One of my employees has a 2018 MBP and the keyboard started going insane in the last week (space bar randomly firing, keys not responding, etc.). We have Applecare and a business JointVenture account with Apple. She took the computer in to the local Apple store and they immediately said they would fix it without asking any questions at all (and gave us a loaner due to the JointVenture program). Easy, but annoying, and it does show that the keyboard problem is absolutely still around.
