Check engine light on, OBD codes P0016, P0390, P0394. Replaced camshaft and crankshaft sensors and problem still persists; limp mode up hills, and oil loss. Per MULTIPLE Jeep Wrangler forums, this is a very wide-spread Jeep phenomenon. Dealers do not know how to fix this. Jeep needs to own up to this defect.

I have a 2015 Jeep Wrangler with the Fiat Chrysler's 3.6 liter V- 6 Pentastar engine. The Jeep has only 44,465 miles on it and now has apparent design and manufacturing defects on the engine's left side, its the Pentastar Tick. The Tick Tick Tick is very loud and the engine will shudder, its only a matter of time before the engine shuts off on the highway when I am driving causing an accident. My dealer Hollywood Chrysler Jeep estimated repairs - need left side cams and full set of rockers - oil filter housing is leaking replace - replace abs sensor - coolant flush - carbon fuel cleaning -fluids service total $6,000.07 invoice # 584685. It looks like the cylinder head, gasket, cams, lifters and rockers need to be replaced. Chrysler needs to disclose these defects. Yes my jeep is available for inspection.

Apologies if this complaint is a repeat, but I keep getting a submission error notice whenever I try to submit this form. The Jeep 4.0 liter six cylinder engine has a known defect with respect to the rocker arm bearings that causes a loud ticking noise in the engine and failure of the exhaust and intake camshafts. This happened to our 2015 Jeep in January 2020 when it had only 31,000 miles but was one month out of warranty. Chrysler did fix it at that time as a courtesy subject to a $100 fee, and a copy of the invoice for that repair is provided. Unfortunately, a little over one year later, and with less than 10,000 miles having been driven since the initial repair, the same problem has reappeared. The dealer is now claiming the problem is with the remaining rockers that were not replaced, as it is Chrysler's policy to only replace the rocker arms and camshafts that are damaged at that time. The service manager at the dealer says that they "see this all the time" and that they try to get all the rocker arms replaced when doing any repairs, but Chrysler does not allow them to do so. Of course, Chrysler is now refusing to cover the repairs, even though this is a known problem and should have been fixed the first time. This is totally unacceptable, and Chrysler should be forced to do a full recall of all affected engines and pay for all required repairs. There are thousands of complaints about this problem online, yet Chrysler still refuses to correct this problem.

Noticed significant knocking noise coming from engine that continued to get louder. Took to dealer for a nice 2 thousand dollar fix. Dealer replaced right side lifters, rocker arms, and both cam shafts. This sounds way too much like the 2011-2013 issue that Jeep "fixed" and was under warranty for those it sounds like. Very coincidental and I am not the only one with these issues based on Jeep forums

Cel on scan for code PO302 cylinder 2misfire. R&R spark plugs, ignition coil, air filter, upper intake gasket & clean throttle body. Perform upper induction cleaning. Found misfire to return only on idle on cylinder 2. perform compression test. Compression spec ok. Replaced plugs and coil again. There is a slight tick from cylinder 2 valve train area. Recommend going to dealer. Dealer: Engine does have a slight tick. Performed a compression test and leak diwn test. Found liw compression and an 80% leak on the exhaust side of cylinder 2. removed the cylinder head and found the exhaust valves burnt and excessive play in the valve guides. Replaced the left cylinder head, rocker arms and lifters. Cleared codes and road tested vehicle. Misfire no longer present. This is on a 2015 Wrangler sahara unlimited with only 51,892 miles.

Started out with oil in the air filter, had the pvc valve and cam shaft replaced. Still got oil so an oil catch can was installed, then check engine light came on (air flow filter). This was causing my engine to not be able to accelerate beyond 70 mph. They changed the sensor, but again, was unable to go over 70, and on an incline would drop down to 60 and could go no faster (no engine light this time). Next day got it up to 78, engine light came on, and again could not accelerate beyond 75.

The contact owns a 2015 Jeep Wrangler. The contact stated that while operating the vehicle there was a odor of burning oil present and smoke was seen coming from under the hood. The vehicle was taken to an independent mechanic who diagnosed that the plastic oil cooler had cracked causing oil to leak. The local dealer jacky jones Dodge located at 2840 us-129, cleveland, ga 30528 was notified of the failure and the contact was informed that the oil cooler part needed to repair the failure was on back order. The manufacturer was also notified of the failure. The VIN was not available. The failure mileage was 44,000.

Oil filter/cooler housing developed a leak. Was told by mechanic that it is most likely cracked. Replacement part is on indefinite back order, at least 45 days. Leak is bad enough that I can not safely drive the vehicle. It has been sitting in the garage for 4 weeks.

- Holt, MI, USA

Oil cooler leak. I lost over 2 quarts of oil after a short drive. The seals were also leaking into the injectors causing multiple cylinder misfire codes and check engine light warnings. No warnings from the oil cooler except the large puddle of oil under the Wrangler and oil coating the entire back of the engine and skid plate.

Jeep 2014 and older are issued a part called the oil cooler/filter housing which is prone to leaking oil on all Chrysler engineers using this part. This is defective and or a design flaw resulting in replacement and costly repair and is a reoccurring failure on all Chrysler using this part. This failed on my Jeep Wrangler with 48K miles. The part is approximately $300 to replace and over all repair at a non dealership is upwards of $1000. This issue needs to be a recall!

- Katy, TX, USA

Oil cooler assembly has started leaking badly after 60,000 miles and is a fire hazard. This assembly is too fragile and requires taking off the intake manifold to access and replace, so it should not be a plastic part. It contains the oil filter which causes it to have torque applied every oil change and causes it to break prematurely. This is very common problem and I was told by the dealer that there were 25,000 of these assemblies on back order nationwide and he could not tell me when it would be in stock. My Jeep is now undriveable until the backlog is worked through which may take months. If this was a rare problem I could get the part and have it repaired. This problem has rendered my vehicle unusable. This is unacceptable and Jeep has known about this issue for years on multiple year models. Please investigate. There is no reason this couldn't have been properly engineered with a metal part.

I I will be driving and the car will go out of gear and looses power. I have to stop, turn it off and start again for it to work. This has happened 5 times in the last year.

I was driving my keep and started smelling oil and had smoke coming from under my car. I notice on my garage floor large oil leak. I picked up my disabled son and noticed it had gotten worse. I was forced to stop by my mechanic and was told my oil cooler adaptor housing was broken and leaking badly. I had purchased a mopar protection plan directly from company. When I called Jeep dealership they said I would have to bring it and let them diagnose it before they could decide if it was covered by my mopar care plan. My mechanic informed me that this was a common problem with this Jeep engine but they had not done recall yet. I call mopar and they would not authorized payment to my mechanic unless he call for authorization number. He called and they said no. This part needs to be handled by a recall if it's that bad. I was reading complaints on another site and they said it could lead to a fire starting because of oil leaking onto exhaust.

I get frequent oil changes and I noticed that the last two oil changes it started making this ticking noise. I brought it to my mechanic and he told me that after the next few oil changes it should go away. Than my other mechanic that heard this ticking noise said that it was serious and this has something to do with an engine part callled a lifter. I nervous when he told me that if it's not fixed the engine could seize. I just bought this Jeep from a dealer not knowing this was a common problem among Wrangler. I did my research and came to the conclusion that it has nothing to do with the mileage but more so on how the engine was built. I spoke to number of dealerships and they fix this common problem on all ages and mileage Wrangler. The estimated cost of repair would range from $2000 and up. I don't think we as consumers of this product should be repairing an engine problem from Chrysler. I don't have any pictures yet til the dealership opens up the engine

Arm rockers in the injun constantly have to be replaced. Giving the injun a knocking song.

- Bronx, NY, USA

While driving the Jeep shuts off. It is hard to steer and happens without warning. This has happened about 10 times in the last month. It does not throw a code so the dealer can not fix it.

- Lehighton, PA, USA

My car is as 54090 miles, dealership changed housing thermostat and replaced the thermostat housing adaptor. Stated my car has internal engine noise from worn rockers and lifters. Was safe to drive. Got a second option, my car has rocker noise coming from the right bank and can wear. Also some cylinder heads had to be replaced. This was an issue with the 2012 and 2013 models so Chrysler should be taking these issues seriously and extended and recalling all 2015 Jeep to do a maintenance check. I was told upon my independent review not to drive my car, to get it home safe and slow. I have reported the dealership to the BBB and filed a claim with Chrysler. This needs to be taken seriously.

Radiator leak, with less than 70K miles the hoses were replaced but still leaking with smell of antifreeze

- Stafford, TX, USA

First owner of vehicle. Issues began with engine light appearing/blinking & vehicle struggling to run within 15K miles. Dealership diagnosed as cylinder misfire & repaired. Has occurred multiple times over life of ownership- always diagnoses as misfires. At apx 75K miles, upon cranking & during operation, heater became inconsistent in operation & this is still an issue. At apx 80K miles, upon cranking & during operation, ticking noise from front passenger side began. Faint at first & became increasingly louder within several days. Out of warranty. Solid check engine light began to appear off/on, remaining on for 24-48hrs then off 24-48hrs. Air conditioner conditioner has about a 15 sec delay before it turns on at every crank & power light for A/C slowly blinks until after the delayed start. Mechanic found 2 rocker heads damaged & they were replaced. Light not on at repair & code could not be pulled. Within 2 days of repair, a faint ticking noise became present on drivers side. Has been a week & ticking is now extremely loud. I am one of many with parallel issues & request this be addressed as my year & VIN do not fall in to the approved extended warranty to cover these very same issues.
