PACCAR Incorporated: Electronic Stability Control (esc)
PACCAR Incorporated reported this defect to federal regulators on Nov 25, 2020 and put the number of vehicles at risk at 11. The repair is free for as long as the recall stands.
The defect
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.
The risk
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.
The 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.

What this page is, and what to do next
A recall is not an opinion. It is a Part 573 report a manufacturer is required by federal law to file once it decides a defect poses an unreasonable risk to safety, and it commits them to repairing the vehicle at no cost to the owner. The three passages above are the manufacturer’s own wording as published by NHTSA.
This page describes the campaign. It cannot tell you whether one particular car has already been through the shop — that is tracked by VIN, and only the manufacturer knows it. Check yours at nhtsa.gov/recalls or with a franchised dealer, quoting campaign number 20V739000.
