GM’s 71st recall of the year affects half a million vehicles

General Motors Co said on Friday it was recalling 524,384 cars and sport utility vehicles globally in two actions and would stop sales of two new truck models. The company said it was recalling 430,550 Cadillac SRX and Saab 9-4X SUVs for possible loose joint and worn threads in the rear toe link assembly that could cause the vehicle to wander at highway speed and if it separates, increasing the risk of a crash. GM also said it told U.S. dealers on Thursday to stop selling the newly introduced 2015 Chevy Colorado and GMC Canyon mid-sized pickup trucks in advance of a recall to fix a potential air bag defect.
