GM may soon close the chapter on Chevrolet Volt safety issues, judging by the reaction of the National Highway Traffic Safety Administration's David Strickland. At the 2012 Detroit auto show, Strickland told reporters that automotive safety regulators were satisfied with GM's proposed fixes to prevent Volts from catching on fire, according to Bloomberg.
After an electrical fire started from a Chevrolet Volt three weeks after it had been crash tested by the NHTSA, GM's safety structure tweaks include adding a sensor in the battery coolant system reservoir, adding a tamper-resistant bracket to the top of the reservoir to prevent coolant overfill, and protecting the battery pack with a metal brace. The fixes will be offered free to all current Volt owners and take about two hours to install at a dealer.
"They really did put customers first," Strickland said at the auto show, "This really is a safety issue."
The NHTSA is expected to conclude its investigation soon, just as the Volt enters more markets around the U.S. A total of 7671 Chevrolet Volts were sold on 2011. In NHTSA crash tests, the 2012 Chevrolet Volt was rated an overall five stars (out of a possible five stars), while the Insurance Institute for Highway Safety calls the Volt a Top Safety Pick.
