My speedometer quit working around 78,000 miles (GMC Sierra 2005 from local truck dealer center). Slowly but surely all my other gauges have quit working over time. The RPM gauge, speedometer, oil temp, and gas gauge. Only one works now. The rest either don't work or fluctuate back and forth. I would have reported this earlier if I knew about this site. It's not the first complaint so there is something up with these models. They should be recalled and fixed by the dealers. I won't ever buy another GMC vehicle. That's for sure.
