DETROIT — General Motors Co. said Monday it is recalling 1.5 million vehicles worldwide because the electronic power-steering assist can suddenly stop working, making them harder to steer.
The new recall brings to 6.3 million the number of vehicles GM has recalled since February. The initial recall — now at 2.6 million small cars for an ignition switch defect — prompted the automaker to name a new safety chief and speed up the review of cases that might lead to recalls.
GM said it expects recall-related costs to total $750 million in the first quarter, including $300 million for the ignition switch recall.
Included in the new recall are: Chevrolet Malibu from the 2004-2005 model years, plus some 2006, 2008 and 2009 model-year cars; Chevrolet Malibu Maxx from the 2004-2005 model years, plus some 2006 model-year cars; Chevrolet HHR from the 2009-2010 model years (non-turbocharged only); Some Chevrolet Cobalts from the 2010 model year; Some Saturn Auras from the 2008-2009 model years; Saturn Ion from the 2004-2007 model years; Pontiac G6 from the 2005 model year, plus some cars from the 2006, 2008 and 2009 model years.
GM dealers will replace the power steering motor and other parts for free.
GM also said it will recall almost 500,000 late-model pickup trucks and large sport-utility vehicles to fix a potential oil leak.
The truck recall includes 490,200 2014 Chevrolet Silverado 1500 and GMC Sierra 1500 pickups, and 2015 Chevrolet Suburban and Tahoe and GMC Yukon and Yukon XL SUVs equipped with a 6-speed automatic transmission.
And the automaker also said it will resume selling certain Chevrolet Cruze sedans it had pulled from the market last week after inspecting a potentially defective axle part.
