Considering NX350h for next car, wondering if there are issues that current owners wish they knew before buying?

One thing I saw in a YouTube review is that the windshield wipers have huge gaps in coverage and this can be a visibility problem, especially during snow and slush. Has anyone encountered this?

I’ve also seen that if you don’t drive it for a few days, somehow the battery dies and it’s a big problem? Not sure I understand those complaints but maybe someone can elaborate?

Thank you!!
