Misfire on other Elantra years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2015, 2016, 2021, 2022.
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 ignition coils (39 reports), the spark plugs (12 reports), the sensor (12 reports) and the catalytic converter (3 reports).

Is this a known problem?

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.

“The vehicle has stalled at low speeds multiple times. No check engine light comes on, so my mechanic canât diagnose anything. He suspects itâs the issue that many other model years have been recalled for, but the 2017 Elantras are not included in the recall. Most recently the car stalled as I came to a stop at a red light.”

About 5 weeks ago while my 17yr old son was driving the motor died in the middle of the road and began knocking. No check engine light or anything.

Should you keep driving it?
This page can't tell you that. 1 of 114 reports involved a crash and 1 people were hurt. 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.
