What this recall covers

NHTSA's campaign record, quoted as published

The defect

PACCAR Incorporated (PACCAR) is recalling certain 2027 Peterbilt 548 trucks. The front brake valve and hoses may be the incorrect size, which can delay the rear service brake application and release, as well as the trailer gladhand application times. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."

The risk

Delayed brake response time can increase the risk of a crash.

The remedy

Dealers will replace the front brake valves and hoses, free of charge. Owner notification letters are expected to be mailed October 31, 2026. Owners may contact Peterbilt's customer service at 1-940-591-4220. PACCAR's number for this recall is 26PACF.

A safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
