NHTSA Complaint #11416085 — 2017 CADILLAC XT5

I BOUGHT THIS CADILLAC 2017 XT-5 USED WITH 4,000 ON IT IT HAS 11,000 ON IT KNOW. I TOOK THE VEHICLE IN FOR TIRE ROTATION & OIL CHANGE. THE SERVICE MANAGER TOLD ME THAT THESE TIRES MICHELIN PREMIER LTX 235/65 R 18 TIRES ON THIS YEAR 2017 ARE BAD TIRES. THE TREAD ON THE TIRE WAS MEASURED . 5/32NDS AT 11,000 MILES THESE TIRES ARE WARRANTYED TO 40,000 MILES. THEY SAY YOU SHOULD REPLACE YOUR TIRES IF THE TREAD TREAD IS 4/32NDS OR LESS! I THINK THAT WILL HAPEN IN THE NEXT 5,000 WHEN I GO IN FOR MY NEXT OIL CHANGE. I THINK I SHOULD HAVE THESE TIRES REPLACED FOR NO CHARGE AT ALL. THE DEALER SAID WHEN I COME IN AT 16,000 MILES FOR MY OIL CHANGE HE SAID HE WILL REPLACE THE BAD TIRE WITH NEW ONES THAT COST $205. HE SAID HE'D PRO RATE THE TIRES & HE SAID THE WILL CHARGE ME $450 FOR THEM. IF THESE TIRES ARE DEFECTED , WHY SHOULD I PAY ANY MONEY TO REPLACE THEM, IF THEY MANUFACTURED THE TIRES WRONG ??? VERY DISAPPOINTED IN THE TIRES. I HAVE BOUGHT MICHELIN TIRES FOR AT LEAST 4 VEHICLES , IN PAST YEAR'S,AND NEVER HAD A PROBLEM WITH THE TIRES!!
