NHTSA Complaint #10631440 — 2010 MAZDA CX-7

ON 8/31/14 I NOTICED A RATTLING NOISE WHEN I ACCELERATED AS WELL AS A WHINING NOISE. THE NOISE WAS INTERMITTENT AND DID NOT OCCUR ALL THE TIME, BUT WAS A DISTINCT NOISE COMING FROM UNDERNEATH THE VEHICLE. I HAD NOT HAD ANY CHECK ENGINE LIGHTS ILLUMINATED OR ANY OTHER WARNING LIGHTS. I BROUGHT MY VEHICLE INTO MY LOCAL MAZDA DEALERSHIP AND THEY ADVISED IT WAS THE TURBO AND IN ORDER ACCESS APPROPRIATELY THEY WOULD NEED TO TEAR DOWN THE ENGINE. AFTER READING ONLINE THERE ARE NUMEROUS DOCUMENTED ISSUES WITH TURBOS, VVT TIMING CHAINS AND ENGINE ISSUES WITH MAZDA CX7. THE SHOP CALLED ME BACK 2 DAYS AFTER I DROPPED IT OFF AND SAID I WOULD NEED TO REPLACE THE TURBO & I NEED A NEW ENGINE. THEY ALSO STATED SINCE THERE WAS OIL SLUDGE PRESENT THAT I WOULD BE RESPONSIBLE FOR $9000 COSTS. I PROVIDED THE DEALERSHIP MY OIL CHANGE RECEIPTS INCLUDING THE LAST OIL CHANGE THAT WAS DONE IN JUNE. MY CAR WAS STILL WITHIN 3000 MILES AND WAS NOT DUE A OIL CHANGE, HOWEVER THE OWNERS MANUAL STIPULATES RECOMMENDED CHANGES EVERY 7000 MILES!! THE DEALERSHIP ADVISED THAT WHEN I BROUGHT IT IN NO OIL WAS IN THE DIPSTICK AND BECAUSE THERE WAS SLUDGE MAZDA IS DENYING MY POWERTRAIN WARRANTY (WHICH IS STILL ACTIVE) DUE TO NOT MAINTAINING THE VEHICLE. THIS IS ABSURD, I HAVE MAINTAINED MY VEHICLE AND MAZDA IS USING THIS AS AN EXCUSE TO NOT BE RESPONSIBLE FOR A OBVIOUS DEFECT IN THEIR VEHICLE!!! THERE ARE MANY DOCUMENTED INSTANCES ABOUT THIS SAME SCENARIO HAPPENING WITH OTHERS ALL OVER THE INTERNET, THIS ISSUE IS A RESULT OF A DEFECTIVE TURBO AND NOT DUE TO LACK OF MAINTENANCE. MAZDA EXTENDED TURBOS AND VVT TIMING CHAIN ISSUES TO 7 YEARS BECAUSE OF THIS SAME SCENARIO FOR 2007-2010 MAZDA CX7S BUT WHEN I ASKED ABOUT SSP 86 IM BEING TOLD MY VEHICLE DOES NOT QUALIFY. I WOULD LIKE TO KNOW WHY MAZDA CAN GET AWAY WITH NOT ABIDING TO THEIR WARRANTY AND REQUEST THIS BE INVESTIGATED. THANK YOU *TR
