GMC Sierra MultiPro Tailgate Maintenance Guide

GMC's MultiPro tailgate adds an inner gate, load stop, and multiple pivot points that a standard one-piece tailgate simply doesn't have. That added functionality means more hinges, latches, and sensors that need periodic attention to keep working smoothly.

If a panel won't latch or the inner gate won't fold, check for debris in the hinge pivot first, then inspect the latch sensor for grime before assuming it's an electrical or motor failure. Most MultiPro complaints trace back to simple mechanical buildup rather than a failed component.
