Car Won't Start - Electronics Going Haywire

Hey everyone,

When trying to start my car, it does not start, makes a clicking noise, and all the electronics are going haywire. Headlights, dash, interior lights rapidly flashing, sometimes it says the key isn't detected, sometimes it says refuel. When trying to unlock/lock the car, the mirrors aren't folding out and the lights rapidly flash.

Here's a video of a little of what's going on: Streamable Video

I checked the voltage on the battery and got around 12.53-57 so I don't think it's a voltage issue. Connections are clean and secure on the battery leads. The car was driven with no problems roughly 4 hours ago, so it is not an issue with it sitting for a long time.

Any idea what this could be?

The clicking sound you hear when trying to start the car is the starter solenoid, which is caused by a bad battery. The voltage may be okay under no load conditions, but not okay when loaded by the starter motor. This is due to high internal resistance in the battery. An auto parts store (Pep Boys, etc.) can run a load test to determine battery health.
