We have had a problem with the Service vehicle soon and ABS and TRAC off light staying on in my car and I have had several people explain to me that I need to figure out what hub the wires are bad at and replace the entire wheel hub to fix this problem but occasionally my cruise control will give out on me and just not work, nothing consistant. Does anyone know if this problem is related to my other problems or if this would be something completely different?

The best way to figure out which hub/wheel sensor is causing your problem is to have the car scanned with an ABS capable scanner. Also, an inspection can be performed of the wiring to each hub to include the electrical connector. The cruise control problem may be related because when certain abs/chassis/emissions DTCs set cruise control may be inhibited.
