DETROIT — Federal safety regulators are investigating fires in the driver’s-side doors of Chevrolet TrailBlazers, the second such probe in a week.
The latest inquiry involves more than 309,000 TrailBlazer SUVs from the 2006 and 2007 model years. The fires began in the power-window switch or related electrical parts, the National Highway Traffic Safety Administration said Monday.
The agency opened the first probe last week into similar problems with the 2007 Toyota Camry and RAV4. The TrailBlazer probe began Thursday.
None of the vehicles has been recalled.
The TrailBlazer, phased out in the U.S. in 2009, was among GM’s top sellers. The Camry was the best-selling car in the U.S. in 2007 and last year.
The agency has received 12 complaints of smoke or fires in TrailBlazers. No injuries have been reported, said the SUV’s maker, General Motors. None of the vehicles that caught fire was destroyed, although some door parts melted and seats were singed, the automaker said.
Several of the TrailBlazer fires happened while the SUVs were moving. Others occurred when the engines were off and the vehicles were unattended.
An NHTSA spokeswoman said the agency is in the process of finding out if GM and Toyota got switches from the same parts maker, and if any other vehicles had them.
Neither GM nor Toyota would identify its parts-supply company.
