I have owned my Pixelbook Go for 29 months - no warranty.  Nice, light weight, backlit keyboard is great.  HOWEVER, about five months ago the camera stopped working.  Tried all the on-line fixes, no use - sigh.  This month the touchscreen stopped working, so I again tried all the appropriate on-line fixes.  In frustration I took it to a Google approved repair group (Asurion backed).  Guess what - the Pixelbook does not allow you or a third party to repair it.  Now I will look for a new computer that does have a right-to-repair in case it ever needs it.
