Misfire on other Kona years
No other Kona model year has enough reports of misfire for a sheet of its own. See every Kona year.
What this problem usually is
These reports start with the check engine light. Many describe the engine running rough or shaking at idle, a P0300-series code, or a catalytic converter code. A worrying number say the light was flashing. Owners often list ignition coils or spark plugs already replaced, and the light coming back afterward.
What got replaced
Owners who name the part that was replaced mention the spark plugs (4 reports).
Recalls and investigations
One recall on the engine covers the 2019 model year. A recall on the same system isn't always the same failure, so read the defect text.
The piston oil rings may not have been properly heat-treated, which could result in engine damage.

Is this a known problem?
The manufacturer has sent NHTSA 5 service bulletins or notices for the 2019 Hyundai Kona that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.
Hyundai is conducting a service campaign 974 to enhance the knock sensor logic with the Cylinder Noise Diagnostic System (CNDS) software update.

Should you keep driving it?
This page can't tell you that. 0 of 43 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
