It could be caused by many things without being able to inspect the car it is hard to say. Have the vehicle inspected, it could be uneven tire wear , mis-matched tires, worn suspension components or most likely steering alignment issues. Find a reputable Tire and Alignment shop in your area get them to inspect the vehicle.
