SERVICE BRAKES

124 complaints

I was driving normally when I started sowing down and noticed the brakes were harder to push. I finally stopped just before almost rear-ending a vehicle in front of me. It turns out the brake booster, a known problem that was not communicated to me a few years ago, failed and makes braking the vehicle harder, increases distance, and makes the vehicle unsafe to drive. The problem has been reproduced via a diagnostic test at Mazda of Gladstone dealership on 9/27/23. The dealership has been the only people who have inspected the issue. There were no warning signs, no warning lights, nothing. It was scary because I didn't think my vehicle was going to stop. It's completely dangerous. I have not gotten the vehicle repaired yet because I believe Mazda holds responsibility as this has been a known issue with their cars.

Sep 29, 2023

On August 14, 2020, the brake booster along with the master cylinder failed, resulting in very dangerous and frightening driving conditions, and the parts were replaced with Mazda original parts. This was an ongoing issue with the Mazda CX-9’s. I reported it to the NHTSA, complaint number 11480067. On January 4, 2023, the brake master cylinder and booster failed again resulting again in very dangerous and frightening driving conditions. The car was driven only 25,383 miles before the brakes failed the second time. The Mazda parts were defective and continue to be so after many years with no effort by Mazda to improve these parts. Attached are the repair invoices for both incidents. I have tried contacting Mazda and they refuse to address the issue.

Feb 20, 2023

The brakes suddenly became very difficult to press as if I did not have power brakes. No warning lights came on and it became very difficult to stop the car. Then if I had to break suddenly and hard it would stall. I brought it to the repair shop and the brake booster was defective. The brake booster along with the master cylinder had to be replaced. It was a very dangerous and frightening experience the brakes suddenly difficult to use. I contacted Mazda customer service and they did not care. I then tried to escalate the issue over the last two years but it was impossible to contact anyone and all emails came back undeliverable. I just recently learned that I can report this danger to the NHTSA.

Brake power boost failure

Jun 20, 2022

This is relating to NHTSA Investigation PE 14-005. Although this car is a 2012 Mazda CX9, my wife driving the car had the same issue where she heard a hissing noise and the brakes were very difficult for her to depress or to stop. A brake issue is a major defect where the NHTSA should have initiated a recall in accordance with 49 U.S.C. 30118-30120, which required notification of all owners. Why the NHTSA allowed Mazda to only issue a 'Special Extended Warranty' is beyond me, and smells of a back door deal. Nonetheless, I was unaware of this issue with the Mazda CX9's as I was never notified. My wife drove the vehicle home and I purchased the replacement parts at my own expense. This should be a full recall and should be reopened as your current investigation PE 14-005 only included years 2010-2011, and did *not* include the 2012 model year.

AIR BAGS

19 complaints

My driver and passenger side curtain airbags randomly deployed without a collision. Thankfully I was at a stop sign when this happened. If it happened while I was driving, I’m sure I would have wrecked and could possibly be dead. It was loud! I thought I’d been shot or that I’d driven over a bomb. We did take the car to someone that’s certified in airbags and it was stated that this was due to a manufacturer’s defect. I also have lots of pictures. There was no warning when the airbags deployed. Mazda is refusing any responsibility due to the car being outside of the warranty.

CAR IDELS UP AT STOP SIGNS

Jan 07, 2022

MY WIFE WAS DRIVING DOWN A CITY STREET WHEN THE CAR COMPLETELY SHUT DOWN AND LOST ALL POWER. LUCKILY, SHE WAS ABLE TO STOP WITHOUT CAUSING AN ACCIDENT. WE HAD CAR TOWED TO AN INDEPENDENT MECHANIC. AFTER INSPECTION WE WERE TOLD THE WATER PUMP HAD FAILED CAUSING COOLANT TO LEAK INTO THE ENGINE AND CAUSED COMPLETE ENGINE FAILURE. WE WERE QUOTED $8K-$10K TO REPLACE THE ENGINE. THE 2012 MAZDA CX-9 ONLY HAD 99K MILES, BUT UNFORTUNATELY OUR EXTENDED WARRANTY EXPIRED A FEW YEARS AGO, SO MAZDA WAS OF NO HELP. WE WERE LEFT TO JUNK OUR CAR FOR A FRACTION OF WHAT IT'S VALUE SHOULD HAVE BEEN. APPARENTLY THIS IS A KNOWN ISSUE AND WE WILL BE JOINING THE CURRENT CLASS ACTION LAWSUIT AGAINST MAZDA.

Sep 29, 2020

IN OCT. 2019 MY CX9 STOPPED WHILE BEING DRIVEN. FOUND OUT THE WATER PUMP (WHICH IS INSIDE THE ENGINE) HAD GONE OUT AND DESTROYED MY ENGINE. THIS IS A KNOWN PROBLEM OF WHICH MAZDA HAS FAILED TO MAKE THEIR CONSUMERS AWARE. I PURCHASED THIS CARE NEW AND ALL OF MY SERVICES HAD BEEN HANDLED BY MAZDA. NO-ONE TOLD ME ABOUT THIS PROBLEM AND I STILL HAD TO PAY JUST OVER 4K TO GET A NEW ENGINE OF THE SAME STUPID DESIGN PUT IN MY CAR. THIS IS VERY DANGEROUS PROBLEM. HOW MANY MAZDA DRIVERS HAVE BEEN INJURED OR KILLED IN CRASHES BECAUSE THE WATER PUMP DESTROYED THE ENGINE ON A FREEWAY AND THE CAR CEASING TO MOVE WAS THE CAUSE OF AN ACCIDENT THAT TOTALED THE CAR AND AS A RESULT WENT UNDETECTED? THE ENGINES NEED TO BE RECALLED.

Jul 01, 2020

TL* THE CONTACT OWNS A 2012 MAZDA CX-9. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THE VEHICLE STALLED WITHOUT WARNING.

THE CONTACT WAS INFORMED THAT THE ENGINE WAS DAMAGED DUE TO A WATER PUMP FAILURE. THE VEHICLE WAS TOWED BACK TO THE HOME AND LATER REPAIRED BY AN INDEPENDENT MECHANIC HOWEVER, THE FAILURE RECURRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 109,000. THE VIN WAS NOT AVAILABLE.

Jan 10, 2020

VEHICLE STALLED WHILE EXITING THE HIGHWAY, ENGINE LIGHT ON, NOISE FROM TIMING CHAIN AREA, VEHICLE OVERHEATS, WATER PUMP FAILURE PUSHES ANTIFREEZE INTO THE OIL COMPARTMENT CAUSING THE ENGINE TO GET DAMAGED WITHIN MINUTES WHITEOUT A WARNING. THIS IS OBVIOUSLY A MAJOR VERY EXPENSIVE SAFETY ISSUE.

SUSPENSION

9 complaints

The contact owns a 2012 Mazda CX9. The contact stated that the vehicle had previously been involved in a crash due to a fractured passenger's side lower control arm. 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. The failure mileage was approximately 110,000.

TL* THE CONTACT OWNS A 2012 MAZDA CX9. THE CONTACT STATED THAT WHILE DRIVING AT AN UNDISCLOSED SPEED, THE VEHICLE SHUT-OFF WITH AN UNKNOWN WARNING LIGHT ILLUMINATED. THE VEHICLE WAS TAKEN TO TWO INDEPENDENT MECHANICS WHO DIAGNOSED THAT WATER ENTERED THE VEHICLE AND CAUSED THE CORROSION OF THE FRONT SUSPENSION BALL JOINT. THE DEALER WAS NOT CALLED.

THE CONTACT WAITED FOR AT LEAST FOUR MONTHS WITH NO CONTACT FROM THE DEALER FOR RECALL REPAIRS. THE CONTACT HAD NOT EXPERIENCED A FAILURE. PARTS DISTRIBUTION DISCONNECT.

Feb 16, 2017

I RECEIVED A LETTER IN SEPTEMBER 2015 REGARDING A RECALL THAT INVOLVED THE FRONT SUSPENSION AND THE DANGERS THAT COULD BE INVOLVED, BUT THERE WERE NO PARTS AVAILABLE AT THIS TIME TO FIX THE PROBLEM. I STILL HAVEN'T RECEIVED NOTIFICATION OF PARTS BEING AVAILABLE 6 MONTHS LATER. NO DAMAGE HAS BEEN DONE MY VEHICLE AS OF YET HOWEVER ANOTHER SNOWY WINTER IN ILLINOIS HAS PASSED AND THE DANGER OF "SALTWATER INTRUDING INTO THE BALL JOINT, CAUSING CORROSION, WHICH CAN RESULT IN GENERATING LOOSENESS OF THE BALL JOINT IN THE FITTING". THE RESULT OF THIS CORROSION, ACCORDING TO THE RECALL LETTER, CAN CAUSE THE BALL JOINT AND LOWER ARM TO SEPARATE CAUSING LOSS OF STEERING CONTROL AND INCREASED CRASH RISK. I THINK 6 MONTHS IS AMPLE TIME TO PRODUCE PARTS NEEDED TO FIX THESE VEHICLES AND TO SAVE LIVES AND IT IS INCREDIBLY IRRESPONSIBLE OF MAZDA TO NOT EXPEDITE THIS FIX.

POWER TRAIN

The water pump suddenly started leaking and the mechanics I talk to said this is a very common problem with this vehicle and type of engine. Sounds like owners are left to foot the bill for this costly and difficult repair of a defective product. Hopefully more owners come forward and report their experience in this regard

11/1/2016- AT 92,205 MILES VEHICLE SHUDDERED WHEN I STEPPED ON ACCELERATOR. I WAS TOLD IT WAS TRANSMISSION RELATED. ON MY WAY TO MECHANIC VEHICLE COMPLETELY SEIZED; HAD TO HAVE IT TOWED TO TRANSMISSION SHOP. ANGLE GEAR HAD TO BE REPLACED BECAUSE TRANSFER CASE OIL BURNED OFF BECAUSE CATALYTIC CONVERTER IS PLACED TOO CLOSE AND IT COOKS LUBRICANT. I WAS TOLD THIS IS A KNOWN PROBLEM WITH MAZDA CX9'S. COST 1,400. MAZDA WAS UNWILLING TO COVER REPAIRS AT ALL. 6/22/2020 - 130,000 MILES SAME SHUDDERING HAPPENED WHEN STEPPED ON ACCELERATOR AND SAME ISSUE. CALLED MAZDA AND SAME RESPONSE 'NOT OUR PROBLEM, IT'S OUT OF WARRANTY'. *TR

Jun 23, 2020

THE TRANSMISSION WAS SHIFTING HARD BETWEEN 4TH AND 5TH GEAR. MY WIFE BROUGHT THE VEHICLE TO THE DEALERSHIP TO HAVE THE AIR BAG RECALL DONE. THEY THEN CHARGED US $122 TO UPDATE THE TRANSMISSION PROGRAM TO CORRECT THE FACTORY ISSUE. NOW IT SHIFTS FROM 6TH TO 3RD ON THE INTERSTATE.

Dec 28, 2018

AWD TRANSFER CASE UNIT FAILURE THE TRANSFER CASE OF MY 2012 MAZDA CX-9 FAILED WHILE DRIVING ON THE HIGHWAY AT CRUSISING SPEED CREATING A DANGEROUS SITUATION. THE FIRST SIGN OF FAILURE WAS A HEAVY BURNED OIL ODOR. THE ODOR WAS CAUSED BY A LOT OF OIL POURING OVER THE EXHAUST PIPE WHICH ALSO WAS A DANGER OF FIRE. AFTER INSPECTION MECHANIC FOUND THAT THE TRANSFER CASE HAD A LEAK AND THE COUPLING SPLINES BETWEEN THE TRANSMISSION AND THE POWER TRANSFER CASE AND THE RIGHT DRIVESHAFT WERE EXTREMELY CORRODED, THIS CORROSION WAS NOS EVIDENT FROM OUTSIDE BECAUSE EITHER THE TRANSMISSION AND THE TRANSFER CASE ARE MADE OF ALUMINUM AND THE DRIVESHAFT IS INSERTED THROUGH THE POWER TRANSFER UNIT INTO THE TRANSMISSION, BUT FOR UNKNOWN REASONS, THE TRANSMISSION OUTPUT AND TRANSFER CASE INPUT PARTS WHICH ARE MADE OF STEEL ARE BADLY CORRODED AND GOT SEVERELY WORN WITH A LOT OF RUST ACCUMULATION IN PLACE, WHICH IN TIME WILL CAUSE A TRACTION LOSE THAT WOULD SEVERELY COMPROMISE DRIVING SAFETY. MAZDA ISSUED A BULLETIN TO ADDRESS THE POWER TRANSFER CASE UNIT BUT IS LIMITED TO 7 YEARS OR 90000 MILES WHICH IS A LOW MILEAGE FOR A PROBLEM LIKE THIS TO DEVELOP AND WHEN THE OWNER TRIES TO TAKE ACTION MAZDA WILL NOT COVER THE REPAIRS. I THINK THI IS A MANUFACTURING QUALITY CONTROL ISSUE SINCE ITS COMPLETELY BEYOND THE ACTIONS OR FAILURE OF THE OWNER TO FOLLOW A PROPER MAINTENTANCE SCHEDULE SINCE THE OWNERS MANUAL DOESNT SAY ANYTHING ABOUT IT. HTTPS://STATIC.NHTSA.GOV/ODI/TSBS/2014/CSC-10055535-7382.PDF MAZDA DOES NOT HAVE A SERVICE SCHEDULE FOR THIS PART AND IS CONSIDERED TO BE MANTENTANCE FREE HOWEVER, IF THE ISSUED THE SERVICE BULLETIN IS BECAUSE THEY KNOW THIS PART HAS POTENTIAL ISSUES. THE INVOLVED PARTS SHOULD BE REPAIRED BY MAZDA SINCE IS A DESIGN OR MANUFACTURE PROBLEM. THANK YOU FOR YOUR ATTENTION TO THIS MATTER.

I JUST HAD ONLY 33K MILES ON MY 2012 MAZDA CX-9, THE TRANSFER CASE BROKEN FROM INSIDE YESTERDAY MORNING (FRIDAY APRIL 6TH 2018) WHEN I COMMUTE FROM HOME TO WORK. I WAS DRIVING ON A NEIGHBORHOOD ROAD GO STRAIGHT. FIRST THE LOUD NOISE RAISE FROM UNDER HOOD THEN THE SUV LOST POWER. LUCKILY I HAVE ROOM TO PULL OVER AND PARK IT AT SIDE OF THE ROAD. IT DID PUT ME AND PUBLIC IN DANGER BY THE FAULTY TRANSFER CASE. I HAVE TO CALL A TOW TRUCK TO GET MY SUV TO AUTO SHOP. SERVICEMAN CALLED ME THIS MORNING AND TOLD ME THAT I NEED TO REPLACE THE BAD TRANSFER CASE.

Crash: 1

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.

BRAKE BOOSTER FAILED WHILE DRIVING CAUSING BREAK ABILITY TO FAIL COMPLETELY. CAR COULD NOT STOP. REALLY DANGEROUS SITUATION.

Aug 13, 2016

I EXPERIENCED UNEXPLAINED SUDDEN ACCELERATION WHILE STOPPED AT A STOP LIGHT. AT THE TIME OF THE INCIDENT THERE WAS ONE CAR STOPPED IN FRONT OF ME AND ONE BEHIND ME. FROM THE ONSET OF THE INCIDENT IT TOOK JUST A VERY FEW SECONDS, PROBABLY BETWEEN TWO AND FOUR, FOR THE ENGINE TO REV TO AN EXTREMELY HIGH SPEED. WHILE THIS WAS HAPPENINGS I COULD FEEL THE VEHICLE ATTEMPTING TO MOVE FORWARD FORCEFULLY WHILE I WAS APPLYING THE BRAKES VERY HARD. I SHIFTED INTO NEUTRAL AND TURNED OFF THE IGNITION. I THEN SHIFTED INTO PARK. I TURNED THE IGNITION ON AGAIN AND THE ENGINE CONTINUED TO REV AT A VERY HIGH SPEED. I IMMEDIATELY SHUT OFF THE ENGINE. I DECIDED TO START THE VEHICLE ONE MORE TIME. THIS TIME WHEN I TURNED ON THE IGNITION THE VEHICLE RAN NORMALLY. I CAUTIOUSLY DROVE IT FOR POSSIBLY FIVE MILES AND PARKED IT WHERE I COULD HAVE IT TOWED TO THE DEALERSHIP. I WAS ASKED ABOUT FLOOR MATS.THE ORIGINAL FLOOR MATS WERE IN THE VERY BACK OF THE VEHICLE AND I HAD WEATHERTECH MATS, IN THE FRONT OF THE CAR, WHICH WERE ATTACHED TO HOOKS IN THE FLOOR HOLDING THEN IN PLACE. THE DEALERSHIP DID TAKE THE SITUATION VERY SERIOUSLY. THEY DID INDICATED CONCERN ABOUT HAVING THE VEHICLE ON THE ROAD AGAIN. THEY TESTED THE VEHICLE FOR ANY COMPUTER CODES WHICH MIGHT INDICATE WHAT MAY HAVE CAUSED THE PROBLEM AND FOUND NOTHING. THEY CONTACTED MAZDA AND AT THE TIME THAT I SOLD THE CAR BACK TO THE DEALERSHIP THEY HAD NOT HEARD ANYTHING FROM MAZDA.

BOTH MY TAIL LIGHTS FORM CONDENSATION. I CONTACTED BOTH THE DEALER AND THE CORPORATION SEVERAL TIMES. THE CORPORATION MAINTAINS THIS IS A NORMAL OCCURRENCE THAT COMES AND GOES DEPENDING ON THE WEATHER CONDITIONS. CONSEQUENTLY THEY DON'T CONSIDER THIS A WARRANTY ISSUE, AS A RESULT THEY WON'T DO ANYTHING TO REMEDY THE PROBLEM. THE SERVICE MANAGER FROM THE DEALERSHIP INFORMED ME THAT THEY USE TO REPLACE THE FAULTY UNIT UNTIL MAZDA REFUSED TO REIMBURSE THEM. THEIR EXCUSE SEEMS TO BE ABSURD CONSIDERING THE UNIT SHOULD BE SEALED. *TR

After hearing low rumbling sound and smelling burnt oil, car was taken to dealer for check up. They informed me of known issue, front PTU leaking oil due to design flaw that put the PTU so close to the exhaust. I am seeing that other owners of this model are also reporting fires due this same exact problem, apparently unbeknownst to me Mazda has provided extended warranty up to 90k miles but not actually informed the owners of this as a potential catastrophic problem. my personal review has informed me that fire seem to be most common between 110,000 and 130,000 mile ranges.

I OWN A 2012 MAZDA CX9, WHICH I PURCHASED NEW. ON MONDAY MORNING (NOVEMBER 12, 2018) MY (CHECK ENGINE LIGHT CAME ON) AND SO I TOOK IT IMMEDIATELY TO THE DEALERSHIP FOR DIAGNOSIS. MY CAR WAS RUNNING BEAUTIFULLY, SO I JUST ASSUMED WITH THE WEATHER CHANGE, PERHAPS THE GAS CAP WASN'T TIGHTENED, AND THEY JUST NEEDED TO CLEAR THE CODES. IT TURNS OUT THE WATER PUMP FAILED AND APPARENTLY DESTROYED THE ENTIRE ENGINE. WHICH BECAME APPARENT AS I DROVE IT TO THE DEALERSHIP FOR DIAGNOSIS, PER THEIR RECOMMENDATION. MY CAR IS WELL MAINTAINED BASED ON THE DEALER RECOMMENDATIONS AND IS CONSISTENTLY SERVICED AT THE MAZDA DEALERSHIP. THE CAR IS IN FANTASTIC CONDITION WITH ONLY 90,000. AS AN OWNER, I DID EVERYTHING BY THE BOOK IN TERMS OF MAINTENANCE FOR MY CAR. I AM LETTING YOU KNOW, MAZDA HAS A SERIOUS PROBLEM AND IT'S A SAFETY ISSUE, AS WELL. IF A WATER PUMP CAN JUST FAIL WITHOUT WARNING AND COMPLETELY SHUT DOWN AN ENGINE, THAT'S NOT GOOD. I THINK THIS IS FAR MORE DANGEROUS THAN THE AIR BAG RECALL, WHICH IS ONLY A CONCERN IF YOU GET IN AN ACCIDENT. THERE IS NO WARNING ON THE WATER PUMP FAILING, AS IT'S SELF-CONTAINED WITHIN THE POWER TRAIN AND THE ONLY WAY TO CHECK THIS PART IS BY REMOVING THE ENTIRE ENGINE, WHICH LEADS ME TO BELIEVE THIS PART WAS NOT DESIGNED TO BE A WEAR PART. IT'S AN ENGINEERING DESIGN FLAW, THAT CAN CAUSE BODILY HARM IF IT FAILS, BECAUSE IT TAKES OUT THE ENTIRE ENGINE AND YOU LOSE CONTROL OVER THE VEHICLE.

AT JUST OVER 90,000 MILES I HAD TRANSFER CASE PROBLEM THAT EVERYONE IS POSTING. AS DESCRIBED BY MECHANIC IT IS A MANUFACTURING DEFECT. TRANSFER CASE IS PLACED JUST ABOVE CATALYTIC CONVERTER (WHICH THROWS OFF ALOT OF HEAT) AS A RESULT OIL IN TRANSFER CASE COOKS OVER TIME AND GEARS ARE DESTROYED. MAZDA DID NOT PROVIDE A WAY TO REPLACE AND OR CHECK THIS FLUID WITHOUT TAKING DOWN THE ENTIRE TRANSMISSION. MECHANIC SAID I WILL HAVE THIS PROBLEM AGAIN AT ROUGHLY ANOTHER 80-100,000 MILES. YEAR AND A HALF LATER I NOTICED A VERY SOFT BRAKE. I REPLACED BRAKE PADS AND DRUMS, AND BRAKE FLUID. I HAVE A VERY HARD BRAKE WHICH THEN SPORATICALLY GOES SOFT. AGAIN I LOOKED UP THIS ISSUE AND FOUND AGAIN MAZDA IS AWARE OF THIS ISSUE AND EXTENTED WARRANTY TO 90,000 MILES. AGAIN I'M JUST OVER THE WARRANTY ALLOWANCE AND NOW MY BRAKE POWER BOOSTER AND POSSIBLY MASTER CYLINDER NEED TO BE REPLACED. BOTH ARE KNOWN ISSUES BY MAZDA. UNFORTUNATELY I WAS THE LUCKY ONE WHO WAS THE BENEFICIARY OF BOTH PROBLEMS JUST OVER THE 90,000 MILE WARRANTY. I REACHED OUT TO MAZDA TO REQUEST SOME ASSISTANCE WITH AT LEAST THE COST OF THE PARTS ON THE BRAKE POWER BOOSTER. I WAS GIVEN A QUICK NO BY MAZDA. VERY FRUSTRATING SINCE THESE ARE BOTH KNOWN PROBLEMS AND THEY WILL NOT AT LEAST WORK WITH ME ON THE PARTS COST.

THE MAZDA CX9 THAT WE PURCHASED HAS A ACCELERATION PROBLEM WHEN WE GO TO STOP.. MAZDA HAS NEVER BEEN ABLE TO SOLVE THE PROBLEM COMPLETELY.. WE HAVE HAD 2 BRAKE BOOSTERS REPLACED UNDER WARRANTY. WE FEEL THE CAR IS UNSAFE TO DRIVE AND MAZDA HAS NOT ADDRESSED THE PROBLEM. THEY TELL US NOTHING IS WRONG WITH THE CAR. IT KNOW ALSO HAS TRANSMISSION PROBLEMS WITH SQUEAKING AND GRINDING NOISES COMING FROM THE CAR. THIS IS A DESIGN FLAW THAT HAS NOT BEEN ADDRESSED.

MULTIPLE TRIPS TO THE DEALERSHIP AND AN INDEPENDENT MECHANIC AND THE CHECK ENGINE LIGHT (CEL) COMES ON WITH A DIAGNOSIS OF EVAPORATING SYSTEM / LOOSE GAS CAP. MULTIPLE DIAGNOSTICS FEES, A GAS TANK PRESSURE TEST AND 3 GAS CAPS LATER AND THE PROBLEM HAS NOT BEEN FIXED. I NOTICED A FEW ONLINE FORUMS WITH SEVERAL OTHERS COMPLAINING OF THE SAME ISSUE ACROSS A WIDE RAGE OF YEARS AND MAZDA MODELS. THERE IS A DESIGN PROBLEM WITH MAZADA EVAPORATING, FUEL AND EMISSIONS SYSTEMS. THE DEALER CANNOT IDENTIFY THE PROBLEM. BEYOND REPLACING THE GAS CAP AND COLLECTING A DIAGNOSTIC FEE.

WE HAVE NOTICED THE DIFFICULTY IN DEPRESSING THE BRAKE PAD ALONG WITH THE HISSING NOISE OVER THE PAST 1 MONTH AND IT HAS PROGRESSIVELY BECAME STRONGER. INITIALLY YOU BRUSH IT OFF THINKING YOU ARE IMAGINING IT. TODAY ON A HILL THERE WAS AN ACCIDENT SO TRAFFIC WAS BARELY MOVING, I STARTED TO LEAVE MORE AND MORE DISTANCE WITH THE VEHICLE IN FRONT OF ME AS IT WAS BECOMING INCREASINGLY DIFFICULT TO DEPRESS THE BRAKES. FINALLY I HEAR A STRANGE NOISE AND THEN COMPLETE QUIET AND MY TEENAGE DAUGHTER NOTICES TOO AND AS I RELEASE THE BRAKE TO MOVE I REALIZE THE CAR ENGINE HAD DIED (THE ENGINE HAS NEVER GIVEN ANY INDICATION OF ISSUES BEFORE) BUT THE ENGINE DASH LIGHTS WEREN'T ON INDICATING THERE WAS NOT POWER WHICH OF COURSE MEANS NO POWER STEERING EITHER, A QUICK SHIFT TO N AND RESTART AND ALL IS FINE THE REST OF THE WAY HOME. THE HISSING NOISE AND DIFFICULT DEPRESSION CONTINUED HOWEVER WHILE ON THE HILL WHEN I DID PRESS HARD ENOUGH FOR THE BRAKES TO RESPOND THEY DID SO AS THOUGH BYPASSING THE ANTI-LOCK SYSTEM AS THEY WOULD JOLT INTO THE STOP. VERY CONCERNING AS THE DISTANCE TO STOP HAS INCREASED, WHAT IF A PERSON WALKED IN FRONT OF ME MUCH LESS IF I'M ON THE FREEWAY AND COME UPON A SUDDEN NEED TO STOP. BUT HERE IT IS A SATURDAY EVENING AND HOW AND WHEN CAN I DEAL WITH AN OBVIOUS SAFETY ISSUE THAT CLEARLY IS REPEATED. I WONDER HOW MANY OUT THERE HAVE NOT TAKEN THE TIME TO REPORT, HAVE SPENT MUCH ON REPAIRS OR SIMPLY TRADED IN THEIR VEHICLE TO COME IN TO THE HANDS OF SOME OTHER UNSUSPECTING CONSUMER. ACTION TRULY IS NEEDED BEFORE SOMEONE'S LIVES ARE CHANGED FOREVER.

WHILE DRIVING ON INTERSTATE 90 WEST IN MASSACHUSETTS, 5 MILES FROM ROUTE 84, OUR AWD CX-9 STARTED MAKING A VERY LOUD WHINING NOISE. WITHIN 10 SECONDS, THE CAR STARTED BUCKING, MAKING A GRINDING NOISE AND THE STEERING BECAME DIFFICULT. I WAS ABLE TO MANEUVER TO THE LEFT SIDE OF THE ROAD; I COULD NOT MAKE IT TO THE BREAKDOWN LANE BECAUSE OF THE CAR'S CONDITION. ONCE THE CAR STOPPED, WE SMELLED BURNING FLUID AND SOME SMOKE CAME OUT OF THE VENTS INSIDE THE CAR. THE CAR WAS UNABLE TO DRIVE ON ITS OWN, THE WHEELS SEEMED LOCKED AND THE GRINDING NOISE WAS EXTREMELY LOUD WHEN IN DRIVE OR NEUTRAL. I HAD TO CALL 911. THE MASS STATE HIGHWAY PATROL ARRIVED AND HAD TO PUSH US OVER TO THE BREAKDOWN LANE WHILE THE CAR WAS IN NEUTRAL. THE THE MASS STATE POLICE HALTED ALL TRAFFIC ON THE HIGHWAY FOR THIS TO OCCUR. WE SAT IN THE BREAKDOWN LANE FOR AN HOUR WAITING FOR A TOW TRUCK. THIS ENTIRE SITUATION WAS VERY DANGEROUS. I HAD A TODDLER IN THE CAR WITH US. THE HIGHWAY WAS ONLY MOVING AROUND 35-40 MILES AN HOUR AND SLOWING AT THE TIME OF THE INCIDENT. THE MASS STATE HIGHWAY PATROL AND TOW TRUCK DRIVER STATED THAT THE CAR MAY HAVE SPUN OUT OR FLIPPED IF THE HIGHWAY WAS MOVING AT SPEED DUE TO SUCH A CATASTROPHIC STEERING FAILURE. THE CX-9 HAD STARTED MAKING A OCCASIONAL QUIET WHINING SOUND IN THE DAYS PRIOR TO THE FAILURE, ON OUR DRIVE FROM VIRGINIA TO MASS . THERE WAS NO OTHER WARNING, NO WARNING LIGHTS ON THE DASH AT ALL. THE CAR WAS TOWED TO THE CLOSEST MAZDA DEALERSHIP AND WAS DIAGNOSED WITH AN INTERNAL FAILURE IN THE TRANSFER CASE. THE REPAIR WAS COVERED UNDER OUR POWER TRAIN WARRANTY, AS THE CAR ONLY HAD 28,764 MILES AT THE TIME OF THE INCIDENT AND IS 3 YEARS OLD.THE MAZDA DEALER SAID THERE HAVE BEEN NUMEROUS TRANSFER CASE FAILURES IN AWD CX-9S. I WANT TO SEE THIS PART RECALLED BECAUSE THIS FAILURE CREATED A VERY DANGEROUS SITUATION FOR MY FAMILY.

I AM UNSURE OF THE FIRST DATE OF OCCURRENCE, BUT THE FOLLOWING HAVE BEEN HAPPENING SINCE I PURCHASED THIS VEHICLE NEW WITH 12 MILES ON IT. AND THE DEALER CAN'T FIND ANYTHING WRONG WITH IT. 1. THE AC ALWAYS COMES ON. EVEN WHEN IT'S BELOW ZERO OUTSIDE. 2. IT FAILS TO GO WHEN PUSHING ON THE ACCELERATOR FREQUENTLY, AND ESPECIALLY IN REVERSE, FROM A STOPPED POSITION, UNTIL YOU REALLY PUSH HARD ON THE ACCELERATOR CAUSING IT JUMP. 3. LAST FRIDAY 2/21/2014 AS I WAS ON A RAMP MOVING FROM ONE INTERSTATE TO ANOTHER, THE ENGINE CONTINUED TO REV UP EVEN AFTER I LET OFF THE GAS, AND PUSHED THE BRAKE. THIS IS NOT THE FIRST OCCURRENCE OF THIS, IT'S ACTUALLY HAPPENED AT LEAST 10-12 TIMES. IT WAS DEFINITELY THE MOST SCARY, AS I THOUGHT I WAS GOING OVER THE SIDE OF THE RAMP OR INTO THE SEMI IN FRONT OF ME FOR A MINUTE OR SO. 4. THE BRAKES SQUEAK LOUDLY WHEN IT'S COLD. 5. THE BRAKES ARE EITHER REALLY SENSITIVE, OR YOU HAVE TO STOMP THEM TO GET THEM TO WORK, SO SINCE YOU DON'T KNOW WHICH IT'S GOING TO BE YOU'RE LIKELY TO JERK YOURSELF AND YOUR PASSENGERS AROUND A LOT. 6. THE VEHICLE PULLS TO ONE SIDE OR THE OTHER, WHICH WOULD SEEM TO INDICATE THAT AN ALIGNMENT IS NEEDED, HOWEVER, IT CAN'T PICK WHICH SIDE IT'S GOING TO GRAVITATE TOWARDS WHICH LEADS ME TO BELIEVE IT'S SOMETHING IN THE STEERING. *TR

I HAVE A MAZDA 2012 THAT SPONTANEOUSLY STALLS WHILE DECELERATING. IT ALSO STALLS PREDICTABLY ON AN INCLINE. MAZDA CORPORATION HAS STATED "THE STALLING ON AN INCLINE IS A CHARACTERISTIC OF ALL CX-9 MODELS" AND ARE NOT WILLING TO FIX IT. THEY HAVE INFORMED ME THAT STALLING WHILE DECELERATING IN MY CAR HAS NOT BEEN ABLE TO BE RECREATED BY THEIR TECH SO THEY ARE DOING NOTHING ABOUT IT. I HAVE BEEN IN TWO NEAR MISS ACCIDENTS. THE CAR LOSES POWER STEERING AND BRAKING AND THE DRIVER HAS LITTLE TO NO CONTROL WHEN IT STALLS. PLEASE WATCH THIS VIDEO OF A BRAND NEW (LOANER FROM THE DEALER WHILE THEY LOOKED AT MY 2012 CX-9) 2013 CX-9 (125 MILES ON IT). THIS IS THE "CHARACTERISTIC" I AM REFERRING TO, PLEASE ADVISE FUTURE BUYERS OF THIS VERY UNSAFE "CHARACTERISTIC". WHEN IT STALLS IN MY DRIVEWAY, I CANNOT BRAKE "SHARPLY" OR EFFECTIVELY ENOUGH TO STOP THE CAR FROM DRIFTING INTO THE ROAD. HTTP://YOUTU.BE/PBZHVIEIHKC. *TR
