Can a low battery effect power steering on 2007 Chevy Cobalt?

Yes, a low battery in a 2007 Chevy Cobalt (or any car with electric power steering) can affect the power steering. The power steering in these cars is electrically assisted, meaning it relies on the battery and the alternator to function correctly. A low battery voltage can cause the power steering to become sluggish, difficult to turn, or even fail completely. The severity will depend on how low the battery voltage is.
