Oil cooler leaking

The oil cooler broke and is leaking oil all over my engine, transfer case and exhaust. Jeep says it's common and they expect me to pay $850 out of my pocket for a plastic part that will fail again. Shame on them. It was sitting in my garage and oil is everywhere on the ground. It's too dangerous to drive

Approximately 8 months ago, I had my first experience with my jku shifting incorrectly while going up & down the streets which I live on in kailua kona, Hawaii. I live on a volcano & thus the streets are at a great degree, up to 25% grade. My first experience with the transmission shifting on its own was coming up a street where I downshifted to 2nd gear....the Jeep then shifted into 1st on its own and then upshifted to 3rd, then down to 2nd & then to 1st, all on its own. I then came to a stop sign & put it back into drive for automatic hoping that it would stop. For about 2-3 weeks after that, it seemed that the transmission slipped every once in a while & then nothing. It drove fine. I never took it to the dealership from that one or two instances. On 8/5/19 I took my Jeep in for a regular oil change. Kona kwik lube looked at everything & said that everything on the jku looked great. I then had to leave town for a week & upon return from the mainland, I had numerous drops (of what I thought was oil) on the floor of my carport. I took my Jeep to repair shop for diagnostic & was told that they saw signs of oil leak from the oil filter housing, but were unable to pinpoint location of leak. As I knew the manager of kkl, I took it back there. They cleaned up the area & stated that it was not oil leak. Upon returning home, I had no leaks coming from the Jeep for 2 weeks.then the leaks started. I went back to kkl on 10/9/19 where they put dye in the engine to find the leak. On 10/14/19 they saw no dye in the engine, thereby noting that it was transmission. I went to transmission technology right after, & I was advised that I had a german transmission & the transmission pump, seals, etc. Were all leaking & it would be over $2,000 to fix the transmission. I only have 37,933 miles on this 2014 jku. At 38,000 miles, this transmission should not be leaking. Jeep declined cover.

Oil cooler/filter pools out oil because of plastic housing. This wears, cracks during routine oil changes. The oil pools and drips all over transmission housing, under skid plates and you simply lose all of your oil. No a good design, simply lazy by Chrysler.

For 2014, Chrysler made a change to a part called the "oil filter adapter" which sits on top of the engine, under the intake manifold. There are now a parade of people with various Chrysler vehicles that use the 3.6L reporting that the new part cracks, causing a major oil leak, potentially a fire, and can cause your engine to be drained of all oil. Part number is 68105583aa and it applies only to 3.6L Chrysler V6 engines. I purchased the Jeep used and now have just over 60K miles - Chrysler is refusing to cover under their "100K mile" powertrain warranty even though this is a known defect and I still have almost 40K miles to go before I reach 100K miles.

Jeep has a known epic failure is design flaw in its 2014 Wrangler when it switched from a metal oil filter cooler housing to a plastic oil filter cooler housing. Hundreds of cases of the part breaking/leaking oil all over lower engine and exhaust which is a fire hazard. My part leaked oil over an unknown amount of time because I live with a gravel driveway.....now dealer shows me "metal" like glow to oil which could be engine failure.....hundreds of cases

Oil filter/cooler housing leak. This is a common problem with 2014/15 penstar engines. Happening around 50,000 miles or 5/6 oil change. Leak causes oil to pool on top of engine and running down onto the exhaust and transmission pan. Can leak as much as.5 quarts of oil in a short matter of time. This is a $600 fix at a dealer. Research shows it is very common. Something this common should not be put on the owners expense.

At 167414 miles found clutch slipping, troubleshot to clutch being saturated with engine oil. Prior to the clutch slipping the oil filter housing cracked twice and replaced under warranty twice, suspected leak caused clutch to be saturated. Dealer place dye in oil to verify leak is fixed. Also trying to work with dealer to replace clutch at reasonable price sonce damage was caused by a warrantied part. While transmission was out also found transmission fluid leak from the input shaft seal I have asked dealer to fix this issue, but only recommended a transmission service, nothing to verify the leak and verify the input shaft is not scorned or damaged. Will take to another dealer after being checked for the dye, on the recommendation of Jeep customer service. Photos attached show oil around clutch, bell housing coated with oil and the input shaft leak.

The mechanism of what happened to my vehicle is undetermined whether it was stationary or while driving. However I noticed a massive oil leak after driving. The entire under side of the Jeep where the transmission and transfer case are were completely soaked in motor oil. After taking it to a Jeep dealership, they diagnosed it to be a leak coming from the actual oil cooler housing. Come to find out my vehicle has already passed its warranty coverage date. And after doing a little bit of research, it seems I'm not the only person who has had this problem with their Jeep, not specifically just the 2014 models others as well. Other than the complaints from individuals who have purchased a Jeep, I have yet to find any comment from mopar, Chrysler, or the Jeep manufacturer themselves addressing the issue of having a plastic oil cooler housing. Fyi its not that easy of a repair so it could be quite costly to some.

Noticed large droplets of oil under Jeep. Upon inspection, without removal of any components, looked as though oil was pooling and dripping and had been spraying back towards transmission. Issue a recall. Does it take a serious injury or death before someone realizes this is a major issue?

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. Jeep states since it is a sensor, it not covered by the longer powertrain warranty.

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.

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.

I noticed there is a leak from my oil filter housing, I could T tell why in my under carriage I had oil going back near transmission followed the leak up to the oil filter housing I am not sure if it is cracked but at only 49K this should not be happening and I have read on many threads this is any issue this should be a recall and covered under power terrain warranty. I noticed it because I was checking my differential fluids and saw the mess of oil spraying all over my under carriage
