General Motors announced Monday that they will recall 3.16 million midsize and large cars to modify their ignition keys to prevent the problem that triggered a recall of 2.19 million U.S. small cars in February and March.

The defect is linked to 13 deaths and 54 crashes in the previously recalled cars.

The recall of the 2000 to 2014 models in the U.S. is because if the key is carrying extra weight and is jarred, the ignition switch might move out of the "run" position, shutting off the engine and disabling the airbags.

That's the same problem involved in the earlier small-car recall.

GM doesn't plan to replace the entire ignition switch in this case, however. Instead, they will use an insert that fills a slot on the head of the key and leaves only a small hole for a key ring.

They say that this will reduce the leverage on the key, making it unlikely to rotate out of "run" if the car hits a pothole or railroad tracks too fast or otherwise has a "jarring road event."
