What owners wrote
Erratic speedometer, works sometimes, sometimes stays at 0 miles an hour, sometimes reads 30 or so miles an hour at a complete stop.
The speedometer stopped working at approximately 85000 miles. This is a known problem with 2005 avalanches but for some reason this VIN was not included in the recall.
