I wouldn't put a lot on that part number change. IIRC, the 20-21 had a cooling duct and heat insulation around the QS and 22+ that configuration was revised. They dropped the heat insulation on the QS and changed the air duct and added more cooling vents in the lower fairing.
Interesting that the 2025 dropped this QS style all together. Instead it uses input from the gear position sensor to determine when the rider is making an up or down shift. The gear sensors have suffered heat problems before, so it's unknown if this new strategy will be problematic or not.
At its core, it's still the same Domino +5v QS. There's a test you can do with the dealer tool to see if the QS is sending the right voltage to the ECU at rest, when upshifting and downshifting. The dealer will likely do this, and test ride the bike. If they can't duplicate it, nothing will get done. Maybe if you had a video of it causing problems you could advance a claim.
