The second row center seat belt routing may make it difficult to position correctly on smaller passengers. If the seat belt rides up to fit around the abdomen, the risk of internal injury is increased in a crash. Dealers will cut the guide loop, remove a portion of the loop, and the remaining sides should be folded over and secured with a retainer. The recall began July 21, 2005.

Mine has been a great truck! Love the quad steer, The brakes are quite weak.
rear steer is crap ,, when it goes bad ,it goes real bad vary expencibe to fix and no one kniows how to fix them
The Auto Mode Air Conditioning system on the driver side is giving me some annoying problem. When I set the temperature, say 68 F and it start to blow cool A/C air and after some 10-15 minutes it change to very hot air. It will not change to cool breezy air even if you turn and change the temperature knob setting. I tried to turn it off first then turn it back on but still will not go back to cooler air temperature. I tried other A/C modes but it will not respond. The only way to reset this, I found out , was to turned off the ignition key, shutting down the engine then start the engine again. It is dangerous to do this while driving in the freeway. So either I have to exit and pull over to turn off and start the engine again to get some cool air or continue driving in the Hawaiian summer heat in the hot interior truck cabin. Is this a common problem? Does anybody out there experience this? The passenger side A/C is fine. I am thinking of putting a separate switch for the A/C so I can reset it without stopping the engine.
The rear bumper on my 2005 GMC Sierra Denali is rusting all to hell.
6.2 liter sounds like a deisel-very noisy. 6 speed trans vibrates in 6th gear. Dealer said they all do that! Still trying to get fixed under warranty. DON'T buy a 2010 Sierra Denali!
