“The problem: the speedometer works intermittently, the brake light would come on, and the brakes would lose power. I took it to the dealer to get fixed. The brake light doesn't come on anymore. The dealer has changed all the components on the front and rear brakes. Now the brakes are really mushy and the truck pulls to the right. The dealer changed the speed sensor, but the speedometer doesn't work. My truck has been at the dealer for more than 2 weeks.”
