Steering May Momentarily Lose, then Regain, Electric Power Assist
General Motors will recall 1 million fullsize trucks and SUVs in the U.S. for a potential problem with their electric power steering. The recall applies to model-year 2015 versions of the Chevrolet Silverado 1500, Suburban, and Tahoe; GMC Sierra 1500 and Yukon; and Cadillac Escalade.
According to a recall acknowledgement sent from GM to the National Highway Traffic Safety Administration (NHTSA), the electric power steering system found in GM’s 1/2-ton trucks and fullsize SUVs could momentarily lose steering assist, then regain assist suddenly. This means steering effort would go up for the driver—especially at slow speeds—increasing the risk of a crash. The company says the issue is electrical/software related; since low-speed turns require more electrical assist, the system’s current draw can cause a temporary low-voltage situation, causing the electric power steering to deactivate.
GM dealers have been notified of the problem and will update the electric power steering’s software for free once vehicle owners have been informed of the issue. The company hasn’t announced a notification timeline for vehicle owners. It is estimated that two percent of the recalled vehicles are actually defective. Reuters reports that GM has confirmed 30 crashes related to the recall, with no injuries or deaths.
