Since I purchased this truck in June 2013, I've had several occasions where when the truck sits without being used for several days, when I back out of my driveway and put the transmission in drive, the transmissions slips. The truck won't move for a second, the engine RPM's race and then when the transmission catches, it will actually squeal the tires. Then at times it will continue to do this for the first several times I stop at a light or stop sign. This doesn't seem to happen once the truck has been driven for a distance, and it doesn't happen everytime the truck is used. I've talked to the service manager at the dealership and he says they've not had any issues with other trucks. I'm actually going to pick up the service manager and have him with me when I start my truck today after it has set for four days. I hope it does this with him in the vehicle so he can feel what's happening. I've been a loyal Chevy owner for over 30 years but I'm really disappointed in this truck which costs $45,000.

Transmission down shifts multiple gears when I decelerate. The first occurrence happened at 70 mph causing a very hard deceleration and near loss of control of the truck. I have had three other like incidences at speeds between 45 and 70 mph. These happened on dry pavement and I was able to slow safely. Had this occurred on wet or snow covered roads, I have no doubt there would have been an accident. 2. at times when I accelerate there is no throttle response for several seconds. When the engine does respond, the truck accelerates as if I have the throttle floored. Again this has happened on dry pavement. Slick conditions would have caused a spin out. 3. vehicle surges between 20 and 45 mph. Engine RPM continually jumps 200-300 RPM causing constant surging. Besides being very annoying, it would be dangerous on icy roads.
