If you take your newly bought car in for service my advice is not to purchase anything outside what is covered. You are better off finding somewhere else. I bought two brand new tires and less than two months later received a nail that is non repairable in one of my tires. This service department does disclose there is no coverage on their tires outside a manufacture defect. I'm out 200.00 plus and will have to buy a new tire. I will never use Courtesy Chevrolet service again.
