I doubt it, this is a different model.
And so far it is a one off sporadic failure. It hasn't yet been examined for defects or other obvious causes, but I doubt it will be a fatigue failure this early on. It may be a casting defect or the part may have been mistreated in some way, either as part of the bike (the owner says no), in the assembly process or in the manufacturing of the part.
If the cause cannot be determined and the failure rate is extremely low, then there is no point doing a recall, since there you do not know what you are trying to fix.
I expect that unless we see a rash of similar failures, this will reach a similar conclusion to the report quoted above.
