2014 Jeep Wrangler engine problems

The plastic oil filter housing was leaking oil onto my exhaust I had to quit driving it because of fear of a fire, so my question is : if you have oil running down and dripping of your exhaust and you guys wont recall it because you say its not a safety issue? You guys are nuts, the manufacture should be made to man up and fix this problem instead of leaving the consumer stuck with a problem that they created and an empty wallet as well, simply not fair many people have been stuck with this problem to deal with without any help from the engineers that caused it, man up and make em take responsibility if not then why does the federal safety agency even exist at all

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 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.

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.
