Toyota recalls 600,000 Sienna minivans

As congressional investigators dig further into potential electronic problems in runaway Toyotas, the automaker is facing other safety concerns, recalling 600,000 Sienna minivans over rusting spare tyre holders.
The recall Friday came as House investigators said they would hold another hearing in May to review possible electronic problems in runaway Toyotas. The Japanese automaker has recalled more than eight million vehicles because of faulty accelerator pedals, humbling a car company long known for its quality and safety.
Company leaders vowed to respond quickly to the safety concerns.
Separately, Toyota said its engineers in Japan had duplicated the same results of tests that led Consumer Reports to issue a rare "don't buy" warning on the 2010 Lexus GX 460 over rollover concerns. Toyota responded by halting sales of new GX 460s and conducting tests on all of its SUVs.
Lexus spokesman Bill Kwong said the company was evaluating potential remedies for the GX 460 but it was "too early to speculate (on) the details of the remedy and its timing.”
