Kids complained they got a shock from the stove.

I put a meter on it, a pan on the burner while turned on is 40 volts
above ground. The rest of the stove metal seems to be at ground.

The burners look in good shape but it's an old stove. Burners
normally have ceramic insulation, right? Is it time to replace them?

Any electric leak is likely to be more than 40 volts as the burners run on
240 volts. Normally people and children don't touch the pan especially when
the stove is on. The pan is metal, the stove is metal, it all should be the
same electrial potential. The stove is (or should be grounded) so that any
leak will trip the fuse or breaker. Probably as said earlier, static shock
from someone with rubber soled shoes/slippers jumping to the grounded stove.
