It could go to truly no maintenance if I ever get around to fitting a full chain-case to it.
I had IGH on a commuter once. Granted, it was an old 3-speed, but I just didn't find it that useful. The gearing range wasn't very wide compared to the added cabling and weight and annoying rear wheel installation/removal.
Anyway, good luck OP! Hopefully the IGH faithful can help you fix your issue.
It's a set up problem. It's not a maintenance problem. If you set the cable properly, and properly adjust the little nut (tight! and scrape any teflon off the cable, so it doesn't slip. Exactly 100 mm from the end of the housing, make sure the ferule is set in place.) properly, and adjust the cable so the marks line up properly in fourth gear, it should require no adjustment for the life of the cable. A full housing set up is a good idea, as well. This isn't any harder than a derailleur set up, but it's different.
