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.

I have experience a complete loss of control of the vehicle on both highways and streets that are bumpy due to dips, potholes, rough conditions due to the road. I received a misfire on cylinder 4 code P0304 and was told my vehicle isn-??t covered for any recalls, but see that this is a common issue in 2013, 2014, 2015, and 2017 models. I want to know if any recalls or lawsuits are going on because my dealership informed me there aren-??t any and it would take a week to even be able to diagnose the issue.

My Jeep has a left cylinder head failure at 78k miles. Jeep forums are full of discussions regarding this issue. The dealer says there is no reason for the failure and that they have seen this before. Jeep says my warranty is expired so I am out of luck. This is my third Jeep and the first time I have had any issue mechanically. This failure is not from normal wear and tear. It's very frustrating that no recall on this obviously faulty engine part exists.

I had a 2015 2 dr Jeep Wrangler Willy's edition. In march 2023, after sitting cold in the driveway for 10+ hours, it spontaneously combusted. It was very obviously an electrical fire based on the smell alone. It appeared that the most damage was in the area of the battery and fuse box. Vehicle was completely totaled and I found many reports online of similar issues, including many wranglers that were completely totaled after the fire. There is no official acknowledgement of this recurring issue. The fire caught so fast, if I had not been parked in the driveway faced away from the house, I might not have a home either. Insurance did not do an investigation into the cause of the fire.

My truck was making a loud clicking noise and kind or rattle. I took the vehicle in to be serviced. I was told that I needed to have all lifters, rockers and cams replaced. That these items being worn out is a known issue with Jeep Wranglers but there has not been a recall for this issue. The dealership replaced those items the camshaft exhaust, camshaft intake, arm valve, tappet valve lash, gasket cylinder and gasket intake. As stated by the dealership having to replace the lifters, rockers and cams is a known issue. Most people just trade the truck in. I would like to know if this is a known issue why has there not been a recall for this? Also because of the cams this caused the cylinder misfire in the engine.

I have had the oil filter housing crack two times costing over 1 grand each time to have replaced by a shop. The lifters and rockers have gone out on each side of engine now with not even 91k miles on vehicle. Drivers side had 62,000 miles and then the passenger side had 91,000 miles on it. Maintenance has been done on time and not over due.

Check engine light came on. Took jeep to dealership - indicated that the left side cylinder head needed replaced, not placing would cause extensive damage. The vehicle had 65779 miles on it and is in excellent condition, there was no reason for the engine to have such significant problems based on usage. Learned this is a faulty issue and that Jeep is aware of it, although no additional warranty or recall was provided. I was paid over $3,392 to get the issue diagnosed and repaired.

No crash or injuries. My Jeep only has 45,000 original miles and it is leaking oil from the oil cooler. I researched and this seems to be a very common issue with the 2015 3.6 L Jeep Wrangler. It cost over $1,500 to repair. As the other gentleman stated in his complaint, I feel this is a major issue that needs to be addressed by Jeep. See the other post below for further detail: I OWN TWO JEEP WRANGLERS, A 2013 AND A 2015. I HAD THE 2015 REPAIRED AT A COST OF OVER $1,000. NOW MY 2013 HAS DEVELOPED THE SAME PROBLEM; TO WIT, THE OIL COOLER/ OIL FILTER HOUSING CRACKS ON CHRYSLER 3.6 ENGINES AND THE OIL IS SPREAD ONTO THE EXHAUST PIPE WHICH HAS THE POTENTIAL OF CAUSING A FIRE. IF THIS IS NOT DISCOVERED, THE OIL WILL SPREAD TO THE REAR TIRES WHICH WILL CAUSE A TRACTION OR BRAKING HAZARD. CHRYSLER HAS NOT MODIFIED THE HOUSING AND WHEN YOU REPLACE, IT IS REPLACED WITH THE SAME PART THAT WILL FAIL IN THE FUTURE. CHRYSLER HAS TO KNOW THAT THIS PROBLEM EXISTS BY THE # OF UNITS THAT THEY HAVE SOLD, NOT TO MENTION THE THOUSANDS OF UNITS THAT ARE SOLD ON EBAY AND AUTOMOTIVE PARTS STORES. THERE SHOULD BE A RECALL ON THIS SITUATION BEFORE PEOPLE ARE INJURED OR KILLED.

Our temperature gauge says it-€™s overheating but it-€™s not overheating. We-€™ve had the radiator replaced twice. We-€™ve had it at three different places to take a look at it, we had the dealership look at it and says they can-€™t find anything. But it keeps losing coolant. This has been going on for the last 6 to 9 months can-€™t drive the car more than a few miles.

I own two Jeep Wrangler, a 2013 and a 2015. I had the 2015 repaired at a cost of over $1,000. Now my 2013 has developed the same problem; to wit, the oil cooler/ oil filter housing cracks on Chrysler 3.6 engines and the oil is spread onto the exhaust pipe which has the potential of causing a fire. If this is not discovered, the oil will spread to the rear tires which will cause a traction or braking hazard. Chrysler has not modified the housing and when you replace, it is replaced with the same part that will fail in the future. Chrysler has to know that this problem exists by the # of units that they have sold, not to mention the thousands of units that are sold on ebay and automotive parts stores. There should be a recall on this situation before people are injured or killed.
