Toyota is calling back 7.43 million vehicles worldwide because of possible defective driver's side power window switches that could emit smoke.

The recall reportedly covers 2.5 million units in the U.S., 1.4 million units in China and 1.39 million in Europe.

Toyota blames the malfunction on an uneven application of grease on the switches, for which it has received 200 complaints in the U.S. The auto maker says owners of the affected models may experience a notched or sticky feeling during switch operation.

The recall affects some of Toyota's best-selling models, including the Camry midsize and Corolla compact sedans and RAV4 small and Highlander midsize CUVs.

All affected models were built from 2005-2010, Toyota says. The Camry, Toyota’s best-selling car, represents 938,000 of the 2.5 million units being pulled back in the U.S.

The latest move is the No.1 Japanese auto maker's largest recall since 2009-2010, when it called back more than 7 million cars and light trucks due to possible unintended acceleration.

Toyota says recall notices for the window switch will go out in late October, and the repair will take about an hour at a dealer.
