TL* THE CONTACT OWNS A 2008 MAZDA CX-7. THE CONTACT STATED THAT WHILE DRIVING 20 MPH, THE VEHICLE MADE A POPPING SOUND AND WHITE SMOKE EMITTED FROM THE REAR OF THE VEHICLE. THE CONTACT MENTIONED THAT THE VEHICLE STALLED IMMEDIATELY AFTER. THE VEHICLE WAS TAKEN TO THE DEALER. THE TECHNICIAN DIAGNOSED THAT THERE WAS HOLE IN THE PISTON CAUSED BY THE TURBO CHARGER. AS A RESULT, THE ENGINE NEEDED TO BE REPLACED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE VIN WAS NOT AVAILABLE. THE FAILURE AND CURRENT MILEAGE WAS 78,000.

EGR VALVE FAILURE ON A 2008 MAZDA CX-7 WITH 47,500 MILES. I HAD NEVER HEARD OF A EGR VALVE BEFORE MY CHECK ENGINE LIGHT CAME ON AND I TOOK IT TO THE LOCAL AUTO PARTS STORE TO HAVE THEM TELL ME THE ERROR CODE. TOOK IT TO THE DEALERSHIP AND THEY TOLD ME THAT THE WARRANTY FOR THE PART WAS 60MONTHS/60,000 MILES. WHILE I WAS WAY UNDER ON THE MILES, I WAS 5 MONTHS OVER ON THE TIME. SINCE THIS WAS MY 3RD TRIP INTO THE DEALERSHIP OVER THE PAST 5 MONTHS DEALING WITH PROBLEMS/MAINTENANCE WITH MY CX-7, I ASKED WHY THIS PARTICULAR PART FAILED. I WAS TOLD THAT IT WAS DUE TO THE NEGATIVE EFFECTS OF ETHANOL. AFTER SOME QUICK RESEARCH, IT IS CLEAR THAT 2007-2008 MAZDA CX-7 HAS SERIOUS PROBLEMS WITH THE EGR VALVE. IT WILL COST ME $650 TO FIX. MAZDA SHOULD HAVE BEEN FORCED TO RECALL THIS PART SINCE IT LOOKS LIKE IT WAS DEFECTIVE FROM THE START. WAS TOLD THAT A NEW REPLACEMENT PART FOR THE EGR VALVE WOULD BE PUT INTO THE VEHICLE WHICH WILL NOT BREAK DUE TO PRESENCE OF ETHANOL IN GAS. *TR

THE GASKET ON THE OIL COOLERS ON THESE CARS ARE DEFECTIVE. I HAVE AN OIL LEAK FROM THIS GASKET THAT PUTS ME AT RISK FOR AN ENGINE BLOWOUT. I WILL HAVE TO REPLACE THE ENTIRE OIL COOLER AT A COST OF $500+ BECAUSE THE GASKET CAN'T BE PURCHASED SEPARATELY. MAZDA NEEDS TO TAKE RESPONSIBILITY FOR THIS BEFORE PEOPLE GET STRANDED ON THE ROAD. IF YOU SEARCH THIS OIL LEAK ONLINE, YOU FIND DOZENS OF POSTS ABOUT THIS HAPPENING TO OTHER CX-7 OWNERS. THIS IS A CROSSOVER SUV GEARED TOWARDS FAMILIES. I DRIVE MY KIDS AROUND IN IT AND NOW AM VERY CONCERNED ABOUT THE SAFETY OF THIS CAR. *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
