EXTERIOR LIGHTING: THE HEAD LIGHT LOW BEAMS ON THIS VEHICLE ARE INFERIOR AND A SAFETY HAZARD. THEY DO NOT ILLUMINATE FAR ENOUGH IN FRONT OF THE CAR AND ARE NOT BRIGHT ENOUGH. I HAVE HIT SEVERAL CURBS AT NIGHT JUST BECAUSE YOU JUST CAN'T SEE THEM GOING AROUND CURBS OR AT INTERSECTIONS WITH THE LIGHTS ON THIS SUV. TALKED TO DEALER ABOUT REPLACEMENT WITH AUTO PART STORE HEADLAMPS, AND THE RESPONSE WAS IT WOULD VOID WARRANTY ON THE HEAD LIGHTS (BREAK THE SEAL) AND WOULD COST SEVERAL THOUSAND DOLLARS. AND WOULD NOT IMPROVE THE LIGHTING. LIKE OTHERS, I DRIVE WITH MY HIGH BEAMS ON, EVEN IN THE CITY SO I CAN SEE PEDESTRIANS AND CURBS. GM SHOULD RECALL THESE HEADLAMPS AND REPLACE FOR FREE BEFORE PEOPLE START GETTING KILLED.
