"Have had my sierra for about 2 years now and never had a problem, other than routine maintenance. I take my truck off roading quite frequently and its always up to the challenge. Its a great dependable truck."
"Best all around vehicle I've owned, and I've owned 30 in my day. Bought new in 2009 and now have 50k miles with two very minor problems, both fixed within an hour. Much better than ANY other new vehicle I've purchased. It has great style; is comfortable to take on a long trips and has all the "HD" you would expect in a truck like this. Towing power is unbelievable!! Now if diesel fuel would just get cheaper......"
"Traded in my 2008 Silverado with 115000 miles on it and no issues at all. This Sierra is just getting broke in, but has already pulled my 28 foot airstream to Florida twice, south Carolina and multiple trips through the mountains. I would not hesitate to buy another one"
Pros: "Great Price, rides great, onstar app for iphone is great."
Cons: "transmission runs a bit hot when towing, 5.3 is a bit weak compared to 5.7 hemi and 5.0 ford engine"
Likely to recommend this car? (1-10): 10
"only downside i really have to say is that towing a 4k pound boat the transmission gets up to 200 degress in 75 degree weather. Aside from that this truck is perfect, quality, ride, value for the money.. everything."
"Like a work truck should be, its a reliable good looking pick up that doesn't cost $50k. My only complaint is that with the V6 it is a little sluggish In the steep hills. The 4 speed tranny can't make up its mind what gear it wants. The engine needs more power. Get a V8, and problem sloved. Seats are a benchmark in the pick-up category."
"Bought new after owning many Fords and wow won't look back. Great motor, great ride full or empty. I have GM Goodwrench intake, Flowmaster exhaust, and Edge Evolution programmer on it woke her right up. Glitch in tranny but not too bad."
"Simply put, powerfull, dynamic, stylish, compfortable and by far the best riding pick-up I have ever experienced. I test drove Ford and Dodge and they could not even come close to the 2008 GMC Sierra, 2500 HD 6.6 Liter Turbo, Allison Transmission. 660 LBS Torque. Pulls my 4,000 LB boat like it is not even there (1400 RPM at 60 MPH) and my 10,000 LB 5th wheel travel trailer with ease."
