2008 MAZDA CX-7 Complaints

WHINING SOUND WHEN GAS PEDAL IS COMPRESSED, FORM 30 - 65 MPH, AT TIMES ,LOSS OF POWER. *TR

DRIVING APPROXIMATELY 55 - 60 MPH ON AN EXTREMELY COLD (-20) MORNING. TRIED TO BRAKE AND BRAKE IS VERY HARD AND DOES NOT STOP. AFTER PUMPING THE BRAKE SEVERAL TIMES, IT GRABS AND BRAKES PROPERLY. THIS IS THE FOURTH TIME THIS HAS HAPPENED IN AN APPROXIMATE 30 DAY PERIOD (ALL DURING EXTREME COLD). TOOK CAR TO DEALER AND THEY FIND NOTHING WRONG WITH THE BRAKE SYSTEM. I HAVE SUBSEQUENTLY FOUND THE ARTICLES ABOUT THE NHTSA OPENING AN INVESTIGATION INTO BRAKING PROBLEMS ON THE MAZDA CX-9 THAT SOUND IDENTICAL TO THE PROBLEM I HAVE BEEN EXPERIENCING. *TR

HAD TO REPLACE THE A/C COMPRESSOR THAT WENT BAD, WAS A RECALL ON THEM BUT MY WARRANTY WAS OUT. THEN NOW 11/8/13 I AM BEING TOLD THAT MY EGR VALVE IS BAD AND NEEDS TO BE REPLACED AND IT SO HAPPENS GUESS WHAT THE EMISSIONS WARRANTY HAS RAN OUT. I HAVE SEEN A LOT OF COMPLAINTS ON LINE ABOUT THE A/C COMPRESSOR AND NOW THE EGR VALVE. *TR

TL* THE CONTACT OWNS A 2008 MAZDA CX-7. THE CONTACT STATED THAT WHITE SMOKE EMITTED FROM THE TAIL PIPE. THE VEHICLE WAS TAKEN TO THE DEALER WHO STATED THAT THE FAILURE WAS DUE TO POOR MAINTENANCE AND THAT THE TURBO NEEDED TO BE REPLACED. THE CONTACT ALSO MENTIONED THAT THE FAILURE WAS PREVIOUSLY EXPERIENCED. THE TECHNICIAN ALSO STATED THAT THERE WAS A BLOWN HEAD GASKET. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED ABOUT THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 81,000. UPDATED 12/31/13*CN THE DEALER INFORMED THE CONSUMER THE TURBO FAILED DUE LACK OF MAINTENANCE AND NOT ENOUGH OIL CHANGES.

SUDDEN LOSS OF POWER AS THE TURBO STOPPED WORKING. THE MAZDA DEALERSHIP CLAIMED THAT THE TURBO BROKE DUE TO SLUDGE IN THE ENGINE. THERE WAS A LOT OF SLUDGE IN THE ENGINE, HOWEVER, THE CAR WAS WELL MAINTAINED WITH REGULAR OIL CHANGES. IT SEEMS THAT THE MEDIAN ENGINE TEMPERATURE IS HOTTER THAN IS APPROPRIATE FOR THE SPECIFIED OIL IN THE OWNERS MANUAL. THIS RESULTS IN OIL BURNING AND STICKING TO THE INSIDE OF THE ENGINE. EVENTUALLY A PIECE OF "SLUDGE" WILL COME LOOSE AND CLOG THE OIL TUBE TO THE TURBO, RESULTING IN THE TURBO UNIT OVERHEATING AND BREAKING. MAZDA SEEMS TO BE AWARE OF THIS PROBLEM AS THEY WERE PRESSURED TO EXTEND THE WARRANTY ON THIS PART. HOWEVER, THE PROBLEM IS VERY SERIOUS AND THERE SHOULD BE A RECALL OF THE TURBO UNIT AND CLARIFICATION IN THE OWNER'S MANUAL. MAZDA HAS YET TO AGREE TO FIX THE TURBO AND "SLUDGE" IN MY ENGINE. THEY ARE STILL INSISTING THAT I DID NOT MAINTAIN THE VEHICLE WELL. FYI- I WAS A CAR DESIGNER WITH HONDA/ACURA FOR 4 YEARS WHO DESIGNED THE 2009 - 2012 MDX. I AM STATING THIS BECAUSE I KNOW SUV'S AND HOW TO MAINTAIN THEM VERY WELL. *TR

TL* THE CONTACT OWNS A 2008 MAZDA CX7. THE CONTACT STATED THAT WHILE THE VEHICLE WAS PARKED AND UNOCCUPIED, OIL WAS LEAKING FROM THE ENGINE COMPARTMENT. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER FOR DIAGNOSIS. THE ENGINE OIL COOLER AND ENGINE COVER WERE BOTH REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE PROBLEM. THE FAILURE MILEAGE WAS UNAVAILABLE. ...UPDATED 04-22-14 *BF THE CONSUMER STATED THE TIMING CHAIN AND VVT ACTUATOR WAS A RECALL ITEM. THE VEHICLE HAD NOT BEEN REPAIRED. UPDATED 04/28/2014 *JS

I WAS DRIVING AT ABOUT 25MPH WHEN I NOTICED A BURNING SMELL. I PULLED OVER AND POPPED THE HOOD AND SAW SMOKE COMING FROM THE AC COMPRESSOR. IT TURNS OUT THAT THIS IS COMMON FOR THIS MODEL. MAZDA EXTENDED THE WARRANTY BUT OF COURSE MINE EXPIRED THIS YEAR. IT'S JUST A SHAME THAT MY CAR HAS LESS THEN 40K MILES AND MAZDA HAS ACKNOWLEDGED THIS IS AN INFERIOR PART, BUT WONT HELP COVER THE COST. THERE ARE HUNDREDS OF REPORTS OF THIS PART FAILING AND BREAKING THE SERPENTINE BELT CAUSING THE CAR TO LOSE ALL POWER. THIS SHOULD ABSOLUTELY BE A RECALL. IMAGINE THIS HAPPENING WHILE ON A HIGHWAY OR TURNING AT AN INTERSECTION. *TR

MAZDA GOT STUCK AND HAD NO POWER THE FIRST TIME SECOND TIME HAPPENED OCTOBER 9,2013 CAR KEPT SHUTTING OFF AND FINALLY COULD NOT MOVE. TURBO ONCE AGAIN TWICE IN 5 MONTHS AND I ONLY HAD THIS PRE-OWNED VEHICLE FOR 7 MONTHS. *TR

THE OIL COOLER ABOVE THE FILTER IS LEAKING VERY BAD, AND I NEED TO REPLACE THE GASKET,BUT I HAD NO PRIOR LEAKS BEFORE AND IT WAS HARD TO START MY VEHICLE. YOU CAN'T JUST BUY THE GASKET FOR THE COOLER, UNLESS IT'S THE NEWER SILVER OIL COOLER, THE PART ALONE IS AT LEAST $400, BUT THERE SEEMS TO A FREQUENT ISSUE OF THIS WITH MANY OTHERS, ON THE 2008 MAZDA CX-7. *TR

TIMING CHAIN WENT OUT . MAZDA IS TRYING TO SAY IT SLUDGE FROM POOR MAINTENANCE . EVEN THOUGH WE HAVE ALL RECEIPTS SINCE WE OWNED IT FOR OIL CHANGES. WE JUST PURCHASE THIS CX7 IN AUGUST OF 2012 WITH ALMOST 28000 MILES. NOW A YEAR LATER AND 40000 MILES IT NEEDS A MOTOR. *TR
