the abs light comes on,the service traction control light comes on and there is a grinding noise in the front when you brake?

A wheel speed sensor may be failing causing the anti-lock brake system (ABS) to engage when it should not (Grinding noise). A fault code should be stored in the ABS control module. Diagnosing and repairing any stored fault codes should restore normal ABS operation.
Same thing happened to me. Lo and behold ...all the mechanics missed it when my plumber stepdad said hey your break fluid tank is bone dry! He filled it out and amazingly all the lights went out and everything was all well
