    Our repair shop has recently had issue with 04 quest burning out ign coils after 2 days of driving with replacement of all 6 coils. Thought we had defective coils so we replaced again, 2 days later same problem. Found ground cable from battery was completely broken off where it mounts to the transmission under the battery tray, resulting the eng to ground through the coil grounds burning them out. Replacing rear three coils 3 times was a tremendous loss but root problem was found. New ground cable fixed our problem.
