General Motors has issued a recall for 2009 and 2010 models of the Cadillac CTS. At issue is a potential flaw in the cars' rear suspension, which could result in a loss of steering control.
The issue centers around a wax coating placed on the jam nuts of the rear suspension toe links, which help stabilize the rear wheels. According to a bulletin from the National Highway Traffic Safety Administration, the wax could cause the nuts to loosen, which, in turn, might allow the toe link(s) to separate from the rear wheel. If that were to happen, drivers would have no control over the wheel, which would result in a loss of handling and, potentially, a crash. Owners might be warned of the problem by a "metallic clanking noise" coming from the rear of the vehicle, which could indicate that one or more jam nuts are loosening.
The recall affects 11,147 units of the CTS. GM hasn't yet provided a schedule for the recall, but we would expect it to begin next month. Owners will be able to take their vehicles to a nearby dealer, who will remove all wax residue from the rear toe links and install new jam nuts. (In certain cases, the dealer may even replace the rear toe links altogether.) The repairs will be provided free of charge.
