WASHINGTON—The National Highway Traffic Safety Administration (NHTSA) said Friday it rejected a petition from General Motors Co. over about 725,000 U.S. sport utility vehicles that do not comply with federal headlight rules. The Detroit automaker argued the issue—a narrow reflection area—did not impact vehicle safety and petitioned NHTSA in 2019 to declare the issue inconsequential for GMC Terrain vehicles from the 2010 through 2017 model years. GM said the issue has been corrected for service parts and does not affect current generation vehicles. NHTSA said in certain weather conditions such as snow and fog the headlight issue could cause “glare to other motorists driving in proximity” to the noncompliant vehicles. By David Shepardson
