My 09 does that all the time. It frustrates me to no end. The GM garage said it's due to the electronic throttle b/s. Between it acting so sluggish all the time and the transmission slipping and clunking, I'm really disapointed with it. Even with that new 6-speed I'm still only getting 12 mpg roughly. But that may be due to the simple fact that I'm only 20 and I tend to drive aggressivley.
Drive by wire is the standard today.
