What’s up with Chevy Spark batteries?
I drive a 2020. The battery has gone dead twice since I’ve had it. The first time was in late August of 2025, and the second time was two days ago, October 2026. I took it to AutoZone and they ran a test and said my battery was fine, but the starter was going bad. I took it to a mechanic, and they said it’s the battery going dead. They also said “something” is draining the battery while my car is turned off. I have my phone plugged in while I’m driving, but I unplug my phone (and charge) when the car is off.
Is the radio using power while the car is turned off? I can’t think of anything else that would be. I never turn the overhead light on…
