2021 Peterbilt 348 & 2021 Peterbilt 579 recall: brakes
⚠️ What's wrong
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.
Is the fix free? Yes. Safety recall repairs are free at any authorized dealer under federal law, including parts and labor. (Vehicles more than 15 years old when the recall was announced can be excluded, but most manufacturers still fix them.)
