Honda Motor Co has agreed to pay $70 million to the U.S. government in penalties for failing to report hundreds of injuries, deaths and other consumer claims involving its cars, transportation officials said on Thursday.

Honda will pay two $35 million fines, making it the largest amount ever paid by an automaker as a result of an investigation by the National Highway Transportation Safety Administration.

The automaker has been under investigation for violations of NHTSA's Early Warning Reporting regulations. The rules require automakers to report quickly any information about possible defects, deaths and injuries or damage and warranty claims made by consumers.
