Waking up to a dead battery on a Chevy Equinox almost always means a parasitic draw. Here’s how to find the culprit and stay safe on the road.
Why does my Equinox battery die overnight?
If your Chevrolet Equinox III starts fine in the evening but is completely dead the next morning, you're dealing with a parasitic electrical draw. This happens when a module, light, or switch stays powered up after the vehicle is locked and should have gone to "sleep." The most common troublemakers on this generation are the glovebox or trunk lights, a door latch switch that doesn't close, and the Body Control Module (BCM) that fails to shut down the infotainment or OnStar telematics unit. Even a vanity mirror light left slightly ajar can pull enough current to flatten the battery overnight.
