THE BRAKE LIGHTS IN THIS VEHICLE ARE FAULTY. MY DRIVER SIDE WENT OUT IN JULY AND IN THE SAME MONTH MY PASSENGER SIDE WENT OUT. THE BULBS ARE NOT BURNED OUT AND IT HAS TO DO WITH THE WIRING. GMC WILL NOT COVER THE SECOND LIGHT OR PROVIDE COST ASSISTANCE BECAUSE I AM OUT OF WARRANTY DUE TO MILES.

VEHICLE WAS MANUFACTURED MID 2014, 2015 MODEL, CURRENTLY HAS JUST OVER 52K MILES. DRIVERS SIDE TAILLIGHT IS BEING TEMPERAMENTAL; NO WARNING LIGHTS INSIDE TO INDICATE A FAILURE.
