GM is recalling 2012 models of the Chevy Suburban and its sibling GMC Yukon XL SUVs, says the National Highway Traffic Safety Administration.
The recall of 6,159 trucks also covers some 2012 Chevrolet Express and GMC Savanna commercials vans.
The affected trucks have a steering gear pitman shaft that may not have been properly hardened in its manufacture and could break from metal fatigue — leading to steering loss and increasing the risk of a crash.
NHTSA said it would take some months of use for there to be a problem in the new trucks. “There are no reports of crash, injury or property damage; component testing suggests that a fatigue failure due to this condition would not occur for at least five months in service for the most severe usage,” it said in a statement.
GM will notify owners starting April 4, and dealers will replace the affected parts for free.
