I would imagine that there were manufacturers working on their own scan tools now for Tesla's as well as the Ford EV mustang.

Probably your mechanics were keeping up with the latest and the newest or you had a gremlin in your car that was only happening every other time you went over a bump? In any event it's always interesting to hear the other side of the coin
