GV70 2026 rough idle at startup

I've had a gv70 2026 4. Cylinder sport prestige model for about 6 months. It's frustrating in that I've had a issue with rough idle at startup until the initial fast idle slows pretty much since the day I bought the car. It's been into service and they've run all their tests and say it's just normal. But they walked me out and had me start up a few other similar models and I didn't feel it on any of them. Is anyone else having this kind of issue?
