2008 Mazda CX-7

AS I WAS DRIVING MY MAZDA ( WITH A TURBO ENGINE) ALONG THE HIGHWAY IT BEGAN TO DECELERATE ON ITS OWN AND MAKING A LOUD KNOCKING/GRINDING NOISE. IT STOPPED ON THE ROAD GOING UP A HILL WITH NO TURNOUTS. SO IT APPEARS THAT THE TURBO BLEW UP. IT WILL START, BUT I CANNOT GO ANYWHERE. I HAVE ALSO HAD TO REPLACE GASKETS ON MY OIL FILTER HOUSING UNIT, AS THE STOCK GASKETS WERE FAULTY AND CAUSING A SEVERE OIL LEAK. ALSO, MY EMISSIONS REGULATION ( EGR) VALVE IS BAD AND THEREFORE WILL NOT PASS SMOG. EACH OF THESE ISSUES I AM SEEING MORE AND MORE COMPLAINTS ABOUT FROM OTHER OWNERS OF THE SAME VEHICLE. MAZDA HAS MADE A HORRIBLY DEFECTIVE CAR AND REFUSES TO DO ANYTHING ABOUT IT EXCEPT TO CLAIM OWNER NEGLIGENCE. I BOUGHT MY CAR WITH 40K MILES ON IT AND IT HAS BEEN FALLING APART FROM THE START. THERE IS ABSOLUTELY NO EXCUSE AND THIS IS NOT OWNER NEGLIGENCE, IT IS MAZDA NEGLIGENCE AND REFUSAL TO MAKE ANYTHING RIGHT ON THEIR COMPLETELY DEFECTIVE VEHICLES. *TR

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.

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

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

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
