What are these OnStar reported Recalls?

[ecanem]

Back in December, Onstar reported these 2 recalls in an email to me:
2014450 INSPECT AIR CONDITIONING REFRIGERANT WARNING LABEL-* EXPIRES W/BASE WARRANTY *, 2014300 SERVICE UPDATE - POWER LIFTGATE INOPERABLE - * EXPIRES WITH BASE WARRANTY *.

I can't find anything about them anywhere. Does anyone know what they are? None of the dealers around me offer loaners so I don't want to waste my time with them if something isn't really needed.

Not sure why this was moved to Audio and electronics. Not related to that at all.
