NHTSA Complaint #11329177 — 2013 JEEP WRANGLER

MY 2013 JEEP WRANGLER STARTED HAVING A CODE THAT READ "MISFIRE ON CYLINDER 6" AT ABOUT 55,000 MILES. AFTER CHANGING THE SPARK PLUGS AND IGNITION COILS ON THE DRIVERS SIDE BANK OF CYLINDERS (2,4,AND 6) THE TROUBLE CODE STILL CONTINUED TO POP UP ABOUT EVERY WEEK OR TWO. I THEN TOOK IT TO MY LOCAL JEEP, CHRYSLER, RAM DEALER TO INVESTIGATE FURTHER. AFTER DOING SOME RESEARCH I FOUND OUT THAT THE CYLINDER HEADS ON THE PENTASTAR ENGINE IN THE 2012 AND 2013 JEEP WRANGLERS WERE HAVE MANY, MANY ISSUES WITH THE BAD CYLINDER HEADS BECAUSE OF THERE WAS TWO DIFFERENT METALS USED BETWEEN THE ENGINE BLOCK AND THE CYLINDER HEAD CAUSING IT TO WARP AND CAUSE COMPRESSION ISSUES IN THE CYLINDER. JEEP WAS WELL AWARE OF THIS PROBLEM BUT REFUSED TO THIS DAY TO ISSUE A RECALL. AFTER THE DEALER TOOK THE ENGINE APART TO INVESTIGATE, HE ADMITTED TO THE FACT THAT IT WAS A BAD CYLINDER HEAD. THIS MISFIRE ON CYLINDER 6 OCCURRED MOSTLY WHEN IDLING AT A TRAFFIC LIGHT OR AT VERY LOW SPEEDS. THE KICKER IN ALL OF THIS EVEN THOUGH JEEP ADMITTED A FAULTY CYLINDER HEAD WAS THE CAUSE OF THE LOSS OF COMPRESSION, THEY REFUSED TO REPLACE THE CYLINDER HEAD AT THEIR COST. BECAUSE JEEP DID NOT HAVE MY VIN NUMBER IN THEIR LIST TO BE REPAIRED, IT WAS UP TO ME TO PICK UP THE COST. I DID NOTHING IN THE TIME THAT I HAVE HAD THIS VEHICLE (ORIGINAL OWNER) TO MAKE A CYLINDER HEAD BECOME WARPED. THIS WAS A PROBLEM WITH THE PENTASTAR ENGINE FROM THE BEGINNING. TOO BAD JEEP DOESN'T DO THE RIGHT THING AND REPAIR THESE PENTASTAR ENGINE ISSUES AT THEIR EXPENSE RATHER THAN HEAPING MORE RESPONSIBILITY ON THE CONSUMER. *TR
