Leaking oil due to oil cooler failure. This is a known issue on the 3.6L penstar engines and Chrysler Dodge Jeep does nothing to repair it. I have looked up plenty of threads and videos on this and this is not a easy or cheap repair. The result is oil leaking from the back of the of the intake manifold and down the back of the engine and to the ground.

While driving moderate speed on a rural rd (est miles 115K), all red & yellow lights came on, "no bus" light came on which is not listed in the ops manual, windshield wipers came on, RPM gauge went to zero, fuel gauge went to empty, engine light flashing and engine running rough to possible stall. Within a period of time 10 min or so everything came back to normal and Jeep ran ok. This has happen to my wife who is a rural mail carrier on many occasions. In fact in 1 week it happened every day and it has happened many times over a long period. Jeep service folks don't know what is causing the problem as the codes do not pin point the problem. They "think" possibility it could be pwr fuse box, main computer or fwd instrument panel ea at a cost of over $1000 to replace. Service folks want T Jeep brought to them with lights on, gauges zero, engine light flashing but it's an intermittent problem and they are 30 miles or more away depending where the problem happens. Service folks have had the Jeep for a total of 3 days in Jan & Feb and drove it over 150 mile and the problem never appeared. In Feb 2015 while driving (24,171 miles) the engine light came "on" and Jeep stalled in the middle of the road. It was restarted and driven so Jeep was then taken to dealer and they found that a fault code said "wiring does not have enough slack between sensor & wiring causing poor connection". replaced cam sensor & wiring. Fault cleared. Have photos of dash with "all lights and gauges showing zero and no bus light on and wipers going back and forth. I'll send if you need them but it all lights and gauges which are depicted in the ops manual. This possible engine stalling while driving and possible electrical fire is a safety issue. This problem has occurred over many months throughout 2018.

Drive the Jeep approximately 10 miles on 1/18/19. Parked it in my drive way for the night. Air temp got to between 15 and 20 degrees that night. At approximately 10:30 am I started the Jeep to allow it to warm up before driving 3 miles to town. At about mile 2 I noticed a burning oil smell. I pulled off the road and saw motor oil covering my transmission and exhaust. I checked the oil and it was about 1/2 a quart low. I drove the Jeep home at that point and parked it. Called the dealership and scheduled an appointment. I was told it was a crack in the oil cooler housing assembly. Service tech explained it was a common issue with this year model and that Jeep was aware of it. When I asked about pricing and recalls the tech said it wasn't a recalled part and the total repair cost would be around $1000. Confused I called around to other Jeep owners as well as other authorized Jeep repair shops and was told this. It is a very common problem but not covered under any recall. This problem is all to common for there not to be a recall. The danger lies in the fact that had someone less knowledgeable been driving, fire could have erupted from the large amount of oil on the exhaust, engine failure due to a sudden loss of oil, and not to mention the oil that is now running onto the roadway. And the environmental issues as well.

Oil filter cooler adapter leaking and due to the placement of the unit intake manifold must be removed. Oil leaking and covering undercarriage and exhaust, appears to be a chronic and well documented problem with the 3.6 penstar engine. After a little research the unit appears to be a well known issue. Time for Chrysler to step up.

The oil filter housing on the V6 3.6L penstar failed, allowing oil to leak directly onto the intake manifold while the vehicle is running. From there the oil drained down the back of the engine, down the transmission and onto the exhaust system. From personal experience I know this to be a fire hazard. Based on my own research this failure is a known problem with this year model and resulted in the manufacturer making changes on later models. However, this does address the thousands of vehicles still on the road. Part number seems to be 68105583aa.

Oil filter/ cooler cracked and leaking oil. Jeep states I was 16days outside the powertrain warranty and will not help cover costs to repair well known issue for 3.6L pentastar engine

I recently drove my Jeep about 14 hours roundtrip for thanksgiving. I checked the oil right before because I knew an oil change was coming up, but it was still fine so I didn't worry about it. On the way home, the 'change oil soon' light came on, so I checked it again when I got home and it was completely dry! I'm not really sure how it was still running. I put more oil in it and took it to the dealer and they found a crack in the oil cooler. I hadn't had an issue with leaking until this point, but I heard others with the same type of car have had the same issue.

Started up my vehicle to take daughter to the bus. Drove 20 yards to the road to wait on the bus backed up my Jeep and shut it off after she got on the bus. Oil was everywhere. Took it to the mechanic and the oil filter housing cooler or whatever he called it was broken. Apparently from what he told me and what I read this is an extremely common problem for the 2014 model. Knowing it's a common problem and a vital piece of the Jeep functionality, why is it made of plastic and why is there no recall on it? my Jeep literally lost all oil.
