Yep. I have a 2016 MacBook Pro that's had two top case replacements for bad keys. It's been a year since the last one, and that's because I am EXTREMELY careful with this one specifically around heat. I strongly believe that heat under the keys is the cause, and not dust. I never, ever let the CPU temp spike (using iStat menus to show the current temp and disabling Turbo Boost). I also never charge an external device like a phone or iPad using the USB-C ports to avoid creating heat. Lastly, this computer never, ever sits on any surface that isn't solid. No bed, no couch, no lap. I use a tray or something similar if it's not on a desk. If you heat the computer to the point that you feel that trademark snapping sound in the membranes of the keys, you are screwed. You might as well make the appointment right then since your keys will fail soon. I might just fail this one on purpose because I could use a new battery which you get with the keyboard switch. Oh, and my camera no longer works for some reason.
