The thermostat housing has coolant residue on it and is cracked. This seems to be a very common problem with these Jeep. This part is not a part that can be broken the only reason something goes wrong with it is that it is defected. Mopar should be replacing these parts.

My Jeep has less than 21,000 miles on it. I brought it in to the dealership for a coolant leak. They haven't found the coolant leak but they did find an oil leak from the oil cooler. This is the second oil leak from the oil cooler. Parts are on back order, I was told this is a frequent and common problem. They have not found the source of my coolant leak. This car is gently driven by my wife and is unmodified in any way.

The oil cooler under the intake, the Jeep has 68K miles on it, needs a third oil cooler, the dealership refuses to cover them under warranty, this has been an ongoing problem since the first year I bought the Jeep brand new. Every time they crack, out of the blue, no warning, the driver is stranded on the side of the road with six quarts of oil all over the motor, trans, exhaust and ground.

The contact owns a 2014 Jeep Wrangler. The contact stated that there was evidence of an oil leak emitting from the oil filler assembly. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 49,000. The VIN was not available.

Oil filter adapter, oil cooler, not sure on correct terminology. Part number 68105583aa to be specific. Just got normal maintenance and multi point inspection done and 2 days, 128 miles later smoke started gushing out from under my vehicle. I was driving to get lunch, got out and sure enough oil was profusely leaking out of the bottom. Drove home immediately and parked it. Had to wait until Monday to try and drive it to the dealership. Started her up and within 5 minutes had a puddle the size of a tire underneath of oil. Managed to get her to the dealership without issue, but my system was telling me I had 0% pills like remaining. Oil had been leaking out from on top of the engine worrying me of a potential fire hazard but I managed to get it to the shop. Apparently this part is not covered under warranty, but this is a widely known issue with 2014 models specifically all Chrysler made vehicles with this engine. $500 fix is not fun when it's a known issue by the company who on 2015 models fixed it and never addressed or warned 2014 model owners.

On 12/04/2016 I was driving on the freeway at around 80mph when a load explosion stopped my engine. I immediate stopped as smoke started to come inside the cabin. As soon as I exited the vehicle I noticed a big fire under the car and insure the hood. I was able to put the fire out using 3 fire extinguishers. This really could've escalated quickly. I noticed a big hole on the side of the engine. Looks like it threw a rod since the oil pressure was low. Probably due to faulty oil filter mount. The exact reason for the engine failure and subsequent fire hasn't been determined yet as the dealer will ot look at it until Chrysler sends an investigator to determine the cause. Chrysler will not send an investigator and is asking for the dealer to look at it. It's been over 10 days and nothing has been done. So far, neither party has taken the issue seriously. The car is still under warranty.

I've noticed for the past few months like leakage on the ground but have yet to pinpoint the exact location. I took it to the Jeep dealership and asked if they have had any issues with leaks and danced around the question and said I would need to leave it for a mechanic to look at it, I asked if my warranty was still valid and the had ran my VIN and said it was expired......which is puzzling cause I have around 30K miles on it. So I still have a mystery leak and reading up on different forums seems to be on ongoing issues with cooling oil lines or oil filter adapter, oil cooler.

3,6 oil filter adapter leaking. Have 38,000 on vehicle, got oil changed on Monday evening and Wednesday morning noticed a burned oil smell and a cloud of smoke off motor after short drive to work. Have oil slick underneath vehicle when came out that afternoon. Went directly back to dealership, and they advised that they had done nothing wrong, but was a bad oil filter adapter. I see a lot of them appear to fail, but the timing is suspect. Has the replacement part been upgraded to prevent future failures?

For months I smelled antifreeze from the front of the Jeep but there were no leaks. After a month I found dried antifreeze on the bottom of the radiator passenger side. The Jeep was under warranty and was repaired by dealer. My friend also with a new 2014 Wrangler also had same problem. Thank you joey

I have a Wrangler sahara unlimited 2014. Around 48,000 miles I smelled burning oil an noticed oil leaking under the carriage when the car was parked. I took it to the dealership and they indicated that the oil cooler was leaking. The engine was filled with oil. They replaced the oil cooler and adapter. This is a potential fire hazard. I hope Jeep replaced the damaged part withone that will prevent the problem from reoccurring.

Burning smell for a couple of days, took it in and they had to replace my oil cooler. Engine was filled with oil and it was a major leak from the back. Part #68105583-ae was put in it's place and I have a sneaking suspicion it was part #68105583-aa that was broken since it was made out of plastic! my Jeep has 32K miles, and is under warranty, but this is too much! recall please!

I recently starting to smell burning oil in my Jeep. I didn't think much of it, and figured there may have been a minor spill or the old oil was burning off after my recent oil change. But after a couple of days, the smell remained and I noticed an oil stain where I park this Jeep in my driveway. I then thought that maybe my mechanic failed to properly install my oil filter after the last oil change. But turns out, the oil filter housing was leaking oil. This is potentially very dangerous and now has to be replaced. And from what I understand, this part is made from plastic and has caused many problems with this specific model year. My sister, who has the same year and model also had to have hers replaced. I only have 50K highway miles on this vehicle. I also noticed that the replacement part has a different part number, so Jeep may have made a modification to the part. I hope so!

2014 Jeep Wrangler rubicon 3.6. oil filter adapter leaking oil. Vehicle has less then 20 thousand miles on it. Took it to the dealer about six months ago and they said they couldn't find anything wrong with it. Took it in two days ago showed the service department pictures of the oil on my garage floor. After reading consumer complaints (2014 Jeep Wrangler 3.6) I told the service department to look at the oil filter adapter. Service department called me the next day and said " you have a oil leak from the oil filter adapter". is this going to be an ongoing problem" will I have to replace this part every 20 thousand miles" I reached out to Chrysler twice about this problem and have gotten know response. I feel there is a potential for and engine fire if Chrysler does not come up with a permanent fix.

Had my oil changed and shortly after smelled burning oil. Didn't think much of it, figured there may have been a minor spill or the old oil was burning off. After a couple of days, the smell remained and I noticed an oil stain where I parked my car. Thought they forgot to put the screw back in but turns out, the oil filter housing was leaking oil. This is potentially very dangerous and now has to be replaced. From what I understand, this part is made from plastic and has caused many problems with this specific model year. A friend of mine also had to replace his. Only have 30K miles on the vehicle so make sure that when you get your oil changed, whoever is servicing the vehicle does not tighten down the filter too much because it can cause the plastic part to crack. Looks like the replacement part has a different number so Jeep may have made a modification to the part.

Did oil and filter change at the dealership. I got on the freeway and looked at my rear window when I saw smoke. Did not think of it much since I figured its the old oil burning. Drove for a good 2-3 miles and it was getting worse. Pulled over to the side and a lot of smoke got inside the vehicle. Got out and the oil was draining over the muffler, transmission cover that was causing the smoke. I thought they forgot to put the screw back on or the oil filter loose. Called the dealership told them what happened and called a tow truck. Once at the dealership, was told by the tech that it might of been the oil cooler that was draining or got cracked, he said that this is pretty common. I checked online for recalls but did not find any but I did notice a lot of Jeep forums online that this was an issue with this model yr. This could be a fire hazard with all that oil draining on the muffler and the engine. Bad design overall! I even know that, it doesn't take a genius to figure that out, its common sense. Making parks with plastic pipes" by the engine and in a hot area" it might be to save money in parts but I am paying on a $40000 Jeep. Got the part 68105583aa replaced with 68105583ae. Hopefully this got motified.

I purchased my Jeep Wrangler sport 2014 with less than 9000 miles on it, drove from fl to co twice. Second time I got to co, car started leaking oil and hasn't stopped since (6+ months). Also, when I accelerate something smells like it's burning. Oil light will not turn off.
