My 2018 Model 3 failed inspection for a worn left rear control arm in NH. Tesla has canceled my appointment 2X since June and have pushed me out into late August because they can't seem to get the replacement part. I am wondering if this is a problem others are seeing (not the horrendous service, and lack of communication or spare part mystery) but surprised with about 70K miles that this can wear out enough to fail a state safety inspection. Meanwhile, hoping I don't get a ticket, and I don't lose control of the car.....
