Mom has a '18 Suburu Outback. Has an intermttent hesitatation the dealer cannot find. Every once in a while, like once a week, it will hesitate for about three to four seconds when she tries to go from a dead stop. Dealer says it shows no codes and they have not been able to replicate it. She drives with one foot as does her husband (he's a BTK amputee)


Any Ideas?
