Toyota announced Wednesday that it is recalling 6.5 million vehicles worldwide due to defective window switches that could catch fire.
The Japanese automaker has been dealing with the issue since 2009, as this is the fourth recall that the company has announced involving the faulty switches and brings the number of cars affected by the issue to 14 million, according to The New York Times. Additionally, the recall is one of the largest single recalls that Toyota has ever issued.
Finding window switches with the right amount of lubricant grease has been a major problem for Toyota. While the earlier recalls were issued because there was too much heat-resistant grease used to coat the switches' internal mechanisms, the latest recall is about the switches not having enough grease.
Toyota said that this lack of grease could cause the switches to short-circuit, overheat and melt, resulting in a fire, USA Today reported. One report also cited a driver in the U.S. suffering a burnt hand.
At least 11 incidents related to the issue have been reported, according to company spokesman Scott Vazin.
Models covered in the latest recall include the 2009-2011 Corolla, Matrix, Sequoia, Tundra and Scion xB, the 2008-2011 Highlander and Highlander Hybrid, 2006-2011 RAV4, 2006-2010 Yaris and 2009-2010 Scion xD. The 2007 and 2009 Camry and Camry Hybrid are also covered.
Toyota said that out of the total amount of vehicles covered, 2.7 million of them are in the U.S., 1.2 million are in Europe and 600,000 are in Japan, The NY Times reported.
The automaker has been focusing on being more proactive with its recalls ever since it received reports several years ago of unintended acceleration in its vehicles, which lead it to recalling millions of cars in order fix acceleration pedals, floor mats and other parts.
