I've had my Bike+ about 14 months.
Having similar screen issues others have noted here in this thread. I don't recall a recent software update, but I noticed the screen coming on by itself, also was unresponsive to touch, until rebooted. The bike worked fine after a reboot but slowly exhibited touch screen issues over time.
My issue was the very top 1/4 inch and bottom 1/4 inch (where all the menus are) was unresponsive, but the center of the screen was fine. I was able to go into the settings and enlarge the screen, which made the bottom menu large enough to be in the working part of the screen, but the enlarged view was obnoxious. I contacted tech support, we reset the bike, factory reset, etc... nothing worked.
Of course I am at 990 rides, and 2 months out of warranty. :/
I broke down and purchased a replacement screen, I figure I use the bike enough to justify the $650 expense. Ouch!
So I have the replacement screen installed now and it works fine. Yay.
What the heck do I do with my non-working screen now?
Is there somewhere that will refurb it so I can sell it?
