Soon after I submitted my first review on this forum my Colorado developed a cylinder head/valve train issue. It's going back to the dealer for a cylinder head/valve replacement next week. Apparently this has developed into a common problem for the I4 and I5 motors. The notion of having my engine torn apart this early on hasn't done much for my owner experience and to make things worse GM won't extend my drive warranty. For GM to continue to have these kinds of quality problems is very frustrating to me. I'd prefer to support the American manufacturers but I'm not sure I can afford to nor even want to anymore.
