2010 MAZDA CX-7 Complaints

A FLAPPING SOUND DEVELOPED IN THE ENGINE COMPARTMENT WHILE TRAVELING ON INTERSTATE 35W. BATTERY LIGHT CAME ON AND LOSS OF POWER STEERING. EXITED THE FREEWAY TO A PARKING LOT. OPENED THE HOOD AND THE BROKEN ENGINE BELT WAS WRAPPED AROUND THE ENGINE PULLEY ONLY, WITH SHREDDED PIECES OF IT STUCK THROUGHOUT THE ENGINE COMPARTMENT. TOWED TO A REPAIR SHOP AND WAS DIAGNOSED TO HAVE A FAULTY BELT TENSIONER AND/OR BELT WAS NOT INSTALLED CORRECTLY AT THE FACTORY. CONTACTED MAZDA USA AND WAS ADVISED THAT IT IS NOT COVERED UNDER THE BASIC 3 YEAR/36000 MILES WARRANTY OR THE POWER TRAIN 5 YEAR/60000 MILES WARRANTY. *TR

LOSS OF POWER WHEN TRYING TO ACCELERATE. PUFF OF WHITE SMOKE ALONG WITH A CLACKING NOISE. *TR

WHEN DRIVING WITH THE A/C ON, THE ECM SEEMS TO MALFUNCTION AND INCREASE THE SPEED OF THE CAR WHEN THE AC COMPRESSOR TURNS ON. IF YOU ARE IN THE PROCESS OF BRAKING, THE CAR WILL NOT STOP AND IT WILL REQUIRE THE DRIVER TO PRESS HARDER ON THE BRAKES. THE CAR GETS AND EXTRA BOOST OF ENERGY AND EVEN THOUGH YOU ARE BRAKING, THE CAR LUNGES FORWARD AND CONTINUES TO ROLL FURTHER. IF THE DRIVER IS CAUGHT OFF GUARD, THIS WILL LEAD TO AN ACCIDENT. I CRASHED MY CAR INTO A FAMILY MEMBERS HOUSE AS I WAS PARKING. LUCKILY, THE PARKING BUMPER SLOWED DOWN THE CAR ENOUGH SO AS TO ONLY SLIGHTLY BUMP THE HOUSE. IT HAS HAPPENED IN REGULAR TRAFFIC AS WELL. LUCKILY, I KEEP A SAFE DISTANCE FROM CARS AND BRAKE EARLY BUT NOW I BRAKE EVEN EARLIER JUST IN CASE. VOLKSWAGEN HAD THE SAME PROBLEM AND THEY DID A LARGE RECALL ON THE VEHICLE BECAUSE OF THE SAFETY ISSUE IT INVOLVES. IF YOU OWN A CX-7 KEEP AN EYE OUT FOR THIS, ESPECIALLY WHEN THE A/C IS ON. IT ONLY HAPPENS WHEN THE TIMING IS JUST RIGHT THAT YOU ARE BRAKING AND THE COMPRESSOR TURNS ON A THAT PRECISE MOMENT SO IT WILL CATCH YOU OFF GUARD AND SCARE THE DAYLIGHTS OUT OF YOU. I'VE BEEN LUCKY SO FAR BUT THIS COULD DEFINITELY CAUSE MAJOR DAMAGE IF NOT RECALLED IN ORDER TO FIX. HERE IS THE INFO FROM A RECALL FROM VOLKSWAGEN. VOLKSWAGEN IS RECALLING APPROXIMATELY 4,000 OF ITS CARS. THE AUTOMAKER WILL FIX ENGINE CONTROL MODULE SOFTWARE THAT CAN TRIGGER AN UNEXPECTED INCREASE IN ENGINE RPM, ACCORDING TO THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION. "THESE VEHICLES HAVE AN ENGINE CONTROL MODULE CONTAINING SOFTWARE THAT MAY NOT PROPERLY CONTROL ENGINE IDLE WITH THE AIR-CONDITIONING TURNED ON," NHTSA SAID IN ITS SUMMARY OF THE PROBLEM. "IN RARE CASES, THE ECM MAY UNEXPECTEDLY INCREASE ENGINE RPM. AN ENGINE SURGE CAUSED BY AN UNEXPECTED INCREASE IN ENGINE RPM MAY SURPRISE THE VEHICLE OPERATOR AND CAN RESULT IN A CRASH WITHOUT WARNING." *TR

MY 2010 MAZDA CX7 HAS BEEN IN DIRE NEED OF NEW TIRES. I HAVE HAD SEVERAL REPAIRS FROM PUNCTURES IN THE TIRES WHICH ARE BRIDGESTONE DUELER 215/70R17 WHICH IS MY UNDERSTANDING THAT THEY ARE SOFT TIRES AND THE RATING IS NOT THAT GREAT ON THIS TYPE OF TIRE BUT IT IS THE ONLY TIRE RECOMMENDED FOR THIS MODEL. THIS IS THE ONLY TIRE RECOMMENDED THROUGH MAZDA. THEY ARE ALSO EXPENSIVE. I AM VERY UPSET THAT MAZDA GIVES NO ALLOWANCE OF THE BRAND TIRE THAT A CONSUMER MAY CHOOSE. EVEN THE MAZDA DEALER THAT I BOUGHT FROM DIDN'T HAVE THEM IN STOCK. I FEEL THIS HAS BEEN MISREPRESENTATION ON THE DEALER'S PART AND MAZDA. I HAVE BEEN READING FORUMS OF THIS PROBLEM AND IT IS RECOMMENDED TO REPLACE EVERY YEAR BECAUSE OF TYPE OF TIRE. I LIVE IN FLORIDA AND DO NOT NEED WINTER TIRES. IS THERE ANYTHING I CAN DO? I AM TEMPTED TO CONTACT EVERY TIRE DEALER AND MEDIA. *TR

WHILE ON INTERSTATE THE TIRE PRESSURE SENSOR ILLUMINATED. HUSBAND CHECKED ALL TIRES AND DISCOVERED THAT ONE OF THE VALVE STEMS WAS BROKEN. THE OUTSIDE WAS CORRODED. THE SLIGHTEST PRESSURE ON IT WAS RELEASING AIR AT A RAPID RATE. WE HAD ONLY JUST PURCHASED THE CAR A WEEK BEFORE. HOW THIS WAS NOT CAUGHT BY THE SERVICE DEPARTMENT AT THE DEALERSHIP IS BEYOND ME. THE DEALERSHIP REPLACED THE STEM, BUT WE WERE TOLD THAT THIS IS A COMMON PROBLEM. REALLY? THEN WHY AREN'T THERE ANY RECALLS ON THIS? AFTER READING THE OTHER NUMEROUS COMPLAINTS ABOUT OUR MODEL, I AM BECOMING INCREASINGLY NERVOUS OVER OUR HASTY PURCHASE. RESEARCH IS KEY IN CHOOSING A VEHICLE. *TR

NEW HEADRESTS SINCE 2010 ARE TERRIBLE. MY NECK CONSTANTLY HURTS BECAUSE I LIKE TO SIT AGAINST THE BACK OF MY SEAT, AND MY HEAD IS PUSHED FORWARD AT AN ANGLE NO MATTER HOW I TRY TO ADJUST THE HEADRESTS IN MY CX7. THESE "SAFETY" REGULATIONS ARE CAUSING ME PAIN AND PERMANENT NECK ISSUES. THESE SAFETY REGULATIONS NEED TO BE REVISED. *TR

TL* THE CONTACT OWNS A 2010 MAZDA CX-7. THE CONTACT STATED THAT AFTER THE ENGINE WAS STARTED, THERE WAS A RATTLING NOISE COMING FROM UNDER THE ENGINE. THE VEHICLE WAS TAKEN TO THE DEALER AT LEAST TEN TIMES WHO REPLACED THE MOTOR MOUNTS, RING SEAL, CONVERTER, GASKET AND MAIN PIPE, BUT THE FAILURE RECURRED. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 1,000 AND THE CURRENT MILEAGE WAS 27,000. UPDATED 4/11/13 *CN THE CONSUMER STATED THE REMOTE KEY WOULD NOT WORK AT TIMES. UPDATED 04/18/13

I PURCHASE THE MAZDA CX7 ON MARCH 20 2010. WITHIN 3 WEEKS I NOTICE A RATTLING NOISE FROM THE ENGINE WHEN START UP THE CAR. I TOOK IT TO 2 DIFFERENT LOCAL MAZDA DEALERS OVER 8 TIMES SINCE PURCHASE AND THEY REPLACED 3 MOTOR MOUNT BUT THE PROBLEM STILL EXIST. THIS YEAR I TOOK IT TO THE DEALER TWICE AND THEY REFUSED TO FIX IT. THEY WOULDN'T EVEN SCHEDULE AN APPOINTMENT TO LOOK AT MY CAR. MY CAR IS STILL UNDER WARRANTY. I TOOK MY CAR TO 2 DIFFERENT CERTIFIED MECHANICS AND THEY BOTH ACKNOWLEDGE THAT THE RATTLING NOISE DOES EXIST.I NEED HELP FIXING THIS PROBLEM. I READ ONLINE AND SAW LOTS OF COMPLAINT ABOUT THIS PROBLEM. SOME WERE ABLE TO GET IT RESOLVE BUT THEY WOULDN'T FIX MY ISSUE. *TR

TL* THE CONTACT OWNS A 2010 MAZDA CX7. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 35 MPH, HE HEARD A LOUD WHINING NOISE AND WAS UNABLE TO ACCELERATE THE VEHICLE. THE CONTACT ALSO STATED THAT THE TURBO FAILED. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE TURBO NEEDED TO BE REPLACED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE AND CURRENT MILEAGE WAS 50,100.

2010 CX7 GRAND TOURING WAS PURCHASED WITH 5,844 MILES FROM DEALER. WE CHANGED THE OIL & FILTER EVERY 6,000 MILES USING RECOMMENDED OIL AS SHOWN IN THE OWNERS MANUAL (5W20). MANUAL RECOMMENDATION IS TO CHANGE OIL EVERY 7,500 MILES WITH NORMAL DRIVING CONDITIONS WHICH IS THE CASE AS MY WIFE DROVE TO AND FROM WORK. AT 37,000 MILES, VEHICLE WAS STARTED IN 20DEG F. TEMPS, WARMED UP FOR AND EXPERIENCED LOUD ENGINE KNOCK. ONCE DRIVEN, VEHICLE HAD NO POWER AND HAD TROUBLES GETTING TO HWY SPEED. DROVE THE VEHICLE TO THE DEALER WHERE WE PURCHASED IT THE NEXT DAY AND WAS INFORMED THE ENGINE HAD EXCESSIVE ENGINE OIL SLUDGE UNDER THE OIL FILLER CAP. SERVICE DEPT. CALLED ME THE NEXT DAY AND SAID THEY WOULD NEED TO PULL THE VALVE COVER TO INVESTIGATE FURTHER TO SEE IF MAZDA NATIONAL WOULD COVER UNDER WARRANTY. WE AGREED SINCE WE PROPERLY MAINTAINED THE VEHICLE AND HAD NOTHING TO HIDE. TWO DAYS LATER WE RECEIVED A CALL FROM THE DEALER AND WERE INFORMED THERE WAS EXCESSIVE SLUDGE AND THEY WOULD NEED TO SEE RECEIPTS FROM WHERE WE CHANGED OUR OIL. WE PERFORMED OUR OWN OIL CHANGES AND DID NOT KEEP RECEIPTS FROM THE AUTO PARTS STORE WHERE WE PURCHASED THE OIL. DEALER SAID WITHOUT THE RECEIPTS WE WOULD NOT GET WARRANTY WORK DONE AND CHARGED US $260 TO DO THE INVESTIGATION TO BETTER THEIR CASE. I CALLED NATIONAL MAZDA AND ALL THEY DID WAS READ THE NOTES FROM THE DEALER AND WERE NOT WILLING TO BUDGE. THE REP FROM MAZDA ([XXX]) WAS EXTREMELY RUDE AND COULD CARE LESS WE WERE EXPERIENCING MAJOR ISSUES WITH A CAR WITHIN THE WARRANTY. THERE ARE NUMEROUS CLAIMS SIMILAR TO OURS ALL OVER THE INTERNET. IT APPEARS MAZDA HAS THEIR STANDARD "EXCESSIVE ENGINE SLUDGE" PITCH DOWN AS THIS IS THE COMMON THEME IN ALL CX7 ENGINE PROBLEMS. WE HAD THE ENGINE REBUILT AT A LOCAL SHOP (PAID $6,100) AND NOW ARE TOLD THE TURBO IS SHOT AS WELL WHICH IS ESTIMATED AT ANOTHER $2,000 TO REPLACE. *TR
