I have the SS model. My service traction control light is staying on, along with the ABS light. It makes a grinding sound along with vibration every once in while, when you hit the brakes. I put new brakes on the back and front. Checked all the fluids. I even hooked it up to a computer. It has 53,000 miles, with a V6. I still cannot find the problem. help

Check and see if the hub assembly is not bad. The speed sensor is built in to the assembly. The sensor goes bad, leading for the ABS/traction control to activate and always stay on in the info center in the car. Hope this helps. I had the a similar problem has to replace to hub due to the bad sensor.

Here is a video to help you to tell which sensor and hub is bad:
