The National Highway Traffic Safety Administration (NHTSA) has launched several investigations and issued recalls recently.

The agency has launched an investigation on the 2007-2009 Toyota Camry and Camry Hybrid, 2008 Toyota Highlander Hybrid, 2007-2009 Toyota RAV4 and 2007-2009 Toyota Yaris, all for a possible problem with the power window switches that could lead to overheating of the switch and possibly fire. About 1.4 million vehicles could be affected.

The investigation has been upgraded on some models of the 2006 and 2007 Chevrolet Trailblazer for the possible driver-side door fires. While no injuries or accidents have been reported, NSRA has received 66 complaints the door had melted or burned, as well as 17 complaints of problems with the window switches. 28 of the reports said that the problems led to fires of the driver's door.

Last week, Total Car Score reported on the expanded investigation of the Jeep Cherokee, Jeep Grand Cherokee and Jeep Liberty models that could affect up to 5.1 million vehicles. Now, Center for Auto Safety executive director Clarence Ditlow says that a recall of at least the Jeep Grand Cherokee models is certain, according to a recent interview with The New York Times. The Center for Auto Safety led the push for the NHTSA investigation.

A recall will be issued on these vehicles if the NHTSA investigation finds one is warranted. Consumers who believe they experience a safety issue with their vehicles, tires or a child safety seat can report it to NHTSA by filing a complaint.

The latest recall announcements are:

Honda is recalling some 2012 Honda Civic cars (shown above) for a problem with the driveshaft that could cause it to separate, resulting in a loss of power while driving in any gear or causing the car to roll when in park if the emergency brake has not been set. About 50,000 cars are affected.

Owners of all cars affected by recalls will be notified by mail by the manufacturer. Consumers who are concerned that their car is affected can find more information from the National Highway Traffic Safety Administration by searching for their car here or by calling the toll-free number in their owner's manual.
