Great Buy
I've had this truck now for 4 months and have been very pleased with it. Biggest complaint is the interior. The overall layout looks great (pure truck interior), but the seat material looks to be made from the same material as the headliner in my prev last gen Chevy-it collects lint and your clothes stick to it. The floor under the backseat in the ex-cab isn't flat like the crew-hard to stick two 10" subs under. The gas mileage is lower, but what do expect from a bigger/heavier truck-get 17.5/20.5. However, it is faster than the last 4.8L's I've owned-3rd one now. This has a great ride quality, is super quiet and looks wonderful. Definitely GM's best truck yet.
Mileage is terrible
I have owned the truck for a few months and is overall a great truck, much more solid than my 2004 Chevy 1500. But the mileage I had on the old truck was 16-18 mpg and now I get 11 mpg. I have called the dealer and they keep telling me to give it some break in time. This is my fifth new vehicle and I have never had this problem before, I would really have trouble recommending this truck at this point.
6.0 ltr
Truck has plenty of power but the active fuel management 8cyl to 4cyl dosent work. The truck is to heavy and causes it to surge while driving down the freeway even on cruise control. No light in the engine compartment when hood is opened.
No complaints - Great truck
I looked forward to this truck arriving and haven't been disappointed. I like everything about my truck. Size, handling, performance. I am in the process of customizing the truck and there's not a lot I have to do. From four wheeling in the snow to pulling a large trailer to zipping down the highway, this truck's got getup and control. The only complaint I have is that the bottm half of the fuel tank disappears in a hurry, but for a 5.3 it's not all that bad. So far I've only experienced minor adjustments.
'07 Sierra
Love my new Sierra. Base level interior is top notch. Very smooth transmission and responsive engine. Gas mileage is poor, as expected. Very spacious interior. Looks pretty nice with my Rancho lift and 35" tires, real head turner. After 3 weeks I love it more than ever!
