Toyota Motor Corp faced scrutiny from Congress over its biggest ever safety recall.
House Energy and Commerce Committee Chairman Henry Waxman said he would hold a hearing next month to consider "how quickly and effectively" the car maker responded to complaints about unintended and dangerous acceleration.
"Like many consumers, I am concerned by the seriousness and scope of Toyota's recent recall announcements," Waxman said in a statement.
The unusual action by the U.S. government comes just hours after the Toyota recall for accelerator problems was widened to include China and Europe.
Toyota this week suspended North American sales and production of eight models including its best-selling Camry after pressure from regulators.
Japan's largest company, studied for its devotion to quality, Toyota's recalls on the problems including sticking pedals and slipping floormats could amount to about 8 million vehicles -- more than the number of cars and trucks it sold worldwide in 2009.
Toyota has not released an estimate for the number of incidents of unintended acceleration. Consumer advocates say there are hundreds of such cases in Toyota vehicles.
Meanwhile, Toyota said it was racing to fix one of the recurring problems with sticky accelerator pedals that has forced it to shut down sales and production of most vehicles in the United States.
In consultations with its dealers on Thursday, Toyota said it would take months to complete repairs on the recalled vehicles since it would send notices to affected customers in batches of ten thousand to avoid overrunning repair shops.
CTS Corp the manufacturer of the accelerator pedals that led to the sales half said on Thursday that it has completed work on a redesigned accelerator pedal and was rushing that fixed part into production for Toyota.
Cars sold in Toyota's home market of Japan use accelerators supplied by Denso Corp. Toyota representatives said it was not clear if Denso could supply enough accelerators to help meet the demand surge caused by the U.S. recall. Denso said it was still reviewing the situation and declined further comment. ($1=89.70 Yen)
