Overall, our 2007 GMC Yukon Denali's build quality was pretty good. The worst offense inside was the plastic trim that covers the rear seat mounts, which appeared to be glued to the carpet and not actually mounted to the vehicle. We also found a sloppily fitted third-row tray and cupholder that looked cheap and also showed poor fit and finish. We also found the A-pillars to be loose.

Outside, just a few things worth noting marred build quality. The rear bumper cover that hid the trailer hitch was the worse offender, loose and exhibiting terrible fit. We also found the grille's G-M-C lettering loose and rattling, poor fit of the plastic trim pieces that flank the rear window, and slight variance of the gaps around the rear window.
