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. My mechanic (small shop) fixes this same repair 2-3 times a week. That is ridiculous and something needs to be done to reimburse jeep wrangler owners that have a huge oil spills to clean up.
2014 Jeep Wrangler engine complaints
Page 6 of 12: complaints 131 to 160 of 330, newest first, as owners wrote them.
Oil adapter housing cracked for the second time in 6 months. 1st time caused external leak and it was replaced.this time cracked again but internally causing oil to leak into coolant. Caused $3200 worth of damage and had to have coolant system replaced as well as heater coil and hoses. I know of 7 other jeep wranglers this has happened to recently.
Cracked "oil filter housing adapter." causing oil to leak all over the bottom of the engine, could potentially start a fire.
Noticed oil on the garage floor in january 2020. Engine is leaking oil from the oil cooler that is on top on the engine. Could be a fire hazard as oil drains down the back of the engine. Vehicle has 86000 miles on it but has been leaking for a while. Now it is leaking very bad and can smell burnt oil when driving. Looking on forums online and many 2014 to 2016 3.6 engines have this issue. Issue seams to be from faulty gaskets and in some cases cracked housings on the oil cooler. Mine is no longer covered under any warranty. I thought it was from the oil pan gasket at first, but when I started to smell oil burning, I started looking closer at it and found oil laying in the valley on top of the engine.
Oil cooling filter housing cracking/leaking on 2014 model wrangler jku. Eep 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
There has been many complaints on a rear main seal leak. My vehicle is not even close to 150k miles its barely at 90k and already having a leak issue. I was reading online that certain jeeps right at 16k were having the same issue. This is costly and it is extremely uncomfortable that my vehicle goes from being good to drive to hey now you have a rear main seal leak and it will cost you around 850 plus dollars. It leaked oil in my driveway and now I have to pay someone to clear that up.
Jeep started leaking oil at 57000 miles oil leak was due to a known part failure the oil housing which is plastic and can easily crack. Vehicle has only been serviced at dealership where it was bought. Oil housing located under manifold, oil leak can potentially cause a fire when it splatters on manifold. Jeep knows this part can fail at any time.
Oil cooler failed and caused complete disspursment of oil while driving. Oil leaked all over the underside and rear of vehicle. This could casue an accident or fire in the engine bay. Replaced in october 2019. Worked till feb 2020 now it is loeaking and the reservoir for oil cooler is showing pooling... Again. This part is made of cheap non heat managable materials. It needs to be recalled. This replacement is not cheap or an easy task.
Oil filter adapter cooler on top of the engine, leaking, filling the valley with 2 inches of oil in some places. Could cause fire and oil spilling over the exhaust. Oil runs down the bell housing down the transmission and across the crossmember. When you stop you can smell biting oil, due to this issue.
Tl* the contact owns a 2014 jeep wrangler. While parked the contact detected oil leaking from underneath the vehicle. There were no warning lights illuminated. The vehicle was taken to an independent mechanic who stated the oil cooler filter housing needed to be repaired. The vehicle was taken to ourisman chrysler dodge jeep ram 12430 auto dr, clarksville, md 21029 (410) 988-8100 where diagnosed the oil cooler filter housing needed to be replaced but was not repaired. The manufacturer was contacted but no further assistance was provided. The failure mileage was 66,000.
Same as alot of other people's complaints and I'm very shocked that there is not a recall for an issue that is such an on going problem, my oil cooler is leaking once again on my 2014 jeep wrangler jk and I've already spent hundreds of dollars to fix this issue and now going through this once again it is straight bull crap. I was driving down the road and came to a stop light and noticed a ton of white smoke coming from underneath my hood and I though no way not again but to my surprise I was right oil was sitting in the valley right underneath the black oil reservoir. The date below is when I notices it for the 2nd time...1/15/2020
The check engine light came on and it decodes to a cylinder misfire. I took it to the dealer and they said the cylinder had low compression. It is out of warranty and they want to charge me well over $2000 to fix it. I am reporting this because I found out this is a common problem in these engines, so much so that chrysler issued a tsb on it, however the tsb only covers up to 2013 and mine is a 2014. Apparently they thought they fixed it, but perhaps they didn't get it quite right, or didn't cover enough years. See chrysler jeep tsb 09-002-14 for reference. Please note while this issue did not cause an immediate safety concern, my research indicates that not fixing it promptly will cause un-burnt fuel to pass through the engine which is likely to cause catalytic converter failure. Due to the extreme expense to fix this known issue, people will be unwilling or unable to pay to get it fixed right away, and that in turn could lead to various safety risks, not to mention pollution controls issues.
While driving I observed smoke was coming out from my vehicle engine compartment with the odor of burning oil. I was just around the corner from my house so as I pulled into my driveway I looked under my vehicle and noticed oil dripping from under the engine on to the exhaust pipe. I am aware that 2014 jeep wranglers have a problem with the oil filter housing cracking over time. I opened my hood and looked at the oil filter housing and there was oil all over the top of the motor. I went to my local jeep dealer and was told that this year wrangler has a big problem with this and that there is no recall. I don't understand how a safety issue like this that mopar has not been called on the carpet for a fire hazard like this and that they are aware of the premature failure of this part. I was told the repair would be roughly $600. Could you help me resolve this issue and what appropriate action I can take. My vehicle only has 35,000 miles on it. Not to mention my driveway is a mess :(
Oil cooler had a major leak oil on top of engine was easily a quart. Rest of the oil had traveled down the transmission and covered almost the entirety of the engine compartment and exhaust. I noticed the leak by a strong smokey oil odor as the oil hit the exhaust. The oil cooler was replaced and must have also caused a leak in the coolant because the reservoir was near empty. Waiting to see if that was the cause of the coolant leak.
I own a 2014 jeep wrangler jk with 47800 miles. The engine oil cooler has failed and covered driveway with oil. This is a known problem that they choose not to fix. Do not buy this vehicle
The oil filter/cooler housing is known to leak allowing oil to run down engine onto exhaust causing a fire hazard.
I recently had a change oil indicator go off, earlier than anticipated. While performing the oil change, I realized there was oil all over the bottom of the vehicle, especially on the bottom of the transmission. I cleaned up and performed the oil change. Two days later the same thing. Fresh oil everywhere. Upon further research and a trip to the dealer, the conclusion was a bad oil filter adapter assembly. This is beyond common on a 2014 wrangler. Insane that there has not been a recall on this part. Come on jeep, get it together and take responsibility. I love my jeep. But right is right. This is beyond a big fire concern!!!!
Oil cooler / filter housing is leaking oil down transmission an onto the exhaust. Caused smoke and nauseous fumes to enter the cabin. Fire hazard!!!! Noticed the fumes while driving. Inspected the undercarriage a found oil leaking down transmission onto the exhaust. Inspected engine bay and found the oil pooling around the oil filter/cooler housing.
My oil cooler went out at 40,000 miles which I believe caused my head gasket to blow.
No oil pressure and check engine light on,noise from the engine lifters knocking now the dealer shows me dirt on the intake manifold cover and that is way the engine seized. The oil sensor not working I said.
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.
There is oil leaking from under my jeep and a burning smell that smells like burnt tires. I was told it could be the oil housing leaking. This is unacceptable and very dangerous.
Oil leaking from the oil cooler. I noticed oil on the transmission and upon further investigation I found the leak coming from the oil cooler below the oil filter housing. Vehicle has 56,000 miles on it
Oil filter housing is leaking, causing copious amounts of engine oil to leak over the engine and transmission and dropping down on to engine exhaust causing it smoke and emit noxious fumes into the vehicle cabin. Potential for fire is extremely high, I had to pull over and exit vehicle due to the amount of smoke coming into the cabin from the underneath. Upon investigating I initially thought my transmission had blown a line because of how much oil was coating the undercarriage of the jeep.
The engine oil cooler assembly is leaking a large amount of oil into the "v" of the engine and dripping on to the exhaust manifolds. The vehicle was parked for over a week and upon driving smoke with the smell of burning oil filled the passenger compartment. To the extent that the vehicle needed to be pulled over and inspected for fire and damage. It was noted that the transmission, frame rails, and exhaust pipes were covered in oil and the vehicle was approximately 2.5 quarts low on oil. No prior signs of an oil leak were present before the smoke and burn oil smell was noticed during normal use of the vehicle.
While driving noticed an oil burning smell, got home and looked under the hood and found a pool of engine oil. Found out from owner of the same car that a broken oil cooler assembly. This could have cause the car to burn- very dangerous indeed. Happens in lots of chrysler's vehicles
Another 2014 jeep wrangler owner with a cracked oil filter housing/cooling assembly. Oil is spilling out all over exhaust. Certainly a fire hazard. With as many complaints with this particular part that I have seen all over jeep forming and on the federal safety agency site I am surprised that chrysler has not taken any action but is leaving this to their owners to rectify.
The oil filter housing adaptor is defective. It is plastic and when it cracks it dumps oil directly onto the exhaust, which can cause a fire
Massive oil leak at the oil cooler housing. (2 quarts per day). Leaking on the top of the motor and leaking down the back passenger side engine directly over the hot exhaust manifold. Leak occurs at all RPM ranges and leaves massive puddles of oil everywhere I go which is not good for the environment. And presents a fire hazard if stuck in traffic and engine temps rise enough to cause ignition of leaking oil over a hot exhaust manifold.
