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?

You probably need a new battery. Mine did the same thing (2016 SX). Jump start it and drive to Walmart. Their batteries are supplied by Johnson Controls, which is a good company. Depending on model, you might need an AGM battery, which is $200 at most other places. Like $150 at Walmart. Good luck.
