While driving I observed smoke was coming out from my vehicle engine compartment with the odor of burning oil. I was just around the corner from my house so as I pulled into my driveway I looked under my vehicle and noticed oil dripping from under the engine on to the exhaust pipe. I am aware that 2014 Jeep Wrangler have a problem with the oil filter housing cracking over time. I opened my hood and looked at the oil filter housing and there was oil all over the top of the motor. I went to my local Jeep dealer and was told that this year Wrangler has a big problem with this and that there is no recall. I don't understand how a safety issue like this that mopar has not been called on the carpet for a fire hazard like this and that they are aware of the premature failure of this part. I was told the repair would be roughly $600. Could you help me resolve this issue and what appropriate action I can take. My vehicle only has 35,000 miles on it. Not to mention my driveway is a mess :(

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.

I recently had a change oil indicator go off, earlier than anticipated. While performing the oil change, I realized there was oil all over the bottom of the vehicle, especially on the bottom of the transmission. I cleaned up and performed the oil change. Two days later the same thing. Fresh oil everywhere. Upon further research and a trip to the dealer, the conclusion was a bad oil filter adapter assembly. This is beyond common on a 2014 Wrangler. Insane that there has not been a recall on this part. Come on Jeep, get it together and take responsibility. I love my Jeep. But right is right. This is beyond a big fire concern!!!!

Ticking noise from the engine on both driver and passenger sides. The noise becomes louder when the engine gets warm, especially when it is close to a wall or other vehicles. Diagnostic from dealership says it is due to rocker arm failures.

Oil filter housing is leaking, causing copious amounts of engine oil to leak over the engine and transmission and dropping down on to engine exhaust causing it smoke and emit noxious fumes into the vehicle cabin. Potential for fire is extremely high, I had to pull over and exit vehicle due to the amount of smoke coming into the cabin from the underneath. Upon investigating I initially thought my transmission had blown a line because of how much oil was coating the undercarriage of the Jeep.

The engine oil cooler assembly is leaking a large amount of oil into the "V" of the engine and dripping on to the exhaust manifolds. The vehicle was parked for over a week and upon driving smoke with the smell of burning oil filled the passenger compartment. To the extent that the vehicle needed to be pulled over and inspected for fire and damage. It was noted that the transmission, frame rails, and exhaust pipes were covered in oil and the vehicle was approximately 2.5 quarts low on oil. No prior signs of an oil leak were present before the smoke and burn oil smell was noticed during normal use of the vehicle.

While driving noticed an oil burning smell, got home and looked under the hood and found a pool of engine oil. Found out from owner of the same car that a broken oil cooler assembly. This could have cause the car to burn- very dangerous indeed. Happens in lots of Chrysler's vehicles

Another 2014 Jeep Wrangler owner with a cracked oil filter housing/cooling assembly. Oil is spilling out all over exhaust. Certainly a fire hazard. With as many complaints with this particular part that I have seen all over Jeep forming and on the NHTSA site I am surprised that Chrysler has not taken any action but is leaving this to their owners to rectify.

Massive oil leak at the oil cooler housing. (2 quarts per day). Leaking on the top of the motor and leaking down the back passenger side engine directly over the hot exhaust manifold. Leak occurs at all RPM ranges and leaves massive puddles of oil everywhere I go which is not good for the environment. And presents a fire hazard if stuck in traffic and engine temps rise enough to cause ignition of leaking oil over a hot exhaust manifold.
