Yep years is a good amount of time, they're not actually made to last that long these days.
You know, I was told by Toyota that they consider the warranty period the life of the car. Crazy right?
I've not driven the i30N but have seen them and they look ok. One of my mates is a dealership tech at a Hyundai dealer and he's convinced the Hyundai product is pretty good. The dealership transitioned from Holden to Hyundai for obvious reasons and he didn't previously like the latter. He's now an advocate after working on them.
