2011 GMC Sierra 1500 sle crew cab z71 4x4 coming off of the expressway and coming to a stop at a traffic light I applied brake pressure.

Second report - sudden acceleration. 2011 GMC sierra pu truck. On December 20, 2010 I was traveling to visit friends. While on highway I set the cruise control for 70 mph. I exited the freeway and traveled approximately 5 miles on city streets. Upon entering a bedroom township known for speed traps I attempted to engage the cruise control for 30 mph. When pressing the cruise control to set the speed I was traveling (30 mph) the truck down shifted and accelerated rapidly (to 4000 rpm). I immediately tapped the brake and the cruise control disengaged. This is the second time for this truck to down shift and accelerate rapidly. A previous report was made in November 2010.
