I suspect almost everyone who is savvy is already using LLMs instead of Google, I have been for awhile. (If you only read the summary from google and don’t actually click on results links you are also using an LLM)
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.
