2010 MAZDA CX-9 Complaints

WHEN I AM AT A STOP AD START MY VEHICLE ACCELERATES WITHOUT MY ASSISTANCE, THIS HAPPENED ALSO WHILE BACKING UP AND MY FOOT WAS ON THE BRAKE. *TR

TL* THE CONTACT OWNS A 2010 MAZDA CX-9. THE CONTACT STATED THAT WHILE STARTING THE IGNITION, THE AIR BAG OFF WARNING INDICATOR REMAINED ILLUMINATED WHENEVER THERE WAS A FRONT SEAT OCCUPANT THAT WEIGHED LESS THAN ONE-HUNDRED POUNDS. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHERE THEY STATED THAT THE VEHICLE WAS OPERATING AS DESIGNED. THE TECHNICIAN ALSO STATED THAT THE AIR BAGS WOULD NOT DEPLOY WHENEVER THE AIR BAG INDICATOR ILLUMINATED. THE MANUFACTURER WAS NOTIFIED OF THE PROBLEM. THE APPROXIMATE FAILURE MILEAGE WAS 15,000. UPDATED 10/09/14*LJ THE CONSUMER STATED FURTHER TESTING SHOWS THE AIRBAG OFF LIGHT ILLUMINATED FOR PASSENGERS BETWEEN 115 POUNDS AND INTERMITTENTLY FOR PASSENGERS BETWEEN 115 AND 120 POUNDS. IT WAS SUGGESTED TO THE CONSUMER TO HAVE SMALL ADULTS RIDE IN THE BACK SEAT. UPDATED 8/10/2015 *JS

THE VEHICLE STALLS WHEN IDLING AT A STOP LIGHT OR IN A DRIVE THRU. THE VEHICLES MOTOR BEGINS TO SHAKE AND THEN EVENTUALLY DIES AND STALLS OUT AND THE VEHICLE MUST BE STARTED AGAIN WITH THE TURN OF THE IGNITION. THE BRAKING SYSTEM IS ALSO DEFECTIVE. WHEN AT A STOP LIGHT AND YOUR FOOT IS ON THE BRAKE PEDAL. THE PEDAL SUDDENLY SINKS AS IF THE BRAKE FLUID IN THE MASTER CYLINDER HAS DRAINED FULLY AND THE BRAKE PEDAL SINKS ALL THE WAY TO THE FLOOR AND THE VEHICLE SHOOTS FORWARD EVEN IF YOUR FOOT IS ON THE BRAKE. ANOTHER PROBLEM IS IN THE POWER DOOR LOCK SYSTEM. THERE HAS BEEN A TIME WHEN THE POWER DOOR LOCK WAS STUCK AND THE REAR RIGHT DOOR COULD NOT BE SHUT. I HAD TO DRIVE THE CAR TO THE DEALERSHIP WITH THE CAR DOOR FLOPPING ALL OVER THE PLACE. THEY WERE ABLE TO FIX IT AT THE DEALERSHIP BUT COULD NOT FIGURE OUT HOW IT OCCURRED. THEY WERE AS PUZZLED AS I WAS. THE CAR WAS BOUGHT BACK IN 2010 BRAND NEW FROM THE MAZDA DEALERSHIP. THE REVIEWS WERE GOOD FOR THE VEHICLE. ITS THE FIRST MAZDA WE PURCHASED AND IS PROBABLY GOING TO BE THE LAST. *TR

I WAS DRIVING AROUND A SHARP BEND IN THE ROAD. I PUSHED DOWN ON THE BRAKE PEDDLE TO SLOW DOWN AND THE CAR KEPT ACCELERATING AT THE SAME SPEED. THE CAR NEVER SLOWED DOWN AND I HAD TO TAKE THE CORNER AT A UNSAFE SPEED. I DROVE TO THE NEXT STREET AND TESTED THE BRAKES AND THEY WORKED FINE? VERY SCARY INCIDENT. *TR

TL* THE CONTACT OWNS ON A 2010 MAZDA CX9. THE CONTACT STATED THAT THE BRAKE PEDAL BECAME STUCK TO THE FLOORBOARD AND MADE A STRANGE NOISE WHILE ATTEMPTING TO STOP. THE CONTACT WAS ABLE TO RELEASE THE BRAKE PEDAL AND BROUGHT THE VEHICLE TO A STOP BY DEPRESSING THE BRAKE PEDAL SEVERAL TIMES. THE CONTACT WAS ABLE TO DRIVE THE VEHICLE TO AN INDEPENDENT MECHANIC FOR FURTHER INSPECTION. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE AND CURRENT MILEAGE WAS 51,000.

I NOTICED A HISSING SOUND WHEN PRESSING THE BRAKE PEDAL TODAY 3/20/2014 AND LOSS OF BRAKE PRESSURE. I NOTIFIED THE DEALER AND THEY PROMPTLY TOLD ME TO BRING IT IN RIGHT AWAY TO BE LOOKED AT. I DID HOWEVER A GOOGLE SEARCH FOR MAZDA CX9 BRAKE ISSUE AND NOTICE THERE ARE 7 OTHER INCIDENTS WITH CX-9 BRAKE ISSUE EXPLAINING THE SAME SYMPTOMS. "THE NHTSA COMPLAINTS SAY THAT THE PROBLEM CAUSES A HARD PEDAL, INCREASED BRAKING EFFORT AND REDUCED BRAKING EFFECTIVENESS. SOME COMPLAINTS ALLEGE THAT THEY HEAR A HISSING NOISE DURING BRAKING SIMILAR TO THE SOUND OF AIR LEAVING THE TIRES. NO INJURIES OR CRASHES HAVE BEEN REPORTED." I SHOWED THE DEALERSHIP THE GOOGLE SEARCH FROM THE INTERNET...PERTAINING TO 2010 CX-9 BRAKE ISSUES. MAZDA DEALER SOUNDS LIKE THEY ARE AWARE OF THE PROBLEM...AND SHOULD BE TAKING PROACTIVE CORRECTIVE MEASURES TO FIX THIS PROBLEM. *TR

THE CAR HAS BEEN TURNING OFF WHILE DRIVING WITH NO PRIOR INDICATIONS OR WARNINGS. ENGINE TURNS OFF AND STEERING WHEEL FREEZES AND LOCKS UP. THIS HAS OCCURRED MULTIPLE TIME AND WE HAVE TAKEN THE CAR TO THE DEALER A NUMBER OF TIMES WHO HAS INSPECTED IT AND EVEN KEPT IT AT THE SHOP DROVE IT FOR A NUMBER OF DAYS AND COULD NOT PINPOINT THE PROBLEM. WE HAVE MADE MAZDA USA AWARE OF THE ISSUE AND THE POTENTIAL THREAT OF THIS VEHICLE (THEY GAVE US A CASE # 149456450) HOWEVER, SADLY THEIR ATTITUDE IS THAT IF THE PROBLEM CANT BE PINNED THEN IT DOES NOT EXIST. THIS IS A CLEAR IGNORANCE ON MAZDA USA'S PART AND PUTTING THE PUBLIC IN A RISK WITH THIS VEHICLE. *TR

SEVERAL WEEKS AGO THE BRAKES STARTED MAKING A HISSING NOISE WHEN I WOULD DEPRESS THE BRAKE. THEN, THE CAR WOULD BRAKE AS USUAL UNTIL I NEEDED TO COME TO A COMPLETE STOP, WHEREAS THEN I WOULD NEED TO DEPRESS THE BRAKE VERY HARD TO MAKE THE CAR STOP, WHICH THEN IT WOULD STOP VERY SUDDENLY. THE MOST RECENT EVENT OCCURRED WHEN MY HUSBAND WAS DRIVING DOWN THE ROAD ABOUT 45 MPH AND HAD HIT THE BRAKES AND THE ENGINE COMPLETELY SHUT OFF, ALL THE WARNING LIGHTS CAME ON AND IT WAS VERY DIFFICULT FOR MY HUSBAND TO PULL THE CAR OVER AND COME TO A STOP. THE ENGINE DID START BACK UP AND WE DROVE ALL THE WAY HOME AND HAVE NOT SINCE DRIVEN THE VEHICLE. *TR

VEHICLE MAKES A HISSING SOUND (HEARD INSIDE THE VEHICLE) WHEN DEPRESSING THE BRAKE PEDAL. SOUNDS LIKE AN AIR LEAK. OCCASIONALLY THE PEDAL WILL GO HARD AS IF POWER ASSISTED BRAKING FEATURE IS LOST. VERY DANGEROUS SITUATION! VEHICLE TAKEN TO DEALER TODAY (02/24/14) AND WAS TOLD REPLACEMENT BRAKE BOOSTER IS REQUIRED. *TR

DRIVING IN SNOWY CONDITIONS; BRAKES FAILED TWICE WHEN I APPLIED LIGHT PRESSURE. FIRST TIME, THE BRAKES SHUDDERED, BUT THE CAR FINALLY STOPPED AFTER I APPLIED HARD PRESSURE; THE SECOND TIME IT HAPPENED, THE BRAKES SHUDDERED, AND NOTHING HAPPENED WHEN I FIRST APPLIED HARDER PRESSURE. EVENTUALLY THE CAR SKIDDED, BUT IT WAS TOO LATE. *TR
