According to the National Highway Traffic Safety Administration, the vehicles included in the recall may have been equipped with a fractured park lock cable or a malformed steering column lock actuator gear in the lock module assembly. As a result of that defect, it may be possible to shift the vehicle out of park without the key in the ignition or the brake pedal applied, which could increase the likelihood of a rollaway crash.
GM says it has not fielded any complaints of crashes or injuries linked to the recall.
GM will begin the recall campaign on January 17. However, the automaker says most of the vehicles covered by the safety campaign are still on dealer lots.
