NHTSA Complaint #11192600 — 2018 MAZDA CX-9

THIS VEHICLE IS HAS BEEN ON LEASE FOR 1 YEAR AND HAS LESS THAN 4000 MILES ON IT. INITIALLY WHILE ATTEMPTING TO START THE VEHICLE THAT HAD BEEN PARKED OVERNIGHT IT GAVE THE FOLLOWING WARNINGS: - KEYLESS ENTRY MALFUNCTION - CHARGING SYSTEM MALFUNCTION - VEHICLE OVERHEATING - BATTERY MALFUNCTION THE CAR WOULD NOT SHUT OFF UNTIL I HELD THE START/STOP BUTTON IN FOR ROUGHLY 20SECS. THE DEALER SERVICE CENTER TOOK THE CAR AND TOLD US THE BATTERY HAD A LOW CHARGE, CHARGED IT AND RETURNED IT. SEVERAL WEEKS LATER WHILE THE VEHICLE WAS IN MOTION WITH 2 ADULTS AND 2 CHILDREN ON A CITY STREET TRAVELING AT ABOUT 20MPH IT GAVE THE FOLLOWING WARNINGS: - KEYLESS ENTRY MALFUCTION - CHARGING SYSTEM MALFUCTION - VEHICLE OVERHEATING - BATTERY MALFUNCTION - PULL OVER TO SAFETY AT THIS POINT THE VEHICLE WAS STILL IN MOTION AND THE STEREO, HVAC, AND POWER STEERING CUT OUT. I WAS ABLE TO PULL THE VEHICLE OVER BUT AGAIN HAD TROUBLE SHUTTING IT OFF. I HAD TO HOLD THE START/STOP BUTTON FOR 20-40SECS. THE CAR WAS TOWED TO THE DEALER SERVICE CENTER. WE WERE TOLD BY THE SERVICE CENTER THAT A LOT OF 500 VEHICLES OF THIS YEAR AND MODEL HAD AN ENGINE HARNESS DEFECT THAT NO RECALL HAD BEEN ISSUED FOR BUT THEY WERE AWARE OF DEFECT AND HAD A FIX FOR IT. I FEEL I WAS LUCKY THAT I WAS ONLY TRAVELING 20MPH WHEN THE POWER STEERING CUT OUT. IF I HAD BEEN TRAVELING HIGHWAY SPEEDS ON A BEND THE SITUATION COULD HAVE BEEN TRAGIC AND I HAD MY CHILDREN IN THE CAR. CURRENTLY, BASED ON WHAT I'VE BEEN TOLD BY THE DEALER SERVICE AND SALES MANAGERS THERE ARE POTENTIALLY HUNDREDS OF OTHER 2018 CX-9S WHICH COULD EXPERIENCE THIS SAME MALFUNCTION WHILE IN MOTION.
