Open the full vehicle complaint log (all categories)MY MAZDA CX-9 RAN OUT OF GAS ON A MAJOR HIGHWAY (ROUTE 90 IN BOSTON) AND THE GAS GAUGE READ HALF FULL. NO 'OUT OF GAS' LIGHT WENT ON AND RANGE (UNDER INFORMATION) SAID 191 MILES REMAINING. MY MAZDA DEALER TOLD ME THE SOFTWARE NEEDED TO BE RESET (NOT DONE YET AS OF THIS WRITING). IT IS A MAJOR ISSUE IF THE GAS GAUGE IS NOT READING PROPERLY AND THIS IS A SOFTWARE ISSUE (A BUG?). MAZDA NEEDS TO FIX THIS FOR ALL MAZDA'S AND ISSUE A RECALL SO IT DOES NOT HAPPEN AGAIN.
WHILE DRIVING THE CAR IN THE 287 INTERSTATE HIGHWAY IN NEW JERSEY, I GOT THE CHECK ENGINE LIGHT OUT OF THE BLUE AND THE CAR STARTED DECELERATING IN THE HIGH SPEED LANE. LUCKILY I WAS ABLE TO MANAGE AND GET THE CAR TO THE ROAD SIDE SHOULDER. I WAS NOT ABLE TO START THE CAR AFTER THIS INCIDENT. WE HAD TO TOW THE CAR TO THE MAZDA SERVICE CENTER IN GREENBROOK, NEW JERSEY. AFTER RUNNING THE CAR DIAGNOSTICS (ERROR CODE - P0192), THEY INFORMED ME THAT THEY HAD TO UPDATE THE PCM (POWER CONTROL MODULE) SOFTWARE. THATS THE ONLY EXPLANATION WHICH THEY GAVE WHICH MADE NO REAL SENSE. THEY DID NOT PROVIDE ANY INFORMATION WHY THIS ISSUE OCCURRED AND WHAT WAS DONE TO MAKE SURE THIS ISSUE DOES NOT OCCUR IN THE FUTURE.
IN 2017, MY CAR SHUT OFF TWO TIMES, WITHOUT WARNING, ONE TIME AT A STOP LIGHT AND AGAIN ON THE HIGHWAY GOING 70MPH. WE WERE ACCELERATING AT THE STOP LIGHT WHEN IT SHUT OFF AND THEN DRIVING ON THE HIGHWAY. TOOK THE CAR TO THE DEALERSHIP AND 72 CODES CAME UP. THEY SAID IT WAS THE DVD PLAYERS (THAT THEY SOLD AND INSTALLED!!!) THAT WERE CAUSING THE ISSUE. THEY SUPPOSEDLY 'FIXED' THE ISSUE. NOW IN JULY 2019, THE CAR SHUT OFF AN ADDITIONAL FIVE TIMES. THREE TIMES WHILE DRIVING AND TWICE IN A PARKING LOT. WE WERE ON A HIGHWAY AGAIN WHEN THE CAR JUST SHUT OFF WITH NO WARNING, LIGHTS ON THE DASH STARTED FLASHING, AND THE POWER STEERING WENT OUT ONE OF THE TIMES. MY HUSBAND HAD TO PUT IT IN NEUTRAL, COAST TO THE SHOULDER, COME TO A COMPLETE STOP AND THEN ATTEMPT TO START IT EACH TIME. CARS WERE DODGING US EVERY TIME AND LUCKILY WE WEREN'T HURT. MY CHILDREN WERE IN THE VEHICLE EVERY SINGLE TIME. WE HAD THE CAR TOWED TO THE DEALERSHIP WHERE 68 CODES CAME UP. THIS TIME THEY'RE SAYING IT'S THE FUEL PUMP AND THAT THEY CAN 'FIX' IT, BUT CAN'T 100% GUARANTEE IT WON'T HAPPEN AGAIN. WE WERE PUT IN A LIFE THREATENING SITUATION EVERY TIME, WITHOUT WARNING, AFTER GIVING THE DEALERSHIP A CHANCE TO FIX IT. THE CAR IS UNDER THREE YEARS OLD AND ONLY HAS 30,400 MILES ON IT.
I BOUGHT THE CAR SATURDAY. FOUR DAYS LATER, I FILLED THE TANK AT 2:00 PM FOR THE FIRST TIME. I THEN DROVE ABOUT 30 MILES. WHEN I ARRIVED HOME AT 5:00PM, I PARKED IN THE GARAGE. I NOTICED THE ODOR OF FUEL AS SOON AS I EXITED THE CAR AND CHECKED TO MAKE SURE I HAD SECURED THE GAS CAP, WHICH I HAD. THIRTY MINUTES LATER, THE ENTIRE DOWNSTAIRS OF OUR HOUSE SMELLED LIKE GASOLINE. THE GARAGE WAS CONSUMED WITH FUEL ODOR, AND THE FIRE POTENTIAL CAUSED US TO RETURN THE CAR TO THE DEALERSHIP IMMEDIATELY AFTER THAT. THE FUEL ODOR WAS PRESENT WITHIN THE CAR AS WELL.
