"Have had this truck for almost 3 years, have had a few warranty issues, transmission problem, all my speakers died but all that was fixed and covered under the warranty. Mine is a 2007, got it Dec 2006, some popping when you make a sharp right turn, cannot be diagnosed for a problem though, was not happy when I found out that you cannot buy regular windshield wipers to replace, you have to go to the dealership and buy them, $20 a piece....other than that I love my truck and I am glad I have it. I live on a bumpy dirt road and it has lasted very well."
"I just purchased this vehicle, and I must say, I have thoroughly enjoyed it from every aspect. The fully loaded LTZ is what I have, and I must say this vehicle has really come a long way compared to the earlier releases of this vehicle. It is very roomy and comfortable.
Pros - I like almost everything about it. The ride is as smooth as the Escalade (for $10,000+ less). It's not ridicuously bad on gas, compared to its competitors.
Cons - Gas, though good for a big truck, is still bad overall. Bluetooth, because of ONSTAR, it doesn't have it.
Overall, I would definately recommend this vehicle to anyone looking for a pick-up truck\SUV."
"This vehicle is the best of all worlds. Can be used as a truck with plenty of room in the covered bed and a family vehicle. Very good towing capacity with towing package. gas mileage acceptable for an almost 6000# vehicle."
