For the 2021 Peterbilt 548. These apply to the model and year, not to one particular vehicle: check your VIN to see whether yours is included and whether it has been repaired.

Has your Peterbilt been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

Check your VIN with NHTSA

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Peterbilt dealer can also check your VIN. Recall repairs are free.
