February 21, 2010My wife and I just purchased a 2007 2500HD Duramax Crew Cab. We have another few months before the bumper-to-bumper warranty expires. There is still the Powertrain Warranty until 10 years or 100k miles, but we`re trying to decide if we should invest in an extended warranty. This is our first diesel pickup and aren`t sure what to expect in the way of repairs due to failure. We have purchased extended warranties for the two Tahoes that we`ve owned and had to use it quite a bit on our `02 Tahoe. I know that extended warranties can be one of those topics that can generate a wide spectrum of opinions, so I`m interested in what has or has not worked for others.
