Running errands in the Jeep I started to smell burning oil while stopped with the engine idling. Returned home to notice there was engine oil dripping from transmission, driveshafts and skid plates. I traced the oil back up to the engine and then further to the top of the engine. There is engine oil and coolant pooled in the valley between the engine heads, underneath the intake manifold. The diagnosis is the oil filter/cooler assembly. Either the O-rings are bad or the plastic housing has cracked. The Jeep is out of warranty for both the bumper to bumper and the powertrain. However, the Jeep has less than 50K miles on the odometer. The repair will be done by my self as my abilities are competent and I refuse to pay $1200 dollars for a mechanic or dealership to perform this task, particularly seeing the total cost of parts is less than $250. Fca should be held responsible as leaks in the lubricating and cooling system could result in catastrophic engine failure, vehicle fires, loss of life or great bodily harm and harm to surrounding individuals, property and/or the environment. Sounds like enough to warrant a recall, if you ask me.

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.

Rocker arms were replaced at 88,000 miles and now at 110,000 they need replaced again. Oil changes done at every 3000 miles due to dusty conditions on mail route. Very frustrating several co-workers have same complaint as these vehicles are great for the job they are built for. This expense should not be a factor in considering these vehicles for purchase to work at this job..

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 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.

Vehicle stalls when started, brake depressed and shifted into reverse. Will occur several times in a row, unless brake pedal is released as soon as vehicle is shifted into reverse. When brake is released, vehicle accelerates unusually fast, in reverse, without depressing the accelerator pedal. Problem is more prominent in colder weather (below 40F).

problem #229

Feb 012020

Wrangler

  • 92,000 miles
In 2014 mopar started using a plastic oil filer / cooler housing on the 3.6 penstar engines. This plastic oil filer/cooler housing is easy to crack or develop oil leaks. The oil then puddles up under the intake manifold laying against the hot engine block. It appears to be a faulty design that could result in engine fires or breakdowns from loss of oil. This is used on lots of different models of vehicles. Mine is the 2014 Jeep Wrangler unlimited. The oil leaks anytime the engine is running. After the engine valley is full the oil runs down the back of the engine and falls on the transmission bell housing and exhaust pipe causing burning oil smell and possible fire hazard. Mopar should replace these on all vehicles after the 2014 year.

  • 86,737 miles
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.
