Took it immediately to local automotive services shop and received ABS control Module failure is now sending error to other sensors to put Jeep in limp mode and inoperable. OEM Part still on back order and unable to obtain from Jeep. I contacted Mt. Pleasant Jeep dealership service department as well and unable to get the 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.

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.

I have numerous warning lights all on at the same time and constantly chiming as I drive. These are the following lights that are all on: check engine, air bag, ABS, brake, and traction control. I have read past communication which addresses problems. I truly believe none of these issues were addressed prior to my purchase in 2020.

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 was experiencing an electrical draw, and the battery was replaced four times. The vehicle was taken to the second dealer McCord's - Dodge Chrysler Jeep Ram (990 Tennant Way, Longview, WA 98632) where it was diagnosed that the electrical draw was due to a failure of the instrument cluster electrical wiring or a failure of the electrical wiring underneath the dashboard. The vehicle was not repaired. The manufacturer was notified of the failure but did not provide any assistance. The failure mileage was approximately 46,000.

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 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"

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.

My engine light came on. We got the machine attached the code read po520 engine oil pressure sensor circuit. When we called the dealership they said it wasn't under warranty any longer and wouldn't repair. While I researched we found a technical service bulletin that was issued prior to the warranty expiration. The oil sensor should have and could have been replaced prior to the warranty expiring if the dealerships were mandated to notify and fix all repairs related to defective parts. During my research we found that the passenger side airbag is a recall in extended warranty status. Regardless if we got the extended warranty it is illegal for a dealership to sell a used vehicle with a defective airbag or a recall. It is also illegal for me not to get it fixed or my registration can be revoked. I should not be responsible for this cost to repair either of these items. I am just asking you to please take these issues seriously and to have both these parts replaced. If this wasn't bad enough, this time of year, covid and my current financial situation it makes it very difficult for me. Please help me.

Vehicle showing cel (check engine light) with no performance issues noted. Code read and shows p0520 related to the oil pressure sensor switch. After reviewing forums, determined that a tsb exists but no recall although the design of the unit has been changed due to defect. Replacing this unit took a considerable amount of time and effort as a large amount of the top half of the motor has to be removed to reveal the sensor. Replaced and vehicle has been operating free of the cel since that time and accurate oil pressure readings are being received. Without the repair, the vehicle cannot pass a nys safety inspection and features of the vehicle are disabled.
