Security concerns aside, IMHO this is more of an intelligence hurdle so people who can jump that are smart enough to not bodge this simple but very critical repair. To put simply: If you aren’t a professional auto repair shop with ODB-Tools, just know that these parking brake servos are self-adjusting.
Hyundai is also not the first one with these restrictions, lots of manufacturers have quietly implemented such hurdles everywhere in cars, especially Stellantis.
Also with “super cars” like the Ioniq 5 N (specifically the N variant) meant for rich guys, you usually don’t care about repair. You just pay the dealer for that. For comparison look for repairability in high-priced cars like some Ferraris, Porsches, Mercedes, BMW, Audis, etc. It’s a shit show all the way in the high-price terrain. Except Stellantis is doing this in the low-price range as well now. God I had Stellantis. Never again.









That one time I bought a pair for a joke at a party a few years ago, I just searched on Amazon for high heels in my regular male size. Apparently, some chinese companies custom-make large-sized lady boots on demand this way. I think I ordered them from “Only Maker”, their models seemed to be safe to walk in with wide heels… I checked before whether you need to order a different size - turns out there is no significant difference. Simply order whatever standard size you usually buy. Just make sure that you pick a model with a wider front. Male feet tend to be wider there, which cause the majority of problems when walking. This is especially true if you have issues with normal shoes being a bit narrow in general (like rubbing at your outer toes when walking for a while).
Also remember that high heels tend to be in the category of “sitting shoes”, not “walking shoes”. I learned that at said party fairly quickly.
