Engine Shimmy at Idle

[Roobicon]

I realize calling something a "shimmy" is unscientific, but I'm wondering if anyone has noticed the same. My 2021 4xe has started to, on occasion, "shimmy" when the ICE is on and the vehicle is stopped (at a red light or whatever). It's perceivable through the steering wheel and the car chassis. I use premium gas so I'm (assuming) it's not that causing an engine timing issue. Thanks for reading.

I think I saw a similar thread on here recently. I didn’t follow it but they might have found a solution.

When I read it I was wondering if it might be something to do with weak spark on one cylinder (spark plug or coil?). Seems a bit early for that to start though.
Just speculating.

Hope you get it figured out.
