Car Won't Start - Electronics Going Haywire

Yeah this is the battery as others have mentioned.

Unfortunately the optima battery is a tiny little piece of junk. I had to replace the original battery at 2 years and even the diehard 3 years after that! Stranded both times. Thanks Kia!

In any case this last time I bought a 5 year warranty battery at Walmart and I will buy a load tester from Amazon so at least I can start testing it every 6 months after 2 years and every 3 months after 3 years.

It also might be a good idea to keep a charged up battery jump starter in your Kia. It seems Kia engineers chose one of the smallest batteries and they die very quickly. In addition apparently car batteries don't last as long as they used to when I was growing up.

So I will see how well the 5 year warranty Walmart battery lasts.

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 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: https://streamable.com/fzst5

I checked the voltage on the battery and got around 12.53-57 so I don't think it's an issue with voltage. 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?
