I have the same issue with the high beam switch. The new type of switch gear seems to be fragile. I also noticed that a few of the other buttons feel stiff after the bike has been wet.
This is probably a generic issue with the type of switch they use. Not sure it will be better with a new set of switches. I guess BMW will need to change the design if they end up replacing enough though.
