Hello, just purchased my new Yamaha N3X a couple of months ago. Great sound, but having intermittent problems with some of the keys. One key is particularly problematic G#-5. I made a little video to demonstrate. I could play that note by itself all day and I don't think it would fail. But play some notes around it, especially slowly and legato, and it fails often. When it fails you get no sound and you can feel that the key does not descend all the way to the bottom of the keybed. The next time you press it it will work. Never seems to fail twice in a row. Got to be an action issue, right? (Although I don't understand why it doesn't fail when you only play that G# and no other notes). I don't know a lot about the action on grands - suspecting the backcheck or some kind of repetition lever problem. Hoping someone here with grand piano action expertise can look at the video and identify the culprit. I would like to have a more informed opinion before I call the Yamaha tech people.

Sounds like hammers or whippens rubbing against each other. It’s a simple regulation with slightly untightening the screw, centering the hammer/whippen and then tightening back. You can do it yourself but if you don’t feel comfortable, ask a piano technician. Happens also on acoustic grands.

P.S. watched the video. Probably not rubbing but some other regulation issue.
