MacBook Pro (15-inch, 2016) . I am having the same set of issues with my laptop keyboard sticking and battery draining fast. I called Apple support and took it to my local support store and still no help. They waited till my warranty as ended to tell me my warranty is Up. I am so Pissed off at APPLE...
The MacBook Pro seems to have this problem much more than the MacBook.....head over the MacBook Pro Forum to find much more keyboard discussion.
