I've been looking at buying a new vehicle. I'm looking mostly at 2010 Chevy Suburban and '10 Cadillac EXT's. My father owns a 2008 GMC Sierra Denali and for the ease of it I have been considering buying his truck. In my research I've read a little bit about that engine having some issues. Specifically some knocking and what not. Can anyone elaborate on this for me? Is it a common issue or not really? Is this vehicle notorious for anything else? It's a 2008 GMC Sierra Denali AWD V8 6.2L. Thank you in advance!
