Can a car be restored to factory settings?

Car can be restored to factory settings. Here are the relevant details: 1. Factory settings: This means restoring to the default state when the car left the factory. For example, the start interface, standby mode, operation shortcuts, timer reminders and other functions will be restored, and saved parameter settings will be cleared. 2. During factory reset: Audio-video settings such as voice volume, display resolution, screen sensitivity, voice type, etc. will all be restored to factory settings. At this time, users need to reconfigure personal settings according to their usage habits. In addition, settings related to the navigation system's hardware and software, such as input methods, navigation map loading paths, memory card paths, map versions, operating system versions, etc., as well as later upgrade sections, will return to the original factory state, requiring subsequent reconfiguration and upgrades.
I've been driving a Hyundai for almost ten years, and I always have to explain this clearly when friends ask about it. Cars don't have a factory reset button function like phones or computers. What you can do is a partial electronic reset: for example, disconnecting the car battery for a few minutes can clear the infotainment screen settings or error light codes, making the car feel a bit like it's been reset. But this only affects the software part; hardware such as engine wear, tire lifespan, or brake fluid aging remains unchanged and can't return to the factory state. I suggest not messing around with it yourself—it's unsafe and could damage the circuits. If you really want to clear fault memory, use an OBD-II scanner tool to connect to the port and clear the codes. But ultimately, the changes accumulated during the vehicle's operation can't be completely undone. Regular maintenance is much better than wishing for a reset, and if there's an issue, it's more reliable to visit the 4S shop.
