2007 Chevrolet Avalanche LS 4dr Crew Cab SB (5.3L 8cyl 4A)
We have owned our Avalanche for 1 year, and still are glad we bought it. Fuel mileage has increased, now getting about 21-22 mpg if we keep the speed at or below 75 mph. The 4 cyl mode started kicking in noticeably more once we passed 15,000 miles. Some minor squeaks started in the trim, but tighentened a couple of screws and they have gone away. Only minor problem we have had is with the door handle pulls, metal has started to delaminate from the plastic at the edges, fixed it with super-glue until we can get it into the dealer. It's a cross country machine, 500+ mi on a tank of gas, 1000+ mi a day with minimal driver fatigue. Makes the trip between Reno & LA a breeze.
Drives & rides very well for a vehicle its size. Displacement on demand, 310 hp, 330 lbft torque, 20+ mpg highway. Steering wheel cruise & audio controls big improvement over turn-signal does all.
Bigger glove box, side airbags standard on all models. A 6-speed auto trans to further help the mpg. Expect to get a lot of people flashing their hi-beams at you due to bright lo-beam headlights. Slightly bigger side-view mirrors with the reverse function like the Silverado.
