Brakes stopped working while we were on vacation. Made the drive down fine, but the next day went to drive the car, pressed the brakes and the car did not come to a complete stop. Also made a funny noise when we tried to press on the brakes. My husband practically had to stand up and push all the way down to get car to stop. Luckily we were not in a congested or confined place. Ended up replacing the brake booster. Three weeks later my acceleration stopped working intermittently. I go to press the gas and the car doesn’t go. The dealership is saying it’s the brake signal.

Breaks became very hard to press and I was having trouble stopping the car. I could not drive it to the Mazda dealer who was too far. I took a chance and drove a few miles to local break shop. They replaced the master cylinder and the break booster. Parts and labor were $1083.87

When I press on my brakes, I hear air. I am fortunate that, as of this reporting, I have not had an accident. My brakes do not fully stop my car, so I have to judge when to brake in order to slow down and not hit the car ahead of me. Very scary when your car won't stop! I have read other complaints on the Mazda CX9s built in 2013 having an issue with the brake booster. PLEASE recall these 2014 Mazdas so the appropriate repairs can be made. Working brakes are ESSENTIAL!

The dealer indicated that I had to replace the brake booster. This is a 2014 CX-9. A NHTSA search showed that vehicles manufactured in 2013 were affected. My car was purchased in Feb 2014. I suspect this one too had that faulty equipment.

OUR 2014 MAZDA CX-9 POWER BRAKE BOOSTER HAS GOTTEN PROGRESSIVELY WORSE OVER THE LAST FEW MONTHS AND HAS NOW FAILED AT 75,269 MILES WHERE THE PEDAL IS SPONGY, PEDAL TRAVEL IS LONG AND THERE IS A HISSING NOISE (AIR LEAKAGE) FROM THE POWER BOOSTER, ALL RESULTING IN SEVERELY REDUCED BRAKE EFFECTIVENESS - VERY LITTLE. WE CANNOT SAFELY DRIVE THE CAR. THIS IS THE SAME FAILURE AND SAFETY DEFECT THAT WAS THE SUBJECT OF ODI INVESTIGATION PE-14-005 (ODI CLOSED 2/10/2014) INVOLVING 2007-2013 MAZDA CX-9 VEHICLES IN WHICH THE ODI RESUME SAID "THE AGENCY WILL CONTINUE TO MONITOR COMPLAINTS AND OTHER INFORMATION RELATING TO THE ALLEGED DEFECT AND TAKE FURTHER ACTION IN THE FUTURE IF WARRANTED." IN THAT CASE, IN ORDER TO AVOID A RECALL, IN MARCH 2014 MAZDA AGREED WITH THE NHTSA/ODI TO EXTEND THE WARRANTY FOR 7 YEARS OR 100,000 FOR THE 2007-2013 MAZDA CX-9 VEHICLES AND REPAIR THE CONDITION AND INITIATED SPECIAL SERVICE PROGRAM SSP93. THIS NOW IS EXACTLY THAT SAME CONDITION BUT IN THE NEXT YEAR MODEL - A MODEL 2014 MAZDA CX-9 MANUFACTURED IN 2013 THAT OBVIOUSLY RECEIVED THE DEFECTIVE POWER BRAKE BOOSTER THAT WAS MANUFACTURED BEFORE THE BOOSTER SUPPLIER CORRECTED THE FAULTY BOOSTER MOLD IN FEBRUARY 2013. YESTERDAY (4-29-21) MAZDA SAID (MAZDA CUSTOMER SERVICE REFERENCE # 1-378914617) OUR VEHICLE IS NOT COVERED FOR THE REPAIR BECAUSE THE NHTSA/ODI AGREEMENT AND SSP93 ONLY APPLIES TO 2007-2013 VEHICLES WHERE OURS IS A 2014, EVEN THOUGH IT WAS MANUFACTURED IN 2013. THIS IS NOT ONLY ANOTHER EXAMPLE OF THE SAME PROBLEM NOW EXISTING IN 2014 MAZDA CX-9'S WITH A POWER BOOSTER MANUFACTURED BEFORE THE FEBRUARY 2013 FAULTY BOOSTER MOLD CORRECTION, IT IS UNCONSCIONABLE FOR MAZDA TO REFUSE THE REPAIR. PLEASE - WE NEED YOUR HELP IN RESOLVING THIS - AND NEED YOU TO RE-OPEN THE INVESTIGATION FOR THE SAFETY OF OTHERS. THANK YOU.

PE15022 · Lower Ball Joint Separation

Opened Jun 9, 2015 · Closed Aug 20, 2015

Status: closed (inferred from source dates) · Suspension:front:control Arm:lower Ball Joint

In an July 7,2015 letter to NHTSA, Mazda identified a safety defect that could result in lower ball joint separation in approximately 193,484 model year (MY) 2007 through 2014 Mazda CX-9 vehicles (NHTSA Recall No. 15V-451,Mazda 8515G).Mazda indicated that damage to the ball joint boot may allow water to enter the front suspension ball joint fitting during use which may result in premature ball joint wear and a progressively looser joint.In January 2014, Mazda implemented redesigned lower control arms in production vehicles to improve the durability of the lower ball joints.The redesign involved changing the shape of the top surface of the ball joint boot cover and adding a suspension plate to the undersurface of the knuckle.Mazda's recall will replace the defect lower control arms with the redesigned parts.ODI's analysis of information collected during PE15-022 identified a total of 62 ball joint separation incidents, including 34 identified in ODI complaints and 31 identified in Mazda complaints and field reports (3 of the Mazda records involve vehicles/incidents that were also reported to ODI).When Mazda's design change was implemented, most of the field experience related to lower ball joints involved complaints of noise and premature wear-out.Only 1 of the ODI and 6 of the additional Mazda separation complaints identified in ODI's analysis were reported prior to January 2014.Significant increases in the number and trend in separation complaints were observed in 2015, when 30 of the ODI complaints and 16 of the additional Mazda complaints were reported.The report trend appears to be accelerating, with 29 of the reports received after ODI opened PE15-022 on June 9, 2015.There has been one crash reported to ODI related to the alleged defect (VOQ 10746510). This investigation is closed based on Mazda's recall.The 34 VOQs associated with this investigation are: 10747358, 10746510, 10744897, 10743509, 10736229, 10735938, 10734763, 10734302, 10734290, 10733813, 10732578, 10732217, 10732154, 10731850, 10730736, 10730280, 10730143, 10730114, 10726622, 10726480 10726448, 10726168, 10725839, 10725567, 10725488, 10725427, 10725390, 10717510, 10714469, 10695142, 10668978, 10648429, 10640541, 10546535
