GM recalls additional 3.1M cars

General Motors is recalling more than 3 million additional cars and it's all related to that ignition switch problem that the company first identified back in February.

GM admits the issue caused at least 54 crashes and 13 deaths in smaller cars and had already led to the recall of 2.6 million other cars in February. Most of the cars involved in the new recall are older models.

GM said they need to urgently rework the keys. The cars came with a key that has a big hole or slot. If that key is carrying too many other keys and gets jostled, it can bump the ignition switch to the "off" position. To fix it, GM will fill the slot and replace it with a simple hole that won't carry extra keys.

"Losing power steering, power breaks, airbag, even the stitching up of the belt - that is serious, and it not only can cause a crash, but it can result in more injury if a crash occurs," said Joan Claybrook, a former National Highway Traffic Safety Administrator.

This latest recall comes just two weeks after GM CEO Mary Barra said the results of an outside investigation into the original defect had found a pattern of "incompetence and neglect" at the company.

"We simply didn't do our job," Barra said June 5. "We failed these customers, and we must face up to it and we must learn from it."

GM acknowledges it failed to order a recall for 10 years while customers died in cars that had the original defect. The company insists the culture at GM has changed and it will take a very aggressive approach to all safety issues.

So far this year, the company has recalled 20 million vehicles worldwide. That's roughly the same number of cars it sold in the U.S. since 2006.
