if its not too far gone it could be gummed up with crud, often a good cleaning and relube with light oil or mineral oil can allow pawls to engage fully again. Also call your Giant dealer to see what they know, suggest. there may be some info to steer you in right direction.

My P-AM2 freehub exploded. I mean, it spins when I apply real torque to it. Does anyone have photos of the freehub-pawl mechanism? I won't have time to dismount it for a week but would like to have an idea if it is repairable or not, or buy parts in advance.
Well I had a closer look and it turns out the freehub is OK and I was spinning the chain over the very worn-out aluminium range extender cog. The rest of the cassette looks mint so I will just throw a new 42t cog there and carry on smashing my current wheels. I will let you know in case I want to get an extra set of those P-AM2 anyway, thanks!
