All of my intermittent "won't start" problems are gone since having the starter replaced under extended warranty. Dealer never did experience the problem as it would only occur after sitting for several days to weeks. Kept a log and video recorded the start attempt each time. Finally captured a no start with audio and full view if the dash lights.
Tech finally agreed and it was written up as a starter problem, which extended warranty then helped with.
