Here are the details:

2015 Kia Optima automatic 75k miles

I was driving today and my car turned off out of the blue. A bunch of lights came on in the instrument cluster and I was able to coast to a safe spot.

When trying to start the car there is a very short sound indicating it is trying to turn over, but maybe 1 second of this then silence. No clicking or whiring.

My friend came and tried to jump start my car. Before attaching jumper cables I checked my battery voltage and it was 12.4V. After 15 minutes of charging my car would still not start. Even with the jumpers still attached from his battery.

I went to AutoZone and borrowed their code reader, but it came up with 0 codes.

I checked every fuse and they all appear fine.

My thoughts are it could be the ignition coils or starter, but wanted to get another opinion before swapping things out.

Any ideas? Thanks in advance!

Edit: it turned out to be the engine has seized and it is being replaced for free under the recall. Got a 2023 Stinger as a loaner and very happy with how this turned out. Such a relief. I am considering selling my Optima and going Subaru or Toyota.
