2012 Kia Optima

Low Tire Pressure light on, Traction Control light on, brake lights don’t work 90% of the time, the other 10% they do. When they’re working, the Traction Control light is off. Just replaced the Brake Light Switch, didn’t fix the problem. I’m thinking TPMS sensors or Wheel Speed Sensor? I don’t know which direction to go and I don’t want to keep spending money on things that I don’t need.
