2016 Mazda CX-9

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.
