7 Engine Oil Leaking problem

Failure Date: 02/16/2021

I noticed a large puddle of oil when moving vehicle from parked position. There was no indicator on vehicle that it was low on oil. When checking the oil level in the vehicle, there was none showing on the dip stick. All oil had leaked out of vehicle. We had the vehicle taken to a local dealership. We were told that this is a common problem with this year/make/model. It was the oil filter housing defective releasing all oil from vehicle. This part is on national back order and not expected to be available for 45 or more days. This tells me that it is a problem with the manufacturing of the vehicle. What if I had not noticed the oil that had leaked out and my the engine lock up while driving on a busy highway.

2014 Jeep jk Wrangler. Oil filter housing crack. Oil leaking everywhere under the vehicle. Vehicle is smoking. This can cause a fire hazard. Looks like for years this has been reported and nothing has been done. This fix is almost 1000. 00 dollars. This is absolutely ridiculous that you have so many complaints and this is a know issue that the company is not willing to fix this. I will be contacting an attorney if this is not resolved by the manufacturer.

Oil filter housing leaking quarts of oil. This is a fire hazard because of where it is located. I have seen 1000,s of complaints regarding this.

14 Engine Oil Leaking problem

Failure Date: 10/28/2020

My 2014 Jeep Wrangler jku has 86737 miles and developed an oil leak. I took it to the dealer for diagnostics/repair, and was told "massive leak from oil cooler has saturated engine block valley and spilling over on to transmission and under body". As stated from the dealer, the oil leak does not drain from the engine, but pools in the engine block valley until it fills and then runs over the rest of the transmission/engine. This creates a fire hazard. . As stated from the dealer, the oil filter/cooler assembly (mopar part # 05184294ae) is located in the engine block valley, so it is very protected from external damage. The seals just leak. This defect cost over $1000 to repair. From the number of other occurrences I have read about, there should be a recall on this issue.

The mechanic advised that this is a common failure on 3. 6l pentastar v6 engines and the the only fix is a replacement of the part at a cost of $830.

17 Engine Oil Leaking problem

Failure Date: 08/03/2020

The oil cooler/filter housing is leaking oil. This is a common issue on the 2014 Jeep Wrangler as evidenced across ownership forums and websites. The vehicle only has 63,000 miles and is driven on normal city/highway streets. All normal maintenance has been done on time at dealerships. I feel that a recall should be considered for this part due to the volume of repairs and the numerous re-designs that Jeep has performed on the replacement parts. The redesigns signal that Jeep knows there is an inherent design issue that leads to failure.

18 Engine Oil Leaking problem

Failure Date: 06/12/2020

I was just starting a drive home when suddenly my cars "check engine" light came on and it refused to go higher than 3rd gear. Within minutes, my engine was starting to overheat. I was lucky enough to coast into a nearby auto repair place for them to check things out. Their diagnosis was that my oil cooling housing cracked and has been leaking oil everywhere, including the undercarriage (which I'm told is a fire hazard). They also said it's a very common problem with the 2014 models and they're shocked Jeep hasn't issued a recall on it. I later did some reading and found hundreds, if not thousands, of other people who have had the same problem. A recall should be issued for this faulty part instead of making all of us pay $750+ to fix it.

19 Engine Oil Leaking problem

Failure Date: 05/29/2020

I own a 2014 Jeep Wrangler unlimited sport. Went for my oil change at the dealership and they told me I need to replace the oil cooler assembly because it cracked and is leaking oil and the engine oil is pooling in the pan. At the tune of $1200. I went home and found this is manufacturing defect with hundreds/ thousands have this problem with their 2014 Wranglers. I see just a few who had this covered under warranty but not without a hassle from dealerships. Most, like myself are told it's not covered. 5 year/ 100,000 mi. Now 6 years. I believe I've had this problem for awhile but now after warranty expired it's brought to my attention. The problem lies with a piece changed from metal to plastic. It cracked and will be replaced with another plastic piece that will most likely crack again. If that's not bad enough, I see it's also a safety hazard! hot oil pooled in the bottom pan and on the engine has caused fires. Jeep on their own hasn't made the oil cooler crack a recall. No surprise there. But it's time they need to be responsible for this manufacturing defect ! look at how many have this same problem! please!!.

My vehicle is well maintained. Oil leaked all over the engine and onto my garage floor from a faulty engine oil cooler & intake gasket set. This was a very expensive repair that I can't afford.
