Wrangler Saraha

  • Automatic transmission

With less than 60k on 8 year old vehicle - and it's over 1100 to repair a known issue of a bad design. This is not for lack of care, but poor design by Jeep. Should be covered by them even at this milage.

I'm another owner of the 2014 Wrangler 3.6 that had the cheap plastic oil filter adapter crack and dump all my oil on freeway, that resulted in a blown engine with only 18,000 mi. I'm waiting for new engine, but very upset I never knew about problems (with that part) until engine failure.

Sucks Big Time!!!

Jeep knows about it, its not considered safety - what TURDS they are... Dealerships say it's not a warranty item... Really?

Not even offering Parts or Labor free. At least parts should be.

1- $1000 to fix it...No choices, taking it to the other guy scare me. 2- Home Owners Fine - $150 for clean up. 3- $90 City fine for environmental. 4- Loss of Jeep for a day ( 4 min Labor). 5- No Guarantee it won't leak again.

oil housing leak oil housing leak


I'm so frustrated with jeep "stealership".

Everyone at Bolles Jeep in Stafford Springs acted like I was the only one in the world with this problem. Thanks to you folks and Jeep forums I have proven that I haven't lost my mind! (Don't ask my wife however, she will disagree!!)

I went to the stealership to get a quote and speak to the lead tech about my issue. He claims to not have had the problem there before, nor to acknowledge it is an actual problem. I find it crazy that so many people have this issue. I also became aware I was being lied to because they carried the part in stock, if I had chosen to let them rip me off with this repair that is clearly a known Jeep issue. I say it is known because it is only the 2014 model affected and the design of the oil cooler was promptly changed for the 2015 version... hmmmm?

So the worse part is they wanted $900 to repair this issue (at the top of the motor, mind us all)... they wanted $400 for the part that I found on amazon for 85.50!!!!


I'm very frustrated. Please log your complaints here, boys, so we can get some stealership justice!!

My oil housing is cracked and leaking all over the engine. My car is out of warranty by 6 months and the dealership will not fix. This seems to be a very common leak on the 3.6 l 2014 Jeep Wrangler.

Wrangler JK 3.6L V6

  • Automatic transmission
  • 48,500 miles


Experienced a very noticeable oil leak in the driveway, which was a result of a bad oil filter housing and cooling assembly. Cost to repair and replace was $300 for the part (from the dealership) and 3.37 hours of labor. It cost me close to $700 and I'm worried that this is going to happen again in another five years. Based on the frequency of this issue, I'm very surprised this hasn't been a recall item.

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.

oil housing leak oil housing leak

Like so many other owners with this model year, my 2014 Wrangler JK has an oil housing (part # 68105583A$) which is leaking.

The initial symptom is an odor which occurs when oil leaks onto the hot exhaust cross over and burns. If you climb under you Jeep you'll see something like the first photo where drops of brown oil are pooling and dripping (in this case off the transmission). You may also see blacked, scorched oil blobs.

If you follow the oil "forward and up" you'll find it pooling in the engine block's valley, as shown in the second photo (background, center) under the Oil filter adapter/housing (foreground).

No warning light, alert, or other indicator has told me about this problem. If I hadn't been curious, I wouldn't have found it until it was much worse.

FCA is aware of this problem as seen in Service Bulletin Number 09-008-15. As of 2016, they are investigating the problem and have requested dealers use dye to verify the source of the leak before replacing (see Manufacturer Communication Number: 68105583A).

The fix, as outlined in several excellent Youtube videos, is to replace the defective part. A replacement part can be had for $120 - $400. However, it is a time consuming process requiring removing the intake of the engine and will cost several hours of labor to correct.

It is important you, or ideally FCA, correct this problem for two reasons:

1) Leaking oil is toxic and a serious fire hazard if it contacts a hot surface. 2) If your engine oil level falls too low, your engine may stall. You may not receive any advanced warning of this. This sudden engine failure is a serious safety risk.

Engine oil filter housing broke. Part is back ordered, waited a month so far to get it with no part yet. Seems like every 2014+ Wrangler has this issue so I'm unsure why Jeep hasn't tried to fix it or at least make parts available for the issue.

Wrangler Sahara 3.2L V6

This problem seems to be a problem a lot of Jeep owners have incurred and have spent a lot of money to get repaired. It seems the jeep manufacturing company has not addressed this problem and made it a recall and redesigned a part to fix it. The oil cooling case made from a plastic material is cracking over time and spilling engine oil over areas that could and probably will cause a dangerous fire and possible injuries.

(reported on)


  • Automatic transmission
  • 29,000 miles

We have a 2014 Wrangler with 29,000 miles on it. Like many others we are experiencing the oil filter/cooler housing crack and leaking all over the engine down and onto the transmission housing. It’s a very dangerous situation and a huge fire hazard. I’m amazed that this hasn’t warranted a recall as it’s a huge safety issue. Not to mention as you do a lot of research it seems thousands of people are experiencing the same things and seems to be a design flaw that should be fixed and not at the vehicle owners expense. It seems the safety board of some short should step in and make the manufacturers fix this problem before someone gets hurt.

Wrangler Wrangler Sport 3.6L V6

  • Automatic transmission
  • 38,071 miles

The oil leak began in September 2019 and after 3 months of trying to find the leak, it was finally located after the transmission was pulled when doing transmission work where it was found to be the O ring on the oil filter housing. The 2014 Jeeps do have a known problem to have the oil filter housings to crack and go bad (and I did purchase the entire unit for replacement just in case); however, in this instance, it was a mere $2.50 O ring which was causing a severe oil leak....upwards of 2.5 quarts of oil every 2 weeks being depleted. That little O ring is very important.

Update from Jan 19, 2020: Jeep refused to pay for this repair stating that my Jeep was no longer under warranty. In addition, I did not take my Jeep to the dealership for this work either as they are hugely expensive and I do not trust them doing work on my Jeep. Therefore, this was done by a third party repair shop.

Wrangler Sport 3.6L

  • Automatic transmission

big oil leak under my jeep. as I was driving home almost at my house I noticed smoke and the smell of burning oil from my vehicle. pulled up my driveway and looked under my Jeep and noticed oil dripping from under my engine and down onto the exhaust pipe. I then checked my engine compartment and there was oil all over the top of the motor around the base of the oil filter housing. I went to my local jeep dealer and was told that this housing cracks and is a common problem with 2014 wranglers and the 3.6 engine. how in the world is this not a safety recall. besides being a fire hazard what if I was traveling on a highway with all this oil pissing out all over the road and the exhaust pipe. I also checked on the jeep wrangler forums and this seems to be a wide spread problem. I own a 2019 F250 that has a recall because the headrest fails to conform to the Federal Motor Vehicle Safety Standard. but something as serious as this , a fire hazard is no big deal. My jeep has 35,000 miles on it. Itys time Mopar did the right thing and stand behind their product. its no wonder when you read consumers magazine they beat the crap out of the Jeep. take some pride in your product Mopar and stand behind your product. how can you say the jeep is trail worthy when it cant even handle the daily driving on the roads.

Wrangler Sahara Unlimited 3.6L V6

  • Automatic transmission
  • 72,000 miles

Why Jeep Fiat decided to make an inferior part prone to failure is the question. Give me the old spin on oil filter I used to change myself when I was younger. Watched video of how this is replaced and it is a major job requiring taking apart several engine parts to get to the housing which the dealer charged me 315 just for the part. Jeep, Dodge, Chrysler and Ram have this engine in a lot of their models. This should have been a recall or extended warranty with so many failures. Stay away from this engine. I will add another complaint to follow because the engine was ticking before this repair and in addition to the 800 to repair the ticking required replacing lifters and rocker arms inside the engine. Along with brakes and power steering leak the total bill was $2900! Yikes!

Oil filter housing adapter cracked and started leaking oil. Dealer said repair would have been covered by 5 year/100k drive train warranty but I passed the 5 year mark 4 months ago, so it was not covered. Frustrating that this is a known issue and there was no recall. Not impressed with Jeep.
