According to the National Highway Traffic Safety Administration, GM is recalling 2012 models of the Chevy Suburban and the GMC Yukon XL. The recall also covers 2012 Chevy Express and GMC Savanna commerical vans. The affected vehicles have a steering gear pitman shaft that possibly did not properly harden in the manufacturing stage and could break from metal fatigue. This break could lead to steering loss and increases the risk of a serious accident.
The report from the NHTSA says that it could take some time for the problem to occur in new trucks; "component testing suggests that a fatigue failure due to this condition would not occur for at least 5 months in service for the most severe usage."
GM will begin notifying owners starting April 4, 2012 and dealers will replace the affected parts free of charge.
