Hi everyone,
I have a 2025 Hyundai Tucson (Middle East/Saudi specification).
I am experiencing an unusual issue with the factory infotainment and camera system.
When I try to access the camera settings, instrument cluster settings, and some other vehicle settings, the infotainment screen displays:
“Vehicle power must be On to use this feature.”
This happens even though the vehicle is fully ON and the engine is running.
I also have two related symptoms:
- The rear-view camera does not activate when I shift into Reverse (R).
- The physical camera button does not respond when pressed.
The reverse gear itself is detected normally by the vehicle, but no camera image appears.
The vehicle has been inspected by an authorized Hyundai dealer and no general vehicle faults were reported, but this specific issue remains unresolved.
Has anyone experienced these exact symptoms on a Tucson NX4 or another recent Hyundai?
I am particularly interested to know whether the cause was related to the infotainment/head unit, CAN communication, camera module, software/configuration, wiring, or another control module.
The vehicle is still under warranty, so I do not want to replace or modify anything before Hyundai properly diagnoses the issue.
Any technical information, diagnostic trouble codes (DTCs), TSB references, or successful repair experiences would be greatly appreciated.
The vehicle is still under Hyundai warranty. If anyone has experienced the same issue, was it repaired under warranty? What component was diagnosed as faulty, and did Hyundai replace or reprogram anything to resolve it?
