PACCAR Incorporated (PACCAR) is recalling certain 2022 Kenworth T180 and 2023 Kenworth T280 and Peterbilt 535 vehicles. The ABS telltale was not enabled on certain vehicles, and will not illuminate even during an ABS malfunction. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 105, "Hydraulic and Electric Brake Systems."
An inoperational ABS system may not notify the driver of a malfunction, increasing the risk of a crash.
Dealers will perform a complete software update to correct the parameter setting, free of charge. Owner notification letters were mailed December 9, 2022. Owners may contact PACCAR's customer service at 1-425-828-5888 (Kenworth); 1-940-591-4220 (Peterbilt). PACCAR's number for this recall is 22KWC and 22PBC.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
