The Ford Explorer service light will come on to tell you of a problem. The issue could be minor, or could result in loss of fuel economy, or cause engine failure over time.
could be a broken engine mount
You could have either the 4.0 liter SOHC - V6 engine or the 5.0 liter - V8 engine

could be a bad wire in your engine harness
No, nor could oil in the gas.
My Ford Explorer has seat belts for ( 5 ) people , starting with the 2002 Ford Explorer four door you could get a third row seat so there were seatbelts for ( 7 ) people
