Well, I got one of the Rare instances - @Mike Martin
I just received my new PX-5S and when I removed the tape from the keys, several were out of position. I guess an issue with the hammers?
The dealer said they don't have one in stock to replace it and thought I might check into warranty repair? As you can imagine, I would prefer to swap it out for another one.
BTW, I am in NJ, near Freehold if that helps.
