Washington Federal auto safety regulators on Tuesday upgraded an investigation into more than 100,000 Chevrolet Corvettes after complaints that the low-beam headlights suddenly stopped working.

The National Highway Traffic Safety Administration said it is upgrading its investigating of 103,374 2005-07 Corvettes to an engineering analysis after reviewing 95 complaints and reports from owners reporting a loss of both low-beam headlights while driving at night without warning. The agency opened a preliminary investigation in May after receiving 30 reports of the problem. NHTSA also received four reports of the issue in 2008 Corvette cars.

In one of the reports, a driver ran over a discarded tire while attempting to pull off the road, NHTSA said. Some complaints said the problem is intermittent and some reported that low-beam function returned after a period of time, typically after the vehicle has been parked. The high-beam headlights and fog lights remain operational, NHTSA said.
