Rig vote, faulting complaint (7)
I believe the answer is:
vertigo
'complaint' is the definition.
(medical complaint)
'rig vote faulting' is the wordplay.
'faulting' is an anagram indicator (I've seen 'fault' mean this (a faulty spelling)).
'rig'+'vote'='rigvote'
'rigvote' is an anagram of 'VERTIGO'.
(Other definitions for vertigo that I've seen before include "Type of dizziness associated with fear of heights" , "Problem brought on by heights" , "Lightheadedness, dizziness" , "Whirling sensation when balance is disturbed" , "Dizziness due to disorder in sense of balance" .)
