2009 GMC Sierra 1500 SLE 4dr Extended Cab 4WD 6.5 ft. SB (4.8L 8cyl 4A)
So far this truck has been great and reliable. I drive it in mixed conditions and have not had a problem yet for reliability. The truck starts no problem when I don't have a plug in available in the cold(-42 the other week). The cylinder shut down for improved mileage does not seem to work overly well. Sofar the best mileage I've been able to pull is 15 mpg while cruising at 110 km/h.
Smooth running, command start, smooth towing.
Improve the cylinder shut down and make the 6 spd transmission standard.
