2010 g6~ TC button is on, power steering is not working, does it need flyud

Start by checking the power steering fluid level and add fluid if needed. Also check that the belt that drives the system is properly tensioned on the pulley driving the fluid pump. If both appear OK, you will likely need a new pump. As for the CEL and TRAC lights, take the car to a parts store and they will read the codes generating the failure lights. You can then go about fixing the problems identified.
