    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. *TR
