US DOT extends federal oversight of General Motors

General Motors isn't out of the woods with the federal government, yet.

To track General Motors' (GM) progress on investigating potential safety issues, the U.S. Department of Transportation's National Highway Traffic Safety Administration (NHTSA) has planned to extend federal oversight over GM for another year, the NHTSA announced Thursday.

The extension—presented to GM in a letter dated May 14—requires GM to continue to report all safety-related issues to the NHTSA and meet with the agency regularly.

The renewal of the consent order allows NHTSA to review GM's decision-making and communications about possible vehicle safety threats. Last year, the company agreed to pay a record $35 million civil penalty and allow unprecedented oversight following its failure to report a defect in its Chevrolet Cobalt model, leading to non-deployment of airbags in certain Chevrolet Cobalt and other GM models.

Last year the company recalled nearly 30 million of its cars.

"GM learned a hard lesson last year," said U.S. Transportation Secretary Foxx, in the statement. "We expect to see the improvements they've made continue and that their new approaches are applied to every GM safety issue and every recall. Today's action will help keep them on the right track."

NHTSA extended its order from last year since it proved effective in addressing motor vehicle safety defects, according to the press release.

GM was not available for a comment.
