There is a coolant that's red in color. What color do you see in the coolant reserve tank? You need to find out what this is all about. A leaking freeze plug could fail and loose all the coolant quickly enough to leave you stranded.

Transmission or power steering leak can be monitored for a long time before major failure, usually.

Do a good cleaning and find the source of the leak.

None of the statements can be ruled out yet. Is the door lock system blocked off or still attached?
