The Federal Trade Commission is investigating whether some General Motors dealers sold used cars that had been recalled without first repairing the vehicles.
The investigation involves vehicles that were sold as “certified pre-owned.”
Federal investigators are examining whether some of those vehicles were certified for sale even though dealers had allegedly failed to make required repairs.
GM disclosed in a quarterly report filed Thursday that the investigation was underway, and officials with the automaker say they are cooperating fully with the government.
Depending on the outcome, the automaker could face fines, civil consent orders or other penalties.
GM recalled almost 30 million vehicles last year.
