What this recall means for you
Certain Peterbilt 320 and 520 trucks from model years 2016 through 2019 have dual foot valves and a liftable tag or tri-drive rear axle, and the rear brake signal hose may be missing a quick release valve. This can delay brake release timing, so the vehicle does not meet the requirements of Federal Motor Vehicle Safety Standard 121 for air disc brakes.
A delayed brake release may increase the risk of a crash. If you own an affected vehicle, PACCAR will notify you directly. You can also contact PACCAR customer service at 1-940-591-4220.
The repair is free. An authorized dealer will check the vehicle for a quick release valve and install one if needed. Check your VIN for open recalls to confirm whether your truck is affected.
