Eight problems related to coolant leaking have been reported for the 2014 Jeep Wrangler. The most recently reported issues are listed below.
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.
Leaking oil filter housing. It's a known problem and so widespread across Jeeps that there's a national shortage of the part. I can't even get it fixed. Oil and coolant are leaking everywhere. It's a danger to my family and the environment.
2014 Jeep Wrangler oil leak noticed oil on carport checked low on oil its an oil coolant housing crack have called for a month and a half cannot get part its on back order which is now up to 60,000 was told tighten bolt and keep checking oil I may be a female but it's not gonna keep being just a crack will end up tearing my Jeep up or cause accident its my only transportation was told by guy at dealership its made to go out when warranty expires it needs to be a recall on the part since it can cause more damage ## #vpic# 1 - check digit (9th position) does not calculate properly #vpic#.
The oil cooler/oil filter adaptor failed. This part is plastic and sits on top of the engine. . . . ! since 2014 this part has failed in many fca vehicles and when it does it leaks oil and coolant on top of a running/hot engine! in my case it failed and caused a loss of oil pressure which then damaged the cam shafts and O2 sensor. Luckily it was covered by warranty but when that runs out it's not only a safety issue but a very expensive repair for a failing plastic part that should have been recalled by now! the company should at a minimum extend the warranty for that part on every engine it has been used in.
Oil adapter housing cracked for the second time in 6 months. 1st time caused external leak and it was replaced. This time cracked again but internally causing oil to leak into coolant. Caused $3200 worth of damage and had to have coolant system replaced as well as heater coil and hoses. I know of 7 other Jeep Wranglers this has happened to recently.
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.
Engine coolant and oil sprayed the underside of the Jeep started smoking paid to have it fixed then 4 months later the coolant is starting to leak again. Was told the parts are cheaply made and I am better off ditching this Jeep before it catches fire.
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.
