36 Power Train problem

Failure Date: 07/14/2018

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.

37 Power Train problem

Failure Date: 04/03/2018

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.

38 Power Train problem

Failure Date: 04/02/2018

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.

Failure Date: 01/08/2018

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.

41 Power Train problem

Failure Date: 01/06/2018

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.

Failure Date: 12/31/2017

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.

48 Power Train problem

Failure Date: 08/19/2017

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.

49 Power Train problem

Failure Date: 07/02/2017

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.

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.

51 Power Train problem

Failure Date: 02/01/2017

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.

53 Power Train problem

Failure Date: 08/16/2016

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.

55 Power Train problem

Failure Date: 02/26/2016

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.

56 Power Train problem

Failure Date: 11/26/2015

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.

60 Power Train problem

Failure Date: 03/20/2015

I noticed a burning smell a few nights ago before noticing an oil spill in my garage. I looked under the help and saw oil everywhere! I wasn't sure where it was coming from. It looked like maybe a seal busted from the oil pan. I took it to the dealership right away since it was still under warranty. There is oil all over the rear of the engine,I feel it will eventually start a fire! this should be recalled since there are many Wranglers and other models with the same part, having the same issue!.

I have a cracked oil filter housing that seems to be a common issue with this year model Jeep. The local dealer is about 920 back ordered which tells me that this is a major problem. Please look in to this! if this would have happened while driving it could have caused the engine to lock up and may have caused an accident.

63 Power Train problem

Failure Date: 04/27/2014

Transition & engine coolant temp immediately rose to alarm status (300 degrees) in first ever light duty 4 wd application. Off road 4wd conditions and terrain consisted of a 5% grade in low cut hay field. Alarm indicated immediate corrective action was necessary. Vehicle temperature gauges were rising from normal tolerances to alarm status in two minutes. Corrective action included cutting engine to cool. Corrective action also required blower and heater on highest settings to cool block and maintain operable driving condition temperatures. Engaging in the slightest load while 4 wheel drive train was engaged (off road) immediately replicated severe overheating condition of both tranny and block coolant. Vehicle was operable at normal operating temperatures at high speeds in two wheel drive while on pavement only. Vehicle is a 2014 Jeep sahara unlimited Wrangler with "v" 6 cyl motor automatic transmission with 2,900 miles on odometer (vehicle is brand new purchased in March 2014 - date of this report is April 2014).
