Problems with 2014 Jeep Wrangler POWER TRAIN

Oil cooler leaking

Transmission leaking oil onto exhaust pipe while driving. just started 2 days ago. leaked approximately 1 pint in 30 miles travel on highway. under side of vehicle covered with oil.

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

2014 jeep wrangler unlimited. consumer writes in regard to gear stick moving/slipping while engine is running. *as the consumer stated the failure occurs on a daily basis. the warranty company could not duplicate the failure so, was unable to repair the vehicle. *js

Ticking noise from the engine on both driver and passenger sides. the noise becomes louder when the engine gets warm, especially when it is close to a wall or other vehicles. diagnostic from dealership says it is due to rocker arm failures.

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.

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. *tr*jb

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

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.

40000 miles and the rear main seal is already leaking bad. happened when i first bought it in 2016 and the dealer said nothing was wrong or leaking as i was loosing oil.. now it's leaking terribly bad and they won't cover it.

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.

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.

Oil filter housing started leaking with no warning or events occurring in the area. fast research states this is a commonly know issue that jeep is aware of but avoiding.

Oil filter and cooler leaking oil all over engine and exhaust the fumes from burning oil all inside the cabine

Oil filter/ cooler cracked and leaking oil. jeep states i was 16days outside the powertrain warranty and will not help cover costs to repair well known issue for 3.6l pentastar engine

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

Wiper stopped working during a rainstorm while driving on the raod when putting on new tires noticed the seal is leaking

Our rubicon had difficulty going in reverse recently. the dealer diagnosed this that the transmission needing replacement with only 55,300 miles and just a month out of warranty. we feel like this is a defective product with so few miles. chrysler does not appear interested in addressing the issue. i have seen other issues online and wonder if this is common. hence our complaint for the record.

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?

Parked vehicle on a slope in the mountains with the parking brake engaged. the vehicle is an automatic transmission and was in park. immediately following all passengers exiting the vehicle, it slowly started rolling away, backwards. it traveled down a 4wd road a small distance before turning off and tumbling down the mountain. luckily everyone had exited the vehicle and there were no injuries. though we were parked on a slope, probably around 15 degrees, there was complete failure of both the park gear and the parking brake allowing a rollaway. the parking surfaces was a combination solid rock and dirt.

While on the highway (according to the jeep dealership) my oil cooler housing cracked and leaked most, if not all, of the engine's oil into the coolant system. this occurred in 10 minutes and extremely overheated the engine from the time it happened to the time i was able to pull off the highway and safely park. the oil mixing with the coolant caused it to turn into a thick mud-like consistency that clogged up the cooling system and after letting it cool down i opened the radiator then a thick brown oily/coolant mixture seeped out of the radiator. so the radiator was holding pressure prior to bringing it to the dealership. the jeep dealership replaced the oil cooler housing under warranty along with the radiator hoses but is now saying my radiator has a hole in it and not holding pressure and they are refusing to cover it under warranty, despite the jeep not having any mechanical issues prior to a hole blowing open in the engine and leaking out oil. the jeep dealership refuses to test the engine any further even though it ran for 10 minutes with little to no oil in it which most likely caused pre-mature wear. the jeep dealership wants me to pay $800+ for a new radiator. i bought this jeep 40 days ago from the dealership and it's still covered under the 100,000 mile powertrain warranty. they are trying to get my jeep out of their dealership as quickly as they can by spending the least amount of time and money.

My check engine light came on after driving less than 5mi. i stopped and consulted the manual. i decided to proceed home after reading it is only urgent if light is flashing. i checked my obd and it read the code p06dd which indicated a problem with oil pump. my low oil pressure light did not come on. dealership replaced a switch. shortly after my light came back on reading the same code. additionally, i smelled burning oil and car went to limp mode when at 3000 rpms. dealership replaced oil pump finally. shortly after, the car began leaking a lot of oil. dealership replaced oil cooler/housing. due to the constant problems and misdiagnosis i consulted several other dealerships and found out that they frequently see my vehicle type to replace cooler. apparently, it is due to changes made on the 3.6 engines including a plastic piece that was formally metal. the dealership i had do the repairs, claim that the switch was the problem and everything else was coincidental despite me having the code for oil pump from day 1. at approx 45000mi it is uncommon for oil system failures however it seems to be common for this make/model/year at similar milages. search forums about this problem.

Transmission supply and return steel hose rubbed on transmission housing causing the steel hose to have a hole and leak transmission fluid. hose did have a plastic bracket that broke over time.

Casting sand from the heads has contaminated the engine cooling system leading to my radiator and heater core becoming clogged with sediment.

Oil leaking from the oil filter adaptor housing per jeep service department on 2014 jeep wrangler unlimited. the item is backordered and jeep service representative advised my daughter not to drive the vehicle until it is repaired. jeep service department told us that they would not pay for rental car or provide a car while the car sits at dealership waiting for repair. no idea when part will be back in stock.

Summary: oil cooler housing cracked. this occurred at less than 51,000. we were lucky that it happened in our garage rather then while driving the vehicle. the vehicle was unsafe to drive due to the oil leak and had to be towed for repairs. if we had been driving it could have caused engine failure. covered under power train warranty but seems to be a common theme with the 2014s. request research help *bf *tr

Takata recall vehicle was in park noticed oil drops on concrete inspection under the jeep showed no leaks went to jeep forum discovered leak was at top, the plastic oil cooler was the problem, oil drips down into a v type reservoir so therefore when you take off at the reservoir full of oil now blows all under the motor. went on to jeep forum and noticed that the complaint had been done numerous times by thousands of people where the part before used to be made out of metal was now being made out of plastic so the part is faulty and needs looked into thank you

The oil filter/cooler housing has cracked and is leaking oil with less than 45,000

I noticed motor oil leaking from the bottom of my vehicle while parked. after the mechanic inspected it, it was determined to be a leak in oil cooler / filter housing after further investigation i found several car owners with the same damage in jeep vehicles below 40k. https://www.youtube.com/watch?v=srnnehjcxvy

Oil cooling housing broke and oil sprayed all over the hot engine. the smoke was pretty intense and used a fire extinguisher in case the oil flashed off

The oil filter housing has cracked at 18,000 miles

Leak from the motor oil cooler housing, on the 3.6l pentastar v6 engine from a 2014 jeep wrangler. the oil cooler housing was revised in the 2014 model year from a metal part to a plastic part. mine started leaking at 20998 miles. the leak is identified primarily by a pool of oil forming in the "v" at the base of the cooler housing, and motor oil running down off the top of the transmission bellhousing and around the transmission pan (automatic transmission). the leak is not a transmission leak, it is an oil leak from the motor oil cooler housing.

Jeep wrangler effected. 2014 with 17000 miles the oil filter/oil cooler housing failed and leaked 3qts of oil in less then 24hours. the oil was changed 5 months prior to this problem and the dealer claimed the oil filter was put on to tight which caused cracks in the housing and would not complete the work under warrenty. after the repair i requested to keep the part that was taken out. after close examination and using compressed air to see if i could find a crack there was crack to be found. only thing i could see that could cause a leak was a missing gasket on botton of house.

When car was 3 months old, i was putting gear shift into park and it pop back out and i almost was ran over by vehicle. luckily, have of my body was still in car but it happened so fast that i was parked next to a brick wall and it hit exactly when i put foot on brake. i do have repair forms from ron lewis jeep and insurance report. since then i had two minor paint peel issues.

My 2014 jeep wrangler unlimited is currently being serviced for a cracked oil cooler. the oil leak was first noticed while parked in my garage. i had taken my vehicle to a local shop and they diagnosed the problem as a cracked oil cooler. i was also told i was lucky there was no fire caused as there was so much oil. i was told it should still be under warranty. the vehicle is getting its normal services now and will be taken to the dealer tomorrow. i have googled this problem and there are many complaints of the same issue for the 2014 jeep wrangler.

Transfer case rear main seal leak as diagnosed by two different jeep dealerships (jeep of hollywood and massey yardley jeep). i have taken the car in twice for repair and the leak continues (02/24/2017 [hollywood jeep] and 03/08/2017 [massey yardley]). the car is in for reevaluation and repair as i am writing this making it the third time in three weeks the car is being repaired for the same issue (03/17/2017 [massey yardley]). this involves the motor oil in the vehicle and leaks regardless of whether the vehicle is idle or being driven. once the wrangler is driven the the oil heats up, and thins out, causing the oil to leak in larger amounts and faster. this is a safety issue because leaking oil can start an engine fire or too much oil lost can cause an engine to be damaged or even seize. jeep corporate customer service has been notified of this issue and their "case management" team has been involved in attempting to resolve the issue, however, to-date all customer service reps indicate there is no recall or investigation into these issues. as an aside, the car was taken to the dealer, by the original owner (per carfax report), for transfer case related issues 11/18/2015. i implore nhtsa to investigate this issue as this has the potential to be a life threatening issue.

The oil cooler under the intake, the jeep has 68k miles on it, needs a third oil cooler, the dealership refuses to cover them under warranty, this has been an ongoing problem since the first year i bought the jeep brand new. every time they crack, out of the blue, no warning, the driver is stranded on the side of the road with six quarts of oil all over the motor, trans, exhaust and ground.

Oil leak being caused from cracked oil housing/casing/bellhouse. similar issue amongst a large percentage of 2014 jeep wranglers

Did oil and filter change at the dealership. i got on the freeway and looked at my rear window when i saw smoke. did not think of it much since i figured its the old oil burning. drove for a good 2-3 miles and it was getting worse. pulled over to the side and a lot of smoke got inside the vehicle. got out and the oil was draining over the muffler, transmission cover that was causing the smoke. i thought they forgot to put the screw back on or the oil filter loose. called the dealership told them what happened and called a tow truck. once at the dealership, was told by the tech that it might of been the oil cooler that was draining or got cracked, he said that this is pretty common. i checked online for recalls but did not find any but i did notice a lot of jeep forums online that this was an issue with this model yr. this could be a fire hazard with all that oil draining on the muffler and the engine. bad design overall! i even know that, it doesn't take a genius to figure that out, its common sense. making parks with plastic pipes? by the engine and in a hot area? it might be to save money in parts but i am paying on a $40000 jeep. got the part 68105583aa replaced with 68105583ae. hopefully this got motified.

While driving, the vehicle, which was 3 days new to us, exhibited the classic jeep death wobble. the vehicle started to violently shake from side to side and only stopped once the brake was activated. this happened 4 times before the alignment was righted and a part replaced.

On 5/6/16 i went to start my 2014 jeep wrangler unlimited rubicon and the engine did not make a noise but the dash lit up like a christmas tree. the windows had power and radio worked but the door lock or alarm did not work. i towed it to the dealer and was advised that it was a common problem and was called the "tipm module" which is basically the entire fuse box and part of the computer. i was stuck there in north carolina from maryland for four exra days. now after getting back home to maryland on 6/5/16 i go to try and accelorate onto the highway from a ramp and the transmission revs to 5,500 rpm but the jeep will not accelerate. i have to ease off the gas and let it accelerate very slowly. thank god no trucks were coming or it could have beed and extremely dangerous situation considering it was interstate 95 by 175 where semi trucks go to the ta truck stop.

After only 2 years of highway driving my 2014 jeep wrangler unlimited started leaking oil. i took it in to the dealership and was told that the oil cooler was failing and leaking. the mechanic said that the "standard" oil filter that had been installed at my last oil change (which was done at a reputable facility) was thicker and better than the filter chrysler uses. this thicker, better filter apparently causes oil pressure to increase in order for the engine to move the oil thru this filter. a quick search online found multiple other accounts of the same part failing. the repair was covered under the powertrain warranty but i was told that if i use any oil filter other than the one they sell that if another failure occurs it would not be covered.

We had noticed an oil leak which was causing smoke & terrible smell. luckily no fire. we took it to the dealer we purchased it from, and they refused to cover repair citing that the vehicle was serviced elsewhere, therefore it was not their fault. we had it removed from there and took it to another local dealer, who acknowledged said problem and repaired the jeep under warranty. (defective oil filter housing assembly). this appears to be a well known problem, and despite the fact that this is a 2014 vehicle, the complaints seem to be excessive. there is no doubt that the dealer we bought it from deliberately tried to blame someone else even though it is a serious safety issue potentially resulting in injury and/or death. this could have easily caught on fire. we are lucky. documentation, repair invoices to follow if needed.

Automatic transmission will downshift to 2 or 3 and not up shift. requires stopping vehicle, turning off engine and restarting to return to norman operation. this happened 6 times in 1 day on 400 mile trip. happened while passing 18 wheeler on a 2 lane road. when it happens it will not accelerate. 3 videos were provided to the dealership showing the occurrence. does not set any codes.

Cracked oil filter housing. vehicle was stationary for 5 days and upon return i noticed a puddle of oil under the bell housing. the vehicle only has roughly 20,000 miles on it so i suspected a rear main seal issue. upon inspection by my local jeep dealership it was found to be a cracked oil filter housing. this is a very dangerous issue that could leave drivers stranded and could pose serious safety concerns.
