Giant recently announced that if ANY composite component of a 2019 or later Giant bike is damaged while riding (you crash, you crack a rim on a pothole, you break your bars etc) they will repair it or replace it free of charge. The specifics of the coverage seem comprehensive, Giant even covers racing. No other brand is matching this kind of offer right now.

Note that this coverage is in addition to the already existing lifetime warranty on their bikes that covers any manufacturing defects.
