WASHINGTON (NEWSnet/AP) — General Motors will pay nearly $146 million in penalties to the federal government, because 5.9 million of its older vehicles do not comply with emissions and fuel economy standards.

National Highway Traffic Safety Administration said Wednesday some GM vehicles from the 2012 through 2018 model years do not comply with federal fuel economy requirements. 

U.S. Environmental Protection Agency said analysis shows the vehicles emit 10% more carbon dioxide, on average, than GM’s initial compliance testing claimed. EPA says the vehicles will remain on the road and cannot be repaired.

The enforcement action involves about 4.6 million full-size pickups and SUVs and about 1.3 million midsize SUVs, EPA said. The affected models include the Chevy Tahoe, Cadillac Escalade and Chevy Silverado. About 40 variations of GM vehicles are covered.

GM said it complied with regulations in pollution and mileage certification. The company said it is not admitting to wrongdoing nor that it failed to comply with Clean Air Act.

The problem stems from a change in testing procedures EPA established in 2016, GM spokesman Bill Grotz said.

Owners do not have to take action, because there is no defect in the vehicles, Grotz said.
