2014 Jeep Wrangler: engine overheating

Filed May 3, 2024 · Engine · CO

My Jeep only has 60,000 and I already have to replace the oil cooler on it. This causes the radiator fluid to leak and overheated my car. This could cause major damage to my engine and its components. This would also cause the oil to leak into my coolant reservoir. It’s a major defect by Jeep and needs modifications.

Oil filter Housing and Intake Manifold had to be replaced dues a coolant leak. "Common" issue on Jeep's they said. But Despite knowing about this issue, the company has never issued a recall, instead, they redesigned the oil filter housing.

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.

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.

Major oil leak. Took to mechanic. Oil cooler needs replacing. Checked on jeep forum, there are thousands of complaints regarding this issue. Mechanic went to order part 3-4 months for a replacement. Jeep has a back order problem. Was told not to drive as it could overheat and cause a fire. This seems to be a safety issue that jeep is ignoring.

I was just starting a drive home when suddenly my cars "check engine" light came on and it refused to go higher than 3rd gear. Within minutes, my engine was starting to overheat. I was lucky enough to coast into a nearby auto repair place for them to check things out. Their diagnosis was that my oil cooling housing cracked and has been leaking oil everywhere, including the undercarriage (which I'm told is a fire hazard). They also said it's a very common problem with the 2014 models and they're shocked jeep hasn't issued a recall on it. I later did some reading and found hundreds, if not thousands, of other people who have had the same problem. A recall should be issued for this faulty part instead of making all of us pay $750+ to fix it.

Oil cooler had a major leak oil on top of engine was easily a quart. Rest of the oil had traveled down the transmission and covered almost the entirety of the engine compartment and exhaust. I noticed the leak by a strong smokey oil odor as the oil hit the exhaust. The oil cooler was replaced and must have also caused a leak in the coolant because the reservoir was near empty. Waiting to see if that was the cause of the coolant leak.

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.

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.

Coolant leak from radiator, passenger side top corner under shroud. I have two 2014 jeeps with the same leak. Seems to be a manufacturing defect as there are many threads on the internet with the same issue. My warranty is expired but these are only 2 years old and should not be failing like this.
