If the traction and ABS light are coming on, it is setting a code that would directly relate to a fault. It would require a scan tool to extract the codes, it would be a guess at this point as to what is causing it, there are many possibilities. There are a couple bulletins regarding front wheel bearing issues with your vehicle, and a special policy campaign if yours fits the criteria. Here is that info.
