Tesla has its problems (between 2019 and 2024 the auto headlights and auto wipers were borderline unusable, now they are merely tolerable, and autopilot is a whole story on it's own), but maintenance is not one of Tesla's issues.
Useable, human-readable errors in the app/touch screen (the car self diagnosed it's 12V battery problem and told me to call a tech) and mobile service is just an awesome experience.
