NHTSA Complaint #11181363 — 2013 JEEP WRANGLER

WITH NO LEAKS AND LESS THAN 65,000 MILES, THE AMOUNT OF HEAT PRODUCED THROUGH THE VEHICLES HEATING SYSTEM HAS BEEN STEADILY DIMINISHING TO THE POINT THAT IT NOW ONLY BLOWS COOL AIR. THIS CONDITION IS PRESENT EVEN AFTER THE VEHICLE IS UP TO OPERATING TEMPERATURE AND HAS BEEN IN CONTINUOUS OPERATION. RESEARCH HAS INDICATED THAT A ENGINE COMPONENT MANUFACTURING DEFECT (CASTING SAND RESIDUE) HAS DIRECTLY CAUSED THIS CONDITION WITH THE SAND RESIDUE ACCUMULATING IN THE HEATER CORE AND RESTRICTING/BLOCKING THE FLOW OF COOLANT THROUGH THE HEATER CORE.
