2015 Jeep Wrangler Engine

Faulty oil cooler. 2 different mechanics reported this as a common problem with 2015 jeep wrangler. Due to the way this model was made, the oil cooler is too close to the hot engine making it faulty. As well as the parts around it all have to be replaced. I've been told not to drive the vehicle due to fire hazard. The estimates I've been given are $1400 and up. I've also read many complaints about this same issue, same vehicle, same year, on several different web sites.

I’ve heard many complaints that the oil filter housing on the 2014 jeeps and up have had cracking problems

The contact owns a 2015 Jeep Wrangler. The contact stated that while driving at various speeds, the vehicle lost motive power and stalled. The contact stated that the failure had occurred several times while driving on a busy freeway. The failure also occurred while the vehicle was idling at a red light. After the failure, the vehicle was restarted and operated normally. The vehicle was taken to the local dealer who was unable duplicate a failure or determine the cause of the failure. The vehicle was not repaired. The contacted stated that after retrieving the vehicle the failure persisted. The manufacturer was also notified of the failure. The failure mileage was 113,000.

My Jeep has a left cylinder head failure at 78k miles. Jeep forums are full of discussions regarding this issue. The dealer says there is no reason for the failure and that they have seen this before. Jeep says my warranty is expired so I am out of luck. This is my third Jeep and the first time I have had any issue mechanically. This failure is not from normal wear and tear. It's very frustrating that no recall on this obviously faulty engine part exists.

I OWN TWO JEEP WRANGLERS, A 2013 AND A 2015. I HAD THE 2015 REPAIRED AT A COST OF OVER $1,000.00. NOW MY 2013 HAS DEVELOPED THE SAME PROBLEM; TO WIT, THE OIL COOLER/ OIL FILTER HOUSING CRACKS ON CHRYSLER 3.6 ENGINES AND THE OIL IS SPREAD ONTO THE EXHAUST PIPE WHICH HAS THE POTENTIAL OF CAUSING A FIRE. IF THIS IS NOT DISCOVERED, THE OIL WILL SPREAD TO THE REAR TIRES WHICH WILL CAUSE A TRACTION OR BRAKING HAZARD. CHRYSLER HAS NOT MODIFIED THE HOUSING AND WHEN YOU REPLACE , IT IS REPLACED WITH THE SAME PART THAT WILL FAIL IN THE FUTURE. CHRYSLER HAS TO KNOW THAT THIS PROBLEM EXISTS BY THE # OF UNITS THAT THEY HAVE SOLD, NOT TO MENTION THE THOUSANDS OF UNITS THAT ARE SOLD ON EBAY AND AUTOMOTIVE PARTS STORES. THERE SHOULD BE A RECALL ON THIS SITUATION BEFORE PEOPLE ARE INJURED OR KILLED.

Oil filter housing leaking oil,build up of oil sludge on top of intake manifold,if build up persists it may cause vehicle to catch fire

There’s a ticking sound coming from my engine and it’s misfiring in cylinder 5 and the check engine light is on. My concern is it’s the rocker arm

I have had the oil filter housing crack two times costing over 1 grand each time to have replaced by a shop. The lifters and rockers have gone out on each side of engine now with not even 91k miles on vehicle. Drivers side had 62,000 miles and then the passenger side had 91,000 miles on it. Maintenance has been done on time and not over due.

Our temperature gauge says it’s overheating but it’s not overheating. We’ve had the radiator replaced twice. We’ve had it at three different places to take a look at it, we had the dealership look at it and says they can’t find anything. But it keeps losing coolant. This has been going on for the last 6 to 9 months can’t drive the car more than a few miles.

Check engine light came on. Took jeep to dealership - indicated that the left side cylinder head needed replaced, not placing would cause extensive damage. The vehicle had 65779 miles on it and is in excellent condition, there was no reason for the engine to have such significant problems based on usage. Learned this is a faulty issue and that Jeep is aware of it, although no additional warranty or recall was provided. I was paid over $3,392 to get the issue diagnosed and repaired.

No crash or injuries. My Jeep only has 45,000 original miles and it is leaking oil from the oil cooler. I researched and this seems to be a very common issue with the 2015 3.6 L Jeep Wrangler. It cost over $1,500 to repair. As the other gentleman stated in his complaint, I feel this is a major issue that needs to be addressed by Jeep. See the other post below for further detail: I OWN TWO JEEP WRANGLERS, A 2013 AND A 2015. I HAD THE 2015 REPAIRED AT A COST OF OVER $1,000.00.

I have owned my Jeep since 2015 and bought it brand new from the dealership. I have replaced the thermostat three times already. Yesterday, 1-21-22, I was driving home on the interstate. The thermostat stuck again, would not open, and caused it to start dumping coolant out of it while driving. That caused the belt to slip and causing me to almost get into an accident trying to pull over. This Jeep has had several issues with overheating in the almost seven years I’ve had it.

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.

I have 2015 Jeep Wrangler Unlimited Rubicon 1000,15 miles on and it has the ticking noise. I took it to my independent mechanic shop. The independent mechanic diagnosed the issue and said that the tick is coming from the passenger side of the Engine .I chatted with FCA to see if they can provide any assistance on this issue they denied even if the vehicle its out of warranty therefore is has to be cover out of my pocket cost.

My 2015 Jeep Wrangler with 80,200 developed the well know Pentastar Tick. The Jeep would misfire at idle when slowing to a stop light. The check engine light came on and the code was a P0304. I'm the original owner and took it to the dealer I purchased it from. They diagnosed the issue and called me stating that he Jeep needs new rockers and a cam shaft on the drivers side engine bank. FCA has known about this issue since 2012. I called FCA to see if they would provide any assistance to repair the Jeep. FCA refused to acknowledge that this issue exists and refuses any assistance for owners even slightly out of warranty even though it is a manufacturing defect.

2015 Jeep Wrangler 66,000 mi on it rocker arms are rattling need to be replaced it's a problem at all 2015 what I understand

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.

TL* THE CONTACT OWNS A 2015 JEEP WRANGLE. 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.

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 WRANGLERS. 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 WRANGLERS. 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

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.
