Earlier this week the National Highway Traffic Safety Administration announced an investigation into fires occurring in two vehicles in Toyota's line of car models. Affected are the crossover RAV4 SUV and the popular Camry. Both vehicles are found throughout the state of Pennsylvania.

This is certainly not the first time we have written a post having to do with a car catching on fire due to a product defect. Generally however, those fires are located somewhere under the hood, usually related to the engine. In this case, the fires are occurring in the vehicles' doors.

More specifically, the fires have occurred in the driver's side doors of 2007 RAV4s and Camrys. So far, a total of six fires have been reported. Thankfully, none of them resulted in any injuries.

This past summer, the owner of a RAV4 traded the SUV in after a hole was burned in the door when a fire started in the master power window switch. That owner indicated that the trade was necessary, despite the vehicle having been paid off, out of fear that the car would again start on fire.

In another instance, a Camry was destroyed after flames appeared shortly after the car was started.

In total, the investigation, which also includes the Solara, could reach to include around 830,000 cars. Though more than 14 million Toyota vehicles have been recalled over the course of the past three years, as of yet, no recalls have been issued in this instance. We will continue to monitor the story and provide updates as they become available.
