Looked for 3 yrs prior to buying, really wanted an Avalanche. Looked as if the leaks had been fixed. Bought a brand new one but the midgate leaks when I wash it - leaks both into the cab and the bed (on both sides of the midgate). Going back a 3rd time to the dealer. Seems like mine is a lemon, some leaks on prior years but thought the leak issue was addressed. Take a hose & check yours before you buy....HOPEFULLY they can fix it, as really do otherwise love it.
MIDGATE LEAKS with washing - into the passenger cab & bed. Gas mileage could be better - but acceptable if they can only fix my leak!!!
