2010 MAZDA CX-7 Power Train Problems

TCS AND CHECK ENGINE LIGHT IS ON. THE CAR DOES NOT HAVE POWER EVEN IF THE GAS PEDAL IS PRESSED ALL THE WAY, THE CAR MOVES ONLY UP TO 5 MILES PER HOUR (RPM POWER). VEHICLE LOSES THROTTLE. AC BLOWS WARM WHEN TCS LIGHT IS ON. THERE IS A WHITE SMOKE FROM THE EXHAUST. THIS USUALLY HAPPENS AFTER THE CAR IS PARKED FOR COUPLE HOURS. THE SAME ISSUE OCCURS SEVERAL TIMES WITHIN A PERIOD OF YEAR AND A HALF. MY CAR WAS @ SERVICE SHOP MORE THAN 2 MONTHS. I CONTACTED MAZDA CORPORATE OFFICE IN SEVERAL OCCASIONS AND THEY ARE AWARE OF THE ISSUES I HAVE WITH THE CAR, BUT THEY DID NOT RESPOND POSITIVELY.

WAS DRIVING AND ALL OF A SUDDEN LOST POWER AND A HOWLING NOISE NO CHECK ENGINE LIGHT CAME ON. PULLED OVER TO SEE WHAT IT WAS AND NOTHING VISIBLE NO LEAKS NOTHING. HAD MY WIFE HIT THE HAS AND NO NOISE. STARED DRIVING AND NOISE CAME BACK AND WHITE SMOKE. JUST HAD AN OIL CHANGE DONE AND NEXT OIL CHANGE DUE IN ABOUT 1000 MILES. DROVE ABOUT 20 MPH TO GET HOME CHECK OIL AND IT WAS OK. THE WHITE SMOKE MAKES ME THINK THE TURBO WENT ON MY CAR. I JUST PURCHASED THIS CAR IN OCTOBER OF 2015. IT'S BEEN BACK TO THE SHOP FOR ELECTRIC PROBLEMS WITH THE KEY AND RADIO THAT STILL NOT RESOLVED. RADIO SHUTS OFF AND BEEPS THAT KEY IS NOT IN CAR.

2010 CX7 GRAND TOURING WAS PURCHASED WITH 5,844 MILES FROM DEALER. WE CHANGED THE OIL & FILTER EVERY 6,000 MILES USING RECOMMENDED OIL AS SHOWN IN THE OWNERS MANUAL (5W20). MANUAL RECOMMENDATION IS TO CHANGE OIL EVERY 7,500 MILES WITH NORMAL DRIVING CONDITIONS WHICH IS THE CASE AS MY WIFE DROVE TO AND FROM WORK. AT 37,000 MILES, VEHICLE WAS STARTED IN 20DEG F. TEMPS, WARMED UP FOR AND EXPERIENCED LOUD ENGINE KNOCK. ONCE DRIVEN, VEHICLE HAD NO POWER AND HAD TROUBLES GETTING TO HWY SPEED. DROVE THE VEHICLE TO THE DEALER WHERE WE PURCHASED IT THE NEXT DAY AND WAS INFORMED THE ENGINE HAD EXCESSIVE ENGINE OIL SLUDGE UNDER THE OIL FILLER CAP. SERVICE DEPT. CALLED ME THE NEXT DAY AND SAID THEY WOULD NEED TO PULL THE VALVE COVER TO INVESTIGATE FURTHER TO SEE IF MAZDA NATIONAL WOULD COVER UNDER WARRANTY. WE AGREED SINCE WE PROPERLY MAINTAINED THE...

ON OCTOBER 4 2012 I WAS TOLD BY THE MAZDA DEALER SERVICE DEPT THAT MY TIMING CHAIN AND TURBO CHARGER ON MY 2010 MAZDA CX7 WENT BAD AND NEEDED TO BE REPLACED. MY VEHICLE ONLY HAS 39400 MILES ON IT AND SHOULD BE COVERED UNDER MAZDAS POWER TRAIN WARRANTY. I WAS TOLD BY MAZDA WARRANTY DEPARTMENT THAT THEY WOULD NOT PAY FOR ANYTHING BASED ON SLUDGE BUILD UP IN THE ENGINE. I SENT THEM COPIES OF OIL CHANGE MAINTENANCE AS THEY REQUESTED WHICH WERE DONE AT APROX EVERY 3400 MILES AS OPPOSED TO THE REQUIRED 7500MILES. I WAS TOLD THEN THAT THEY WOULD COVER ONLY THE TIMING CHAIN REPLACEMENT BECAUSE IT WAS ON A RECALL AND THAT THE TURBO CHARGER WOULD NOT BE COVERED AT ALL. THEY CAME TO THIS CONCLUSION DUE TO THE TURBO GOING BAD DUE TO AN OUTSIDE INFLUENCE WHAT IS THAT I ASKED AND THEY HAD...
