Open the full vehicle complaint log (all categories)THE HEADLIGHTS ON MY NEW GMC SIERRA 2500HD DENALI ARE HORRIBLE AND UNSAFE FOR DRIVING AT NIGHT. THE 25 WATT RATING AND 2,000 LUMENS ON THE OEM HID BULBS DO NOT PROVIDE ADEQUATE, SAFE LIGHTING FOR OPERATING MY VEHICLE. I ALREADY HIT A DEER WITH MY BRAND NEW TRUCK BECAUSE I COULDN'T SEE IT WELL ENOUGH IN ADVANCE OF THE COLLISION. GMC SHOULD BE HELD ACCOUNTABLE FOR PUTTING SUCH A LOW POWER, POOR QUALITY AND UNSAFE HEADLIGHT IN THEIR $70,000 VEHICLES. I'M RENTING A HYUNDAI WHILE MY TRUCK IS BEING REPAIRED AND THE HEADLIGHTS ON THIS $30,000 FOREIGN CAR ARE 10XS BETTER THAN THE ONES ON MY TRUCK. WHY?
HEADLIGHT ON THIS TRUCK ARE EXTREMELY HORRIBLE AND UNSAFE AT NIGHT TIME. THE LIGHT OUTPUT IS WORST THEN ANY OTHER VEHICLE I HAVE EVER DROVE. GM NEEDS TO STAND BEHIND THE ISSUE AND PROVIDE A SOLUTION
