2 Power Train problem

Failure Date: 03/12/2024

Starting in March of 2024 the vehicle began to leak copious amounts of oil. This was noted once the vehicle was parked after driving. It was anywhere from the size of a half dollar to a dinner plate size of oil pooled underneath the oil filter housing on the ground. At this time the Jeep had approximately 103,000 miles. While diagnosing the issue, I had to consistently add many quarts of oil to keep the vehicle operating. During the diagnosis stage, there were many instances where a strong burning smell became obvious from the engine compartment. After consulting with two independent certified mechanics, it was determined that the oil filter housing had become compromised and was the source of the oil leak. The cost for repair was $175 for the part and $950 for labor, plus $200 for a rental. Both mechanics that diagnosed the issue advised they both had replaced this same part on many other Jeep Wrangler jk between the years of 2014-16. While the burning smell was indicative of a possible fire at some point, one mechanic did say one other Jeep that had this part fail did catch on fire due to the oil running down through the heated engine as this part is made of plastic and situated on the top side of the engine. Fires were most certainly a life safety concern as this is my primary vehicle for myself and children. The vehicle had all of its maintenance current and properly done, there was no accident or incident to cause this part to crack other than a poor design with cheap parts. The oil clean up during the fix was extensive as it had pooled and ran into multiple locations on the engine. I did not have the vehicle inspected by the manufacturer as it was no longer under warranty and it would have cost even more to have them do the work. No warnings, not even a low oil pressure or check engine light came on. It was the burning smell and oil loss that was visibly noted that identified an issue.

3 Power Train problem

Failure Date: 09/28/2023

Oil filter housing and intake manifold had to be replaced dues a coolant leak. "common" issue on Jeep's they said. But despite knowing about this issue, the company has never issued a recall, instead, they redesigned the oil filter housing.

4 Power Train problem

Failure Date: 07/20/2023

When it first started, I would have to be going at minimum 55-60 mph. But it got so bad to the point that I would be going 15-20 mph and out of nowhere my vehicle would start violently shaking and my steering wheel would jerk side to side. The only way to get it to stop would be to completely let off the pedals and let it come to a complete stop by itself. Hitting the brakes could cause it to flip. Having to come to a stop, regardless of the location could cause a serious accident or pile up. Trying to control the steering wheel when this is occurring could cause an accident as well. This is not something that happens here and there. This incident is so frequent that there are websites that try to warn and help others bc it happens so after. Its cost me $4000 trying to fix it. Please look into this and help us resolve this issue before it costs someone their dad or mom or brother or sister, or someone their child or grandchild. Thank you for your time. It is greatly appreciated.

5 Power Train problem

Failure Date: 03/26/2022

Parts r2123503ac & 68087998aa which are available for inspection failed while driving my vehicle a day after in was serviced by the dealer. I heard a loud bang emit from under vehicle. At which point all forward motion stopped & the vehicle would not move at all when the accelerator was pressed. The engine was running and all electrical components continued to function. It stopped in the road and was not able to make it to the shoulder without being pushed. Fortunately traffic was light and the vehicles behind me were able to stop before a collision. Had this happened on the highway or at an intersection the outcome could have been much worse. There were no warning lights prior to or after the failure. I had the vehicle towed to the dealer who requested 3 hours of shop time to disassemble the powertrain. At which point I was contacted and told I needed a new transfer case. When I went to look at the transfer case I saw that the transfer case adapter and external housing was rusted and the gears were worn away. (photos) . Upon taking the part to mechanics and another dealer I was informed such wear was not a result normal usage, wear and tear. I opened a case with fca (82582111) to enquire as to how the failure occurred. The fca nor the dealer provided any explanation as to how the failure occurred. For background , the vehicle was custom ordered from the factory, and purchased new in 2014. It a had 64990 miles at the time of the failure. I'm the original owner & only driver of the vehicle. The vehicle has never been off-roaded or driven through high water. The vehicle has not been modified other than a mopar 2" lift kit installed by the dealer. All scheduled factory service , maintenance and inspections were performed by the dealer. The extent of the rusting and the wearing of the components would indicate that the issue had been occurring for some time. Yet it was not detectable without the vehicle being lifted and the transfer case removed.

The other day I was changing the fluids in my transfer case and I noticed that the cv bolts were broken and coming out my Jeep is not lifted nor is there larger tires on it. If these all snapped the possibility the drive shift my fall out. If you contact me immediately I won't proceed with fixing the drive shaft if not I'm replacing it tomorrow.

8 Power Train problem

Failure Date: 03/01/2021

At 63,000 miles my 2014 Jeep Wrangler sport 4x4 started leaking oil really bad. Looked up problems people have with oil leaks via the internet. Found out there have been more than a thousands of problems with this happening all of a sudden. Took it to a shop and they confirmed that is leaking from a cracked "engine oil cooler and oil filter housing adapter". Called around for this part and all dealers had a back order on this part and didn't know when they would be getting them in. Finally located one from a dealer in southern California through a person I knew personally that worked for a dealer. He said there have been more than 4,200 orders for this part in just southern California. This is a very big problem! this can lead to the engine catching fire. Also a very expensive cost for just the part and than they still have to remove the upper and lower intake plenum gaskets needing replacement when this part is replaced. The leaking of oil has been happening over a week or so.

9 Power Train problem

Failure Date: 02/25/2021

My oil filter housing has a leak and no one can get the part. Apparently this is happening to a lot of people as the part is in high demand. Jeep should issue a recall.

10 Power Train problem

Failure Date: 02/21/2021

Mopar oil cooler housing, which houses a cooler and oil filter, sits on the engine and has cracked, causing oil to leak out of it. Oil leaks down the engine and onto the transmission housing.

2014 Jeep Wrangler unlimited oil filter adapter assembly cracked causing oil to flow out of the assembly at the rate of 1 1/2 quarts every 2 days. It leaks while stationary and in motion. The engine could easily catch fire.

12 Power Train problem

Failure Date: 12/08/2020

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 40�f).

13 Power Train problem

Failure Date: 12/01/2020

Defective bearing in rocker arm leading to engine failure. It is a common problem with the engine on these vehicles. When engine failure occurs, there is loss of power steering, propulsion, and difficult braking.

14 Power Train problem

Failure Date: 11/27/2020

2014 Jeep Wrangler with 43,000 miles severe oil leak from oil filter housing. Oil went from small drip to severe leak with oil coating cross member and exhaust pipe within weeks. Oil dripping and coating the hot exhaust is a fire hazzard and you can smell the burning oil at every stop light. $1000 repair at the dealer.

15 Power Train problem

Failure Date: 11/17/2020

The vehicle will unexpectedly not be able to shift gears up or down suddenly due to a switch sensor located in the transmission transfer case that malfunctions due to corrosion due to lack of protection on the wiring which is exposed to the elements. I noticed this happening a few times before I had a chance to take it into the dealer repair shop. When I was on my way home from work commuting through evening rush hour, I was driving at normal residential street speeds and as traffic sped up my car did not shift gears but rather kept revving higher. I was driving along with traffic and noticed as we were slowing down it didn't downshift either. I was able to pull over and inspected the vehicle but didn't notice any wrong. I had to drive home with my hazards and at a set speed as much as possible. It was not a safe situation nor would it be good for the engine had it got pushed harder.

16 Power Train problem

17 Power Train problem

Failure Date: 06/19/2020

Radiator went bad.

18 Power Train problem

Failure Date: 03/17/2020

Oil cooler/oil filter housing and gaskets have a known defect that causes oil to leak onto and into engine components, such as the radiator, causing thousands of dollars in damage to the vehicle. Jeep/Chrysler/Dodge/ram techs know that this is a common defect, and the leaking oil can and does burn, which can lead to a total engine fire!!! I first noticed the issue when I smelled burning oil. Thinking it was just a minor issue that could be fixed whenever I had the free time, I continued driving for another week or two until smoke started coming out of the engine! I finally took it in because there was way too much smoke to be safe (fire?). The tech that worked on my Jeep, mike pollard, says he sees this issue all the time, advised me to pay for the repairs and then file for reimbursement with their corporate office since it is a known issue and my Jeep only had 43,500 miles on it (well under the 100,000 mile powertrain warranty). Well, I did as he asked, but corporate customer care is useless, will not reach out to the tech as asked, and are doing their best to not pay because vehicle is out of warranty and there is not a recall. Either way, this issue can start a fire if left unfixed. Jeep knows that this is a common issue, yet will not do a recall unless forced (money over safety). Look online at the hundreds of others complaining about this common issue. . Read more...

21 Power Train problem

Failure Date: 10/13/2019

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.

22 Power Train problem

Failure Date: 09/12/2019

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.

23 Power Train problem

Failure Date: 07/12/2019

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.

24 Power Train problem

Failure Date: 04/24/2019

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.

25 Power Train problem

Failure Date: 02/25/2019

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.

26 Power Train problem

Failure Date: 02/01/2019

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.

27 Power Train problem

Failure Date: 12/17/2018

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.

28 Power Train problem

Failure Date: 12/03/2018

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.

29 Power Train problem

Failure Date: 11/23/2018

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

30 Power Train problem

Failure Date: 11/23/2018

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.

31 Power Train problem

Failure Date: 11/16/2018

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.

32 Power Train problem

Failure Date: 10/21/2018

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.

33 Power Train problem

Failure Date: 10/13/2018

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

34 Power Train problem

Failure Date: 09/18/2018

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.

35 Power Train problem

Failure Date: 08/01/2018

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?.
