Federal safety investigators have expanded an investigation launched last week when they initially responded to reports of six fires involving Toyota Camry and RAV-4 models. A similar problem, with fires apparently starting in the driver door of the Chevrolet TrailBlazer, is now being investigated, as well – and authorities want to know if the problems are linked.
The Toyota door fires were apparently linked to defective power window switches and could impact as many as 830,000 vehicles. But, as TheDetroitBureau.com reported last week, the Japanese maker improves its economies of scale by sharing such components in a wide range of products and it is possible still more Toyota vehicles could be roped in by the investigation.
It is also common practice for suppliers to offer similar – and sometimes identical – parts and components to more than one automaker. That could be the case with the 2006 to 2007 TrailBlazer, with 309,000 of the SUVs involved in the latest investigation.
