'19 F3S won't manually down shift or select reverse - heat related maybe? Ideas?

[golfsferr]

Lately my 2019 F3S will not down shift manually or go into reverse sometimes. I'll ride later and it works perfectly. I took it to my dealer and of course they could not duplicate the issue. So I drove it home and it was fine, then yesterday it would not manually down shift again and I couldn't get it in reverse. So I took it to the dealer again today and of course it worked fine. I seem to notice this issue after I have been driving it awhile. Could it be a heat related problem? Any ideas would be welcome, thanks.

Your LHS (left-hand switch) is failing. Search is your friend.

Thanks for your reply. The dealer originally said it could be one of several things. The problem is duplicating it at dealer. I could tell them the switch is failing but they won't take my word for it. Will a failing switch show up on their computer diagnosis?

Plus 1...my 2020RT acted just like that....finally wouldn't shift at all...replaced it, problem fixed. The LH multi switch assembly is $500+ for the part. It's doable to DIY, but tedious.
