NHTSA Complaint #10433769 — 2011 CHEVROLET SILVERADO 1500

THIS IS A DEALER DEMO VEHICLE, FIRST 2235 MILES WERE DEMO. DURING MY FIRST MORNING (12HOURS AFTER PICKING UP AT DEALER) OF OWNERSHIP I WAS DESCENDING DOWN A HILL WITH THE CRUISE ON, AND THE VEHICLE PROCEEDED TO OVER SPEED APPROXIMATELY 5-7MPH. I TRAVEL THIS HILL BOTH WAYS TO/FROM WORK DAILY AND THIS HAPPENS EVERYTIME. I THOUGH THIS MIGHT BE AN ABNORMAL ADJUSTMENT WITHIN THE COMPUTER/ETC SO WHILE TAKING IN TO THE DEALER FOR A TPMS (TIRE PRESSURE MONITOR SYSTEM) ISSUE I MENTIONED THE OVERSPEED ISSUE TO THE SERVICE WRITE UP AND THEY SAID THAT IT WAS NORMAL. I DON'T AGREE, BUT MAYBE IT IS. IT DOES ADJUST BACK TO NORMAL CRUISE SET SPEED BUT IS UNIQUE. I HAD A 2002 DODGE RAM 1500 PREVIOUSLY AND IT DID NOT DO THIS, AND I HAVE DROVE OTR (OVER THE ROAD) SEMI-TRUCKS AND KNOW THE DIFFERENCE WITH OVERSPEED BEING NORMAL AND ABNORMAL. I WOULD LIKE THIS TO BE LOOKED INTO, AS IT COULD BE A HAZARD THAT COULD LEAD TO UNSAFE SITUATION. *TR
