Nothing yet that I can find except the engine block heater cord is very hard to find a way out of the engine to the outside of the truck.
The engine has a hard time staying in cruise control when winds are over 30mph.
This is the best 4x4 truck that I have had in years it gets great gas mileage as I drive an average of 100 miles a day to and from home to work.
I average 19 to 21 mpg and this is great for a truck.
Not really, I get between 18 and 22 on the highway with my K-1500 Silverado with a 350 V8.
Ya of course you are going to get that.. ON THE HIGHWAY, the reviewer means combined, the colorado is a great truck!
