“Electrical fire in driver's side door of 1999 Gmc Sierra 1500 pickup. Heavy smoke damage, door panel destroyed, trim around the door desstroyed and small area of carpet burnt by door”
NHTSA complaint #10003492, filed 2003-01, 49,700 miles“We own a 1999 Gmc Sierra pickup. The odometer and shift indicator are the LED type. Both the odometer and shift indicator have shorted out and there is no way to tell what the mileage is or what gear the truck is in. This has resulted in two incidents where people were nearly run over because the driver did not know if the truck was in forward or reverse. Also, although the odometer measures mileage, we can't read it because the display is dark. …”
