Overfilled? IIRC, it should only be covering the top of the plates.

Sounds like it may be overcharging and boiling the water if it only happens when running?

Suggest to get the charging circuit checked asap, to eliminate it if nothing else.

I agree. Maintenance free batteries (like all modern ones) don't vent nor need topping up unless they are abused. Measure the voltage across the terminals at a fast idle. More than around 14.5 and you've got problems. If left, it could damage other parts of the electrical system too.

Whats the voltage at 3000rpm with most of the major electrical loads off?
