NHTSA Complaint #10641955 — 2014 GMC TERRAIN

WHEN USING LOW BEAM HEAD LIGHTS, OVER HALF OF THE WINDSHIELD ( TOP DOWN) IS BLACKED OUT, CAUSING A RESTRICTED VISION. THERE IS A SLIGHT INCREASE IN VISION WHEN VEHICLE IS BEING DRIVEN ON AN UP HILL GRADE. VEHICLE WAS TAKEN TO THE GMC DEALERSHIP FOR CORRECTION. SERVICE MANAGER DROVE THE VEHICLE HOME AND EXPERIENCED THE REPORTED PROBLEM. SOLUTION TO CORRECT THE RESTRICTED VISION,WAS TO ADJUST/RAISE THE LOW BEAM HEADLIGHTS SO THEY WOULD SHINE HIGHER TO THE MAXIMUM ALLOWABLE BY STATE LAW. THIS ADJUSTMENT RAISED THE BLACK OUT LEVEL BY A VERY LIMITED LEVEL. PROBLEM STILL EXISTS. THIS ADJUSTMENT NOW IS CAUSING ON COMING TRAFFIC AND TRAFFIC WE ARE FOLLOWING TO THINK THAT WE ARE USING OUR HIGH BEAM LIGHTS. CALLED GMC, THEIR REPLY WAS THAT NOTHING COULD BE DONE TO CORRECT THE RESTRICTED VISION. THE PROBLEM IS EXPERIENCED AT ALL SPEEDS. HEAD LIGHT ADJUSTMENT WAS NOT COVERED UNDER WARRANTY. WE NOW HAVE A RESTRICTED USE OF THE VEHICLE FOR DAY TIME DRIVING ONLY. *TR
