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.

2014 Wrangler has known faulty oil pressure sending unit sensor as there was a tsb on July 15, 2014 stating such. Tsb # 18-034-14 rev. A and rrt 14-046. 1,000 miles short of the 3 yr, 36K mile warranty, but 6 months past the 3 year and Jeep wants $411 to fix their known problem.

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.

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.

Noticed oil on my driveway two months after a routine oil change. Took to the dealer and the oil filter housing was cracked. Jeep only had 41K miles on it, resulting in a $1050 repair cost to replace. I normally take it to an oil change place (mr good lube), but they refused to work on my Jeep this time since they were aware of this oil filter housing issue (and I am guessing have been blamed). I took it to my normal mechanic instead for the oil change. Two months later, the oil started leaking so was forced to take it to the dealer.
