2016 Mazda CX-9 problems and owner complaints

ONE MILE FROM HOME THE SMART BRAKE SYSTEM MALFUNCTION & FRONT RADAR SYSTEM MALFUNCTION WAS DISPLAYED. CAR WAS SHAKING AND ACTING AS IF THE EMERGENCY BRAKE WAS ACTIVE WHILE THE CAR WAS IN MOTION. CAR WAS SLOW TO ACCELERATE. HAD I BEEN ON THE INTERSTATE I COULD HAVE BEEN REAR-ENDED. PULLED OVER TO TURN THE CAR OFF AND BACK ON. CAR WAS OKAY THE REMAINDER OF MY 20 MILE DRIVE.

IMMEDIATELY UPON MAKING A SHARP RIGHT TURN INTO A PARKING SPOT, THE CAR SUDDENLY ACCELERATED AT A VERY FAST PACE WITHOUT ME PUSHING THE GAS PEDAL. MY IMMEDIATE REACTION WAS TO PRESS ON THE BRAKE, BUT IT DID NOT STOP. THE CAR SLAMMED INTO A PLANTER IN FRONT OF ME. THE CAR MOVED SO QUICKLY THAT IT WAS LODGED INTO THE BUSHES AND HAD TO BE PULLED OUT BY A TOW TRUCK. I IMMEDIATELY CALLED THE DEALER SERVICE DEPARTMENT AND TOLD THEM WHAT HAPPENED. THE SERVICE MANAGER'S IMMEDIATE REACTION WAS TO SCOFF AT THE IDEA THAT THE CAR ACCELERATED ON IT'S OWN.…

At an intersection the engine stalled and car was extremely hard to restart (took several minutes). I later noticed oil and coolant dripping from the engine and coolant mist/vapor from the exhaust. Later I learned it was possibly related to Mazda's own TSB Bulletin No: 01-013/21 where a manufacturing defect caused coolant to enter the combustion chamber and hydro lock the engine (where I stalled and had hard time restarting). I had to have the car towed home. At home I noticed the passenger underside of the vehicle coated with oily/watery resi…

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 JUS…

MY WIFE AND DAUGHTERS TOOK A TRIP, AND ON THE WAY HOME, THE ENGINE LIGHT CAME ON. WHEN TURNING ON THE ENGINE TO CHECK THE ENGINE LIGHT, I NOTICED THAT THE BRAKE PEDAL WAS HARD. I WAS THINKING THE ENGINE LIGHT HAD TO DO WITH THE GAS CAP NOT BEING ON TIGHT SINCE FAMILY PURCHASED GAS ON THE TRIP BACK HOME. I DROVE THE CX-9 TO AUTOZONE TO DETERMINE THE CODE FOR THE ENGINE LIGHT. THE ATTENDANT AT AUTOZONE WAS UNABLE TO REGISTER A CODE. HOWEVER, I NOTICED THE BRAKES FELT DIFFERENT ON THE DRIVE TO AUTOZONE. ALTHOUGH I HAD TO APPLY MORE PRESSURE TO STO…

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The entire electrical system is malfunctioning. All dashboard service lights (check engine, ABS, etc.) illuminate simultaneously, causing the vehicle to stutter and shut off while driving. The vehicle is available for inspection. 2. How was your safety or the safety of others put at risk? This issue has resulted in a dangerous situation, particularly when the vehicle lost power on the highway with my young children aboard. This sudden loss of …

THE PUSH BUTTON ON/OFF SWITCH DOES NOT PROTECT AGAINST TURNING THE VEHICLE OFF IF TRANSMISSION IS ACCIDENTALLY LEFT IN ANY POSITION OTHER THAN 'P'. FOR EXAMPLE ITS POSSIBLE TO PUT THE TRANSMISSION IN 'R' AND TURN THE VEHICLE OFF. FOR A BUSY PARENT (TARGET DEMOGRAPHIC OF THIS VEHICLE), THIS IS VERY DANGEROUS. IF ON AN INCLINE, THE VEHICLE WILL START ROLLING FORWARD OR BACKWARD (DEPENDING ON INCLINE/SLOPE AND R/D TRANSMISSION POSITION). THERE SHOULD BE A SAFEGUARD OR A BEEP/WARN SYSTEM TO PROTECT THE DRIVER/OCCUPANTS THIS HAPPENED TO ME ON AN …
