What's wrong?
The passenger seat belt anchor bracket on these 2019-2025 Mack trucks is the metal mounting point that holds the bench-seat belt to the cab structure. In normal use, that anchor gives the belt a solid connection so the belt can hold a passenger in position during a crash or hard restraint load.
On affected Md (Electric), Anthem (An), Granite (Gr), Md, and Pinnacle (Pi/Pn) trucks, the anchor attachment did not receive enough welding during cab assembly. Mack found that the weld nut plate was tack welded instead of fully welded around its perimeter. That leaves the passenger-side seat belt anchor with less strength than required, and the anchor bracket can separate under load.
There is no warning sign before failure. The belt can look normal in daily use because the problem is in the welded anchor behind the mounting point, not in the visible belt webbing or buckle.
