Bought new, Loved everything, wanted to keep until wheels fell off. Then, the rear-end fell out of my dream! At 96,000 rear-end had to be rebuilt. 38,000 later, pulling a 12 ft trailer, rear-end went out again. Replaced with a rebuilt one. Just a few thousand miles & I can hear the familiar hum again. Many Avalanches must not have this problem, but if you got one with a faulty rear-end, it must be faulty from the factory, and can't be corrected. I'm now figuring, any rebuilt you buy is one of the faulty ones that can't be really fixed. So I guess I'm in a fix, unless I get one off a wrecked truck & pray it's from a truck with a good rear-end. But this is spending around $1100 to $1400 everytime.
Purchased 07 AV LTZ, with 43K mi black on black with Nav/Cam, on 11/27/2010 after test driving, Ford F-150, GMC Sierra 1500 SLT, Chevy Silverado 1500, Toyota Tundra Limited. I was close to getting the Tundra but preferred the look of the exterior and interior of the AV much better. I test drove it for a week before my final purchase. I've only had it for six days, but it looks, runs and feels great. I have a tendency to use the cruise control as much as possible and have been getting about 16.5 mpg in the city. This is not my everyday car but I wanted a truck that looked great and could make runs to Home Depot, haul away debris from my DIY projects. SUV insurance rates not a truck.
Exterior and Interior looks. The plush leather seats and wood trim inside. Memory seats for 2 drivers. Easy use of Nav. Great rear camera. The engine switching from V8 to V4.
Nothing yet as I've only had it six days. However, something to help protect the plastic bed cover and fins as the sun tends to discolor them.
Developed a rear main seal leak when I first bought it. Panels around the vents began to oxidize from the air conditioning. Love the turning radius. Like the midgate. Sound system is pretty good. Generally got 11 mpg city, but was surprised at the 6-7 mpg jump on the highway.
Bought one of these in 07 as a program vehicle with 5000 miles. Loved it, but when gas prices went up to over $3.50 we traded in for a Saturn Vue. BIG mistake. Didn't know what we had till it was gone. My wife decided she wanted a big truck again recently. She wanted a truck, but with all the bells and whistles normally found in SUVs (heated seats, DVD, nice interior). Looked at everything out there and fell back to the Avalanche. Bought another 2007 model this year with 44,000 miles and love it, again. Will not sell again, I don't care if gas goes to $10.00 a gallon.
Exterior looks, especially with the 20 inch wheels. Ride comfort. Covered, versatile bed. Every option I can think of is in this truck (LTZ model).
Better gas mileage. More aggressive power and sound. The power is adequate, but I like fast vehicles.
I've put 109,000 miles on this truck in 30 months only having to replace an evap sensor at about 65.00. The ride is superb. My family actually looks forward to trips in this vehicle. I always liked the Av, but didn't buy the earlier model because of the plastic body cladding. When we wear this one out will definitely by another.
