GM is recalling 788,000 Cobalt and Pontiac G5 sedans for a potentially deadly problem with the ignition system. When the vehicles' keys are connected to heavy key chains (or, say, key rings laden with a dozen extra keys), a sufficiently extreme jolt or impact could shift the ignition out of the "run" position and into the "off" position.
