I bought my 2010 Crew Cab Z71 with 15k miles on it on March 3, 2011. I have not had any problems with it other than the exterior temperature gauge takes a while to register what the teperature it outside. Also, it is pretty difficult to park, even with the back up camera and parking sensors. I get about 15-17 MPG in town and 19-20 hwy.
Purchased a new 2010 Silverado and after 200 miles the interior noise became unbearable on the highway. Sounds like the rear passenger door of the crew cab is not closed. The door is closed, but the cab vents behind the rear seats are allowing for loud road noise. Wind noise can be heard though the weather strilling around the doors at hiway speed. Went back to the GM dealership to complain, and even though they admited that my vehicle is louder than most vehicles, I was told that "they all sound like that". I find this an unacceptable answer. The dealership offered to Duct Tape over the cab vents, but this would make closing the doors difficult.
Wasn't looking for a pickup, but with the incentives ($10k off sticker) and tax credits it was a no brainer. This is one fine machine, drives like a dream. First tank and a half, 23.5 mpg at 60-65 mph. This truck looks amazing with black granite metallic paint, chrome wheels and chrome running boards. Got all of the toys avaialble except for the dvd player in back, this thing coddles you. Very pleased that my buy American initiative has had such a good result. Way to go Detroit.
Purchased our 2010 Silverado from Michael Hohl in Carson City, NV because I wanted a 4x4. Found this truck, and it's been comfortable and reliable with 18000+ miles on it, it is my vehicle of choice for road trips due to reliability, comfort, and gadgets such as USB port and ONSTAR. Had a little Colorado before that, which was a sweet little truck as well. Sorry I had to trade it in.
