GM says the recall affects more than 44,000 CTS vehicles in the United States from the 2009 and 2010 model years. The remaining vehicles were sold in China and around the globe.
GM says there have been no injuries or fatalities related to the recall.
The auto company said nuts in the rear suspension could become loose, causing a sudden change in the vehicle's handling or making the driver lose control of the vehicle.
