Have had vehicle into dealer many times over the years complaining of no start issue. Once vehicle is jumped it is fine for awhile. Battery, starter and alternator always seem to test good and no codes are found. I had to go buy a portable jumper unit to carry as this happens at least once a week and if it sits more than a few days, it will not start and is dead. Dealer states they cannot find the cause. Bought new in 2005 and has happened over 35 times since new.
