2015 Honda Accord Fhev

I PURCHASED A CERTIFIED USED HONDA 8/2018. I HAVE ALREADY HAD TO REPLACE THE BATTERY FOR NOT STARTING AND A POWER FAILURE IN THE MIDDLE OF A BUSY INTERSECTION WHERE CARS WE GOING 40 MILES PER HOUR. I TOOK IT TO THE DEALER 3 TIMES FOR THIS BATTERY FAILURE. THEY TOLD ME THE CAR PURCHASE WAS ALMOST A YEAR OLD AND BATTERIES WERE NOT COVERED. I HAVE HAD 3 OIL CHANGES AN HAVE PUT 11,000 MILES ON THE VEHICLE SINCE THE PURCHASE AT 34,000 MILES. DURING THE LAST OIL CHANDE THE TIRES WERE ROTATED ON 7/10/2019. I RETURNED BACK WITH THE CAR ON 7/11/2018 TO TELL THEM THE CAR WAS NOT ROLLING SMOOTHLY. I TOOK THE CAR TO DOBBS AND A SECOND TIRE MANUFACTURER AND THEY INFORMED ME THE ROTATED TIRES ON THE FRONT OF THE CAR WERE DRY ROTTED. I RETURNED IT TO THE DEALER WITH PAPERWORK FROM DOBBS THE DEALER INFORMED ME THAT THE TIRES WERE NOT COVERED UNDER WARRANTY. THEY SAID THE ONLY WAY THEY COULD RECTIFY THE PROBLEM WAS TO SELL ME NEW TIRES. I KNOW THE CAR IS USED BUT, IF IT WAS CERTAINLY CERTIFIED WHY WOULD I HAVE TO REPLACE STANDARD ITEMS WITH 60,000 MILE WARRANTIES SO SOON? ACCORDING TO MY DEALER NOTHING IS COVERED WHEN I MAKE A REQUEST REGARDING VEHICLE SERVICES.
