Tire Sidewall Problems of GMC Acadia

After roughly 7000 miles of use the 235/55r20 102v goodyear assurance weatherready tire has a bulge in the sidewall. There are no scuffs or scars on the tire to indicate an impact caused the bulge, it appears there is some sort of separation within the layers of the sidewall. I asked a goodyear retailer to inspect the tire and they said it's automatically considered impact damage if the bulge is in the sidewall and goodyear would not warrant such damage even though there is no evidence such as cuts, scuffs or scars. The tire inflation is to manufacturer's specifications and the tire isn't loosing pressure. Dot 1m78aja5r purchased oct 22, 2023 date code 3622.
