NHTSA Complaint #11208319 — 2010 MAZDA CX-9

THE ENGINE OVERHEATED WHILE DRIVING ON A HIGHWAY AT HIGH SPEED AND FAILED WITHOUT WARNING. AFTER INVESTIGATION IT WAS FOUND THAT WATER PUMP MALFUNCTIONED FORCING COOLANT INTO THE ENGINE. IT IS NOW COMPLETELY INOPERABLE AND THE CAR HAS ONLY AROUND 80,000 MILES ON IT. THIS IS A MAJOR SAFETY ISSUE! THE CAR WAS SERVICED AND OIL CHANGED JUST A FEW MONTHS BEFORE THIS HAPPENED. THIS IS A MAJOR DESIGN FLAW ON MAZDA'S PART, WHICH THEY SEEM TO KNOW ABOUT AND NEVER ISSUED A RECALL TO GET ALL THE CARS FIXED. REPLACING AN ENGINE IS NOT SOMETHING MOST FAMILIES HAVE THE BUDGET FOR OR EVEN THINK ABOUT WHEN THE CAR IS LESS THAN 10 YEARS OLD. THERE WERE NO WARNING SIGNS OF WATER PUMP FAILURE. MAZDA NEEDS TO WARN CX-9 OWNERS WITH TSB OR RECALL THE WATER PUMP. THE WATER PUMP IS NOT BURIED INSIDE THE ENGINE AND CANNOT BE VISUALLY INSPECTED. HAVING A VEHICLE SHUT OFF ABRUPTLY WHEN TRAVELING AT HIGH SPEEDS IS A SERIOUS RISK FOR BOTH DRIVER, VEHICLE OCCUPANTS AND SURROUNDING MOTORISTS. I HOPE NHTSA TAKES THIS COMPLAINT SERIOUSLY AND TAKES ACTION BEFORE A SERIOUS OR FATAL INJURY OCCURS.
