Toyota executives set an ambitious goal in 2002 to own 15 percent of the global auto industry by 2010, meaning it would surpass General Motors as the world's largest carmaker. To get there, it would have to grow by 50 percent. It would have to build new plants in the United States, China, and elsewhere in Asia, and introduce dozens of new models.
“There was always a question about how fast they could go,” James P. Womack, an author and expert on Toyota’s manufacturing methods, said of the automaker’s growth. “I’m sure they regret that they stomped on the gas so hard.”
Mr. Womack said Toyota was also paying for taking its eye off the message that has been central to its marketing. “When your whole deal was quality, every mistake is a big deal,” he said.
Safety investigators dismissed numerous reports of sudden acceleration, then said data were lacking.
