Certain lights in dashboard controls are burnt out. Right now the problem just involves the tachometer, ignition illumination and driver heat/cool control indicator. Problem is manageable during the daytime but at night, necessary parts of the dashboard do not illuminate. The problem is that the lightbulbs themselves cannot be replaced. The whole control board for that particular part of the dash ($300. 00) must be replaced which is ridiculous on a four year old car.
The speedometer displays the wrong speed. It started with just higher speed and now will display 20-30 mph when traveling on expressway when going 65. Sometimes the instrument cluster can be reset by turning off and on the ignition to reset. Now even that is not working. I took to dealer today and they want to replace the instrument cluster for over $537 ++. The chevy dealer I bought the car from is no longer in business. This started around 60k miles.
