I think I had a FUJI or somesuch, but it's in the Ford 3000 tractor now as I kept the Optima Yellow Top from my Trooper RS and swapped it as soon as I got home from the dealership with the VX. I know of a few people who had similar problems with OEM batteries in several new Toyotas as well. Kathy's '01 Trooper's OEM battery just went kaput at about 23K miles recently and got a Red Top replacement. Not a lick o' trouble since!
