What causes the dashboard to suddenly go black while driving?

First, check if the vehicle's original fuse has blown, and inspect whether the navigation buttons are stuck, including the RSET button. Switch to a familiar interface and tap the touchscreen to see if it responds. If the touch function works normally, then focus on troubleshooting the display screen itself.

I've been driving for decades, and sudden instrument cluster blackout is a common issue. It's mostly caused by a blown fuse—this little thing protects the circuit and may melt when the engine runs hot for too long. After parking, grab a wrench and open the fuse box under the driver's seat to check if the fuse for the dashboard has turned black or broken. Try replacing it with a new one. Alternatively, it could be poor wiring contact, especially loosened by bumpy roads—inspect if the wire connectors are secure. If the alternator in the engine bay outputs unstable voltage, it might also burn the instrument circuit. I encountered this once before and fixed it by replacing the alternator. Don't panic; getting it checked at a professional shop is the safest approach—safety first.
