What's wrong?
The center bench seat belt in the 2026 Mack Md is the belt assembly for the middle seating position on the bench seat. It is supposed to route through the tongue, the metal latch plate that clicks into the buckle, so the webbing sits flat and locks correctly when loaded.
On affected Mack Md trucks, the supplier assembled the seat belt with the belt routed incorrectly through the tongue assembly. That routing error changes how the belt moves through the latch plate. A correctly routed belt keeps the webbing in the intended path so the belt operates as designed during a hard stop or crash.
Owners are not expected to notice a dashboard light, sound, or visible driving symptom from this problem. There is no warning sign before failure, so the VIN check and dealer inspection decide whether the seat belt assembly is included.
