Toyota Motor Corp. and other major automakers were sued Wednesday in a California federal court over "deadly" keyless ignition systems that are linked to serious injuries and more than 13 deaths in the United States.

The class action complaint says drivers, used to traditional keys, have unknowingly left their car running in their garage and filled their home with deadly carbon monoxide gas, such as a 29-year-old woman who died in 2010 when her 2006 Lexus IS 250 was left running.

In cars with the keyless ignition system, drivers can start and turn off the car with the push of a button while an electronic key fob is nearby.
