Kenworth recall: Service brakes, hydraulic
What is wrong
PACCAR Incorporated (PACCAR) is recalling certain 2020 Kenworth T370 long wheelbase vehicles with larger rear axle spacing. The vehicles may be missing a second R12 relay valve, causing increased brake activation timing. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."
What could happen
Increased brake activation timing may lengthen vehicle stopping distance, increasing the risk of a crash.
The fix
PACCAR will notify owners, and Kenworth dealers will install a second R12 relay valve, free of charge. PACCAR issued owners an interim notification on April 14, 2020. The recall began May 6, 2020.
