NHTSA Complaint #10607794 — 2012 JEEP GRAND CHEROKEE

ENGINE STARTED RUNNING ROUGHLY AND ATTEMPTED TO STALL IN TRAFFIC. CHECK ENGINE LIGHT CAME ON. I WENT TO JEEP DEALER IN GULF SHORES ALABAMA AND WAS TOLD THAT THE LEFT CYLINDER HEAD WAS DEFECTIVE. I WAS ALSO ADVISED THAT IT WAS A MANUFACTURING DEFECT THAT COULD RESULT IN CATASTROPHIC ENGINE FAILURE. IT IS A WELL KNOWN DEFECT IN THE 2012 CHEROKEES WITH THE 3.6 PENTASTAR ENGINE. IF THIS VEHICLE HAD STALLED WHILE ON AN INTERSTATE RAMP, OR A VALVE IN THE DEFECTIVE HEAD DROPPED DOWN INTO THE CYLINDER, AN ACCIDENT COULD RESULT. JEEP HAS FULL KNOWLEDGE OF THIS DEFECT BUT HAS NOT ISSUED A RECALL. THIS COULD BE AS SERIOUS AS THE GM IGNITION SWITCH ISSUE. *TR
