General Motors is recalling another 230,000 midsize SUVs due to a potential fire risk serious enough that the maker also is advising owners to park outside until repairs can be made.

The recall expands upon an action GM took last August – that time covering about 250,000 vehicles, including the Chevrolet Trailblazer and GMC Envoy – sold in 20 Snowbelt states. Similar recalls have impacted several other manufacturers, including Toyota, and have so far involved more than 1 million vehicles sold in North America alone.

The problem involves a master power door and window module located in the driver’s door. Over time, moisture can leak in and corrode electrical connections. If that happens, the module can short circuit and overheat. In turn, that can lead to the smell of smoke or, in some instances, a fire.
