PACCAR Incorporated: Delayed Brake Timing/FMVSS 121

NHTSA Vehicle recall issued Sep 1, 2026.

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

Look up your 17-character VIN at nhtsa.gov/recalls. It shows every open recall on your specific vehicle, not just the newest one.

The repair is free at any franchised dealer for that brand — there is no expiration on safety recall repairs, and you never pay for parts or labor.

If the notice says 'do not drive' or 'park outside,' take it literally. Those wordings are reserved for fire and crash risks.

Register your car seat with the manufacturer. Car seat recalls reach owners only if the seat is registered.

Bought used? Recalls follow the vehicle, not the owner, so an open recall from years ago is still yours to get fixed for free.
