If you have 2500 mi, you are probably okay. You may have an earlier production that used the correct thread lock. Ask your LBS to check with Specialized. The standard offer is to exchange for the Roval Pave, which is a downgrade. My LBS didn't think that was a good deal so they offered the Reynolds Shadow. I preferred the Roval, but got started thinking that a new Roval would be better than a a wheel that had given me problems.

The Fusee 25 is 200 g lighter, has different spokes and different hubs. It also comes with Titanium skewers, which probably have little impact.
