Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“If the brakes are pumped 2-3 times the peddle will become really firm and hard to press. When this occurs the truck will not stop. You have to stand on the brake pedal with both feet to get the truck to stop. Pretty unnerving for a 75k mike truck still under drivetrain warranty but not covered. I use this truck for work and hauling my kids. I don't like having my kids in this vehicle!”
