The recall affects CTS vehicles from the 2009 and 2010 model years. The CTS is the best-selling Cadillac car.
GM said it would begin to notify owners of the vehicles covered by the recall. Dealers will inspect vehicles under recall and replace a potentially faulty rear toe link.
GM said it expects to have to replace the part on about one in 20 of the vehicles covered by the recall. The automaker said it knew of no injuries or fatalities caused by a failure of the faulty part.
