This has nothing to do with EVs, and likely all new Hyundais do (or will?) use this same diagnostic system.
For comparison, Teslas do not require purchase of their software for basic maintenance, the service mode that is accessible to the user is amazing, has so many diagnostics tools available for free.
Oh and by the way, from my experience Teslas don’t ever need brake pads replaced unless you are taking the car to the track. I suspect the same is true for most other EVs.
So you end up with two diverging discovery layers: Google, increasingly polluted by cheap AI content, and LLMs, which seem to weight structured data, documentation quality, and mentions on high-trust platforms (Reddit, GitHub, Stack Overflow) way more than traditional SEO signals.
The real question is whether Google fixes this before users just default to asking ChatGPT instead of searching.
