The National Highway Traffic Safety Administration has decided to extend, for at least another year, federal oversight of General Motors’ decisions and communications about potential vehicle safety issues.

Last year, NHTSA ordered GM to pay a record $35 million civil penalty and to comply with more stringent oversight requirements. NHTSA imposed the tighter requirements following its investigation of GM’s slow response to ignition switch defects in Chevrolet Cobalt cars and other models. The ignition switch defects ultimately led to the safety recall of 2.6 million cars.

Some requirements will continue for an additional two years, NHTSA said in a released statement.

“GM learned a hard lesson last year,” said U.S. Transportation Secretary Anthony Foxx. “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.”
