When to replace a seat before it expires

After a moderate or severe crash. NHTSA lists the conditions under which a seat can stay in use after a minor one: car seat use after a crash.
When the label with the date of manufacture is missing and the maker cannot tell you the date from the serial number.
When the seat has a recall that has not been fixed. Register the seat with its maker so recall notices reach you.
When your child is past the seat's height or weight limit, whatever the date.

Before you throw an expired seat out, cut the harness straps and write EXPIRED on the shell so nobody picks it up and uses it.
