2007 with 3,300 miles. Truck pulls to the left significantly while braking from 50mph on. I have had this truck to two different dealers 6 times. They are stumped. Two sets of brake pads and a tire rotation. Two ride-a-longs with the service manager who admits the truck pulls and has a problem, but can not offer any advice on how to fix it. What can I do with this truck? Does this qualify as a lemon?
