What owners wrote

The car locked my toddler inside his car seat because the 12v battery died died as soon as we put him in his seat and closed hid door. There was absolutely no warning before that battery had died, indicating that it was low. Because of the way a Model Y is designed, there is no mechanical way to open the door when the 12V battery dies. The toddler is incapable of manually unlocking the door from inside when the electrical button doesn’t work.
