Issa accuses Obama administration of hiding problem with electric car batteries

"The administration has heavily touted that Chevrolet Volt as an alternative technology vehicle that could ‘meet or surpass’ the fuel efficiency targets by 2025," they continued. "In light of the administration’s clear promotion of electric vehicle technology, we are deeply troubled by the fact that the National Highway Traffic Safety Administration (NHTSA) has deliberately suppressed public knowledge of the safety risk posed by the Chevrolet Volt’s lithium-ion battery system.”

Transportation Secretary Ray LaHood has defended the highway safety agency. He told reporters Thursday that it was "absolutely not true" that issues with the Volt were hidden, according to reports, and he has said that the electric cars are safe to drive.
