More Ignition Switch Issues for GM

More troubles for General Motors. The auto maker has announced that it must replace or change ignition keys on about 3.16 million 2000 to 2014 model year cars in the US because the ignition switch may inadvertently move out of the “run” position if the car is jolted by a pothole or crossing railroad tracks, or if the key chain is too heavy. If that happens, the engine can shut down and disable power steering, causing drivers to lose control. The company says the use of a key with a hole, rather than a slotted key, addresses the concern of unintended key rotation, due to a “jarring road event,” such as striking a pothole or crossing railroad tracks.
