Interior lights staying on

[Jabberwocky]

Hello. I have a 2018 Mazda 3. 2 days ago, the interior lights started staying on. I've flipped the on/off/door switch to every combination. I've rechecked every door and trunk. The lights will only turn off if the car is off and locked. They are on when driving which kind of sucks at night. Any ideas?

I think there is a body control unit. maybe there is a problem there. .
Even if you leave a door ajar, the lights will eventually turn off (about 20 mintues).
If you lock the car do the lights 'fade' in the normal way?
