GM said some 2014 models may have flaws in their braking system that could increase the risk of an accident.
The automaker informed the National Highway Transportation Safety Administration that rear brake rotors may have been installed in the front brake system on as many as 8,590 of the two sedan models -- the bulk of them in the United States.
Of these, only 1,694 have been sold to consumers. The rest are on dealer lots around the United States, Canada and Mexico, the company said.
Because rear brake rotors are typically smaller than front brake rotors, the incorrect installation could lead to shortened brake pad life. Over time, this could reduce brake performance.
No crashes or injuries related to the recall have been reported, the automaker said. Customers who already own affected LaCrosses or Malibus will be notified by letter, and may request their dealer supply them with a loaner car while the braking systems are inspected or replaced.
GM is unaware of any crashes or injuries related to the condition. Dealers will inspect subject vehicles and, if necessary, replace the front rotor(s) and front brake pads.
The recall comes as GM faces ongoing investigation from the
, Congress and the Department of Justice into why it waited more than a decade to recall about 2.6 million vehicles to fix an ignition switch defect linked to 13 deaths.
