are there any reasons why this would turn off automatically? Drove for 1.5 hrs and it turned off (button not illuminated green). Wouldn’t even turn on when I pressed the button. However, I went out an hour later and it worked again. Any ideas why it shut off in the first place? Thanks

Are you talking about the start/stop button? If so, it depends on the level of charge the battery has. If the battery is too low it will be disabled. Also, if the cabin temperature is too high it will disallow automatically in order for the AC compressor to be activated.

Sport, sport+, headlights, AC, lots of “loads” seem to disengage S/S.

If you change any of the drive modes then it turns itself back on

If your seatbelt is off, eco will disable also.
