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.

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.

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.
