The U.S. National Highway Traffic Safety Administration is investigating reports of headlight failures in nearly 400,000 Kia Sorento SUVs.
NHTSA say they received 74 reports of sudden, unexpected loss of headlights in model year 2011-2013 Sorentos, including some while drivers were making a turn or traveling on the highway.
Reports say the headlamps sometimes remain dark for some time until they come back on by themselves or the driver turns the vehicle off and then on again; some owners say they have taken vehicles to dealerships for service several times without a permanent fix.
