The U.S. National Highway Traffic Safety Administration (NHTSA) has opened two investigations into reports of headlight failures in 392,000 Kia Sorento Sport Utility Vehicles (SUV) and steering issues in 781,000 General Motors vehicles.
Making the announcement on Wednesday, NHTSA said it had received 74 reports of sudden, unexpected loss of headlights in model year 2011-2013 Kia Sorento vehicles including some while drivers were making a turn or traveling on the highway.
Reports allege headlights can turn off for some time until they correct themselves or the driver turns the vehicle off and on again. Some owners complain they have taken vehicles to dealerships for service several times but that the problem returned.
Kia did not immediately comment.
