The dealer was made aware of the failure and confirmed that the vehicle had been repaired under NHTSA Campaign Number: 15V451000 (Suspension). The dealer referred the contact to the manufacturer for assistance. An independent mechanic replaced the passenger's side lower control arm; however, the contact stated that after the repair was performed, the engine rattled and the vehicle stalled. The vehicle was then taken back to the independent mechanic, who determined that the driver's side lower control arm spacers were missing and that the front and rear axles, brakes, and rear shocks needed to be replaced. Additionally, the cage bolts needed to be retightened. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was opened.

I was driving along the highway and traffic began to slow. I pushed the brakes and the car did not stop.

Brake booster failure caused a near miss. Wife driving with 5 year old daughter in the vehicle. The stopping force required on the brake pedal became excessive and the stopping (safe braking) distance significantly increased causing emotional distress. My understanding is this part (brake booster) has a defective diaphragm that deteriorates over time. The extended warranty created for this particular issue did not cover the vehicle at the time of the failure.

I WAS TURNING RIGHT INTO A PARKING SPACE WITH MY FOOT ON THE BRAKE, WHEN THE CAR SUDDENLY ACCELERATED. THE ENGINE REVVED UP AND THE CAR DARTED FORWARD. FOR A SPLIT SECOND I LIFTED MY FOOT TO MAKE SURE I WAS NOT PRESSING ON THE ACCELERATOR, AND IMMEDIATELY PUSHED BACK DOWN ON THE BRAKE AS HARD AS I COULD; THE CAR CONTINUED TO SPEED FORWARD. INSTINCTIVELY I KEPT THE WHEEL TURNED TO THE RIGHT TO AVOID CRASHING INTO THE BUILDING IN FRONT OF ME AS THE CAR JUMPED THE CURB, BUT I HIT 2 PARKED CARS. ONCE I WAS ALMOST STOPPED BY HITTING THE 2 PARKED CARS, I QUICKLY TURNED THE KEY OFF AND PUT THE CAR IN PARK. I HAVE NEVER EXPERIENCED THIS ISSUE BEFORE; AND LET ME TELL YOU, I WAS TERRIFIED. I HAVE PICTURES THAT SHOW TIRE MARKS EITHER FROM THE CARS ACCELERATION OR DRAGGING THE BACK WHEELS FROM PUSHING ON THE BRAKE.

THE BRAKING SYSTEM DID NOT FUNCTION CORRECTLY RESULTING IN A CRASH. BRAKES WERE HARD AND COULD NOT BE DEPRESSED WHEN A VEHICLE STOPPED QUICKLY IN FRONT OF ME. TOOK THE CAR TO MAZDA DEALERSHIP AND THEY INFORMED ME THAT THIS IS A KNOWN PROBLEM AND REPLACED THE BRAKE BOOSTER UNDER A "SPECIAL WARRANTY". THIS NEEDS TO BE A SAFETY RECALL, I WAS NEVER NOTIFIED OF THIS SAFETY ISSUE. IT IS IMPERATIVE THAT NHTSB REOPEN THE INVESTIGATION ON THIS PROBLEM AS IT DOES NOT ONLY INVOLVE 2010 AND 2011 CARS AND DOES NOT ONLY OCCUR IN "HIGH AMBIENT TEMPERATURES". VEHICLE WAS IN MOTION AND WAS SLOWING ON AN SLIGHT UPHILL GRADE. VEHICLE IS 5 YEARS OLD AND HAS 53,000 MILES.
