2005 Chevrolet Impala Question: Instrument panel

My tach no longer works and getting false overheating. Needle pegs and engine runs as normal with fans on. Coolent is full and no leaks. 37000 miles. My question is,before I bring to dealer, is this covered by GM? I have read online of other cases like this.Seems to common. -

This is very common on the 03-06 GMs. The cause is the motors behind the gauges are failing, they all go out eventually. You can get it repaired here - www.drspeedometer.com and there's a DIY guide here - www.howtorepairmyinstrumentcluster.com -
