I've been holding off replying but will speak up now.
I've been on the forum on and off for over a decade.
My 50e is a week 44 build from '23 that now has 4040 miles that are probably 75% ICE, 25% all electric.
I had one CEL for a code P0CEF. I believe that is a CCU temperature sensor that is considered out-of-range. It came up the morning after sitting out and charging some during -16F temps. I talked with the dealer who was very responsive but circumstances didn't allow me to bring it in. After a week of 100% normal performance (including a 600 mile trip) the CEL light turned off on its own. The car has not been back to the dealer since delivery.
I also had one episode of glitchy iDrive behavior but a system reset resolved it 100%. Link to method ->
