Problem 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." Risk Delayed brake response time can increase the risk of a crash. Fix 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.

Two numbers, one recall

Every safety recall carries two identifiers. 26PACF is the number Peterbilt assigned in its own system: it is what appears on the owner letter, on the dealer’s service screen and on the repair order. 26V567000 is the number NHTSA filed the same recall under when the manufacturer reported it, and it is the one every federal record, this site included, is keyed on.

The repair is free by federal law for vehicles up to fifteen years old. Whether one particular vehicle is included is settled by its VIN against the manufacturer’s build list, not by its model year.
