Example complaints
Brakes: “Tried to stop at red light ,and the brake pedal went all the way down I had to jump the curb not to hit another car. My husband came and looked at the truck and saw the brake lines were rusted through and fluid was coming out. He put a whole can of brake fluid in so that I could move the truck down the street to a service center. Again the repair man said all the brake lines are rusted out. We repaired one a summer ago with the same issue.”
NHTSA complaint #10574775, filed 2014-03, 94,000 milesTransmission and drivetrain: “My husband was driving with my four children going about 5mph when he went to make a left turn and lost the power steering. Being so close to home, he was able to drive it home. My husband also noticed that an axle seal was leaking as well and this was also considered common for problems. We use this vehicle as our only family car, so naturally we had it fixed right away. …”
