64000 miles oil filler housing cracked out of nowhere and started leaking oil all over the exhaust. smoke was coming off the exhaust into the jeep I was afraid the jeep would catch fire so i had to tow it home. this part made out of plastic is breaking on many jeeps because it is defective in design. it cannot do its job.oil leaking all over the road and onto hot exhaust is a dangerous result of this poorly designed part

Dealer reported crack in oil cooling housing. A burning oil and coolant smell starting in 2017, while under manufacturer warranty. I was concern that jeep would start a fire and began parking outside. I replace the oil cooler because I noticed a ticking sound. When I went to the dealer they informed the the engine is a total loss and needs to be replaced. Cylinders 1 and 6 failed. $8000 to replace the engine with a refurbished unit which addresses each of Chrysler-??s failed 3.6 liter motor. If this manufactures oil cooler and other engine issues, do not need to be addressed, I don-??t know what ever would need to be addressed.

My Jeep Wrangler was having significant engine issues with shaking, random noises and vibrations, and it turns out the Engine Oil Cooler had a crack in it and leaked oil all over the intake manifold/under carriage of the vehicle. Upon speaking with over 15 dealerships in Southern California, they noted that there were over 40,000 of this replacement part on back-order as of March 2020. I had to wait two months to get the part delivered, which meant I went two months without a vehicle, and then had to pay over $800+ on a part + labor on an item that should absolutely be recalled. There are thousands of posts on Wrangler Forum and other Jeep pages that share the exact same issue. Jeep has ignored this issue since 2014, and it's only occurring in more vehicles now. This part breaking can cause engine seizure or failure and should not be a cost to the customer as there is CLEARLY a nation-wide problem that Chrysler is ignoring.

Need to replace oil sensors, filter housing & intake manifold gasket set-warped. Oil leaking everywhere due to cracked housing. There have been complaints since 2014 in all makes of Jeep/Chrysler cars and they refuse to recall/fix. This is a serious danger!

It started with a small oil leak that turned into a big oil leak coming from the oil cooler. The high the temperature the more oil that would come out. This oil is mixed with coolant as well. This is not safe because you never know when it's going to crack and they will not cover under warranty or extended warranty. This can be a real safety issue because you can lose oil pressure which can cause engine to fail.

Noticed an oil spot in the driveway. Took the Jeep to my mechanic who informed me that this is a cracked oil cooler. He said that this is the third one he has seen and the second in 2 weeks. On the first one he did he said it took 6 weeks to get the part and that his customer drove 6 hours to get the part. There is a severe back order on these parts. I have now been waiting for 3 weeks for my mechanic to get the part. He was told by Chrysler that the next expected delivery would around May 3rd. That will be 6 weeks of not being able to use my vehicle. That is not acceptable. I have done some research on the internet and I am finding that this is a common problem that Chrysler has known about since 2014. It started to happen to vehicles with less than 5,000 miles on them. There should be a recall on this part. Or at least redesign and make enough parts to cover the demand. Why has this been allowed to happen? $1000 to repair this problem.

Leaking oil filter housing. It's a known problem and so widespread across Jeep that there's a national shortage of the part. I can't even get it fixed. Oil and coolant are leaking everywhere. It's a danger to my family and the environment.

Oil cooler housing is made with 2 types of material that doesn't have equal control of oil expansion when it is hot, therefore having to replace a oil cooler housing because of the plastic part of it cracked resulting to replace the entire kit. I had to replace it 3 times, but only paid once of the replacement cost. The other 2 were under warranty. I've researched that this is a known issue with Jeep part, particularly with the oil cooler housing kit. Metal and plastic should not be a complete kit to control the oil flow. Heat reactions are not the same.

Found oil all over the floor of my garage, had not driven Jeep. It has just 30,000 miles on it. Brought to dealers over 3 weeks ago, they are still waiting for a backordered part. And I am without my Jeep. Was told 14,000 on backorder-if its that bad for breakage why is this $1200+ repair is recall? I googled it and found it to be a big issue.

When are you going to make Chrysler recall the 3.6L V6 for their oil filter cooler base breaking. I'm lucky my vehicle didn't catch fire with all the hot oil running down over the engine. Thousands of these motors are in their products. And all cost $1355 to repair. Mine was only serviced at the dealer, no one else. It is a well known defect and Chrysler is still sticking it to customers for repairs. Surprised no one has died in a car fire.

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.

My 2014 Wrangler has the dreaded oil filter housing / oil cooler leak. While driving I smelled burning oil. The next morning I found oil on my garage floor and took the vehicle to the dealership. $875 to replace the part. In researching the issue on line, I discovered this is a very common occurrence as the manufacturer chose to make the part out of plastic.

Smelled a oil burning smell inside the cab. Noticed a dripping of oil on the ground. Took it to an independent mechanic and was told the oil filter housing was cracked. When trying to order the part, was told several thousand were on back order and they had no time frame to get one. I use this vehicle for work and no one can tell me when I can drive my vehicle. Totally unacceptable.

Very common problem w penstar 3.6. no parts available in usa as of 03-01-2021 mfr. Refuses to warranty. Claims oil filter was too tight, which was not.
