it’s not really a surprise this only came up years later, on a typical ev you don’t replace the brake pads (if ever) because it’s the regen braking that slows the car down
the brake pads are only for oh shit moments
tbh i don’t really know of any real maint for a standard ev outside of tyres
That absolutely depends on climate and humidity. The discs will rust, and needs to be maintained by regular usage. And because of that, they will need to be replaced, along with pads.
It’s literally in the owner’s manual for several EVs that the operator is expected to exercise the brakes periodically to prevent rust buildup, particularly when driving in one pedal mode during which one may not be engaging the pads at all.
I’m not disputing that you sometimes can brake to get off rust
but if your brakes are getting rust on them from a lack of use, quite simply you’re not going to be wearing them out to the point they need to be replaced
Brake disks that are rusted will not serve their function as a safety device when it’s needed. Furthermore unused disks can warp, leading to early wear on the pads. Rusted disks absolutely must be replaced, especially in places where seasonal corrosion is commonplace (e.g. in snowy places that use road salt in the winter).

It’s designed for a race track, this is why I said

That sucks. I don’t have much else to add, but I’m impressed you’ve worn out brake pads on a EV so quickly. Hopefully the reason is you’re pushing it hard and having fun! The N looks like a super fun car. I’d love to try one someday.

I’m definitely having fun; the wear is from track weekend visits (where the I5N holds its own amongst everything from muscle cars to Porsches). When the track weekend is over, it magically becomes a practical hatchback.
I can’t even imagine buying a track car that you can’t change brake pads on… I used to do track days with my daily driver back in the day, and would usually swap pads at least twice in a weekend (street to track, and back to street) I could do all 4 wheels in under 30 minutes in the paddock, no big deal.
At some tracks I could kill a set of new street pads in 2 days. So I started switching to track compound pads, which held up to high heat and repeated heavy braking much better - but those were terrible when cold, really had to be warmed up to work properly, so they were to the point of being dangerous to drive on the street.
And that was with a sub-3000 lbs car. The Ioniq 5 N is almost 5000 lbs, it must be absolute murder on pads.
yeah it’s absolutely mental hyundai have done this tbh, I do wonder since there is so little maint to do on EV’s whether it’s an attempt to throw their service centres/dealerships a bone… but damn does it come off as silly

you think a once a month at worst brake pad test will wear out a pad to the point it needs to be replaced?
if this was true petrol cars world be replacing their brake pads every month
a lot of ev’s now also blend braking, low speed braking is brakes, above 5kph is regen

You will fail the yearly inspection here if there is too much rust on your brakes.
Also, at some point that rust will cause grooves in your brake rotor and they need to be replaced.

Ok thanks, but this is not a common issue for EV drivers
These are things I know from first hand experience. Talk to any EV mechanic in Canada, they will tell you the same thing.
feel free to provide the stats on how many brake pads for ev’s are being replaced every day
Actually, it is.
Should be doing it every day to keep the rotors clean.
Then why is this dude changing his brake pads?
Look at what type of EV it is
