    Had this 2015 Prius 4 four a couple months. Today, all of the interior lights, (the two in the front, plus the dome light) are all staying on.
    Any ideas? The switch in the back is in the middle. Messed with it. Didn't help.They are staying on, after locking doors and significant time lapse.

    Is there a switch or button that would do this?

    Thanks!

    Check, and reclose the hatch? Slam it shut pretty hard.

    Dash dimmer seems like what it'd be, but still staying on! Might need to swing by the dealer. Hope the car starts this morning!

    Thanks ya'll any more possible ideas? Two month old car, so maybe some malfunction? But that dimmer switch seems like what it would have been. I was sure that would work, but it didn't.

    Is there a switch in your front overhead console? It might be bumped to the "on" position instead of the "door" position or "off" position.

    Maybe one of the door switches failed, mimicking a "door open" condition?

    I would disconnect the negative cable to the 12 volt battery as soon as possible, by the way.

    Might I suggest this is normal? The courtesy lights stay on a few seconds after you close the doors. If you come close to the car then the lights come on. You may think the lights were left on the whole time but this is a feature to light the interior as you approach the car with the key fob.

    Try walking away from the car for a few minutes and come back without the fob and check.

    Switch in front roof console did it. I knew there were two switches on left and right for lights, but there is a slider switch in the middle too. Did the trick.

    I leave that mother completely off, all the time. I'd rather put up with a bit of darkness than the inevitable drained battery.
