I don't think I am alone in having problems with BMW's handlebar switchgear. In my case the cruise control has failed to work correctly for the THIRD time, which requires the entire left switchgear assembly to be replaced.
Why does BMW refuse to redesign this problematic item? Each time it is replaced with the exactly the same part, which will inevitably fail again. The cost to BMW for warranty claims must be quite considerable plus it gives them a bad name regarding reliability.
It would be interesting to know if anyone else has had more than three left switchgear assemblies replaced.
On my 2013 GS I had the very same switch-gear failure you describe and the dealer replaced it under warranty with an updated unit during the summer of 2013 and it worked fine, about two years later I had the bike in for a recall repair on the transmission seal and the dealer replaced the switch-gear on both sides as part of a customer experience improvement campaign and I have not had any issue's with them either.
But it is my understanding that the parts had been redesigned at least twice since the new model was introduced in 2013 and that the switches were originally manufactured by Nokia.
There is not always a part # change when parts are updated unless they change manufacturers of that part.
Same issues with my CC and the right side start/stop button is beginning to fail again. While it is an annoyance as long as they keep replacing them I'm good with that. I suspect we just have to burn through the inventory of unreliable ones before we get the good stuff.

ditto with JetSpeed re rain riding.
On my 16 the Trip/Info button gets a bit stiff and sticks sort of, but an occasional smidge of wd40 handles it. If I could get it out I'd file the edges where the switch is nearest the housing and I think that would solve the issue.
In the first 7k ish miles I thought the cruise control was acting up, though now think it was user error.
When I would try to resume my prev setting it would set at current speed. I think it seemed that way because the resume response takes a bit of time and it seems like it is setting current rather than resuming prev speed.
It is something I am watching though
I had a K16 with a switch failure but they replaced both w/o issue, circa 2015. I was told at the time they did redesign the switches with more robust circuitry; never had another problem. NO issues with cruise control on that bike or the GSA. Good luck.
I lost all instruments on left side handlebar yesterday on new 2016. Service closed today but this sounds like switch gear issue? So they've known about this, just like the pump I had to have replaced when all coolant poured out weep hole first 500 miles? Very annoyed!
Sadly when BMW have a problem with a part, instead of redesigning it they merely fit the same old rubbish part. Time after time!
I have had three left switchgear assemblies replaced in less than 30,000 miles. Each time the cruise control switch had failed. The quality of BMW's switchgear is comparable to the plastic toys found in Christmas crackers.
