On 4/17/19, I was driving my 2014 Jeep Wrangler jk stopped at a stop light (with my window down) when I detected the odor of burning oil. I thought it was from someone else's car. On 4/21/19, I detected the odor again, and when I got home I observed oil leaking and all over the underside of my vehicle. It also appeared to be dripping on my hot exhaust which is a fire hazard. I took the vehicle to my mechanic and he said it's due a cracked plastic oil cooler housing, it's going to set me back a lot of money, and the issue may happen again. I'm lucky that the oil did not catch on fire. I've done research online and see that numerous 2014 Jeep Wrangler have this oil leakage due to design flaw utilizing plastic parts.

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.

Oil cooler housing leaking oil at 30,000 miles

- Garnerville, NY, USA

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.

I have the 2014 Jeep Wrangler with only 47000 miles. I have kept excellent care of this vehicle and it is used only as daily driver with no abuse whatsoever.just within the month of 2/2019 a code; P0305 misfire developed with the typical penastar engine "knock" and idling rough. Also, the last week of 2/2019 there was a large oil spot on my garage floor due to an oil cooler/oil housing leak. We immediately contacted the service supervisor at the dealership who stated that this has been a common occurance and the oil cooler/housing unit is replaced often. How it is possible that Chrysler can allow this? at 47000 miles this should never happen and is enexceptable.until this extensive repair is completed the vehicle is is rendered useless and my job is now interrupted. Now in addtion to the misfire I now have this huge oil leak to contend with; please refer to the picture attached of the oil stain that was discovered on my garage floor.... the entire bottom of the of my transmission/bell housing and cross member covered in oil. Moreover I just received an letter informing me that the passenger side air bag also is recalled and I have yet to address this as well. I will never purchase another Chrysler product again. I can't tell you the level of disappointment and betrayal I feel for buying an "american made" car. I hope Chrysler/Fiat corperate is enjoying short changing the consumer buy using inferior and faulty parts to save money and rip off the consumer this way. I am sure no one cares and I am just wasting my time but this should be noted and people made aware.

Engine light is on do to oil pressure sensor. From everything I'm reading this is very common in the Jeep Wrangler. Why isn't this recalled. I was quoted $600 to get this fix. I am told not to drive this as it could ruin the engine.

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.
