Oil cooler keeps cracking causing oil to leak down my engine, potentially draining engine of oil while driving and catching fire. Chrysler corporate office is aware of this issue yet will not recall the part. Does it take someone getting injured or a death to occur in order to recall a faulty part? I've already had a Jeep dealer replace the oil cooler and it seems that it's going to continue to crack and leak oil everywhere down my engine. The flash point of motor oil is 232 degrees and my engine gets as hot as 230 degrees when pulling a trailer on the interstate. This is beyond frightening to think my engine could catch fire while my family and I are driving on the interstate due to Jeep faulty part.
Vehicle check engine light came on shortly after regular service at the dealer. Returned to have it checked, was told that the issue was caused by a faulty oil pressure sensor. The location of the sensor requires removal of the intake manifold, fuel injector's and rails, etc., resulting in approx. 4 hours of labor at the dealer. The dealer advised that they have "seen thousands of these sensor's fail on the 3.6 engine". there is a tsb; 18-034-14 rev. A, documenting complaints. Because the vehicle has 41K miles on it, the dealer will not cover the cost of the repair. I called the manufacturer to complain about the fact there apparently is no recall on this defective item. I was told that I could do nothing, except for put in a complaint about the dealer. I told them that the dealer is not the problem, it is the manufacturer who refuses to issue a recall despite the fact there are numerous instances of this part failing across their product line. Was told to complain to NHTSA.
While driving my Jeep on the road I noticed smoke. I immediately pulled aside and seen notor oil leak. Appareantly Jeep crysler K ow about a problem with oil cooler housing leaking. They had a back order on the part and seems to be a common problem for this particular Jeep model and year according to many Jeep forums online. Luckly I noticed smoke otherwise could have started a fire or could have caused an accident. The Jeep only has 37K miles and this seems to be when others had issues.
The oil cooler housing has cracked on my 2014 Jeep Wrangler. As per the dealership this is a part that is known to be defective and there is no reliable aftermarket replacement.

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.
Noticed what I thought was a transmission leak. After some research found that it's oil leaking from the oil cooler assembly. Vehicle was driven approximately 30 miles on the highway then returned home and noticed oil on the garage floor.
Today had issues with my Jeep smoking while driving on some trails in New Mexico. Found some oil underneath the motor near the transmission. Could not find the leak so came back and did some research and found that many Jeep owners complaining of the same issue. I found out that Chrysler/Jeep has been having issues with their oil filter/cooler housing since 2013/2014. I have also found out that they have made 3+ attempts to repair this part but has not issued a recall to have all of these replaced. From the mechanics I've discussed this with the issue is quite dangerous. The oil leaks from this housing down into the "V" of the engine between the valves and sits there with the potential of catching fire and burning the vehicle and its occupants. The mfg knows this is an issue for the last 3-4 years but is expecting the owners to pay for the defect from manufacturing. The mfg should be replacing these parts as part of a larger recall. I am currently miles from home (900 miles) and now will have to add oil every so often to ensure the engine doesn't seaze up on the way home then be out personal time trying to get it fixed.
Improper design of oil cooling unit - weak and incapable of repeated maintenance stresses. Scheduled oil change with local auto maintenance shop revealed significant amount of oil coating rear of engine, transmission bell housing, and light sheen of oil coating many components on the undercarriage. Pooled oil on the engine block at the front, directly underneath oil filter housing. Hours of internet research leads me to multiple Jeep message forums with similar/identical scenario. Every owner finds cause in faulty/compromised "adapter-engine oil filter" Jeep part number 68105583aa. Noted that this part has been upgraded/revised to an ae designation, thus revealing that Jeep knows this part to be faulty and/or of inadequate design. Vehicle was stationary (parked) when this happened, but only took note of a potential problem when I noticed an oil spot where I always park at my office, and at home. No vehicles I own have ever left an oil spot before this.
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 coolant started leaking and my three year old Jeep needed a new radiator. The garbage limited warranty from Chrysler products of course would not cover.
Arrived home in vehicle and had a strong odor of burning oil. Immediately saw a puddle of oil under the vehicle and oil on the exhaust was smoking. The oil filter/cooler housing had begun leaking. This vehicle has 44,000 miles on it and never been off road. This seems to be a very common part failure and Chrysler needs to address it. The amount of oil it lost in a short amount of time was enough to cause a fire. There was over 1/2 inch of oil in the valley between the heads and oil had blown from the motor to the rear differential. This part is conveniently not covered under the 5 yr 100,000 mile engine warranty and the dealer said the part has not been upgraded.
The contact owns a 2014 Jeep Wrangler. While stationary, the contact smelled burning oil and noticed that oil had leaked onto the ground. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 28,000.
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.
Engine oil cooler housing cracking and leaking oil. I have had it in twice in 3 months to have the housing replaced. I know of others with this year, 2014, Jeep Wrangler that have had the same problem. You can smell the oil on the exhaust and see the oil dripping under the vehicle. I have the dealer repair orders and parts replaced and they are the same both times. Now, worried it will continue to happen even after my warranty runs out and will have to pay for the repairs. Jeep should extend the warranty as long as I own it or permanently fix the cooler problem on these models.
Noticed pool of oil under my Jeep and upon closer inspection observed oil dripping from back side of engine onto the exhaust system. It appears the leak is coming from the oil filter housing, as seems to be a common failure on this model. Upon contacting the dealer about the part, I was told there is a nation-wide backorder of about 10,000 parts.
Oil cooler leak. Their should be a recall as this can potential cause a fire and everywhere I look people are filing complaints for this exact issue on 2014 Jeep Wrangler...
Purchased Jeep Wrangler as new from dealer with 103 miles on it. At 36072 oil was leaking all over the top of engine and down the transmission. Dealership replaced oil filter housing/oil cooler. After replacement I looked up part number used and it was an earlier revision than what should have used. Jeep was repaired on 2/10/17, on 2/18/17 Jeep was again leaking oil from top of engine.
Oil cooler housing leaking oil into the valley between cylinder banks. Oil then runs over the bell housing onto transmission then onto exhaust crossover pipe. Looks to be an environmental and fire issue. Started leaking at approx. 41000 miles on the Jeep.
