But in the middle of December, on a cloudy day in the middle of the Japanese archipelago's main island, Ron Medford, the acting head of the U.S. agency that regulates auto safety, was reading Toyota executives the riot act.
Medford had been quietly dispatched by the Obama administration to deliver a firm message: Toyota, he told them, had better get its act together, according to U.S. regulators.
By the time Medford arrived in Japan, Toyota was working through a recall that would involve over 5 million vehicles in the United States. The problem was mundane but potentially lethal: floor mats were trapping the accelerator pedal.
U.S. safety regulators had tied five deaths to accidents where that seemed to be the cause, and there were growing doubts about whether the Toyota floormat and pedal design -- a relatively cheap fix -- was the only flaw that needed to be addressed.
Over the prior seven years, the number of U.S. consumer complaints about unintended acceleration in Toyota cars had been steadily climbing, hitting 400 reported cases for the 2007 model year, according to an analysis of National Highway Traffic Safety Administration (NHTSA) data.
But five previous investigations into Toyota opened by NHTSA under the Bush administration had hit a dead end, with no action taken. Two safety probes resulted in relatively cheap floormat recalls by Toyota in 2007 and early 2009. Neither attracted much notice.
