Engine oil cooler failed. No warning lights or chimes. Problem found by smell of burning oil covering the intake valley and drainage from there onto the exhaust pipe throughout the underside of the vehicle. Can result in a vehicle fire.This is a known problem with the 3.6l jeep engine. This is a costly repair and replacement part of OEM quality or better is difficult to locate because of so many failures.

- Wills Point, TX, USA

Oil Filter Housing failed leaking oil onto top of motor and hot exhaust manifold nearly causing a fire and catastrophic engine failure in heavy traffic. Dealer has confirmed this is a known issue on the 3.6 pentastar engines from after 2014. Currently replacement part has a 58000 unit back order. Failed with no warning until oil light and temp lights triggered.

After a short drive to town I could smell oil burning.. Oil was Pouring on the the ground from under my jeep. I was told from the dealer it is a common problem on that motor and it was the OIL COOLER. It was cracked on the plastic part. I had it repaired and it cost me 800$. There were no warning lamps. If I did not catch the problem in time the motor would have locked up.. the oil hitting the hot manifold could have caught fire.

3.6l Pentastar V6, vehicle had a failed oil cooler housing. This caused the vehicle to leak a considerable amount (more than a quart) of oil into the valley between the cylinder heads, but showed no outward signs of leaking oil. This has the potential to ignite a vehicle fire during operation. Could also potentially cause catastrophic engine failure secondary to oil starvation at highway speeds.

Engine light on when change in oil needed @ 50%. Oil pressure fluctuates when driving 2% to 30%. Noticed oil leaks in my driveway and had it checked by mechanic. Found out it was the oil filter housing/oil cooler and that it is a common problem with 3. 6 motor also, found out the part is on back order due to a lot of customers having same issue. Found the following in my search: " ATTENTION - 2014 Wranglers have bad oil leak problems! ________________________________________ For 2014, Chrysler made a change to a part called the "oil filter adapter" which sits on top of the engine, under the intake manifold. There are now a parade of people with various Chrysler vehicles that use the 3.6L reporting that the new part cracks, causing a major oil leak, potentially a fire, and can cause your engine to be drained of all oil. If you have had an oil leak, and the dealership told you the issue was the oil filter adapter, the oil cooler or the oil cooler cover, post up here. We are going to try to get pressure on Chrysler to at least redesign the part. Part number is 68105583AA and it applies only to 2014 3.6L Chrysler V6 engines, at least so far. Similar issues have been reported with the new 3.2L V6 used in the Cherokee, but it apparently has a different part number. This is a MAJOR issue if you own a 2014 Wrangler. There is no way to know if/when the part will crack, and if it does, it is not a trail repair. The adapter is buried under the intake manifold, and ever getting to it with some putty would be nearly impossible. You had better have extra oil with you at all times if you are trail riding a 2014 Wrangler. Post here if you have the issue, and go to safercar.gov and file a complaint. If Chrysler doesn't fix this issue, you will never feel safe wheeling your 2014 Jeep in the backcountry. They need to fix this, NOW. ALL 3.6L vehicles are affected"

Concerning all Jeep Wrangler vehicles with the Pentastar 3.6L V-6 engine. These engines utilize variable valve timing with DOHC-??s. Jeep dealers and owners are aware of a very common issue with bearing failures in these assemblies, resulting in damage to the camshafts requiring replacement of all 4 camshafts, 24 hydraulic lifters and 24 rocker assemblies. Approximate labor for this work is $1,220 plus parts cost of approximately $2,770. The issue is signaled by a loud tapping noise from one or both engine banks and typically occurs around or shortly after 80,000 miles though there are a number of reports that can be found where this issue appeared earlier. Jeep technicians diagnose the issue using a stethoscope and automatically assume all components will require replacement without further disassembly or investigation. An internet search will indicate just how prevalent this issue is. My vehicle is currently in the shop and I am told there are currently a total of three Jeep Wrangler Unlimited vehicles in said shop with the SAME issue.

Smelled burning oil coming from the engine bay. Noticed a large amount of oil under the engine. Inspected the engine bay and there was a pool of oil under the oil filter housing. There was no CEL or warning. Checked oil and it was over a quart low. Oil spill under vehicle was large and dissipated in a wide area. A quick web search shows this is a common issue on the Chrysler Pentastar 3.6 engine. It is the OIL COOLANT HOUSING ASSEMBLY which is faulty. This causes oil to spill out and drip on the transmission and exhaust which causes the oil burning smell. There was a backorder on this part and I was informed that over 65K parts were manufactured and sold this past year which demonstrates that this is a known issue. Attempted to have dealership repair but could not book a date for months due to backlog and lack of availability. Took the vehicle to an independent shop that was very familiar with the issue and confirmed it was the oil coolant housing assembly without me mentioning what I thought it was. This was a $975 repair. Contacted manufacturer and they said they could not assist me as I need to take the vehicle to the dealership (only). However, I can't be without my vehicle for 60 days until they are able to "fit me in". Concerned about the burning of oil on the exhaust from a safety/fire perspective.

Oil Filter assembly (FCA Pentastar 3.6L) started leaking oil and poured out over the back of the engine and got on the rear tires causing a loss of control of the vehicle. No warnings were indicated and the event occurred where my wife and others could have been hurt or killed.

This is another complaint about the oil filter and oil cooler assembly problem that's known on the 2014 Wranglers. It's made of plastic (that cracks) with plastic gaskets (that shrink/crack over time). It's a known problem, has been reported by many, especially for vehicles in cold weather areas. Due to the location of the oil cooler assembly, it can't be easily replaced without spending over a thousand dollars and then the dealers don't stand behind or warranty the new part/their install because they know the replacement is just plastic and going to crack again. Oil leaks all over other engine components (transmission, transfer case, etc.), which could cause the vehicle to catch on fire; an accident due to the leaked on components being deteriorated and not working properly from being oil soaked; or cause the engine oil to overheat since the cooling assembly isn't working correctly. Repair requires complete disassembly of the upper engine and the OEM replacement is just another faulty plastic parts. Repairs are extremely costly IF you can even find parts. OEM had to know about this issue---plastic parts are never good and hopefully no one will get hurt because you could be driving a long time before you even know you have a problem.

- Street, MD, USA

The oil filter and oil cooler assembly is plastic with plastic gaskets. It will often crack, or the gaskets will shrink/crack over time, particularly in cold weather conditions. This causes oil to leak down onto other components, specifically the transmission, transfer case, etc. in the case of an accident this oil leak and oil soaked components can represent a fire hazard. Also can become an engine oil overheating issue as the oil cooling is not working properly. Repair requires complete disassembly of the air intake system and manufacturer only supplies the same faulty plastic parts. Repair is extremely costly and it is a known defect that has caused many parts shortages.

Issue with lifters ticking at 49k miles

- Fruita, CO, USA

I was driving the vehicle at 30 miles per hour and the engine accelerated to 60 miles per hour on it's own. before I could get it to stop. This occurred on 4 different occasions of the vehicle accelerating on it's own. The vehicle was only able to get under control by stepping on the brake hard placed the vehicle in neutral and shut off the Key. Some one could of been killed. No Dick Chrysler dodge stated they would have to drive it to see if there was an issue and charge an outrageous amount of money to determine if there was an issue. I know there is an issue. No one has inspected it as there was no accident There were no warning signs that came on. The first occurrence of the issue was on 8-

64000 miles oil filler housing cracked out of nowhere and started leaking oil all over the exhaust. smoke was coming off the exhaust into the jeep I was afraid the jeep would catch fire so i had to tow it home. this part made out of plastic is breaking on many jeeps because it is defective in design. it cannot do its job.oil leaking all over the road and onto hot exhaust is a dangerous result of this poorly designed part

- Las Vegas, NV, USA

Dealer reported crack in oil cooling housing. A burning oil and coolant smell starting in 2017, while under manufacturer warranty. I was concern that jeep would start a fire and began parking outside. I replace the oil cooler because I noticed a ticking sound. When I went to the dealer they informed the the engine is a total loss and needs to be replaced. Cylinders 1 and 6 failed. $8000 to replace the engine with a refurbished unit which addresses each of Chrysler-??s failed 3.6 liter motor. If this manufactures oil cooler and other engine issues, do not need to be addressed, I don-??t know what ever would need to be addressed.

My Jeep Wrangler was having significant engine issues with shaking, random noises and vibrations, and it turns out the Engine Oil Cooler had a crack in it and leaked oil all over the intake manifold/under carriage of the vehicle. Upon speaking with over 15 dealerships in Southern California, they noted that there were over 40,000 of this replacement part on back-order as of March 2020. I had to wait two months to get the part delivered, which meant I went two months without a vehicle, and then had to pay over $800+ on a part + labor on an item that should absolutely be recalled. There are thousands of posts on Wrangler Forum and other Jeep pages that share the exact same issue. Jeep has ignored this issue since 2014, and it's only occurring in more vehicles now. This part breaking can cause engine seizure or failure and should not be a cost to the customer as there is CLEARLY a nation-wide problem that Chrysler is ignoring.

- Santa Monica, CA, USA

Need to replace oil sensors, filter housing & intake manifold gasket set-warped. Oil leaking everywhere due to cracked housing. There have been complaints since 2014 in all makes of Jeep/Chrysler cars and they refuse to recall/fix. This is a serious danger!

- Northbrook, IL, USA

It started with a small oil leak that turned into a big oil leak coming from the oil cooler. The high the temperature the more oil that would come out. This oil is mixed with coolant as well. This is not safe because you never know when it's going to crack and they will not cover under warranty or extended warranty. This can be a real safety issue because you can lose oil pressure which can cause engine to fail.
