General Motors recall number 11029 involves 50,000 model year 2009-2010 Cadillac CTS vehicles, 11,147 of which are in the U.S., that may experience an inboard or outboard turning of the rear wheel. No, this is not an extra feature, but rather an crash risk not to be taken lightly.
The problem is caused by a wax coating on the rear suspension toe link jam nuts that may allow the nut (or nuts) to loosen. If enough loosening occurs, the toe link could separate — resulting in the inward and outward turning of the rear wheel that would (naturally) lead to a loss of control and unexpected changes in handling — increasing the risk of an accident.
Before that occurs, however, owners may hear a noticeable clanking noise emanating from the rear of the vehicle, forewarning them of the loose nut. The issues will be fixed free of charge, with dealers being instructed to either clean all wax residue from the rear suspension toe link and install two new jam nuts or replace the rear suspension toe link altogether.
So far, no accidents have been reported as a result of the defect and GM hasn’t provided an owner notification schedule, but owners can contact Cadillac at 1-866-982-2339 and the GM Owner Center at www.GMOwnerCenter.com
