My info center is telling me to service stability system and my ABS and traction control lights are on. I need to know what to do to fix this because I reset all the codes and started the car and the lights turned back on before I even moved the car. My airbag light is on too but it’s been coming on and turns itself off for a few months now.

The airbag light seems like it will be a separate problem so please start a new question about that. The service stability system and my ABS and traction control lights are probably due to a wheel speed sensor that is not reading correctly which could be due to a front bearing hub that is going out and the sensor has lost connectivity to the reluctor wheel. This video will show you how to see which sensor is bad:

I have left how to change out the ABS wheel sensor and bearing hub in case you need it. Check out the images (below). Please let us know what happens.
