Peterbilt 579 Recall 23V185: Parking Brake Valve May Stick, Risking Truck Rollaway

NHTSA campaign 23V185, reported March 20, 2023, 25 vehicles potentially affected.

What this recall means for you

Certain 2023 and 2024 Peterbilt 579 trucks may have an Intellipark Tractor Park Valve Module (PVM) that intermittently sticks in the un-parked position. When the park switch is activated, the valve may fail to move into the park position.

If the PVM does not engage park, the truck can roll away while parked, which increases the risk of a crash. Owners should take the recall seriously and have the truck inspected as soon as possible.

Dealers will replace the PVM with a new, corrected part at no cost to the owner. Owners who have questions can contact PACCAR customer service at 1-940-591-4220, referencing recall number 23PBC. You can also check your vehicle identification number (VIN) for open recalls.
