WHEN DRIVING VEHICLE A SEVERE SHUDDERING VIBRATION AND LOUD NOISE EMANATED FROM FRONT END OF VEHICLE, AS IF FRONT AXEL WAS GOING TO FALL OFF. HAPPENED THREE TIMES SO FAR. ONCE TO MY WIFE, ONCE TO ME, AND ONCE TO THE MECHANIC. VERY FRIGHTENING EACH TIME, CAUSING DRIVERS TO PULL OVER AND TURN OFF VEHICLE. THEN VEHICLE DRIVES OK FOR A WHILE. HAPPENED WHILE DRIVING STRAIGHT FORWARD. MECHANIC STATES IT IS A FAILED POWER TRANSFER UNIT. MECHANIC'S RESEARCH INDICATED IT IS A BIG PROBLEM IN MAZDA CX-9 VEHICLES, AND A CLASS ACTION LAWSUIT WAS FILED AND RESULTED IN A SETTLEMENT. AS FAR AS I CAN TELL THAT SETTLEMENT DOES NOT COVER MY VEHICLE YEAR (2008), AND IS LIMITED TO VEHICLES MANUFACTURED AFTER 2010, AND WHICH MEET CERTAIN SPECIFICATIONS. MECHANIC ESTIMATES REPAIR WILL RUN IN THE $1100-$1500 RANGE. WONDERING IF I HAVE ANY RECOURSE WITH REGARD TO THIS PROBLEM AND THE FACT THAT IT SEEMS A MANUFACTURING DEFECT RATHER THEN NORMAL WEAR AND TEAR. *TR

MAZDA CX-9 PROBLEM 130,000 MILES-ON NOVEMBER 25TH, AS I WAS DROPPING MY CHILDREN TO THEIR SCHOOLS, THE DEFROST SUDDENLY STOPS WORKING. I TRY TO TURN THE FAN/HEATER ALL THE WAY, BUT TO NO AVAIL. I HAD TO USE A TOWEL TO WIPE THE WINDSHIELD. AS I PULLED INTO A CURVED SIDE, THE ENGINE TURNS OFF, I TURNED THE IGNITION KEY TO OFF, THEN STARTS THE ENGINE AGAIN, AND THE ENGINE LIGHT COMES ON. I PULLED OUT AND DROVE ABOUT SIX HUNDRED FEET AND PARKED. I CALL A MECHANIC AND I DROVE IT AGAIN FOR A MILE TO THE SHOP. HE OPENS UP THE HOOD AND POUR IN SOME COOLANT AND ALL THE COOLANT WERE ON THE FLOOR. HE IMMEDIATELY TOLD ME THAT COOLANT LEAKS AND OIL IS PROBABLY MIXED AND CAUSES THE ENGINE FAILURE. HE TOLD ME I HAD TO CHANGE THE ENGINE, BECAUSE FIXING IT WILL COST ME OVER TEN GRAND. I DROVE IT HOME, THEN THE FOLLOWING MORNING, I TOOK TO A DIFFERENT SHOP, THEY DID THE DIAGNOSIS AND RELATE THE SAME STORY THAT CHECK CODES SHOWED THREE CODES: P0016, CRANK POSITION SENSOR CORRELATION BANK ONE SENSOR A. 1285 CYLINDER HEAD OVER TEMPERATURE, 1299 CYLINDER HEAD TEMP PROTECTION. THE CODES INDICATE AN OVERHEAT SCENARIO THAT RESULTED IN ENGINE SHUT DOWN. THEY CHECK OIL AND FOUND MILKY SUBSTANCE INSTEAD OF OIL. PRESSURE CHECK FOR COOLANT LEAK PUSHED MILKY OIL OUT OF DIPSTICK TUBE. HEAD GASKET HAS FAILED DUE TO OVERHEATING AND THE COOLANT HAS CONTAMINATED THE ENGINE OIL. THEIR RECOMMENDATION IS TO REPLACE THE ENGINE, ASSEMBLY AND FLUSH COOLING SYSTEM. THEIR TOTAL ESTIMATE IS $10,900. I CAN'T AFFORD TO PAY FOR THIS SERVICE REPAIR. I CANNOT EVEN SPEND THAT MUCH OF MONEY ON ANOTHER CAR. WE BOUGHT THIS CAR THINKING THAT IT WILL TAKE US FOR SOME TIME BEFORE WE'LL NEED ANOTHER CAR. I CONTACTED MAZDA CUSTOMER EXPERIENCE, AND THEIR RESPONSE WAS, "WISH THERE WERE NEVER PART FAILURES", NOW, I'M STUCK. SO THIS IS MY STORY!!! SAFETY ISSUES: SUDDEN ENGINE SHUT OFF, DEFROST MALFUNCTION AND STEERING WHEEL.

ONE DAY, MY KEYLESS DON STOPPED WORKING. THE NEXT DAY THE DOOR KEPT LOCKING WHILE I WAS DRIVING ALMOST EVERY TIME I TURNED THE STEERING WHEEL. THEN THE DRIVERS DOOR WOULDN'T UNLOCK, WHEN I MANUALLY UNLOCKED THE DOOR IT WAS HARD TO DO. I LUCKILY HAD THE WINDOWS ROLLED DOWN, GOT OUT THE VEHICLE AND AS SOON AS I SHUT THE DOOR I HEAR THE DOOR LOCK AND MY TWO YEAR OLD WAS IN THE BACKSEAT! AGAIN LUCKILY I HAD THE WINDOWS ROLLED DOWN OTHERWISE SHE MIGHT'VE BEEN STUCK! THEN THE ALARM KEPT GOING OFF AND WOULDN'T TURN OFF UNTIL I UNHOOKED THE BATTERY. IMAGINE MY FRUSTRATION. I BROUGHT THE CAR TO A MAZDA DEALERSHIP WHO SAID IT WAS THE DOOR LATCH/ACTUATOR. UPON PAYING HEFTILY WHEN I PICKED UP MY CAR, THE CLICKING OF THE DOOR LOCKS HAD STOPPED BUT THE UNLOCK BUTTON STILL WOULDN'T WORK AND THE ALARM WAS ONCE AGAIN GOING OFF! NOW THE CAR IS STILL AT THE MAZDA DEALERSHIP AND HAD ITS BCM/BCU REPLACED FOR A SUPPOSED 'FIX', I'M SUPPOSE TO PICK IT UP TOMORROW. SO I GUESS WE'LL SEE. THE APPARENT PROBLEM FROM ALL OF THIS? MY CX9 HAS A SUNROOF, WHICH MAZDA KNOWS THESE VEHICLES DON'T DRAIN PROPERLY WHICH CAUSES WATER TO GO TO THE BCM SHORTING IT OUT! THIS IS INEXCUSABLE AND COULD VERY WELL COST SOMEONE'S CHILD THEIR LIFE BECAUSE OF THE DOORS CONSTANT LOCKING AND UNABLE TO UNLOCK SOMETIMES MANUALLY. THE DEALERSHIP HAS SEEN IT ON MORE THAN ONE OCCASION AND MAZDA COMPANY HAS EVEN ADMITTED THIS FAULT! SO WHY IS THERE NO RECALL?!

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

PE11026 · Brake Master Cylinder Leak

Opened Aug 9, 2011 · Closed Apr 9, 2012

Status: closed (inferred from source dates) · Service Brakes, Hydraulic:foundation Components:master Cylinder

The Office of Defects Investigation (ODI) opened PE11-026 to investigate possible brake performance loss due to brake fluid leaking from the master cylinder into the brake booster in model year (MY) 2008 Mazda CX-9 vehicles.In response to ODI's information request letter, Mazda identified a problem with the manufacturing process for the master cylinder primary plunger that could result in inappropriate surface finish.ODI's analysis of complaints and field reports determined that the problem was isolated to several months late in the production of the MY 2008 CX-9 vehicles.Mazda indicated that changes to the plunger machining and inspection processes were incorporated late in MY 2008 vehicle production (June 25, 2008).There are no confirmed failures related to the condition in subsequent production.The subject master cylinder was used by Mazda in MY 2007 through MY 2011 CX-9 vehicles (approximately 132,000 vehicles) with no other significant problems related to master cylinder leakage.ODI's analysis identified a total of 248 complaints and field reports potentially related to the subject condition in MY 2008 CX-9 vehicles.The majority of the records reported that brake malfunction indicator lamp (MIL) illumination was the only symptom of a problem, with only 4% (9 reports) alleging any symptoms related to brake pedal feel or effectiveness.ODI identified no crash claims related to the alleged defect.In addition, analysis of this data showed a declining trend with 90 percent of the incidents reported before January 2011.Based on the extremely slow leak rate associated with the alleged defect, the declining failure trend and the low probability that the condition would affect brake performance, this investigation is closed.The ODI reports cited above can be viewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification numbers (ODI Nos.): 10442322, 10419837, 10449109
