Warranty service with Specialized is a PITA. First, dealers that sell Specialized bikes may or may not be Specialized dealers, so the first problem is finding a Specialized dealer who does service work. Second, before a dealer will do any work, you have to provide proof of purchase, which means a copy of the sales receipt. The Specialized app that shows the serial #, date of purchase and registration to you for your $3,500+ bike is not good enough for Specialized. You have to produce a sales receipt. Best practice is to take picture of the receipt and keep it on your phone, 'cause without it, you can't get any work done. Third, wait in a que for service/diagnostics, then wait again, even longer, for parts to be shipped from Specialized.
