P0562 on a Chevy: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

You can usually drive a Chevy for a short time, but a failing charging system will drain the battery and can leave you stranded, so get it checked soon.

What P0562 means on a Chevy

On a Chevy, P0562 means the engine computer sees system voltage below about 10 volts. Chevy trucks and SUVs rely on a strong charging system, so a weak battery or failing alternator is usually the cause.

Is P0562 common on Chevys?

P0562 is common on Silverados, Equinoxes, and Malibus with aging batteries or failing alternators. Battery terminal corrosion is a frequent issue, especially in colder climates, and on trucks the alternator can fail after high mileage and drag system voltage down.
