Agency product description and boundaries

PACCAR Incorporated (PACCAR) is recalling certain 2026-2027 Peterbilt 579 and 2027 Kenworth T680 tractors. The trailer air connection quick release (QR) valve in the air brake system may have been incorrectly installed, which can cause the trailer to become unstable after the driver applies the brakes. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."

Still to verify: match the label on your item with the full official notice, including any exclusions, tables and photos. Some identifiers appear only on the agency website and are absent from this data feed. A missing field does not mean all versions are affected.

If your lot or date falls outside a stated range, this notice has not established that your item is affected. This is not a finding about other recalls or product safety.

Vehicle-specific check required: use NHTSA’s official VIN lookup. Fresh Recalls has not checked a VIN or repair status and does not ask you to submit a VIN.

2. Agency hazard and consumer action

NHTSA reports: An incorrectly installed quick release valve that does not function properly can increase the risk of a crash.

NHTSA consumer action: Paccar inspected and reinstalled the valves, as necessary, free of charge. All affected tractors have been repaired and therefore no owner notification letters are necessary. Owners may contact Peterbilt's customer service at 1-940-591-4220 and Kenworth's customer service at 1-425-828-5888. PACCAR's number for this recall is 26PACC.
