general problems of the 2014 Jeep Wrangler - part 1

The contact owns a 2014 Jeep Wrangler. The contact stated that while the vehicle was parked on a driveway on two occasions, the contact noticed that the vehicle was leaking oil onto the ground. The vehicle was towed to seaside park service center, where it was diagnosed with an oil filter housing failure. The contact was advised that it was a common failure. The mechanic recommended replacing the oil filter housing with another model. The vehicle was not yet repaired. The mechanic referred the contact to the NHTSA hotline to file a safety complaint. The manufacturer was not notified of the failure. The failure mileage was approximately 68,000. The VIN was unavailable.

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.

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. This lack of warning combined with the engine seizure placed my safety and the safety of others at risk. I believe this issue is part of a known defect pattern with the 3. 6l pentastar engine, which has been subject to numerous complaints, service bulletins, and litigation. A well-maintained Jeep engine should not fail catastrophically at this mileage without warning.

See attached document for complaint.

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, some in passenger compartment and strong burning smell. Recommended replacing engine as complete failure is imminent and is a safety and fire hazard.

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.

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.

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 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.

The contact owns a 2014 Jeep Wrangler. The contact stated while driving 20 mph, the contact became aware of an abnormal coolant odor and a burning odor. Additionally, there was smoke coming from underneath the hood. There was no warning light illuminated. The contact drove back to the residence. The vehicle was taken to an independent mechanic, where it was diagnosed that cylinder #2 and #5 were leaking air into the cooling system. The mechanic determined that the head gasket, the intake manifold, and the front timing needed to be replaced. The vehicle was not repaired. The dealer was contacted, and an appointment was scheduled for diagnostic testing. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 95,000.

The contact owns a 2014 Jeep Wrangler. The contact stated while driving 60 mph, the fan turned on. The hot oil message was displayed and there was an abnormal beeping sound detected. The contact called the local dealer, who informed her there was no recall or warranty coverage on the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was 47,000.

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.

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 also experienced malfunctions in the traction control (I. E. Hydroplaning in a very small puddle in the road that a normal car could handle, let alone a Jeep). I have been waiting patiently for a year and a half and there are no updates available for Jeep owners, and the issues caused by this lack of parts could cause fatalities on the road or leave individuals with a very expensive, undrivable vehicle followed by the additional cost of purchasing a new vehicle. This is unacceptable for an extremely large and popular vehicle manufacturer to be unable to come to an agreement with parts manufacturers to resume production of a crucial vehicle part.

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 replaced this same part on many other Jeep Wrangler jk between the years of 2014-16. While the burning smell was indicative of a possible fire at some point, one mechanic did say one other Jeep that had this part fail did catch on fire due to the oil running down through the heated engine as this part is made of plastic and situated on the top side of the engine. Fires were most certainly a life safety concern as this is my primary vehicle for myself and children. The vehicle had all of its maintenance current and properly done, there was no accident or incident to cause this part to crack other than a poor design with cheap parts. The oil clean up during the fix was extensive as it had pooled and ran into multiple locations on the engine. I did not have the vehicle inspected by the manufacturer as it was no longer under warranty and it would have cost even more to have them do the work. No warnings, not even a low oil pressure or check engine light came on. It was the burning smell and oil loss that was visibly noted that identified an issue.

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.

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.

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.

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 make/year. The mechanic did say that another Jeep that had the same problem did catch on fire due to the oil running down through the heated engine as this part is made of plastic and situated on the top side of the engine. My Jeep is current on all maintenance and there has been no accident to cause this part to crack. I was made aware that previous models had metal housing, as opposed to plastic hence there not being an issue. By the time we figured out the source of the leak, it was no longer under warranty, so I had the work completed by a local mechanic instead of the dealer. No warnings, not even a low oil pressure or check engine light came on. It was the burning smell and oil loss that made me aware of an issue. Once again, at approximately 100,000 miles it has happened again. The mechanic I originally brought it to is out of business, but the part would be out of warranty regardless. Now I am stuck spending another approximately 1,000 to have it replaced again, with the same part that will inevitably crack again. They really need to recall and replace this part with a metal housing.

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.

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.

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 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.

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 public?.

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 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.

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.

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

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.

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, timothy delong.

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.

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.
