I started noticing a burning oil smell occasionally and would check to see if I could see any oil leaking - no luck. After about a week of hints of the smell, I started to see oil spotting under the vehicle on the passenger side on cross members on the bell housing and other locations under the hood. After some research, I checked the oil filter housing/cooler for oil puddling on the block and sure enough - there it is.

I find out that this model year Jeep went from a metal housing/cooler to plastic. Plastic for a part that handles extreme temperature changes and one of the vital parts of the engine protection system. So I go to dealership to check and they state your powertrain warranty expired in June. 5 years have expired and it only has 71k on it. No recourse but to fix out of my own pocket. Really Jeep. Plus no recall for the part that is failing for thousands of Jeep owners.

Now I enjoy my Jeep, I'm a Jeep fan, but to do things like this to save cost - not good. Cheap parts that they know will fail and not giving any recourse - bad move, Jeep.

So dealership states while I'm there - we can't get to your car until the middle of February - what? How in the world do people run business like this? So basically 2 months without my car - nope. I'm going to go to a local mechanic to have it fixed and hopefully find a better aftermarket product to replace the cooler with.

My 2014 Jeep Wrangler suddenly started leaking all over my driveway! I brought it to a mechanic who thought they fixed it but turns out, the real problem is the oil cooler assembly, which I was told need to be replaced "immediately". I had my level checked and the stick was bone dry and I went to a mechanic and I had leaked out more than half the oil. The manager there said they are seeing this with a ton of Jeeps and he told me it was a recall, but that seems to be incorrect. He said Jeep is not wanting to pay for this because it is happening to so many people and Jeep of course said it is not a recall. Very frustrating!

  • Automatic transmission
  • 70,000 miles

Bought my first Jeep used with 64,000 miles in excellent condition with no leaks. Brought to local Jeep dealership for an oil change (online coupon for 2 changes and tire rotations for 79.99). After a second oil change, it starting leaking oil, covering bottom of the Jeep in oil.

I'm buying parts for repair on Rock Auto for 200.00 and doing repairs myself. I thought a Jeep dealership tech would be more aware of the subpar design of the filter housing and take necessary steps to avoid this problem. He probably thought job security. But I think not! I just hope this won't be a consistent issue. Very disappointed in my first Jeep product that is already over priced in my opinion. But they are an absolute blast to drive!

Obviously there is an issue when you put plastic oil filter housing and oil cooler on top of a hot engine. There are seals that harden and start leaking. The engine has valleys and pool areas for oil to collect till those pool areas overfill and run down the engine and transmission housing working their way to the exhaust pipe where they cause burnt oil smell and smoke if left unrepaired. It's about $1000 every 5 years (at the dealer) unless you do it yourself.

The part has been upgraded from Mopar Part No.: 68105583AA to 68105583AF. When you replace the oil filter housing and cooler, make sure you lube the seals properly. UTube has good videos for details. Takes 3 to 5 hours depending on how many you have done and your skill level.

Wrangler Rubicon V6

  • Automatic transmission
  • 80,000 miles

2014 Jeep Rubicon. Oil leaked all over the garage floor after a hour long trip. Obviously mostly leaked out during drive as it was almost completely empty. After evaluation it was a faulty oil cooler. Replaced in October 2019, but saw a leak today as I watch this closely after that ridiculousness. I opened Jeep's hood, took off cover and shined a light down beneath the filter tube - and low and behold a pool of oil down in there where there was not last week. Lovely, seems to be progressing.

I have read that others have had to replace theirs more than once. I am assuming its due to the shoddy parts being added to a vital part of the engine that needs to be protected better by completely different heat manageable materials. My Jeep not in warranty any longer and this is like heart surgery. Yay Mopar. Recall this OIL COOLER and put in a part that is as tough as the rest of the Jeep?

Wrangler Rubicon 3.6L

  • Automatic transmission
  • 116,932 miles

This problem appears to be common from 30,000 miles up, could happen at any time! The numbers on the oil adapter (yes the part numbers) indicates that particular part has been changed. Notice that the last letter in that oil adapter number is { 68105583AF} F means that part has been redesigned 6 TIMES. The intake gasket number is ms19879. Maybe we will find in the future, at our own expense (!!) or at Mopar EXPENSE that plastic will not work in changing temperatures under oil pressure. How many motors are at the junkyard as a result of not catching this soon enough?

We started the car with the remote (it was winter back then) and all of a sudden heard a loud "POP". I looked around and everything seemed okay. My wife went off to town.

A while later, I followed a trail of oil where she backed up. I called her and sure enough there was a giant puddle of oil under the car. I had it towed to a transmission place (past warranty, there's no point in paying giant Chrysler dealer costs!) because the oil was all over the transmission.

It turned out it was the oil filter housing that was cracked. I have owned cars for 45 years and NEVER had something like this happen! Now today my son's 2012 Jeep seems to have the same problem. Stay tuned.

It's got only 64000+ miles and this piece of crap part started leaking oil all over the exhaust out of nowhere. Jeep is supposed to be an icon. I'm going to sell it and buy a Toyota... do not buy a Jeep product with this part, you will be sorry, and lucky if your Jeep doesn't catch on fire.

Wrangler Sahara 3.0L V6

  • Automatic transmission
  • 68,351 miles

My Jeep is a 2014 Model and I purchased it in 2015. This car is my only American made, my other 2 cars are Japan's. The car cost about 44K in my country and it's considered as expensive. Owning it after 6 years and having this problem really pissed me off. I had my 2006 350z for 15yrs without any problem except wear and tear parts, and the only problem I had was a worn out spiral cord that triggered the ABS light last year, and that's after 15 yrs. I'm expecting that at the price range it should at least start to have problems after 10 years.

I replaced the ABS module 8 months earlier, when the ABS comes up again and it happened to be the ABS sensor was going bad. Again within a year, two problems comes up and it really annoys me. On top of that, I have to wait for 6 months for the parts to arrive from the dealer. After a week replacing the bad sensor, the ABS lights came back again and it happened to be the same sensor. I didn't expect the parts from the dealer, which is genuine Mopar parts, could go bad in a very short while. Imagine the frustration.

This time I order the parts from aliexpress and installed it at another workshop and it is working properly for now. After less than a month, I started to smell some burning oil every time after driving the Jeep, than checked under the car and saw some drips of red liquid on the floor. So I brought it to the workshop and they said the flywheel seal was worn out and needed to be replaced, luckily the parts are in stock at the dealer. a day after getting it back from the workshop, I can still smell the burning oil, again I checked again underneath the car and saw some yellowish oil on the floor. I really don't know what to say, I started to question myself why I bought this car in the first place.

Again, back to the same workshop to check it out and find the source of the leak, it's from the oil filter housing. We check with the dealer for the cost. The housing itself cost about $440! So we went for a cheaper option and replaced some of the worn seals. After a day, I got the car back. the smell is still there. Feeling helpless, I went to the workshop again for a check up. The seal replacement did not fix the problem, so we ended up purchasing the housing and replaced it. After a day I got the car back and hoped for the best. I still can smell it but not as much as before.

After 3 days using the car, the smell of oil burning is still there, and there are no trace oil spill on the floor. I courage myself to go and check under the car and found some oil traces on some parts of the engine!!! I decided to surrender myself to the dealer for them to check the Jeep thoroughly and fix any problem once and for all!!!! I left the car at the dealer and received a call from them a week after and told me that both Head cover gasket need to be replaced. So I said go ahead and fix it. It's been a week now since I got my car back. So far so good.

Oil filter adapter has a crack and is leaking oil. Found out the warranty expired 8 months ago and Jeep will not cover the replacement. I call Jeep customer service with no help. After watching video on how to replace myself, it looks like a big pain in the ass and had to take it to a shop and get it replaced for $700 dollars. This seems to be a known problem and all over the internet and Jeep would not help out on the warranty.

After identifying leak had dealership troubleshoot for source. They stated the leak was at the oilcooler/filter housing. Got online and it apparently is a common problem that occurs around 30,000 miles. This is a very expensive problem and in my humble opinion should be a recall or at least covered by the manufacturer.

Wrangler Sahara Unlimited 3.6L

  • Automatic transmission

My wife and I took our 2014 Jeep Wrangler to the dealer 01-13-18 for its scheduled oil change@ Kings Dodge Chrysler Jeep & Ram in 4486 Kings Water Dr, Cincinnati, OH 45249 (513) 683-3000 . We bought the Jeep from them and have a lifetime oil change..

After taking it home a month or so later we noticed a smell of oil burning. Getting close to the next scheduled oil change I noticed a small spot of oil on the driveway where it is parked. We took it in for the scheduled oil change 11-10-18 and told them that it was leaking oil. After they changed the oil and brought it out to us. I was told that the leak was caused by the filter not being tight enough.

We took it home and with in a month or so notice oil on the driveway. Finding time to drive 40 miles away to Kings Dodge Chrysler & Jeep Ram I took it in. I was told it was no longer covered since we had a few hundred miles over the warranted miles covered. They were willing to take it in to see what the problem was, but it would no longer be covered under the warranty.

After a lengthy conversation about my last Oil change (there) I had pointed out it was leaking. I told here you guys said it was because the oil filter was loose which at that time we were within the warranty. She still insisted that we would have to pay and at this point I felt she had dismissed me and was not going to work with me at all.

I decided to leave and call directly to Chrysler and ask what my options are. I called and talk to Chrysler which was very helpful. The lady on the phone expressed her concern and gave me a few dealers to take it to. She recommend I figure out what is leaking and call them back to see what they might be able to do for us.

I picked Key Chrysler Jeep Dodge Ram - Tobey Auto Group 2020 N Detroit St, Xenia, OH 45385 (937) 372-4451 and dropped it off on 2/4/19. They called me Monday and said the Oil Cooler was cracked and leaking. I called Chrysler back and they started a claim for us. As of now it is being reviewed by Chrysler.

Wrangler Unlimited Rubicon 3.6L

  • Automatic transmission
  • 55,000 miles

Noticed leaking fluid after I had an oil change completed on the Jeep. Different shop that was doing upgrades to my lighting/steering components noticed and brought it to my attention - I hadn't noticed the leak on my black driveway. Brought it to dealership - they found the leak was coming from the oil cooler as it had cracked just like the forums and everyone else has mentioned. They replaced it under the warranty and it took only a day to fix (after a 2 week wait for an appointment).

Overall just an annoyance and disappointment that this known issue hasn't been addressed, but dealer was very easy to work with on the fix.
