“Chevrolet avalanche instrument cluster failures. Over the past 32 months the instrument cluster on my 2003 avalanche has been intermittently malfunctioning causing the speedometer, fuel, temp, oil pressure and all other gauges to not operate. As of 1/19/2008 all of the gauges on the instrument cluster failed completely. From what I understand Chevrolet has issued a extension of the warranty to 70,000 miles for this single issue but this is a safety related problem that should be taken care of under a recall of all vehicles with this instrument cluster.”

NHTSA complaint #10215531, filed 2008-01, 54,000 miles
