NHTSA Complaint #10807974 — 2015 MAZDA CX-9

I PURCHASED THE CAR NEW ON SEPTEMBER 18,2015. HAVING THE CAR FOR 3 MONTHS I HAVE BEEN AT THE SERVICE DEPARTMENT 3 TIMES. I GOT HOME THE FIRST DAY AND THE BELT WAS NOT REGISTERING AND WAS MAKING NOISE WHEN I HAD IT ON. THE LAST 2 TIMES I CONTINUE TO HEAR NOISE COMING FROM THE CAR. THE NOISE IS HEARD FROM UNDERNEATH AND IT HAS TO BE DRIVEN FOR SIGNIFICANT AMOUNT OF MINUTES BEFORE THE NOISE GOES AWAY. I RECORDED THE NOISE ON NOVEMBER 28,2015 AND CALLED THE DEALER VERY UPSET BECAUSE ITS A PROBLEM THAT'S NOT BEING ADDRESSED AND FIXED. I DROPPED THE CAR OFF ON MONDAY NOVEMBER 30,2015 AND WAS TOLD YESTERDAY DECEMBER 1,2015 THAT THEY DONT SEE THE PROBLEM.THIS IS A NEW CAR AND I NEVER TEST DRIVEN BEFORE BUYING. I NEED HELP. I HAVE THE RECORDING BUT I CANT ATTACH IT ON HERE.
