ABOUT A YEAR AGO I BOUGHT 4 NEW TIRES FOR MY MAZDA 3. SIX MONTHS LATER I WENT IN FOR MY ROUTINE ALIGNMENT AND TIRE ROTATION. THEY SAID MY TWO REAR TIRES WERE WORN DOWN TO SHOWING THE WIRING AND COULD POTENTIALLY CAUSE A BLOW OUT. THEY REFUSED TO PUT THE TIRES BACK ON FOR SAFETY CONCERNS. I HAD TO PURCHASE TWO USED TIRES THAT HAD ABOUT THE SAME MILEAGE MY OTHER TIRES HAD ON THEM. AGAIN 5-6 MONTHS LATER I GO INTO LES SCHWAB FOR MY TIRE ROTATION AND ALIGNMENT AND AGAIN THEY TELL ME MY TWO REAR TIRES ARE SHOWING EXCESSIVE WEAR. WHEN COMPLAINING ABOUT HAVING TO GET TIRES SO SOON THEY STATED THAT MAZDA DESIGNED THE CAR THIS WAY TO HAVE A TOE IN ALIGNMENT. BASICALLY THIS WILL BE A RECURRING ISSUE UNLESS I PUT A $500 CAMBER KIT ON THE BACK. WHEN I ASKED ABOUT THAT THEY SAID IT MAY CHANGE THE WAY THE CAR HANDLES AND HAVE LOUDER ROAD NOISE. NONE OF THIS WAS MENTIONED BY MAZDA WHEN I PURCHASED THAT CAR BACK IN 2008. NOT ONLY IS THIS ISSUE CAUSING ME TO SPEND MONEY EVERY 5-6 MONTHS BUT IF I WERE TO GO TO LONG WITHOUT CHECKING MY TIRES I COULD HAVE A BLOWOUT WHILE DRIVING, POSSIBLY CAUSING AN ACCIDENT, INJURY OR DEATH. I SEE THIS AS BEING A VERY BIG ISSUE WITH THE MAZDA AND I WOULD LIKE TO SEE MAZDA HAVE TO RECALL AND FIX THIS PROBLEM. *TR

TPMS LIGHT ALERTED LOW TIRE PRESSURE CONDITION. FOUND TIRE WITH LOW PRESSURE. DURING INSPECTION OF TIRE, A SMALL AIR LEAK WAS DISCOVERED AT THE VALVE STEM MID SECTION OF THREADS DUE TO CORROSION. THE TPMS SENSOR ASSEMBLY REPLACEMENT WAS NECESSARY TO CORRECT THE FAILURE. APPROXIMATELY EIGHTEEN MONTHS AFTERWARDS, THE SAME EXACT FAILURE RE-OCCURRED IN ANOTHER TPMS SENSOR. THE ALUMINUM ALLOY VALVE STEMS ON THESE SENSORS ARE HIGHLY SUSCEPTIBLE TO CORROSION DAMAGE AND NEED TO BE RE-CALLED. THIS FAILURE IS A COMMON PROBLEM WITH THESE SENSORS, ESPECIALLY WHERE VEHICLES EQUIPPED WITH THESE ARE DRIVEN WHERE ROAD "SALTING" IS ROUTINE. THE POTENTIALLY DANGEROUS LOW TIRE PRESSURE CONDITION CAUSED BY THESE FAULTY STEMS MAY LEAD TO AN ACCIDENT RESULTING IN DEATH. *TR
THE TIRE PRESSURE MONITORING SYSTEM SEEMS TO BE OVERSENSITIVE THE WARNING LIGHT STAYS ON EVEN WHEN THE TIRES ARE PROPERLY INFLATED. *TR

APPROXIMATELY THREE YEARS AFTER PURCHASE, I GOT A FLAT TIRE DRIVING ON 1-290 IN CENTRAL MASSACHUSETTS. WHEN I LOOKED AT THE ISSUE, IT WAS CLEAR THAT THE TIRE SENSOR VALVE HAD GONE INTO THE TIRE. I REPLACED SAID TIRE, AND SINCE THEN I HAVE THE ISSUE THREE MORE TIMES ON ALL FOUR TIRES TOTAL. THE SECOND AND THIRD TIME WERE TWO CONSECUTIVE DAYS APRIL 2013 AND THE FOURTH ONE TODAY 12/17/13. THE SENSORS SEEMED TO BE ROTTING OUT AND THE STEM ENDS UP CORRODING. I HAVE SPENT AT LEAST 1,000 IN THE LAST YEAR AND A HALF FIXING THIS ISSUE AND IT IS VERY INFURIATING TO SAY THE LEAST. IT SEEMS THAT LOOKING ONLINE THIS IS AN ISSUE WHICH MANY HAVE HAD, YET THERE HAS BEEN NO RECALL. *TR

I GOT A FLAT TIRE YESTERDAY BECAUSE MY TIRE PRESSURE SENSOR VALVE HAD FALLEN INSIDE MY TIRE. THIS IS THE SECOND TIME THAT THIS HAS HAPPENED SINCE I PURCHASED THE VEHICLE IN 2008. THANKFULLY, I WAS STUCK IN RUSH HOUR TRAFFIC AND ONLY GOING 20 MPH. I REALIZED MY TIRE WAS FLAT WHEN THE SENOR LIGHT WENT OFF AND MY CAR VEERED TO THE LEFT AND FORTUNATELY IT WAS THE EMERGENCY LANE OR I WOULD HAVE HIT A CAR. TOOK IT TO THE SERVICE SHOP AND THE TPS SENSOR NOW NEEDS REPLACED BECAUSE IT HAD CORRODED AND DAMAGED THE INSIDE OF MY TIRE AS WELL. WHEN THE MECHANIC LOOKED AT MY OTHER TIRES AND TPS SENSOR/STEM VALVE WAS CORRODED. THE THIRD TIRE IS FINE FOR NOW BUT IS SHOWING SIGNS OF CORRODING AS WELL. THE 4TH ONE WAS REPLACED A COUPLE YEARS AGO AND APPEARS OK. MAZDA NEEDS TO RECALL THIS PROBLEM ASAP AND REIMBURSE EVERYONE THAT HAS HAD TO FIX THIS ISSUE. I COULD HAVE BEEN IN A SERIOUS ACCIDENT IF I WAS GOING ANY FASTER THAN 20MPH. ITS SAD THAT SOMEONE HAS TO GET SERIOUSLY HURT OR DIE FOR A RECALL TO HAPPEN. TO REPLACE BOTH SENSORS AND FIX MY TIRE I GOING TO BE PAYING OVER $300 FOR MAZDA'S ISSUE. I TAKE GREAT PRIDE AND CARE OF MY CAR, I BOUGHT IT NEW; NOTHING ON THAT CARE SHOULD BE CORRODING WHEN IT IS ONLY 5 YEARS OLD. THIS IS RIDICULOUS THAT SO MANY PEOPLE ARE HAVING THE SAME ISSUE. NOT OUR FAULT AS CONSUMERS THAT THIS IS HAPPENING, FIX THIS NOW MAZDA!! *TR
TL* THE CONTACT OWNS A 2008 MAZDA, MAZDA3. THE CONTACT STATED THAT AS HE SAT IN THE VEHICLE, THE VALVE STEM BECAME FRACTURED. THE FAILURE WAS RECURRING. THE VEHICLE WAS TAKEN IN FOR REPAIR AND DIAGNOSED AS VALVE STEM CORROSION. THE MANUFACTURER WAS MADE AWARE OF THE ISSUE. THE APPROXIMATE FAILURE MILEAGE WAS 58,000.
I CANNOT BELIEVE THAT MAZDA HAS NOT RECALLED THE TPMS ON THE 2008 MAZDA 3'S. ALL OF THE TPMS HAVE HAD TO BE REPLACED ON MY VEHICLE. CURRENTLY, I WILL BE GETTING THE LAST TWO FIXED/REPAIRED COMING THIS MONDAY. ALL OF THEM WERE EITHER CRACKED OR CORRODED. THE FIRST INCIDENT RESULTED IN ONE OF MY TIRES BEING "SHREDDED" ON THE I…

I CANNOT BELIEVE THAT MAZDA HAS NOT RECALLED THE TPMS ON THE 2008 MAZDA 3'S. ALL OF THE TPMS HAVE HAD TO BE REPLACED ON MY VEHICLE. CURRENTLY, I WILL BE GETTING THE LAST TWO FIXED/REPAIRED COMING THIS MONDAY. ALL OF THEM WERE EITHER CRACKED OR CORRODED. THE FIRST INCIDENT RESULTED IN ONE OF MY TIRES BEING "SHREDDED" ON THE INSIDE. PART OF THE KIT BROKE OFF AND WAS INSIDE THE RIM. I WAS ACCUSED BY A DEALERSHIP THAT I MUST HAVE BEEN DRIVING ON A FLAT TIRE. I CAN'T BELIEVE HOW MANY TIMES THE TPMS WARNING LIGHT HAS COME ON. THIS IS OBVIOUSLY A DEFECTIVE PART. MAZDA SHOULD BE RECALLING THIS. *TR

THE ISSUE RESULTED IN SIGNIFICANT PULL TO THE LEFT SIDE AND LOST OF AIR/FLAT TIRE ON THE FRONT DRIVER SIDE WHEEL. THE REASON BEHIND THIS FAULT WAS A DEFECTIVE VALVE STEM. AFTER INSPECTING ALL THE OTHER WHEELS, IT TURNS OUT ALL THE VALVE STEMS ARE CRACKED. SOME INITIAL RESEARCH TELLS ME ITS A COMMON PROBLEM AMONG THOSE CARS AND MAZDA WILL NOT DO ANYTHING TO FIX IT. AT THIS POINT I HAVE CALLED MAZDA DEALERSHIP AND MAZDA CORPORATE OFFICE AND NONE OF THEM WILL DO ANYTHING ABOUT THIS SAFETY ISSUE. TOTAL COST OF REPAIR WILL BE 4X $120 FOR ALL TPMS SENSORS WITH VALVE STEMS AND 2X $115 FOR BOTH FRONT TIRES. HOPEFULLY THERE IS A RECALL COMING SOON... *TR

The subject vehicles have electro-hydraulic power assist steering (EHPAS).The complaint counts shown above alleged a loss of power steering assist in the subject vehicles.Usually, but not always, the loss is accompanied by the simultaneous lighting of an indicator light on the dash.The complaints include 14 alleged crashes involving 6 injuries.On Mazda3 and Mazda5 vehicles manufactured from April 2, 2007 through November 30, 2008, rust may have formed inside the EPAS high-pressure pipe during manufacture due to improper processing.If the rust is present it may damage the power steering pump bearings leading to an increased load on the electric motor; this results in an elevated operating temperature for the EPAS system.To prevent excessive overheating of the system, which could potentially cause permanent damage, afailsafe mode which de-powers the electric pump is implemented.This causes a loss of power assist making it more difficult to steer the vehicle, especially at lower vehicle speeds.Once the failsafe is implemented the EPAS system will remain disabled until the ignition is turned off.However EPAS will be re-enabled if the operating temperature is reduced (i.e., within an acceptable range) on a subsequent drive cycle.On August 8, 2010 Mazda submitted a Part 573 defect information report initiating Safety Recall 10V-374 to remedy the subject vehicles.The report, which contains additional details on the remedy repair, is available at http://www-odi.nhtsa.dot.gov/recalls/.ODI notes that the affected population shown in that report includes approximately 8,000 vehicles Mazda repaired prior to initiating the recall.
