Toyota announced last Wednesday that it is recalling about 6.5 million vehicles worldwide to fix an issue related to the driver's side power window master switch that could lead to fires.

According to Toyota, the power window switch in the recalled vehicles may have been manufactured with insufficient lubricant grease. If enough grease isn't applied, the switch may develop a short circuit that can cause the switch assembly to overheat and melt. A melting switch can produce smoke and potentially lead to a fire, Toyota said.

The vehicles involved in the recall are as follows:
2007 and 2009 Camry and Camry Hybrid
2009-2011 Corolla
2008-2011 Highlander and Highlander Hybrid
2009-2011 Matrix
2006-2011 RAV4
2009-2011 Sequoia
2009-2011 Tundra
2006-2011 Yaris
2009-2011 Scion xB
2009-2011 Scion xD

Toyota previously issued a recall for this problem in 2012 when it had to repair 7.5 million vehicles globally from the 2007-2009 model years, including 2.5 million in the US. These latest models had the grease applied in a different way.

A Toyota spokesperson said. "We have 11 reports where part of the door trim and/or switch was burnt. There was one incident of someone in the US getting a burn to the hand from this issue The company isn't aware of any crashes from the problem, though."

The recall includes about 2.7 million vehicles in North America, 1.2 million in Europe, and 600,000 in Japan.
