My dashboard starts going crazy after driving the car for longer than 5 minutes. Can someone tell me what's going on?

Asked by May 22, 2014 at 02:56 PM about the 2010 Chevrolet Cobalt

Question type: Maintenance & Repair

The fuel gage goes to empty.  The speedometer either goes to zero or it just bounces up and down.  The RPM gauge goes up and down.  Low Fuel or Power Steering messages pop up where the tacomter display is.  You can't tell how fast you are going or how much gas you have and it jerks sometimes.

Mine did something like that and I cured it by replacing the battery. Get it tested first, but its possible its something electrical like that. Modern cars are extremely sensitive to things like improper voltage and do strange things. A 2010 seems a bit new to be needing a battery already, but they don't last forever and any time after about 5 years they need replacement.

Chevy is known for electrical problems. Mine started doing it a few months ago, and I scoured the internet for a definitive answer. It could be a few reasons. A bad battery, bad grounding, or, in my case, its a screwy ECM. My quick fix for it is to turn off my car, and smack the panel that covers the ECM a few times. It works for me. It seems to do it when the interior gets too hot, so I'd assume its a bad connection somewhere in there. I'd suggest checking your battery, cleaning the grounds for your car, and checking to see if it is your ECM.
