The United States government says it intends to impose maximum penalty available on the Japanese Car maker, Toyota over the way it handle the mass recall of its vehicles because of safety faults. US Transport Department is asking Toyota to pay a record fine of 16.4 million dollars for holding back information about faulty accelerator pedals. The department says the company failed to notify it about the flaws in a timely way. The National Highways Traffic Safety Administration said documents provided by Toyota showed the carmaker knew about the defect in September. Toyota has two weeks to appeal against this penalty.
