2009 GMC Sierra 1500 SLE 4dr Crew Cab 4WD 5.8 ft. SB (4.8L 8cyl 4A)
My only real complaint with this truck is the power/acceleration. I have the 5.3L Crew Cab with 6-speed AT, and unless I just have a lemon, this truck is a dog when it comes to acceleration. I literally get passed by Honda civics and the like with ease. The transmission sometimes feels like it is going to break apart; there are loud clunking noises quite frequently. It seems like the truck drives differently each and every time that I turn it on. I love everything else about the truck, but I just can't get past the very poor performance of the engine/transmission. This is more than likely due to the limitations that GM puts on the engines/transmissions due to the long warranty period.
Exterior look; quiet and smooth ride; good gas economy
Get rid of the limitations on the transmission/engine! This truck is weaker than my previous 2000 Chevy extended cab with the same engine.
