2014 Mazda CX-5

I was waiting at a traffic signal to make a left turn, with my foot on the brake. The car accelerated aggressively, with no warning, like the pedal was pushed to the floor. I stood on the brake and shoved the shifter into park - coming to a stop in the middle of the intersection, Fortunately my wheels were pointed straight and the car did not race into oncoming traffic. My [XXX] father was in the car with me. Thankfully, my grandchildren were NOT in the car. You could smell the gas and brakes. It was NOT driver foot placement, nor was it floor mats. Vehicle has ~ 75K miles, and I am terrified of this happening again. I had driven this car regularly in rush hour stop & go traffic for years with no event like this ever before. Apparently sudden unintended vehicle acceleration is a recognized problem. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

WAS DRIVING WITH FAMILY ON HIGHWAY WHEN CAR STARTED TO FEEL WOBBLY AND I BEGAN SMELLING THE DISTINCT SMELL OF BURNING BRAKES. I PULLED OVER AT THE CLOSES STORE (.5 MILES) . I THEN NOTICED THE REAR, PASSENGER CALIPER WAS SMOKING. I LATER FOUND OUT (AFTER A FEW HUNDRED DOLLARS AND HOURS OF LABOR) THIS IS A KNOWN ISSUE WITH THE REAR CALIPERS SIEZING... APPARENTLY THIS ISN'T CONSIDERED "SAFETY"?!?!. IF I WASN'T MECHANICALLY INCLINED I MAY HAVE KEPT DRIVING. MY SORT RIDE WAS ENOUGH TO HEAT UP AND LOOSEN 2 OF MY LUG NUTS. IF THAT ISN'T A SAFETY HAZARD THEN I DON'T KNOW WHAT IS.

TL* THE CONTACT OWNS A 2014 MAZDA CX-5. THE CONTACT STATED THAT THE BRAKES MADE A SQUEALING NOISE AND FAILED NUMEROUS TIMES. THE VEHICLE WAS TAKEN TO FERRA AUTO GROUP MAZDA (3363 SOUTH ARLINGTON ROAD, AKRON, OH 44312, (330) 645-7275) WHERE IT WAS DETERMINED THAT THE BRAKE PADS WERE WEARING UNEVENLY. THE DEALER FURTHER STATED THAT THE BRAKES REMAINED ENGAGED AND CAUSED THE BRAKE PADS TO WEAR PREMATURELY. THE INNER BRAKE PAD WAS AT A TWO LEVEL AND THE OUTER BRAKE PAD REMAINED AT LEVEL SIX. THE CONTACT WAS INFORMED THAT THE PREMATURE BRAKE PAD WEAR MAY BE CAUSED BY THE CALIPERS AND HYDRAULIC FLEX LINE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 27,000.

AT TIMES THE BREAKS BECOME UNRESPONSIVE TO PRESSURE AND THE PEDAL GOES ALL THE WAY TO THE FLOOR. THE BREAKS HAVE TO BE PUMPED IT ORDER TO GET THEM TO CATCH. SO, I TOOK THE CAR TO A REPAIR SHOP AND THEY CHANGED THE BREAK PADS AND BLEED THE LINES. HOWEVER, AFTER A TEST DRIVE THE ISSUE HAPPENED TO THE MECHANIC AGAIN. AFTER CHECKING THE BREAK SYSTEM AGAIN, THEY FOUND THAT THE VACUUM PUMP IS MALFUNCTIONING. THERE WAS A RECALL FOR OTHER MAZDA CX-5S IN MY MODEL YEAR. BUT MY VIN NUMBER DOES NOT FALL IN THE RECALL. MY AUTO REPAIR PERSON STATED THAT THIS IS SOMETHING THAT SHOULDN'T HAPPEN, AND IS EXTREMELY DANGEROUS.

I HAVE OWNED THIS VEHICLE FOR THREE YEARS AND THE POWER BRAKES HAVE FAILED THREE SEPARATE TIMES. EACH TIME THIS HAPPENS THE PEDAL IS EXTREMELY HARD TO PUSH AND WILL NOT GO DOWN. EACH TIME I WAS DRIVING IN CITY TYPE TRAFFIC. I HAVE TAKEN THE CAR TO JIM ELLIS MAZDA IN MARIETTA GA. THEY WERE UNABLE TO DUPLICATE THE PROBLEM AND RECOMMENDED A BRAKE FLUID FLUSH HAVING SAID THE FLUID WAS DIRTY. ALSO SAID I NEEDED REAR BRAKE PADS DUE TO WEAR BUT THEY WERE FINE.I DID REPLACE THEM WITH NEW AS A PRECAUTION AS I AM A RETIRED AUTOMOTIVE TECHNICIAN. I WILL ATTACH A PHOTO OF THE PADS.THE CAR HAS 49000 MILES ON IT AND WAS PURCHASED CERTIFIED PRE OWNED IN OCTOBER 2016. MY WIFE IS AFRAID TO DRIVE THIS CAR NOW SINCE WE DON'T KNOW WHEN THIS MAY OCCUR AGAIN. EACH TIME THE BRAKES FAILED IT WAS HOT WEATHER AND THE OCCURRENCE WAS SEPT 2ND 2019.

SINCE PURCHASED, THE VEHICLE DRIVER NOTED BRAKE PEDAL WAS "SOFT" WHEN BRAKING THE VEHICLE. THERE WAS NOT ENOUGH PRESSURE IN THE MASTER CYLINDER SYSTEM, IN WHICH THE BRAKE DID NOT RETURN APPROPRIATELY. THE PADS DID NOT PERFORM, SO ALL THE INTERIOR ROUTERS GRINDED. THE VEHICLE HAD CONSISTENT MOVEMENT ON A WEEKLY BASIS AND THE MILEAGE ON THE CAR DOES NOT WARRANT ALL FOUR ROTORS AND PAD HAVING TO BE REPLACED.

WENT IN FOR A SERVICE AROUND 55,000 MILES AND WAS TOLD THAT NEW REAR BRAKES WERE NEEDED. GOT A SECOND OPINION AND WAS TOLD THAT THEY COULD GO A LITTLE LONGER. STARTED HEARING SQUEAKING, TOOK THEM BACK TO THE MECHANIC WHO SAID THEY NEEDED REPLACING. REPLACED AT 59,000 MILES. WENT IN TODAY 7/26/18 AND WAS TOLD MY REAR BRAKES WERE AT 4% AND WOULD NEED REPLACING BY MY NEXT VISIT. THIS WOULD MEAN 2 REAR BRAKE REPLACEMENTS WITHIN 10,000 MILES. MY FRONT BRAKES ARE STILL FINE. I SEE MANY COMPLAINTS ABOUT THIS FOR THE CX 5, THERE A SEVERAL TSBS OUT. CALLED MAZDA WHO SAID THEY WEREN'T AWARE OF THIS PROBLEM AND THAT BRAKES ARE CONSIDERED A NORMAL PART OF WEAR AND TEAR. MY SECOND ISSUES IS THAT WHEN I PUT MY CAR IN PARK AND ATTEMPT TO SHUT IF OFF BUT IT WILL NOT POWER OFF. THIS DOESN'T HAPPEN EVERY TIME, BUT PROBABLY EVERY 4TH OR 5TH TIME. I READ ONLINE THAT IT'S A TRANSMISSION SENSOR ISSUE AND THAT THE TRANSMISSION SENSOR NEEDS REPLACING. BOTH OF THESE ISSUES ARE VERY PREVALENT AND I'M HOPING THERE CAN BE A RECALL ON BOTH.

THE REAR BRAKE PADS ON MY MAZDA CX 5 GRAND TOURING MODEL IS WORN OUT TO (0.2 PER DEALER) AT APPROX 34000 MILES. NOTICED THE PROBLEM WHEN THE CAR STARTED MAKING A GRINDING NOISE FROM THE REAR. BEFORE THIS THERE WAS A VERY STRONG VIBRATION OF STEERING WHEN BRAKING AT SPEEDS OF 55 PLUS MPH. THIS IS VERY UNUSUAL IN MY EXPERIENCE THAT A CAR WHICH IS ABOUT 2 YEARS OLD NEEDS NEW BRAKE PADS AND ROTORS REPLACED. MAZDA WEBSITE HAD SOME INFORMATION HTTP://WWW.CARCOMPLAINTS.COM/MAZDA/CX-5/2013/BRAKES/SERVICE_BRAKES.SHTML. BRAKE ROTORS WERE REPLACED BY MAZDA AT 34000 MILES, NOT MY CAR IS AT 56000 MILES AND INITIAL SYMPTOM WITH THE STRONG VIBRATION OF THE STEERING WHEEL WHEN BRAKING IS REAPPEARING. THIS SEEMS TO INDICATE AN INHERENT PROBLEM WITH THIS MODEL PER INDEPENDENT MECHANICS.

THE BRAKE PEDAL IS SEVERAL INCHES HIGHER THAN THE GAS PETAL IN THIS VEHICLE. IT SLOWS DOWN REACTION TIME WHEN REACTING TO AN EMERGENCY SITUATION. I WAS BACKING INTO A PARKING SPACE. A VEHICLE WENT AROUND ME. I NOTICED THE VEHICLE, BUT WHEN I TRIED TO QUICKLY MOVE MY FOOT TO THE BRAKE MY FOOT GOT HUNG UP ON THE BRAKE PEDAL. THERE WAS AN ACCIDENT WITH NO INJURIES. THE ACCIDENT COULD HAVE BEEN AVOIDED IF I WAS ABLE TO HIT THE BRAKES. AFTER THE ACCIDENT I SAT IN THE PARKING LOT TO ANALYZE AND CORRECT MY MUSCLE MEMORY AND PRACTICE MOVING MY FOOT QUICKLY FROM GAS TO PEDAL. I REALIZED IT TOOK MUCH EFFORT, CONCENTRATION AND QUITE A STRETCH TO GET GET MY FOOT TO THE PEDAL QUICKLY. THE PEDALS SHOULD BE EVEN, OR VERY CLOSE TO EVEN. I DON'T KNOW WHY SOMEONE WOULD THINK THIS IS BETTER, BUT IF IT'S A PREFERENCE THERE SHOULD BE AN ADJUSTMENT. EVEN SHOULD BE THE FACTORY DEFAULT. IT'S COMMON SENSE YOU CAN MOVE MORE QUICKLY STRAIT ACROSS THAN UP AND OVER. THE UNADJUSTIBLE FACTORY POSITION IS OK FOR STANDARD TRAFFIC SITUATIONS, BUT WHEN IN AN UNEXPECTED ENERGENCY SITUATION IT SLOWS DOWN YOUR REACTION TIME CONSIDERABLY. MAZDA SAYS IT'S NORMAN AND ALL NEW CARS ARE THIS WAY. I SAID THAT DOESN'T MAKE IT CORRECT OR ANY LESS OF A SAFETY CONCERN. WHY MAKE A CHANGE THAT SLOWS DOWN REACTION TIME? *TR
