press the start button on and then I hold it down to start and it goes straight to goodby?

If your 2013 Kia Optima only says "goodbye" and does not start when you press the start button, it suggests an issue with the vehicle's starting system.

If the battery is okay let's run a CAN scan to see if any codes are stored.You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how

Here is a guide to help you test the battery and how to change it out in case it fails the test, also you can take the battery to the auto parts store so they can test it as well.

Check out the images (below). Please upload pictures or videos of the problem so we can see what's going on.

Thanks for the information and I appreciate it. I'm not sure yet but I'm leaning towards the brake light switch. I couldn't get any power to the brake switch fuse. So, I'm going to start with a new switch and see what happens. Thanks again and I will let you know if I get it fixed.

Okay, here is how to change the brake light switch out to help us find out what's going on. Check out the images (below). Please let us know what happens.

It's still doing the same thing when you hold down the push button and try to start it says goodbye.

Okay, so is the post above I show you how to do a CAN scan which needs to be done. Please get back to me with the codes so we can fix it and check the battery as well.

I have checked all fuses and relays and all good. I changed the break switch, and it still does the same thing I press the start button on and then I hold it down to start and it goes straight to goodby and that's it, it turns back off and in getting power on the starter but it's not turning over.

Hi,

That's an interesting one. I have a question. You indicated it is getting power to the starter but not turning over. That usually indicates the starter motor itself has failed or the engine is locked.

When you try starting it, do you hear a click at the starter motor?

Take a look through this link and let me know if it helps:

Let me know.

Take care,

Joe

I didn't hear any clicking when I was trying to start it, but the girl who owns the car her boyfriend said a wire the small wire was off the starter and he's putting a new one on it. So, I'll let you know if that works with a new starter. thanks

Yep, this will cause the starter not to work, if this does not make a difference we need to run the codes.
