Rear passenger door intermittently won't latch?

We've had it happen once. The rear passenger door accidentally got slammed pretty hard and bounced back before the electronics could latch the bar. We were able to close it after a few seconds when it reset itself.....no big deal. Not sure why it took so long for yours to reset.....

 

Maybe time to remind some people that they should buy their own Gen 5 Prius if they want to slam doors. Other option is not viable: removing doors so they can't be slammed.

 

When they got out, they may have accidentally (or a strap of a back pack) hit the safety lever on the door frame. Had same thing happen myself and toggles it.. solved

And it's possible you may have accidentally put it back into place (if this was even the problem) while trying to figure it out.

Looks like a black small lever lt pin that has maybe and inch or half inch of play to move into two settings, or maybe it resets a setting. I forget.

But had same exact experience of door mysteriously not shutting after getting out of rear. Fixed when I played with the lever a bit, like a monkey.
