Following on from the announcement that GM is looking at redesigning the Chevrolet Volt's lithium-ion battery system in the wake of several highly publicized fires resulting from test crashes, comes further news that both the automaker and the National Highway Traffic Safety Administration delayed disclosure of their original findings by months.
Apparently, way back in June, General Motors heard about a Volt fire that happened three weeks after said vehicle was crash tested, yet it wasn't until November that the company, or NHTSA disclosed there was a potential problem, urging both dealers and customers to drain the battery pack immediately following an accident.
As a result the public relations nightmare surrounding Chevy's halo vehicle appears to be deepening, though a good deal of the blame in this case also rests with NHTSA.
Joan Claybrook, a former adminstrator at NHTSA believes part of the reason for the delay was the "fragility of Volt sales." Yet she also believes that "NHTSA could have put out a consumer alert, not to tell them [customers] for six months makes no sense to me."
