Volt under federal investigation
This is a very strange story and has led to a federal investigation into not only the Volt, but many other cars with lithium ion batteries. The NHTSA conducted a crash test on a Chevrolet Volt not long ago. The car passed the crash test and was placed in a parking lot after wards where it sat with no issue for three weeks.
After sitting for three weeks, the Volt unexpectedly caught fire and the blaze was large enough to damage other cars sitting nearby. The NHTSA investigation is looking at all automakers using lithium ion batteries including GM, Nissan, and Ford. The fact that the car caught fire weeks after the accident raises some serious safety implications.
If the car had been in an owner's possession or had people inside when it caught fire it could have been very tragic. Another Volt has reportedly caught fire while charging and is being investigated as well. So far, no new facts have been offered in the investigation. If the battery packs are found to have a flaw, a recall could do some serious harm to GMs bottom line.
