According to the company, the recall is for a fix of the power window master switch on the driver’s arm-rest, which may not operate smoothly or become inoperative. Toyota said that in the worst case scenario, the switch assembly may overheat and melt.
The recall affects certain models built between 2006 and 2010, including the Yaris city car, Corolla small car, Camry and Aurion family sedans and RAV4 and Kluger SUVs.
The firm will recall 2.47 million vehicles in the United States, as well as 1.40 million vehicles in China and 1.39 million vehicles in Europe, making it the biggest single recall since Ford pulled back 7.9 million vehicles in 1996.
Toyota is also currently under fire for apparent engine problems with its 86 sports car, which has been developed in conjunction with Subaru.
Since 2009, Toyota has recalled about 15 million cars worldwide for potential faults including sticking accelerator pedals, floor mats that could trap the accelerator, braking problems, stalling engines, steering defects, fuel leakages, airbag non-deployment and malfunctioning seatbelt buckles.
