Something amiss with Volt battery packs after crashes
I mentioned a couple weeks ago that the NHTSA had a Chevy Volt catch fire in the parking lot of its testing facility three weeks after the crash test was conducted. That fire prompted a security investigation in the Volt and other EVs due to the risk of fire from ruptured battery packs. The crash testing of the Volt involved three more vehicles with two of them having some serious issues.
All of the vehicles were subjected to side impacts that simulated a strike with a narrow object like a pole on the side of the car and then a roll over. The cooling lines were damaged in all three impacts. One of the cars showed increased heat the day after the test, but never a caught fire.
The second Volt was monitored daily and caught fire at the test facility seven days after the accident. The third Volt immediately started to smoke and throw sparks. The testing is still ongoing on the Volts and if the investigation finds a fire hazard resulting from a crash the implications for GM and the Volt are very serious.
