How to tell if LKAS needs recalibration or repair?

[Kon]

I keep reading all these posts about people letting their Lane Keep Assist do the driving for so long that they start to get warnings about keeping their hands on the wheel. It makes me wonder if my LKAS is either poorly calibrated or broken.

Even in Pre-Departure mode on straight roads with very clear lines, my Genesis wanders significantly within the lane. I often have to intervene to keep it from crossing the line (or wandering so much that I look like a drunk driver). My commute is on a recently repaved/repainted highway with extremely gentle curves but the LKAS can't navigate any of them on its own.

I'm sure this system is covered by the warranty, but how do I know if it's actually broken or if it's working as intended?

Pre-departure is ping-pong mode. It wanders significantly. If you do Post-departure you'll get less wander but get much closer to the lines.

Shouldn't it be the other way around? Post-departure should wander much more since it doesn't do anything until it thinks you've crossed a line.

I've tried both settings and it wanders in both. I have tried letting the car "drive itself" on different roads when I was bored and there wasn't any traffic. The car did okay but it's no substitute for hands on the wheel and eyes on the road. I do find the system nice on long drives, but for every day driving, I turn it off. It just annoys me in curves when I'm doing fine but the car thinks it knows better ;-)
