I have been having throttle response and other issues since I got my truck in late October. I stumbled across this post, and checked mine. I cannot believe GM approved this design and let this off the assembly line, the flex is insane. The actual pedal moves about a 1/2" before it even registers the gas is being pressed. I'm not nit picking as someone said earlier in this post. I wish I knew how to get a video uploaded. This is unacceptable in my book.
Has anyone had the dealer look at theirs? I'm sure its just another "that's normal" issue.
