Summary

PACCAR Incorporated "PACCAR" is recalling certain 2020-2021 Peterbilt 520 vehicles. The stability control brake relay may have the Spring Brake Modulating "SBM" Valve or the lift axle hose incorrectly connected.

Consequence

A stability control event meant to only actuate the ABS controlled wheel ends could actuate lift axle brakes or modulate park brake chambers and could possibly de-stabilize the vehicle, increasing the risk of a crash.

Remedy

PACCAR will notify owners, and dealers will inspect the suspect chassis and correct the brake relay plumbing if needed, free of charge. PACCAR has issued owners an interim notification on January 4, 2020. Owner notification letters were mailed on January 25, 2021. Owners may contact Peterbilt customer service at 1-940-591-4220. PACCAR's number for this recall is 20PBF.
