potentially circumvent possible failure later on. Seems relatively straightforward for a tech to do. I have a place nearby that I had a good experience with on my daughter's Prius. Been building a cart with the needed items including:
Oil (specific brand/type)
Replacement magnetic cap (factory cap is not magnetic, magnet reportedly helps remove particles that may form)
Also adding a cabin air filter and some WD-40 Silicone spray to do standard lubricant of hinges, etc.
I never really took much personal initiative with car maintenance outside of normal stuff but because the EV needs so little dealer maintenance, I'm inclined to do more stuff myself. This gear oil change may be extraneous but it seems it should run me < $100 total.
Linked video has a guy discussing (UK) what he's done. I read extensively on some Kona/Niro EV forums last night about multi-year observance of this potential issue and mechanically inclined users collecting data from multiple owners.
