"Posting as AC because I work as an Apple service tech during the day.
These systems are probably the worst computers Apple has ever produced. The failure rate on them is astoundingly bad- so bad in fact, that the shop I work for is thinking about getting out of the Apple repair business just because we can't adequately support our customers when servicing these machines. We want to, but our hands are completely tied. It's a crap shoot if we can even get new chassis in stock these days (the keyboard is riveted to the lower chassis, which also contains the non-removable battery pack and a few other components). More and more we've been having to send the entire machine into Apple for servicing, at which point they just send you back someone else's refurb (yes, really, this is becoming an extremely common occurrence when servicing any of their portables) and you get to go through the whole process again when that inevitably breaks.
We've been swamped with these machines to the point that it's been clogging up our service centre for other customers with different machines. On any given week, there's as few as 5 machines awaiting parts (or to be shipped to Apple) and as many as 12. It's usually the keyboard that fails- either one or more keys refuse to work properly, or in some cases we've seen the entire board go tits up and totally scramble the input of the keys (ie, C types Z, J becomes backspace, etc). Other failures include bad or cracked touch bars (don't ask me how these get shattered so often, people keep swearing that they opened up their system one day and it was cracked- I'm starting to think the glass is shattering under the thermal stress from being positioned near the hot end of the system) and logic board failures presumably due to overheated components (we can't perform board level service on these machines, but that hasn't stopped me from putting a few systems under a microscope and poking around- there's a few power related ICs that seem to love blowing up and killing the entire system).
All in all, I've never seen anything like it. Our owner is pissed off enough he's thinking about dropping Apple entirely and pushing our customers to convert. We do service PC laptops, but it's rare we see keyboard issues with those that can't be fixed in 15 minutes using a $30 replacement part. With the MBPs, it's a $900 CAD piece, and you can't just buy one from Apple- you have to go through GSX to requisition one and send back the old part after you've removed it (they REALLY don't want spare parts getting out onto the second hand market). But again, that's assuming they're even in stock. The last time I was able to order a lower chassis was three weeks ago, and we've had to ship in about two dozen systems since then (which won't come back for 1-2 weeks).
Anyways, if you want my professional opinion- stay away from these machines. They're defective by design and Apple is clearly buckling under the service load (we're seeing something similar with the iMac Pro as well). I don't know what the **** they're smoking over there these days, but it's nothing good. A keyboard should not be an integral part of a computer like this. It should be easily removable and serviced without having to scrap half the chassis in the process. Apple ****ed up big time here, and it's finally swinging around to bite them in the ass. They won't admit it though, it's more likely you'll see some reference to a vague repair program in a few months promising to fix "affected" machines (hint: they're all affected).
