The problem

PACCAR Incorporated (PACCAR) is recalling certain 2021 Peterbilt 348 and 579 vehicles. The spring brake chamber may have been assembled with incorrect springs that were out of specification, which may cause the pressure plate to shift.

The risk

The pressure plate may tear the diaphragm, causing a loss of air pressure and increasing the risk of a crash.

The fix

Dealers will replace brake chambers, free of charge. Owner notification letters were mailed on July 9, 2021. Owners may contact PACCAR (Peterbilt) customer service at 1-940-591-4220. PACCAR's number for this recall is 21PBE.

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
