While on the highway (according to the Jeep dealership) my oil cooler housing cracked and leaked most, if not all, of the engine's oil into the coolant system. This occurred in 10 minutes and extremely overheated the engine from the time it happened to the time I was able to pull off the highway and safely park. The oil mixing with the coolant caused it to turn into a thick mud-like consistency that clogged up the cooling system and after letting it cool down I opened the radiator then a thick brown oily/coolant mixture seeped out of the radiator. So the radiator was holding pressure prior to bringing it to the dealership. The Jeep dealership replaced the oil cooler housing under warranty along with the radiator hoses but is now saying my radiator has a hole in it and not holding pressure and they are refusing to cover it under warranty, despite the Jeep not having any mechanical issues prior to a hole blowing open in the engine and leaking out oil. The Jeep dealership refuses to test the engine any further even though it ran for 10 minutes with little to no oil in it which most likely caused pre-mature wear. The Jeep dealership wants me to pay $800+ for a new radiator. I bought this Jeep 40 days ago from the dealership and it's still covered under the 100,000 mile powertrain warranty. They are trying to get my Jeep out of their dealership as quickly as they can by spending the least amount of time and money.

Oil cooler housing cracked. This occurred at less than 40,000. I was lucky that I noticed it in my garage rather then while driving the vehicle. The vehicle had to be towed for repairs. If I had been driving it could have caused engine failure. Covered under power train warranty but seems to be a common theme with the 2014S. Come on fca can you seriously cant fix this issue. I mean really.

Oil cooler housing cracking under normal conditions causing oil to leak. Given the relatively slow but consistent leak this problem can go very easily unnoticed but result in catastrophic engine failure and ultimately cause accidents. If this part completely fails there may be no warning time and cause engine seize and/or permanent engine damage. Part has been re-designed multiple times and is a very well known issue in many 2014 and other year Jeep Wrangler vehicles. Part should be recalled and vehicles suspected to have this part inspected for leaking oil. In my scenario I noticed dripping oil from around both sides of the transmission bell housing but unable to trace to the source at first. After reading a few forums I looked down along side the oil filter housing and found a puddle of oil laying in the valley of the engine. Many others have reported this very same issue and the fact that the part has been re-designed so many times and can cause safety concerns, I would like NHTSA so please investigate this.

Oil filter housing leak. $700 repair. This is a piece of plastic that needs to be recalled and replaced for good with something that will actually hold up. This piece failed at 60000 miles...

Summary: Oil cooler housing cracked. This occurred at less than 51,000. We were lucky that it happened in our garage rather then while driving the vehicle. The vehicle was unsafe to drive due to the oil leak and had to be towed for repairs. If we had been driving it could have caused engine failure. Covered under power train warranty but seems to be a common theme with the 2014S. Request research help

Bought my 2014 Jeep Wrangler sport in April 2017, it has a little over 44,000 miles. I noticed a smell of burnt oil, I havent changed the oil recently. After doing some research it appears as the oil filter housing adapter is cracked. Identified as part number 68105583aa. This is a huge issue, and according to the forums I have read a continuing problem. Why is there no recall on this? my understanding is that Chrysler is aware of the problem and has replaced the part with part 68105583ae. Not a happy customer. I hate to spend almost 30,000 dollars and have to repair it after drivinf it 7,000 miles. Complete dissapointment.

Takata recall vehicle was in park noticed oil drops on concrete inspection under the Jeep showed no leaks went to Jeep forum discovered leak was at top, the plastic oil cooler was the problem, oil drips down into a V type reservoir so therefore when you take off at the reservoir full of oil now blows all under the motor. Went on to Jeep forum and noticed that the complaint had been done numerous times by thousands of people where the part before used to be made out of metal was now being made out of plastic so the part is faulty and needs looked into thank you

Oil leak coming from the top of the engine - looks to be under the intake manifold.

- Tillamook, OR, USA

Cracked oil cooler released extreme amounts of oil into engine compartment and throughout engine and undercarriage. The oil spill represents a safety concern for not only road/pavement slip hazard and brake contamination but also presents a fire hazard as it occurs in the engine compartment near electrical and heated elements. After scheduling replacement, part is out of stock due to heavy demand for this particular year. After calling multiple part suppliers and dealers it appears this is a very common occurrence in this year only.

Engine leaks oil from the "oil filter adapter" that is cracked. The oil leaks onto the manifold and gets really hot causing a burning smell. It could potentially set a fire to the engine. I noticed this because of the strong burning smell and the white smoke coming from the engine.
