Hey! So I just purchased this 2015 2 door JK a few weeks ago. I was underneath the Jeep for an unrelated reason and happened to see this dark wet area. I’m not mechanically inclined whatsoever, so is anyone who is able to spot where this leak may be stemming from? Oil level is fine. Never any spots or anything on the ground so I’m assuming it’s very slow. But it does definitely appear to be brown engine oil. Any insight would be helpful! Thank you

2014 and some 2015 suffer from problems with the plastic oil filter housing. That's the first place I would look. My 2014 had the problem.

If not the oil filter housing, next bet would be oil cooler which is another common failure in those model years.

On the 3.6L, the filter housing and oil cooler are part of the same assembly. As noted, this is most likely your issue and was very common on the '14/'15. The Mopar part costs ~$180-190, and it's usually a 3-4 hour job to do at home. I have no clue what the service book says for repair time, but since it sounds like you would be going to the dealer you could be looking at a $500-$600+ repair (just ballparking). The real unfortunate thing is that unit sits on top of the engine under the intake manifold. There is no way to get a good visual on it to verify without tearing things apart. None of us can say without a doubt that is the issue you're having, but that is the most likely culprit.

For what it's worth, the part we're talking about looks like this -

You'll recognize the top of the oil filter housing that you see in the top of your engine bay.

There are plenty of videos out there too which can give you an idea. this is just one of the first ones pulled up in search (not necessarily the best one) -

My Wife's 2012 had the oil cooler leak. The Jeep lost a 1/2 quart of oil in 20 miles, what a mess. Once repaired it was fine. I think it was a $500.00 or repair like Re Sharpe stated.

yes, you were spot on. Took it to the shop today and they confirmed it was this housing leaking. Pretty spot on on price too, about $500 all together. Thanks for the input!

Well, sux that it is/was an expensive repair, but at least a common, well-known issue and not something you'll be chasing for a while. This seems to be a much bigger issue on the '14/'15 than other years from what I see. IDK if maybe they just had a bad batch or what.

Thank you for updating on the issue/repair. Price appears reasonable; especially for the Lakewood area.

definitely! Globex performance in Toms River. Having a regear done by them in a couple weeks as well. Best in the area

Hey, I'm right next door in Brick. I used affordable automotive on Brick blvd. The Jeep was there for a broken valve spring and they noticed the oil leak from the housing. I'll have to check my receipt, but I think they charged me $800 for that portion of the repair. Nope, correction. The part was $353.70. Can't tell what the labor was because the engine had to come apart anyway to fix the broken spring and replace the cams. I was happy with their service. I normally do my own maintenance but the spring and cam repair was beyond me.
