Chevy Trailblazers' Doors May Do Some Real Trail-Blazing

What is it with these car doors?  Just a few days ago, federal safety regulators said they were opening an investigation of car door fires in 2007 Toyotas.  Now it's the perhaps too-aptly named Chevrolet Trailblazer that's too hot to handle.

The National Highway Traffic Safety Administration (NHTSA) says it has received 12 complaints from Trailblazer owners about the power-window switches melting or burning.

NHTSA is reviewing data for about 309,000 Trailblazers made during the two years at issue -- 2006 and 2007. The Toyota investigation involves more than 830,000 vehicles.

The agency said several of the complaints involved driver door fires, including some that occurred while a Trailblazer was in operation and others during periods when the vehicle was parked.

No injuries or accidents have been reported in any of the incidents. 

The preliminary investigations could eventually lead to recalls of the affected models.
