I've always liked your GMC trucks but mostly been a ford owner so this december I bought a 2014 GMC sierra 1500 with 98,000 miles... Really love the truck but then start by having problems.. First my passenger window wouldn't roll down all the way ..got that fixed..then my rear drivers door lock don't work..and the big one my AC condenser has a leak ($1500 fix)which supposedly is a common problem with this vehicle..which I'm just so dissatisfied..I would really appreciated to have these problems fix for free!!!
