What this recall means for you
Certain 2020 Kenworth T370 trucks with long wheelbase and larger rear axle spacing may be missing a second R12 relay valve in the air brake system. Without it, the brakes can activate later than designed, which does not meet federal air brake requirements under FMVSS 121.
The delayed brake activation can lengthen the distance needed to stop, which raises the risk of a crash. Owners should take this recall seriously and arrange service promptly.
The repair is free. Kenworth dealers will install a second R12 relay valve at no charge. Owners can contact Kenworth customer service at 1-425-828-5888, referencing PACCAR recall number 20KWA, and should check their vehicle identification number (VIN) for open recalls.
