2011 MAZDA CX-9 Complaints

I HAD MY CX-9 GT DRIVING ON THE ROAD. THIS HAPPENED WHILE I DROVE ON STREET AND STEPPED ON BRAKE THE PEDAL TO STOP FOR A RED LIGHT. I ALMOST HIT THE CAR IN FRONT OF ME, BECAUSE MY BRAKE AT THIS TIME, ALL OF SUDDEN, TOOK LONGER STOPPING DISTANCE AS I EXPECTED. IT WAS A CLOSE CALL TO HIT THE CAR IN FRONT OF ME WHILE MY BRAKING SYSTEM REACTED DIFFERENTLY. AFTER ALMOST HITTING THE CAR, I DROVE VERY CAUTIOUSLY IN A FEAR THAT I MIGHT LOSE THE CONTROL OF MY BRAKES TOTALLY; THE BAD FEELING FOR THE UNPREDICTABLE BRAKING SYSTEM REALLY PUT MY FAMILY'S SAFETY IN A COMPROMISE. I HAVE ONLY HAD THIS CAR FOR ONE AND HALF YEAR AND DROVE AROUND 24,000 MILES. THIS NEVER HAPPENED TO THE THREE CARS I HAVE DROVE IN MY 20 YEARS OF DRIVING HISTORY. THE BRAKING SYSTEM SHOULD BE DESIGNED AND PROVIDE WHAT IT SHOULD PERFORM WITHOUT ANY COMPROMISE. BUT THIS ONE DIDN'T DO THE JOB IT SHOULD. DON'T EVEN SEE ANY WARNING LIGHT IN THE DASH. TODAY, I TOOK MY CAR TO THE MAZDA SERVICE. THEY RESPONDED THAT ONE OF THE COMPONENTS OF THE BRAKING SYSTEM IS DEFECTIVE. THEY MENTIONED THAT THE "BRAKE BOOSTER" IS BROKEN. I AM SO SURPRISED AT HOW THESE INSTRUMENTAL SYSTEMS EASILY BREAK IN JUST LESS THAN TWO YEARS, WITHOUT ANY WARNING?? WOULD THIS BE A SERIOUS ISSUE THAT WOULD AFFECT ANY CX-9 MODELS AND CAUSE FURTHER LIFE THREATENING RESULTS. I LIKE TO POP UP THIS CONCERN TO THE SAFETY AUTHORITY FOR FURTHER INVESTIGATIONS.

THE TRACTION CONTROL LIGHT ON MY CX9 COMES ON AND STAYS ON, EVEN IN DRY CONDITIONS IN WHICH THE TRACTION CONTROL SYSTEM IS NOT NEEDED. ALSO THE TCS SYSTEM LIGHT IS ILLUMINATED AND THE TCS OFF LIGHT IS ILLUMINATED. *TR
