Sarurn Hybrid Traction Control

Daughter has a 2007 Saturn Vue Hybrid, 4 cylinder, automatic. Traction control engages inappropriately, basically on all the time. Dash switch will not turn it off. Traction Control puts drag on car, kills gas mileage and disallows car to go into ‘Economy Mode’.
Any ideas as to why this happens would be greatly appreciated.
Also, is there a way to disable Traction Control/ABS for the time being in order to eliminate the drag?
Thank you.
