Car Won't Start - Electronics Going Haywire

34828 Views 14 Replies 13 Participants Last post by  Derekm27
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?

I've been having the same issue with my 2013 optima hybrid LX, however I just replaced the battery ~6 months ago. It was fine for a while, then the last few weeks every few days it's been saying "key not detected" and won't start without a jump and most recently had the same noises/clicks issue.
