39 Engine And Engine Cooling problem

Failure Date: 01/19/2022

3. 6l pentastar v6, vehicle had a failed oil cooler housing. This caused the vehicle to leak a considerable amount (more than a quart) of oil into the valley between the cylinder heads, but showed no outward signs of leaking oil. This has the potential to ignite a vehicle fire during operation. Could also potentially cause catastrophic engine failure secondary to oil starvation at highway speeds.

40 Engine And Engine Cooling problem

Failure Date: 12/20/2021

Engine oil leak, front of engine, under/at bottom of oil filter housing. Loss of oil from motor, oil all over under carriage of Jeep, found first on garage floor. Jeep has 62,000 miles on it. Oil on engine, transmission, transfer case and exhaust. Unit smoking, fire hazard. No warning lamps for low oil or low oil pressure. 12.

41 Engine And Engine Cooling problem

Failure Date: 12/02/2021

Smelled burning oil coming from the engine bay. Noticed a large amount of oil under the engine. Inspected the engine bay and there was a pool of oil under the oil filter housing. There was no cel or warning. Checked oil and it was over a quart low. Oil spill under vehicle was large and dissipated in a wide area. A quick web search shows this is a common issue on the Chrysler pentastar 3. 6 engine. It is the oil coolant housing assembly which is faulty. This causes oil to spill out and drip on the transmission and exhaust which causes the oil burning smell. There was a backorder on this part and I was informed that over 65k parts were manufactured and sold this past year which demonstrates that this is a known issue. Attempted to have dealership repair but could not book a date for months due to backlog and lack of availability. Took the vehicle to an independent shop that was very familiar with the issue and confirmed it was the oil coolant housing assembly without me mentioning what I thought it was. This was a $975 repair. Contacted manufacturer and they said they could not assist me as I need to take the vehicle to the dealership (only). However, I can't be without my vehicle for 60 days until they are able to "fit me in". Concerned about the burning of oil on the exhaust from a safety/fire perspective.

42 Engine And Engine Cooling problem

Failure Date: 12/01/2021

Concerning all Jeep Wrangler vehicles with the pentastar 3. 6l v-6 engine. These engines utilize variable valve timing with dohc’s. Jeep dealers and owners are aware of a very common issue with bearing failures in these assemblies, resulting in damage to the camshafts requiring replacement of all 4 camshafts, 24 hydraulic lifters and 24 rocker assemblies. Approximate labor for this work is $1,220 plus parts cost of approximately $2,770. The issue is signaled by a loud tapping noise from one or both engine banks and typically occurs around or shortly after 80,000 miles though there are a number of reports that can be found where this issue appeared earlier. Jeep technicians diagnose the issue using a stethoscope and automatically assume all components will require replacement without further disassembly or investigation. An internet search will indicate just how prevalent this issue is. My vehicle is currently in the shop and I am told there are currently a total of three Jeep Wrangler unlimited vehicles in said shop with the same issue.

43 Engine And Engine Cooling problem

Oil filter assembly (fca pentastar 3. 6l) started leaking oil and poured out over the back of the engine and got on the rear tires causing a loss of control of the vehicle. No warnings were indicated and the event occurred where my wife and others could have been hurt or killed.

44 Engine And Engine Cooling problem

Failure Date: 09/30/2021

The contact owns 2014 Jeep Wrangler. The contact stated that while the vehicle was running there was a ticking sound coming from the engine. The contact stated that there were no warning lights illuminated. The vehicle was taken to an independent mechanic to be diagnosed. The contact was informed that the engine needed to be replaced. The manufacturer was contacted and informed the contact that the vehicle was not covered under an unknown extended warranty. The contact was referred to NHTSA for assistance. The failure mileage was 98,000.

45 Engine And Engine Cooling problem

Failure Date: 09/30/2021

The oil filter and oil cooler assembly is plastic with plastic gaskets. It will often crack, or the gaskets will shrink/crack over time, particularly in cold weather conditions. This causes oil to leak down onto other components, specifically the transmission, transfer case, etc. In the case of an accident this oil leak and oil soaked components can represent a fire hazard. Also can become an engine oil overheating issue as the oil cooling is not working properly. Repair requires complete disassembly of the air intake system and manufacturer only supplies the same faulty plastic parts. Repair is extremely costly and it is a known defect that has caused many parts shortages.

46 Engine And Engine Cooling problem

Failure Date: 09/14/2021

Issue with lifters ticking at 49k miles.

47 Engine And Engine Cooling problem

Failure Date: 09/01/2021

This is another complaint about the oil filter and oil cooler assembly problem that's known on the 2014 Wranglers. It's made of plastic (that cracks) with plastic gaskets (that shrink/crack over time). It's a known problem, has been reported by many, especially for vehicles in cold weather areas. Due to the location of the oil cooler assembly, it can't be easily replaced without spending over a thousand dollars and then the dealers don't stand behind or warranty the new part/their install because they know the replacement is just plastic and going to crack again. Oil leaks all over other engine components (transmission, transfer case, etc. ), which could cause the vehicle to catch on fire; an accident due to the leaked on components being deteriorated and not working properly from being oil soaked; or cause the engine oil to overheat since the cooling assembly isn't working correctly. Repair requires complete disassembly of the upper engine and the oem replacement is just another faulty plastic parts. Repairs are extremely costly if you can even find parts. Oem had to know about this issue---plastic parts are never good and hopefully no one will get hurt because you could be driving a long time before you even know you have a problem.

48 Engine And Engine Cooling problem

Failure Date: 08/26/2021

I was driving the vehicle at 30 miles per hour and the engine accelerated to 60 miles per hour on it's own. Before I could get it to stop. This occurred on 4 different occasions of the vehicle accelerating on it's own. The vehicle was only able to get under control by stepping on the brake hard placed the vehicle in neutral and shut off the key. Some one could of been killed. No dick Chrysler Dodge stated they would have to drive it to see if there was an issue and charge an outrageous amount of money to determine if there was an issue. I know there is an issue. No one has inspected it as there was no accident there were no warning signs that came on. The first occurrence of the issue was on 8-.

49 Engine And Engine Cooling problem

Failure Date: 08/16/2021

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.

50 Engine And Engine Cooling problem

Failure Date: 05/10/2021

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.

51 Engine And Engine Cooling problem

Failure Date: 03/22/2021

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.

52 Engine And Engine Cooling problem

Failure Date: 03/11/2021

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.

53 Engine And Engine Cooling problem

Failure Date: 02/20/2021

Tl the contact owns a 2014 Jeep Wrangler. The contact stated that due to the cold weather, the oil cooler fractured while stationary and parked in a parking lot. The vehicle was not diagnosed nor repaired. Neither the dealer nor the manufacturer were notified of the failure. The failure mileage was approximately 109,000.

54 Engine And Engine Cooling problem

Failure Date: 02/11/2021

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.

55 Engine And Engine Cooling problem

Failure Date: 01/06/2021

Oil filter housing is cracked. Upon talking to the dealership, they said this is a known and frequent issue.

Motor oil lik.

58 Engine And Engine Cooling problem

Failure Date: 10/06/2020

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.

59 Engine And Engine Cooling problem

Failure Date: 09/07/2020

Crack in oil filter houseing.

60 Engine And Engine Cooling problem

Failure Date: 09/03/2020

I was driving down road and lost power like it dropped into neutral. Pull over to side of the road and by time I stopped had smoke coming into the cab. Got out and saw flames in engine compartment. Called police and fire but vehicle was total loss.

61 Engine And Engine Cooling problem

Failure Date: 08/01/2020

The oil filter housing was cracked and leaking and replaced under warranty a few years back. The same problem is happening again because it is a plastic oil filter housing. Chrysler knows its a defective part. Make them issue a recall please we shouldn't have to pay 800 plus to have it fixed with the same defective part. They're profiting from their mistake.

62 Engine And Engine Cooling problem

Failure Date: 08/01/2020

Loud ticking from the left side of engine. A known problem with many model years of Jeeps. I was told I do not have the warranty any longer because my warranty for the vehicle started in 2013. If I did, this known issue would not be covered. Shop wanted 3k dollars to repair. Sound happens with car running all the time in drive or just idle. Gets louder as I accelerate.

63 Engine And Engine Cooling problem

Failure Date: 06/02/2020

There is a known issue with faulty oil coolers that a bunch of people are experiencing and Jeep should be fixing these as a faulty part. Many owners of the 2014 models and possibly other models have experienced cracked oil cooler housings.

64 Engine And Engine Cooling problem

Failure Date: 05/01/2020

Engine light on when change in oil needed @ 50%. Oil pressure fluctuates when driving 2% to 30%. Noticed oil leaks in my driveway and had it checked by mechanic. Found out it was the oil filter housing/oil cooler and that it is a common problem with 3. 6 motor also, found out the part is on back order due to a lot of customers having same issue. Found the following in my search: " attention - 2014 Wranglers have bad oil leak problems! ________________________________________ 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. If you have had an oil leak, and the dealership told you the issue was the oil filter adapter, the oil cooler or the oil cooler cover, post up here. We are going to try to get pressure on Chrysler to at least redesign the part. Part number is 68105583aa and it applies only to 2014 3. 6l Chrysler v6 engines, at least so far. Similar issues have been reported with the new 3. 2l v6 used in the cherokee, but it apparently has a different part number. This is a major issue if you own a 2014 Wrangler. There is no way to know if/when the part will crack, and if it does, it is not a trail repair. The adapter is buried under the intake manifold, and ever getting to it with some putty would be nearly impossible. You had better have extra oil with you at all times if you are trail riding a 2014 Wrangler. Post here if you have the issue, and go to safercar. Gov and file a complaint. If Chrysler doesn't fix this issue, you will never feel safe wheeling your 2014 Jeep in the backcountry. They need to fix this, now. All 3. 6l vehicles are affected".

Failure Date: 04/15/2020

The lifters are sounding and can cause the engine to mal function or stop working all together. I know of 2 other people close to me that this is happening to also.

66 Engine And Engine Cooling problem

Failure Date: 02/03/2020

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.

67 Engine And Engine Cooling problem

Failure Date: 01/11/2020

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.

68 Engine And Engine Cooling problem

Failure Date: 01/05/2020

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!!!!.
