2014 Jeep Wrangler Engine Problems

OIL HOUSING FAILED , CAUSED OIL INTO ENGINE AND EXHAUST

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.

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.

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.

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.

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.

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.

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.
