2014 JEEP WRANGLER Engine Problems

OIL HOUSING FAILED , CAUSED OIL INTO ENGINE AND EXHAUST

I was driving on I35 on 10/23/2025 when I saw a small spark then my vehicle caught fire and i exited the vehicle called 911 Lewisville Fire Department and was informed that they responded to vehicle fire on 10/23/2025 at 9:45 pm, their case number is 2025-0012175. The representative stated that the Lewisville Police Dept. also completed a report, case number 250068809.

I had repairs done to my Jeep in April 2024. At that time, I was made aware that my ABS control module was faulty and no longer functioning. I have been periodically checking with my mechanic and online to check the status of this part, only to find that it has been an ongoing issue with some models having this part unavailable since 2019. At the end of October 2025, I began having a major safety issue in which my Jeep's engine will shut off without warning and the only reason I will be aware is because the wheel will no longer turn easily (trying to turn without power steering). In addition, there will at times be a fluctuation of power either having a an extreme spike or drop in RPMs causing the Jeep to lurch while driving. The cruise control cannot be used with this issue, and I have...

Starting in approximately mid 2023 the vehicle began to leak oil. This was noted once the vehicle was parked after driving. There were various amounts of oil pooled underneath the oil filter housing on the ground. At this time it had approximately 70,000 miles. I had to consistently add many quarts of oil to keep the vehicle operating while going to several mechanics to diagnose the problem. There are many instances where a strong burning smell comes from the engine compartment especially when traveling at higher speeds (highway driving). It was determined that the oil filter housing had cracked and was the source of the oil leak. The cost for repair was approximately $800 for labor and the part, having to spend additional money to get a rental car. The mechanics stated that they have had to replace this same part on many other Jeep Wranglers that are the same...

The engine in my 2014 Jeep Wrangler Unlimited (3.6L Pentastar V6) suddenly seized without warning at approx. 154,525 miles. The vehicle stalled while in motion, causing immediate loss of power and creating a dangerous situation where I could have been struck by other traffic. This was a major safety hazard. The Jeep was towed to a dealership, where technicians confirmed the engine is seized and provided a written estimate of about $12,000 for full engine replacement. I later had the vehicle towed back to my home, but the failed engine remains in the vehicle and is available for inspection upon request. The problem has been reproduced and confirmed by the authorized Jeep service center. Jeep/Stellantis Customer Care has also been contacted, and a case has been opened.Decline goodwill assistance. There were no warning lamps, messages, or prior symptoms before the failure. The vehicle was operating normally until the sudden stall....

My 2014 jeep wrangler unlimited started throwing the motor in limp mode. Had it checked out and it's the TIPM and the wiring harness. As I dug into that some 2014 jeeps already have a recall on this. But I cannot find on my VIN. Could this be a needed recall that this jeep needs to be added too? Help please.almost caused an accident 3 different times throwing a brand new motor into limp mode

In 2020 and 2025, Oil Coolant Housing cracked and failed. First incident happened on the way to an oil change. Certified Mechanic found oil covering entire undercarriage and engine, and notified me this was a severe fire and safety hazard. Replaced with an OEM Housing from dealership. 2025, same failure. Found by another Certified Mechanic while researching check engine light. Replaced with a metal Housing. Getting a P0303 and P0305 error code. Recorded over 300 misfires in 2 days. Replaced all spark plugs, coil packs and fuel injector in #5. No improvement in performance, continued coding. While returning to Mechanic, had a strong burning smell and smoke coming out from under the hood. Coolant was covering entire engine compartment and undercarriage. Mechanic notified me the Coolant was flowing through the engine and exiting out the #5 cylinder. Diagnosed failure of head gasket and engine. Driving vehicle causes smoke under hood,...

In the 9 years I have owned my Jeep I have now replaced the oil filter housing twice. Each time has caused me over $300 just for the part, which is PLASTIC from the dealership to my mechanic then over $1000 to install. My mechanic explained to me that when plastic is heated then cold with oil it will eventually crack. This then drips on the exhaust which causes either smoke through the vents or a small fire eventually. This needs a recall.

The oil filter housing developed a leak which lead to excessive amounts of oil spilling on the exterior of the engine which could cause a fire.

Starting in March of 2024 the vehicle began to leak copious amounts of oil. This was noted once the vehicle was parked after driving. It was anywhere from the size of a half dollar to a dinner plate size of oil pooled underneath the oil filter housing on the ground. At this time the Jeep had approximately 103,000 miles. While diagnosing the issue, I had to consistently add many quarts of oil to keep the vehicle operating. During the diagnosis stage, there were many instances where a strong burning smell became obvious from the engine compartment. After consulting with two independent certified mechanics, it was determined that the oil filter housing had become compromised and was the source of the oil leak. The cost for repair was $175 for the part and $950 for labor, plus $200 for a rental. Both mechanics that diagnosed the issue advised they both had...

Engine oil cooler/filter housing. Developed oil leak by being placed under manifold. Took it to dealer, Flow, confirmed bad oil leak in item mentioned. They replaced the mentioned part. Bad oil leaks can cause engine fire. Not sure it is available for view at dealer. Cost was over $1300. Mileage was about 93000.

The contact owns a 2014 Jeep Wrangler. The contact stated while the vehicle was parked, the contact noticed a loud clanking sound coming from the engine. There was no warning light illuminated. The vehicle was taken to an independent mechanic and the vehicle was diagnosed with engine rod bearing failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 104,000.

Engine started chugging at about 30,000 miles and engine light illuminated. The engine light continued to go off and on until about 36,000 miles, at which point it stayed on. Brought to dealership and and they did a leak down test on the left side cylinder. It was found that cylinder 2 had a 65% compression loss. This engine is a Pentastar 3.6l v6 that was part of a recall for 2011-2013 models. Apparently Mopar still installed these engines in later years but are refusing to foot the bill for them. I worked with Customer Support and they flat out refused to help me.

My Jeep only has 60,000 and I already have to replace the oil cooler on it. This causes the radiator fluid to leak and overheated my car. This could cause major damage to my engine and its components. This would also cause the oil to leak into my coolant reservoir. It’s a major defect by Jeep and needs modifications.

The Jeep oil cooler will leak from factory. It will cause the engine to cease working causing the vehicle to stop. The dealer said this would happen. There were no warning signs, just the smell of burning oil.

Driving sometimes with cruise on and sometimes not or going up a slight inclined the car will lose RPM goes down and then back up. I Was merging on to a highway went to give it gas and RPM goes down and I had 2 semis coming up on me so had to pull over to shoulder. It is very unsafe because you just dont know when it is going to do it. Have had it in to dealership computer and no code. But very very frustrating. They have put computer on and drove around and of course it wouldnt do it. We are at our end of the rope we don't know what to do. Service dept just said if it doesn't throw a code cant do anything. I guess when we get hit they wiil do something.

There needs to be a recall on the 2014 Jeep wrangler oil filter housing immediately. My Jeep has the Pentastar oil filter housing used in these vehicles can crack and warp due to heat exposure and this can lead to serious oil leaks. Despite knowing about this issue, the company has never issued a recall, instead, they have discontinued the production of the Pentastar and redesigned the oil filter housing for newer vehicle models. My jeep was pouring out oil and the red oil light turned on. I immediately had my jeep towed to the dealer . They had already "fixed" this issue two times previously. It is beyond comprehension that this has not been a manufacturer recall. It is extremely dangerous.

The contact owns a 2014 Jeep Wrangler. The contact stated that the vehicle was experiencing electrical failures. The check engine warning light was illuminated intermittently, and the infotainment system failed to turn on. The vehicle was taken to the dealer, where the oil sensor pressure circuit was replaced due to an internal short in the oil-sending unit. Additionally, the PCM software was updated, and the infotainment system was replaced. The contact also stated that the fuel gauge provided inaccurate readings and would not read that the fuel tank was full. The vehicle was taken to the dealer twice for fuel gauge failure. The dealer performed a PCM software update for fuel sender recalibration and replaced the fuel pump module. The contact stated that the traction control warning light illuminated intermittently, and the vehicle was taken to the dealer, who replaced an unknown sensor. Additionally, the contact stated that the vehicle...

The plastic oil filter housing cracked. So many have cracked you can’t find one to replace it. Metal ones are being made but can’t find those either. It’s a HUGE problem and with minivans.also. They need to recall all the plastic oil filter housing units.

Oil Filter Housing cracked. Oil pools on top of engine and under intake manifold. Oil runs down the right side of engine - taking out an oxygen sensor in the process as the wiring harness gets soaked in oil. Oil ran down onto transmission and exhaust manifolds creating odor and a lot of smoke - not to mention the oil all over my driveway and street. Evidently, this is a known problem to the manufacturer. It is reported hundreds of times on this site and thousands of times on various internet sites. Clearly there are manufacturing problems that are at fault and creating serious safety and economic impacts to owners. Research across various platforms indicates that it is not a matter of "if this will happen," but "when" it will happen. Where is the accountability to the manufacturer? Why is NHTSA NOT doing something to protect the consumer and the...

Hello my jeeps oil filter housing has been repaired twice it's about 900 both times their needs to be a safety recall it smoke and causes alot of issues this is a poor design and needs attention my jeep is parked until further notice

Oil cooler cracked, very common with this engine. Needs to be a recall. My shop said they were doing around 2 a week? Poor design, plastic mounted to aluminum. It cost me $1285.00 to get this fixed. The engine only has 46000 miles on it. The vehicle has never been off-road and has the oil changed every 3000 miles.

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.

The oil housing is leaking oil on the engine and exhaust it smells terrible when engine is on , maybe a risk of fire !! Looks like to be a well know important problem at jeep . There should be a recall!! Thx Looks like jerp want 1200$ to fix a known problem!

Oil cooler broke due to being made out of plastic. I had to have a new one installed made out of metal. Labor and parts were 855.00. I don’t think this should have happened both engine and driveway are covered in oil?

Warped and leaking oil filter housing. The housing is made of plastic and unsuitable for this use. Newer models they have corrected this and the housings are made of aluminum. Mine is plastic and very unsafe. Having leaking oil is an enviromental and safety hazard. Jeep refuses to repair this issue even though it is a well know problem for all Penstar engies with the plastic housing. The leaking housing was brought to my attention during a normal oil change.

I smell burning oil in my vehicle after short or extended drives and discovered that this issue was widely reported for 2014 Jeep Wanglers. The fumes have the potential to diminish my health and should be addressed immediately.

Greetings, My 2014 Jeep Wrangler has developed a ticking sound that is progressively getting worse. I have addressed this with my professional mechanic and noted to me after checking the engine that there is an issue with the engine and Chrysler knows about it yet no recall has been published. The issue has to do with the 3. 6l Pentastar engine is notorious for having a camshaft or lifter go bad. The answer is apparently to replace the headers. I have contacted Customer service at Chrysler and they are now claiming not to know about it. My mechanic stated that repairs can run about $2000. I would appreciate it if you would appropriately deal with this and inform me on the outcome. Thank you kindly, [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

At approx 45,000 miles the rocker arm bearing failed causing a ticking noise in the engine. Upon researching this issue, I have found multiple complaints and confirmation that this issue is due to poor manufacturing.

The antilock brake module shorted out causing the line to melt and shut down my vehicle

The vehicle stalls, losing power steering and brakes in the middle of the road. It is critical to have this addressed before someone dies in a wreck. It also over heats to the point it will catch on fire.

oil filter housing unit leaks oil causing fire hazard and engine seizure, had to have repaired 2 times in a one year period.

The contact owns a 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.

Oil cool on the top of the motor failed filling top of motor with oil and spilling over in back and front. This is a very common problem that should be looked at closer could easily get on exhaust causing a potential fire.

2014 jeep wrangler unlimited Sahara oil filter housing fail twice already. Causes oil to leak all over top of engine and then drips onto other components. Could cause fire, could cause engine to sieze, no warning lights to indicate an issue.

Engine oil cooler failed. No warning lights or chimes. Problem found by smell of burning oil covering the intake valley and drainage from there onto the exhaust pipe throughout the underside of the vehicle. Can result in a vehicle fire.This is a known problem with the 3.6l jeep engine. This is a costly repair and replacement part of OEM quality or better is difficult to locate because of so many failures.

Oil Filter Housing failed leaking oil onto top of motor and hot exhaust manifold nearly causing a fire and catastrophic engine failure in heavy traffic. Dealer has confirmed this is a known issue on the 3.6 pentastar engines from after 2014. Currently replacement part has a 58000 unit back order. Failed with no warning until oil light and temp lights triggered.

After a short drive to town I could smell oil burning .. Oil was Pouring on the the ground from under my jeep. I was told from the dealer it is a common problem on that motor and it was the OIL COOLER . It was cracked on the plastic part . I had it repaired and it cost me 800$ . There were no warning lamps . If I did not catch the problem in time the motor would have locked up.. the oil hitting the hot manifold could have caught fire .

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.

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

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....

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...

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...

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.

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...

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.

Issue with lifters ticking at 49k miles

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-

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
