Unfortunately poorly made components of any material can fail. However carbon is generally not an issue. As someone who has 4 carbon fiber forks and has commuted on them I would not replace them. Two of the fork are from Whisky Parts Co. One is ENVE and the other is Specialized and the Specialized fork is the oldest followed by the ENVE and have had a lot of miles on them under a heavier rider with no issue.
The carbon I would worry about is really old carbon and really cheap stuff from unknown sources but if properly laid up from a known source nothing to worry about.
