The air tanks have an insufficient volume of air for the brake system. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."

Risk: Insufficient air volume can reduce braking performance and increase the risk of a crash.

Remedy & notes

Dealers will install the correct volume air tanks, free of charge. Owner notification letters were mailed August 12, 2024. Additional owner notification letters were mailed October 27, 2025. Owners may contact PACCAR customer service at 1-425-828-5888. PACCAR's number for this recall is 24KWD.
