Carbon crank with loose pedal thread
The FSA Warranty is 2 years on cranksets.

I would still contact them to see what they recommend.They might be able to repair, recommend a company who can repair or offer you a lower-cost replacement. You didn't say which crank arm it is but they may also be able to provide a replacement for just that crank arm.

I would also stop using the crank for now for two different reasons:


In the event this is repairable, you don't want to make the current damage any worse as it could tip things past the point to where it is no longer fixable.
You don't want to risk catastrophic failure of the crank where the threaded insert breaks completely out of the crank taking the pedal and your control of the bike with it.
