All owners of the 2011 Chevrolet Volt and some of the 2012 model will soon be notified by GM to replace their 120-volt charging cords with new ones after certain consumers complained about overheating problems.

GM spokesman Randal Fox told Reuters that he did not know the total number of the vehicles affected, but said it was fewer than the 11,000 or so Volts sold so far in the States. He also made a point to note that this was not a safety recall.

“It’s just an effort to offer a more consistent charging experience. It’s not a safety recall. It’s more of a customer-satisfaction program,” Fox said.

“We made some enhancements to the design to add some durability and reliability. For example, GM increased the cord’s cable size to enhance durability,” he added.

In most cases, Volt owners will receive the new cords when they bring their cars in for the battery enhancement’s to address safety concerns over fires, according to Fox. He added that the new 120-volt cords will not change recharging time and the swap does not involve the 240-volt cords.
