BURLINGTON, WI (WTAQ) - Government crash testing has produced a fire in the new Chevrolet Volt.

The testing was brought on by a series of fires first reported from a test facility in Burlington six months ago. That electric car caught on fire while it was being stored in a parking lot.

The fire started about three weeks after the car had been put through a side-impact crash test.

General Motors issued a statement Friday saying the Volt “doesn’t present undue risk as a part of normal operation or immediately after a severe crash.”

The National Traffic Safety Administration is investigating the safety threat from the Volt’s lithium-ion batteries.
