Transfer case rear main seal leak as diagnosed by two different Jeep dealerships (Jeep of hollywood and massey yardley Jeep). I have taken the car in twice for repair and the leak continues (02/24/2017 [hollywood Jeep] and 03/08/2017 [massey yardley]). the car is in for reevaluation and repair as I am writing this making it the third time in three weeks the car is being repaired for the same issue (03/17/2017 [massey yardley]). this involves the motor oil in the vehicle and leaks regardless of whether the vehicle is idle or being driven. Once the Wrangler is driven the the oil heats up, and thins out, causing the oil to leak in larger amounts and faster. This is a safety issue because leaking oil can start an engine fire or too much oil lost can cause an engine to be damaged or even seize. Jeep corporate customer service has been notified of this issue and their "case management" team has been involved in attempting to resolve the issue, however, to-date all customer service reps indicate there is no recall or investigation into these issues. As an aside, the car was taken to the dealer, by the original owner (per carfax report), for transfer case related issues 11/18/2015. I implore NHTSA to investigate this issue as this has the potential to be a life threatening issue.

Engine oil cooler housing cracking and leaking oil. I have had it in twice in 3 months to have the housing replaced. I know of others with this year, 2014, Jeep Wrangler that have had the same problem. You can smell the oil on the exhaust and see the oil dripping under the vehicle. I have the dealer repair orders and parts replaced and they are the same both times. Now, worried it will continue to happen even after my warranty runs out and will have to pay for the repairs. Jeep should extend the warranty as long as I own it or permanently fix the cooler problem on these models.

Noticed pool of oil under my Jeep and upon closer inspection observed oil dripping from back side of engine onto the exhaust system. It appears the leak is coming from the oil filter housing, as seems to be a common failure on this model. Upon contacting the dealer about the part, I was told there is a nation-wide backorder of about 10,000 parts.

Oil cooler leak. Their should be a recall as this can potential cause a fire and everywhere I look people are filing complaints for this exact issue on 2014 Jeep Wrangler...

- Norcross, GA, USA

Purchased Jeep Wrangler as new from dealer with 103 miles on it. At 36072 oil was leaking all over the top of engine and down the transmission. Dealership replaced oil filter housing/oil cooler. After replacement I looked up part number used and it was an earlier revision than what should have used. Jeep was repaired on 2/10/17, on 2/18/17 Jeep was again leaking oil from top of engine.

Oil filler/oil cooler leak

- Roslyn, WA, USA

Oil cooler housing leaking oil into the valley between cylinder banks. Oil then runs over the bell housing onto transmission then onto exhaust crossover pipe. Looks to be an environmental and fire issue. Started leaking at approx. 41000 miles on the Jeep.

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.

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.

- Corrales, NM, USA

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
