Fuel gauge reads incorrect when it does come on. Dashboard lights stay off until the tank is on E. Unsafe to drive bc you cannot see your speed. When the dashboard randomly flicks on it will show that it is changing the 2WD to 4WD to 2WD WITHOUT anyone actually moving the switch. I know the dashboard leds are not bad, they come on randomly and they are all present.
