defect in the car itself,,they all do it sooner or later
Same thing happened with my '05 Cavalier, they tested it at the dealership and it was just bad-had to be replaced, $500 later...
Instrument cluster is going out. I have had this problem it will come and go then stop working and it will move to fuel gage and rpm gage.
