The US government has expanded an investigation into fires that can start in the doors of several Toyota models, adding 600,000 Camrys and other vehicles to the probe.

The investigation now includes 1.4 million cars and SUVs from the 2007 to 2009 model years. When the probe began in February, it involved more than 800,000 Camrys and RAV4 SUVs from 2007.
