Toyota could be receiving a $16.4 million fine from the National Highway Traffic Safety Administration (NHTSA) for their delay in notifying authorities about problems with acceleration pedals. Additional fines for their handling of the recall and civil suits could add up to millions more. “We now have proof that Toyota failed to live up to its legal obligations,” said Transportation Secretary Ray LaHood. “Worse yet, they knowingly hid a dangerous defect for months from U.S. officials and did not take action to protect drivers.”

Toyota said in a statement that it had not received formal notification from NHTSA about the fine, but that it has taken “a number of important steps to improve communications with regulators and customers on safety-related matters as part of strengthened overall commitment to quality assurance.” The steps include appointing a new chief quality officer.

Under federal law, Toyota has five days to agree to the fine or negotiate a different agreement with NHTSA. If it fails to reach an agreement, it can appeal the fine in federal court.
