But that may be due to the simple fact that I'm only 20 and I tend to drive aggressivley.

You have other problems beside a lead foot if you are only getting 12 mpg.
Drive by wire is the standard today.

It acts just like you never pushed the accelerator.
I called Chevy and they left me a message to call back.
Let's see what happens.

My 09 is doing just like you said just recently started.
