We're on a trip right now to Vermont. My wife was driving and right around the 3hr mark she disabled autosteer to get around a semi. Immediatley after that maneuver, the gray steering icon went away and kept saying "Autosteer temporarily unavailable." TACC continued to work. Figuring she just missed the alerts (although I thought TACC would disable too), we kept going and supercharged shortly after. I took the next leg, AGAIN, 3:10hrs into my ride about 20min before our next charge, I disable to pull around a slow car and boom, same thing. Can't turn autosteer back on and get "Autosteer temporarily unavailable." Both times we were on the same interstate that we had been on for at least 20min prior using autosteer the entire time. Any ideas? Both times after putting the car in park, steering came back.
