I think it was because the BB was loosens over time, because it didn't came with lockring to hold the BB
I think this is one of the reason fsa carbon crankset is not popular
I did some digging just to make sure there wasn't a safety issue and from what I could find there was a design flaw in the original FSA carbon cranks. The crank arm was carbon and the spider was alloy. This junction could loosen over time especially when used on the street for "skidding". Since there are multiple options for BB I don't see how that could be related to the crankset itself.
The new design is all one piece of carbon fiber and based on what I read it is a solid crankset. I run FSA on my cross bike also and have never had any problems.
