NHTSA Complaint #11030859 — 2007 MAZDA CX-7

WHEN DRIVING THERE IS A RATTLING NOISE THAT SOUNDS LIKE SOMETHING IS LOOSE. WAS TOLD FROM MAZDA SERVICE DEPT. THAT IT WAS VVT (VARIABLE VALVE TIMING) ITS A CHAIN WHICH IS - THE PROCESS OF ALTERING THE TIMING OF A VALVE LIFT EVENT, AND IS OFTEN USED TO IMPROVE PERFORMANCE, FUEL ECONOMY OR EMISSIONS. IT IS INCREASINGLY BEING USED IN COMBINATION WITH VARIABLE VALVE LIFT SYSTEMS. I WAS TOLD THAT MOST MAZDA CARS ARE HAVING THIS PROBLEM AFTER MILES OF DRIVING AND THE COST OF REPAIRS IS ALMOST $2000. MAZDA ISN'T TRYING TO COVER THE REPAIR WHICH IS SHOWING TO BE HAPPENING ON ALMOST ALL OF THEIR SUVS.
