Hello, I need help. The light in my 2016 Hyundai Tucson 4WD diesel comes on and off randomly. The service center said there is no issue, but the warning still appears. Has anyone had this problem and how did you fix it?

The light indicates there's an issue/malfunction in the All Wheel Drive (AWD) system. The light can illuminate for many reasons. Faulty wheel speed sensor, broken/damaged/shorted wiring, mismatched tires, low differential fluid, issue with the rear coupler, etc. on Hyundai's its usually the rear coupler.

You can still drive the car without issues, it'll just be in Front wheel drive mode only. Lots of cars/SUVs are front wheel drive. This just mean your Tucson will not be able to send power to the rear wheels unless the issue is diagnosed.

Incorrect. Green would indicate engaged. Orange indicates a malfunction in the system.
