The largest recall in Toyota’s 75-year history could undermine the Japanese automaker’s comeback from natural disasters and embarrassing safety problems.

The company recalled 7.43 million cars, trucks and SUVs worldwide to fix faulty power window switches that can cause fires. Wednesday’s recall affects more than a dozen models produced from 2005 through 2010 including the Camry, the top-selling car in the U.S. It’s bigger than the 7 million vehicles recalled two years ago for floor mats that can trap accelerator pedals and cause unintended acceleration.
