BELLEVUE, Wash. – PACCAR has agreed to recall certain 2021-2022 model-year Peterbilt vehicles to address a potential loss of rear-braking capabilities.
The 163 vehicles – Peterbilt 367, 389, 567 and 579 variants — impacted by the recall report, affected vehicles, might have been produced with insufficient clearance between the Hill Start Assist valve assembly to the rear axle when rear suspension is lowered.
According to the National Highway Traffic Safety Administration (NHTSA) Part 573 Safety Recall Report 21V-648, “If hose or fitting comes into contact with rear axle the hose may become kinked or the fitting could break. Either form of damage could interfere with transmission of rear-brake signal.
“If hose or fitting damage causes reduction in or loss of rear brake signal, the vehicle could experience reduced rear braking capability or loss of brakes to the rear axle(s), which could increase the possibility of a crash.”
The remedy is for dealer service techniciants to re-work assembly to conform with updated design if more clearance is needed.
Dealers and customers are scheduled to be notified beginning Oct. 18th.
