SAFETY ISSUE: VEHICLE COULD NOT BE SAFELY DRIVEN. THE POWER LIFT GATE GOT STUCK FULLY OPEN AND WOULD NOT MOVE UP OR DOWN. IT COULD NOT BE SHUT MANUALLY. THE ROD HOLDING THE DOOR WHICH IS PULLED DOWN INTO THE MOTOR WOULD NOT BUDGE. THE VEHICLE COULD NOT BE SAFELY DRIVEN WITH THE HATCH STUCK OPEN LIKE THAT. I HAD TO FIND A WAY TO DISENGAGE THE ROD FROM THE LIFE GATE. STILL, EVEN WITH THE ROD DISENGAGED, IT COULD NOT BE FULLY SHUT. I WAS ABLE TO TIE DOWN THE HATCH HALF WAY SHUT SO THAT I COULD DRIVE IT TO A DEALERSHIP TO BE REPAIRED. BY RESEARCHING SIMILAR PROBLEMS OTHER CX-9 OWNERS HAD, I WAS ABLE TO DETERMINE THAT INSULATION AROUND THE WORM GEAR OF THE MOTOR, BEHIND THE LEFT REAR PANEL, HAD LOOSENED AND GOTTEN CAUGHT IN THE WORM GEAR. THIS IS A PROBLEM THAT IS RELATED TO CONSTRUCTION OF THE VEHICLE, SINCE THE INSULATION IS BEHIND A SECURED PANEL AND NOT ACCESSIBLE BY THE OPERATOR. *TR

SERVICE BRAKES
OUR 2012 MAZDA CX9 SPORT FWD LOST ALL BRAKE BOOST ON SEVERAL OCCASIONS. MY WIFE COMPLAINED THE VEHICLE WOULD NOT STOP WHEN BACKING. I DROVE THE VEHICLE AND I WAS ONLY ABLE TO STOP THE VEHICLE AFTER SIGNIFICANTLY INCREASING PRESSURE ON THE BRAKE PEDAL. THE MAZDA DEALER ADVISED IT WAS INDEED THE BRAKE BOOSTER. THIS IS A SERIOUS SAFETY ISSUE AND NEEDS TO BE ADDRESSED BY MAZDA AND NHTSA. OUR VEHICLE WAS LESS THAN A YEAR OLD WITH LESS THAN 10000 MILES AT THE POINT OF FAILURE. *TR
