Sould still be under warranty, difficult to pinpoint w/o a fault code, but a bad ABS sensor will make the esc malfunction. Some cars with a bad brake light switch will cause the problem.
You can try the old standby and disconnect the battery for a period, but you're memory features will be gone.
If it continues you'll need to get the fault code.

Welcome to the Optima Forums.

Congrats on getting your 2017 Optima LX model.

The best thing for you to do is go to your local Kia Dealer and have them run a diagnostic for you.

Without being there, it will be hard to find the issue here in an online forum.

Hope you are able to get it figured out, and hope it's something small.
