DETROIT — The largest recall in Toyota's 75-year history could undermine the carmaker's comeback from natural disasters and embarrassing safety problems.
The company on Wednesday recalled 7.43 million cars, trucks and SUVs worldwide to fix faulty power-window switches that can cause fires. The recall affects more than a dozen models produced from 2005 through 2010 around the world 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.
The problem centers on the power window switch, which is inside the driver's door and controls when a window is opened or closed. Toyota said grease wasn't applied evenly to the switch during production, causing friction and sometimes smoke and fire.
The flaw raises questions about whether Toyota Motor Corp. has solved quality and safety issues that embarrassed the company in 2009 and 2010. It also could jeopardize Toyota's impressive rebound from last year's earthquake and tsunami in Japan. Those disasters hobbled factories and left dealers short of models to sell.
The Toyota recall "takes some of the sheen off its recovering brand image and should have a financial impact," Standard & Poor's analyst Efraim Levy wrote in a note to investors. Toyota's U.S. shares fell $1.60, or 2.1 percent, to $74.46 Wednesday afternoon.
Toyota said initially the window switch problem hasn't caused any crashes or injuries. But documents filed by U.S. safety regulators show customers have reported 161 fires and nine injuries. No deaths have occurred.
The U.S. National Highway Traffic Safety Administration began looking into window switch problems with two Toyota models in February after noticing a higher than normal number of complaints. Most fires caused by the window switch were minor, although a Camry was destroyed in one case. Several owners reported that they were afraid to drive their vehicles because of the threat of fires. NHTSA said Wednesday the investigation remains open pending a review of recall documents.
Toyota said Wednesday it has received more than 200 complaints about switches in the U.S., and more from other countries including 39 in Japan. Most of the complaints were about a sticky feel to switches while pushing the button to move the window up or down, but there also were complaints of the smell of smoke, company spokesman John Hanson said.
Toyota dealers will inspect the switches and apply a special grease to them. In some cases, the switches and circuit boards could be replaced, Hanson said. Some repair shops might have used off-the-shelf greases to fix the problem, but those eventually will make it worse, he said.
The recall includes 2.5 million vehicles in the U.S., where it covers about half the models sold under the Toyota and Scion brands.
