I STARTED MY VEHICLE 4 DAYS AGO AND THE SPEEDOMETER AND GAUGES WERE FROZEN AND DID NOT OPERATE AT ALL. I DROVE TO THE STORE AND THE GAUGE REMAINED AT 0 THE ENTIRE TIME. WHEN YOU ACCELERATE THE SPEEDOMETER DOES NOT MOVE FROM 0 MPH. I TURNED THE VEHICLE OFF AND TURNED IT BACK ON AND THERE WAS NO CHANGE. YESTERDAY WHEN I STARTED THE VEHICLE THE GAUGE WOULD ONLY MOVE BETWEEN 30-50 MPH. TODAY WHEN I STARTED THE VEHICLE IT IS FROZEN AT 120 MPH AND THE KHM(?) DOES NOT MOVE PAST 1.WHEN I ACCELERATE NEITHER OF THE TWO GAUGES ARE FUNCTIONING. I HAVE YET TO REPAIR IT BC IT HAS HAPPENED JUST A FEW DAYS AGO BUT I WAS TOLD THAT I AM LOOKING AT A VERY LARGE REPAIR COST TO REPLACE THE ENTIRE DASHBOARD CLUSTER. THE SAME THING HAPPENED IN MY 2003 MODEL AND I SOLD THE VEHICLE. AS WELL THE REAR SUSPENSION IS LOWERING ON ITS OWN TO THE LOWEST POSITION AND DOES NOT GO BACK TO THE NORMAL HEIGHT.

IN THE MIDST OF TRAVELING ON VACATION, THE SPEEDOMETER AND MANY OF THE OTHER DASH COMPONENTS JUST QUIT WORKING. I HAD TO RELY SOLELY ON THE PORTABLE GPS TO DETERMINE THE SPEED THAT I WAS GOING. THIS IS UNSAFE, AND THIS IS AN ISSUE THAT HUMMER MOST CERTAINLY NEEDS TO CORRECT.
