Officials testified about the U.S. government response to the Toyota recalls of vehicles due to break and acceleration issues. In his testimony, Secretary LaHood promised a complete investigation into reported incidents of sudden, deadly spikes in speed and said he may call for all new U.S. vehicles to have brakes that can override their accelerators. He also vowed to tell Japan during an upcoming visit that U.S. regulators have treated Toyota more fairly than their Japanese counterparts treat U.S. beef.
