PACCAR Incorporated (PACCAR) is recalling certain 2023-2024 Peterbilt 579 trucks. The Intellipark Tractor Park Valve Module (PVM) may intermittently become stuck in the un-parked position and fail to move into the park position when the park switch is activated.
A PVM that fails to move into park can cause a vehicle rollaway, increasing the risk of a crash.
Dealers will replace the PVM with a new corrected part, free of charge. Owner notification letters were mailed June 12, 2023. Owners may contact PACCAR's customer service at 1-940-591-4220. PACCAR's number for this recall is 23PBC.
