General Motors is trying to square up after 5.9 million of its older vehicles

The automaker will pay nearly $146 million in penalties to the federal government but it is not admitting any wrong doing. The National Highway Traffic Safety Administration said certain GM vehicles from the 2012 through 2018 model years did not comply with federal fuel economy requirements. The fine comes after the EPA said testing showed the GM pickup trucks and SUVs emit 10% more carbon dioxide than GM's initial compliance testing claimed. GM said it did complied with all regulations in pollution and mileage certification of its vehicles.
