2007 Mazda CX-7 Tires & wheels Problems

One of the Prinx HiCountry HT2 tires (size 235/60R18) developed a structural failure shortly after installation. The tire repeatedly lost air with no visible puncture. I first took it to a local tire shop, which could not locate the source of the leak. The problem continued, so I brought the tire to a second independent tire shop, where a technician inspected it and confirmed the issue was caused by a thin steel belt wire protruding through the tread near the shoulder area. They marked the defect with white tire chalk and determined the tire was not repairable under safety guidelines. The failure originated from inside the tire, not from an external object. The tire is still in my possession and available for inspection. No warning lights appeared prior to the failure; the only symptom was repeated pressure loss.

I HAVE A 2007 MAZDA CX-7. IT IS A VERY BEAUTIFUL CAR BUT ALSO HAS TONS OF PROBLEMS. AT 15000 MILES IT WAS LEAKING OIL AND THEY REPLACE THE ENGINE GASKETS. THEN LATER WAS ALSO LEAKING OIL. WAS TOLD BY THE DEALER THAT IT WAS NOT. TOOK IT TO SOMEONE ELSE WHO SAID IT WAS LEAKING FROM THE TIMING CHAIN. MAZDA RESEALED IT. SINCE THEN MY CAR DOESN'T SHIFT PROPERLY GOING UP AND DOWN HILLS. MY AIR CONDITIONER IS HOT AND MAKES A FUNNY SOUND. MY CAR HAS LOSS OF POWER AND SOUND LIKE A DIESEL. OVERALL I THINK THAT MAZDA NEEDS TO STEP UP AND TAKE CARE OF THE PROBLEMS OR THEY WILL NOT GET MANY RETURNING CUSTOMERS! SOMETHING NEEDS TO BE DONE! IT WAS A 35000 DOLLAR CAR! *TR

APPROXIMATELY THREE WEEKS AGO, I NOTICED INCREASING DIFFICULTY MANEUVERING MY CAR AND TWO WEEKS AGO, AS I TURNED ONTO MY STREET, (TRAVELING AT APPROXIMATELY 5 MPH), MY CAR ACTUALLY SLID ACROSS THE INTERSECTION AND INTO THE CURB ON THE OPPOSITE SIDE OF THE STREET. FORTUNATELY, NO PEDESTRIANS WERE NEARBY AND NEITHER MY CAR NOR I SUSTAINED ANY INJURY. CURIOUS AS TO WHY THIS WOULD HAVE OCCURRED, MY HUSBAND INVESTIGATED AND MUCH TO OUR DISMAY, WE DISCOVERED THAT MY BRIDGESTONE TURANZA TIRES ' WITH JUST 18,800 MILES ON THEM ' WERE BALD EXCEPT FOR THE GROOVES THAT RUN ALONG THE CIRCUMFERENCE OF THE TIRE. AT THIS TIME, WE CALLED TWO AREA BRIDGESTONE DEALERS WHO JOINTLY CONSENTED THAT THE TIRE HAD NO TREAD WEAR WARRANTY WHICH FURTHER SERVED TO REINFORCE THE FACT THAT BRIDGESTONE IS AWARE THAT THE TURANZA IS A POOR QUALITY TIRE NOT WORTHY OF WARRANTY. WHEN QUESTIONED ABOUT THE POOR STATE OF THE TIRES AFTER JUST 18,800 MILES, THEY INDICATED, THAT OTHER THAN THE FACT THAT THE TURANZA WAS A 'CHEAP' TIRE (THEIR SPECIFIC VERBIAGE), IT COULD ALSO BE DUE TO POOR DRIVER HABITS OR AN OUT-OF-ALIGNMENT VEHICLE OR BOTH. BECAUSE I AM THE SOLE DRIVER OF MY VEHICLE AND COMMUTE JUST 21 MILES ROUND-TRIP TO MY JOB VIA A STATE-MAINTAINED ROAD WITH A MAXIMUM SPEED LIMIT OF 50 MPH, POOR DRIVER HABITS IS ELIMINATED. FURTHERMORE, INVESTIGATION ALSO REVEALED THAT THE CAR WAS, IN FACT, NOT OUT-OF-ALIGNMENT, AS WE HAVE NOW REPLACED ALL FOUR TIRES ON THE VEHICLE AND CONFIRMED THAT THE ALIGNMENT WAS FINE. FRANKLY, WE FIND IT NOTHING SHORT OF DESPICABLE THAT BRIDGESTONE CONTINUES TO SELL THESE TIRES WHEN FULLY AWARE OF ITS POOR QUALITY AND IT IS PARTICULARLY DISHONORABLE THAT YOU ARE WILLING TO RISK PEOPLES' LIVES BECAUSE THEY ARE UNKNOWINGLY DRIVING ON INFERIOR, NON-WARRANTED TIRES. *TR

I HAVE A MAZDA 2007 CX 7 WITH BRIDGESTONE TIRES. I HAVE 25,480 MILES AND DO NOT CARRY ANYTHING HEAVY. THE CAR IS USUALLY USED FOR LOCAL TRAVEL WIH 1 PERSON IN IT AND NO MORE THAN 2, BOTH OF US TOGETHER WEIGH LESS THAN 300 LBS. TWO OF MY TIRES HAVE TO BE REPLACED AND ANOTHER ONE WITHIN THE NEXT 1000 MILES. PEOPLE WHO HAVE PURCHASED THIS MODEL HAVE BEEN COMPLAINING ABOUT TIRES WEARING OUT AT 22,000 MILES AND MAZDA NOR BRIDGESTONE WILL DO ANYTHING ABOUT IT. THIS IS A POTENTIAL PROBLEM IN WHICH TIRES WILL BLOW OUT CAUSING EITHER PROPERTY DAMAGE OR LOSS OF LIFE. I HAVE NOT REPLACED THE TIRES YET, SO THEY ARE AVAILABLE FOR INSEPCTION. PEOPLE PURCHASING THESE AUTOMOBILES SHOULD HAVE BEEN TOLD THAT THESE TIRES WEAR OUT AT AROUND 22K MILES, SINCE I WOULD HAVE EITHER ASKED TO HAVE THE TIRES REPLACED OR I WOULD NOT HAVE PURCHASED THE CAR. WHEN YOU PURCHASE TIRES FROM A AUTO SHOP, THEY INDICATE THE NORMAL WEAR OF THE TIRE. ALL NEW AUTOS SHOULD HAVE THE SAME REQUIREMENT. I THINK THAT BRIDGESTONE USED INFERIOR RUBBER TO MAKE THESE TIRES SINCE THE WEIGHT OF THE AUTO MAY HAVE AN EFFECT ON THE WEAR OF THE TIRES. *TR

I PURCHASED A 2007 MAZDA CX-7 FROM DIAMOND MAZDA IN BATON ROUGE, LA. I HAVE ALWAYS BEEN UNDER THE ASSUMPTION THAT A SET OF TIRES ON A NEW VEHICLE WOULD LAST ME AT LEAST TILL I PAID OFF THE LOAN WHICH WOULD BE 5 YEARS. I HAVE PURCHASED OTHER VEHICLES AND NEVER HAD THIS PROBABLY BEFORE NOW. THIS IS THE FIRST TIME THAT I HAVE BOUGHT A MAZDA AND PROBABLY MY LAST. I AM VERY DISAPPOINTED ABOUT THE RUN AROUND THAT I AM GETTING FROM BRIDGESTONE/FIRESTONE TIRE RETAILERS. I WAS TOLD THAT THIS MAZDA CX-7 IS A HEAVY VEHICLE AND THAT THE TIRES ARE ONLY WARRANTY FOR 16,000 MILES I HAVE NEVER HEARD ANYTHING LIKE THAT BEFORE IN MY LIFE. IF I HAVE TO BUY TIRES EVERY YEAR I WILL GO BROKE. MY MAZDA CX-7 HAS 16,000 MILES ON IT AND THE TIRES ARE WORN TO WHERE THEY ARE SLICK. THEY ARE VERY DANGEROUS AND FOR ME TO BUY SOME NEW TIRES WILL COST ME $750.00. I HAD NO IDEA THAT THIS WOULD HAVE HAPPEN TO ME AFTER ONLY HAVING THE CAR FOR ONE YEAR. I SEE THERE ARE OTHER COMPLAINTS ON THE SAME ISSUE. THERE SHOULD BE A RECALL ON THESE TIRES. *TR

MY HUSBAND AND I PURCHASED 2 MAZDA CX-7'S IN OCT 07. IN SEPT 2008 1 VEHICLE AFTER JUST 13,000 MILES ON IT HAD EXCESSIVE AND ABNORMAL WEAR ON ALL 4 OF THE TIRES. WE HAVE BEEN ADVISED NOT TO DRIVE MUCH ON THESE TIRES IN THE CONDITION THEY ARE IN BY 4 SEPARATE OPINIONS WE RECEIVED FROM THE DEALERSHIP, TIRE MANUFACTURER AND 2 ADDITIONAL TIRE RETAILERS. WE HAVE HAD 1 FLAT TIRE DURING THE PROCESS OF GETTING THESE TIRES REPLACED HOWEVER NEITHER THE DEALERSHIP, CAR MANUFACTURER NOR THE TIRE MANUFACTURER WOULD STAND BEHIND THE FAULTY EQUIPMENT. ALL AGREED THAT THE TIRES SHOULD NOT WEAR THAT EXCESSIVELY HOWEVER EACH BLAMING THE OTHER FOR THE PROBLEM. SEVERAL POSTS ON THE INTERNET STATE THE SAME PROBLEM WITH THIS TIRE AND THIS VEHICLE! I FEEL I HAVE THE RIGHT TO HAVE SAFE EQUIPMENT ON MY VEHICLE AND I AM LOOKING FOR SUPPORT TO KEEP MY PASSENGERS AS WELL AS OTHER'S WHO MAY BE DRIVING THIS CAR WITH THESE TIRES SAFE. I WOULD LIKE TO MENTION THAT THE OTHER VEHICLE OF THE SAME MAKE AND MODEL BOUGHT ON THE SAME DAY HAS A DIFFERENT TIRE ON THE CAR AND THAT CAR HAS NORMAL WEAR AND TEAR.. TO ME THIS IS EVIDENCE THAT SOMETHING IS NOT RIGHT WITH THIS CAR AND THIS TIRE. *TR

MAZDA CX7 (FWD) EXHIBITS ABNORMAL TIRE WEAR(CUPPING,FEATHERING) ON ALL (4) TIRES AFTER LESS THAN 1000 MILES. BROUGHT THE CAR INTO THE PURCHASING DEALER WHO RE-BALANCED AND REALIGNED. TIRES CONTINUED TO EXHIBIT THE SAME WEAR AFTER 2000 MILES AND RIDE AT HIGHWAY SPEEDS HAD SOME VIBRATION AND ROUGH FEEL AT LOWER SPEEDS. DEALER ONCE AGAIN REALIGNED VEHICLE AND INCREASED THE PSI ON ALL 4 TIRES TO 36PSI. AT JUST OVER 5000 MILES VEHICLE WAS BROUGHT INTO DEALER AGAIN, STILL CONTINUING TO SHOW ABNORMAL WEAR AND POOR RIDE AT HIGHWAY SPEEDS (VIBRATION & ROUGH). DEALER REALIGNED AND RE-BALANCED ALL WHEELS AND ONCE AGAIN INCREASED TIRE INFLATION TO 36PSI. I LATER CONTACTED THE SERVICE MGR AND TOLD HIM THAT I DID NOT LIKE THE FACT THAT HE INCREASED THE TIRE PRESSURE OVER THE MANUFACTURERS RECOMMENDED SETTINGS AND THAT THIS WOULD CAUSE THE TIRE TO WEAR DOWN THE CENTER QUICKLY. *JB
