2008 MAZDA CX-7 Engine And Engine Coolingengine Problems

MY CHECK ENGINE LIGHT HAS COME ON IN MY 2008 MAZDA CX-9. TOOK THE VEHICLE TO THE DEALER AND THEY ADVISED THE EGR VALVE HAS TO BE REPLACED DUE TO IT BEING WARN OUT. MAZDA STATES THIS PART DOES NOT FALL UNDER EMISSIONS WARRANTY. AFTER DOING SOME RESEARCH, THIS APPEARS TO BE A COMMON PROBLEM WITH MAZDA'S AND I DON'T FEEL I SHOULD BE PAYING $1200.00 TO FIX A VEHICLE THAT IS ONLY TWO YEARS OLD. MAZDA HAS BEEN NO HELP JUST TRYING EXTORT MONEY FROM CONSUMERS. *TR

2008 MAZDA CX 7 GRAND TOURING - PURCHASED PRE-OWNED VEHICLE FROM A CERTIFIED MAZDA DEALER IN OCTOBER 2008, HAD A LOUD ENGINE SOUND AND DEALER ADVISED THIS WAS "NORMAL", JUST BEFORE WARRANTY EXPIRATION FOUND THAT TRANSMISSION SEAL WAS BAD AND REPLACED THIS AS WELL AS THE RECALLED COMPRESSOR. NOW AT 64K AND NOISE IN ENGINE IS GETTING WORSE AND IT IS IN FACT THE TIMING CHAIN LAPPING. FOUND OUT THAT THIS IS A COMMON PROBLEM AND THAT SOME PEOPLE HAVE BEEN HAVING THE CHAIN BREAK LEAVING THEM STRANDED IN THE MIDDLE OF THE ROAD. ALSO FOUND THAT THE ENTIRE CASING AND THE TENSIONING BELT/MECHANISM IS FAILING. THIS IS A HUGE SAFETY CONCERN AND I AM SURPRISED THAT NO ONE HAS RECALLED THIS, IT IS A VERY COMMON PROBLEM IN THE 07 MODEL AS WELL. WILL REQUEST OLD PARTS BE KEPT. CURRENTLY BEING WORKED ON. *TR

THIS NARRATIVE IS ABOUT TOTAL ENGINE FAILURE IN A MAZDA CX-7 2008. THERE WERE NO INDICATIONS LEADING UP TO THE FAILURE. I GOT REGULAR OIL CHANGES WELL WITHIN THE MANUAL RECOMMENDED 5000-7500 MILES. ONE MORNING ON MY WAY TO WORK, THE CAR SIMPLY STOPPED ACCELERATING WHEN I HIT A SMALL HILL. THERE WAS NO CHECK ENGINE LIGHT, NO WARNING, NOTHING. I DROVE THE CAR IMMEDIATELY TO MAZDA SERVICE. AS I WAS DRIVING TO THE DEALERSHIP, THE CHECK ENGINE LIGHT DID IN FACT COME ON. UPON LOOKING INTO THE PROBLEM, THE DEALERSHIP LOOKED AT IT AN DETERMINED THAT THERE WAS SLUDGE IN THE ENGINE AND THAT THE ENGINE WAS DESTROYED. I HAD A WARRANTY YET MAZDA REFUSED TO COVER IT DUE TO "LACK OF MAINTENANCE" FROM OWNER. I WAS FORCED TO REPLACE THE ENGINE AND WAS TOLD IF I WENT THE ROUTE OF ANOTHER ENGINE FROM A DIFFERENT MECHANIC OR MANUFACTURER,...

I OWN A MAZDA 2008 CX7 SPORT - PURCHASED NEW ON 11/28/2007. I HAVE 62,500 MILES ON THE VEHICLE. IT WAS TOWED TO THE DEALER ON 6/22/2010 WITH LOUD WHINING NOISE AND LOSS OF POWER. DEALER SAID THE TURBO IS MALFUNCTIONED. OVER THE NEXT WEEK THE EXTENDED SERVICE COMPANY FOR MAZDA REQUESTED MAINTENANCE RECORDS. I HAD THE OIL CHANGED OUTSIDE OF THE DEALER SOME OF THE TIME. THEY LOOKED AT THIS AND DECLINED THE WARRANTY REPAIRS. I KEPT CALLING AND THEY AGREED TO SEND OUT AN INDEPENDENT ADJUSTER. HE NOTED A "SLUDGE" BUILD UP ON THE OIL RETURN HOSE BOLT TO THE TURBO. THEY DECLINED MY WARRANTY COVERAGE. I AM HAVING TO PAY $2500 TO REPAIR. I HAVE BEEN DOING RESEARCH ONLINE AND THIS VEHICLE IS HAVING NUMEROUS ISSUES WITH SLUDGE BUILDUP. THIS COMES FROM THE ENGINE RUNNING TO HOT AND BREAKING THE OIL DOWN TO CREATE BLOCKAGES THAT ULTIMATELY...
