General Motors Co. is recalling over 44,000 Cadillac CTS sedans over a flaw that could cause one of the rear wheels to become unstable.

The recall affects 2009 and 2010 CTS vehicles, Cadillac’s best seller.

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.
