In owners’ own words

Exterior lighting mileage not reported 5 mo in service
VEHICLE LOW BEAM HEAD LIGHTS HAVE VERY POOR COVERAGE AND BRIGHTNESS. WHEN DRIVING AT NIGHT THEY BARELY LIGHT THE ROAD IN FRONT OF THE VEHICLE. COVERAGE SIDE TO SIDE IS VERY WEAK. ADDITIONALLY WHEN IT IS RAINING OUT, IT IS LIKE DRIVING WITH NO HEADLIGHTS ON AT ALL. I HAVE CONTACTED THE DEALER AND THEY HAVE INDICATED THIS IS COMMON COMPLAINT ON 2014 SIERRA 1500S AND ALL 2015 SIERRAS SINCE THE LAST REDESIGN.
Exterior lighting 10 mi 9 mo in service
THE HEADLIGHTS DO NOT PROVIDE ADEQUATE LIGHTING OF THE ROAD WHICH MAKES IT VERY DIFFICULT TO DRIVE SAFELY AT NIGHT . I HAVE TRIED TO WORK THROUGH GMC THEY CHANGED THE BULBS TO A DIFFERENT VENDOR BUT DIDN'T HELP. GMC NOW IN THE 2016 ARE USING HID BULBS THEY ALSO USED A DIFFERENT LIGHTING SYSTEM IN THE 2014 . THE LOCAL GMC DEALER AGREES THAT THE LIGHTING COULD LEAD TO POSSIBLE ACCIDENT . THE LUMEN OF THE BULBS ARE DOWN AROUND 1200 WHICH IS HALF OF THE NORMAL LUMENS TO PROVIDE ADEQUATE STOPPING OR VISUAL OF THE ROAD. PLEASE HELP US OWNERS AS THIS VEHICLE IS VERY DANGEROUS TO DRIVE AFTER DARK. *DT
Exterior lighting mileage not reported 9 mo in service
