Well lights arent on when i start my car. so im assuming that means it would be the wiring or a module. I don't care if its a hub as long as my warranty covers it lol. was gonna get front rotors replaced soon anyways. wonder how bad gm will rape me on those, or if i should go to my local auto shop for that. need 4 tires and a rear alignment(idk why its outta wack)
