Even as Toyota CEO Akio Toyoda wrapped up a tired appearance before (Jongress, the head of the
world's largest automaker wasn't leaving his problems behind.
Toyota faces a criminal investigation by federal lawyers in New York. The company is now being
investigated. Its US dealerships in difficulty now are facing repairs to potentially millions of customer
cars that have been recalled. The company is offering customers money back for rental cars and other
expenses.
Its lawyers are busy preparing to cope with lawsuits. A new hearing will be conducted. And the cost
to Toyota's reputation is only now starting.
Despite back-to-back hearings this week, left to be said were a better explanation for slow actions to
deal with the faults and believable promises that the problems that led to sudden, unintended accelerations
will be fixed.
Toyoda said those changes were being made nearly around the clock, but during three hours of often
tense questions and answers he repeated that there was no link to the vehicle's electronic systems.
Many drivers making complaints against Toyota and the government say their acceleration problems
had nothing to do with floor mat interference (油门踏板故障) or sticky gas pedals (刹车). Outside experts
have suggested electronic problems.
House lawmakers expressed serious criticism on Toyoda, the grandson of the company's founder.
The National Highway Traffic Safety Administration (NHTSA) is seeking records on Toyota's recalls
and is conducting its own review on whether electronics were behind the car faults. NHTSA also continues
to look into steering complaints from drivers of the popular Corolla model.
Toyota has recalled 8. 5 million cars, more than 6 million of them in the United States.
It may be a while before car buyers believe that Toyota really makes safe cars.
Toyota's January sales already fell 16 percent even as most other automakers jumped back from last
year's bad results. Analyst Koji Endo of Advanced Research Japan in Tokyo said he expects February sales,
due out next week, to be down 30 percent t0 40. Toyota's sales problem could continue beyond that.
It will take some time to feel the full effect of this, he said.
