Rather than suggesting a different manufacturer, I’d suggest getting a complete machine swap under whatever lemon law is applicable in your location. Obviously 3 repairs in 10 months is unacceptable, but Apple’s machines – even including the keyboard faults – aren’t generally that unreliable.
I picked up a maxed out 2016 MPB right when it came out, including 2 LG 5K displays. I suffered random total system crashes with those external displays connected.
After going through three repair cycles Apple replaced mine with a brand new (faster) 2018 model, I didn't even have to ask for it. It was a bit of a drag to backup/restore the machine a bunch of times but Apple's service was top notch.
If it is the keyboard then it’s 4 years, not 3 (https://support.apple.com/keyboard-service-program-for-mac-n...).
