The transmission on this vehicle went after only 2 1/2 years, and at 42,000 miles. I don't tow with it, or use it for work. Most of the miles on it are highway, none off road or abusive. Chevy didn't want to know anything. They told me I should have purchased an extended warranty. This in my opinion, is telling me that they know the Chevy Avalanche is substandard and I will have problems with it. I don't know of any car company that backs their product less then Chevrolet. I'm very disappointed with Chevy.
The Avalanche has the potential of being a great all round vehicle. They just need Honda or Toyota to make it for them, the right way
Transmission and a better warranty. If they build quality they would be confident in their product and give a better warranty like other companies
