Valve (United Radio) just approved me for a replacement Steam Deck due to L1 being unreliable and stiff (I think its broken but I didn't want to crack it open since it was under warranty). This was due to them thinking that either repairs will take too long or other factors (my guess is that the button boards are not in stock and its faster to just send me a replacement Steam Deck). Valve appears to be out of retail refurb Steam Decks, so unless they reserved some refurbs for RMA replacements, I really hope I get a brand new one.
