From DOT's press announcement:
The U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) today announced that General Motors (GM) has agreed to pay a record $35 million civil penalty and to take part in unprecedented oversight requirements as a result of findings from NHTSA’s timeliness investigation regarding the Chevrolet Cobalt and the automaker’s failure to report a safety defect in the vehicle to the federal government in a timely manner. The defect resulted in the non-deployment of airbags in certain Chevrolet Cobalt and other GM models. This action represents the single highest civil penalty amount ever paid as a result of a NHTSA investigation of violations stemming from a recall.
