations to which I am entitled to. Thank you very much.

I have just replaced the Engine oil filter housing on my 2015 jeep wrangler unlimited rubicon for the fourth time the first three replacements were at East hills jeep on Long Island n.y the fourth repair was at Willis ave repair and diagnostic in Albertson N.Y at a cost of $859.33. Ongoing problem with thousands of other jeeps owners reporting the same issue. during the course of these breakdowns, I-??ve had to have my vehicle towed to the repair place twice as the oil had drained out of the vehicle causing fatigue and overheating to the engine. I currently has 95,000 miles on my jeep witch is well taken care of and serviced at the East hills jeep dealership. My concern is future damage to my engine due to the extreme temperatures caused by the lack of oil and overheating due to this defect. How is it that the manufacturer is not held responsible for an obvious defect in a crucial engine component causing multiple replacements to thousands of similar vehicles.

What component or system failed or malfunctioned, and is it available for inspection upon request? The component that failed is the oil filter housing/assembly. It was changed out by the Pep Boys I do not have it on hand but upon research it appears that this is a known issue on the 3.6 and the 3.2 Chrysler Pentastar engines. Mopar made this part out of entirely plastic and it is now failing on a ton of vehicles. The replacement parts are all made out of metal/aluminum. Safety: this not only put myself at a safety risk but also puts other motorists on the road at risk. Not to mention the environmental safety that this can cause. The plastic part contains the oil filter for the engine. After time it warps and fails causing cracks and seal leaks that allows oil to drain out of the engine, onto the transmission manifold and all over the ground/road. There is no warning for this, one day you will walk out and find your vehicle bleeding all of its oil all over the pavement. This could happen to anyone at any time. I would hate to be on a motorcycle driving behind a Chrysler engine when their engine decides to fall apart and slick up the expressway with motor oil. Jeep/Chrysler knows that this is happening, they know it-??s a problem because the replacement part is made of metal instead of plastic, and they refuse to do anything about this even under warranty. This is a part that is NEVER supposed to go bad on any cars, this is NOT a wear and tear part. I would like to see them held accountable for their (lack of) actions.

At 134,000 miles the engine developed a loud ticking. My garage reported that rocker arms, cam shafts and heads needed rrplacement. They recommended that Jeep dealer should be performing the work so that I might have a parts warranty. The dealer reported back that the work would be extensive and recommended engine replacement with a $13,000 estimate.

Faulty oil cooler. 2 different mechanics reported this as a common problem with 2015 jeep wrangler. Due to the way this model was made, the oil cooler is too close to the hot engine making it faulty. As well as the parts around it all have to be replaced. I've been told not to drive the vehicle due to fire hazard. The estimates I've been given are $1400 and up. I've also read many complaints about this same issue, same vehicle, same year, on several different web sites.
