yup...some cars "accelerator by wire" went to TOGA uncommanded when moisture had penetrated somewhere when it shouldn't have...like the AOA vane shaft seal failing and moisture entering the mechanism and freezing, thus failing the AOA vane on position,,,wreaking havoc.on the 320 anyway...full back stick, no help..requires QUICKLY reaching overhead and switching off ADR 1&2 before control can be regained...there are many benefits to FBW, and of course, some pitfalls as well...usually discovered by some poor crew in less than ideal weather conditions...
