The recall affects about 9,400 vehicles that have been sold since the SUV went on sale in late December. Consumer Reports issued a "Don't Buy" warning last week on the 2010 GX 460, saying it was susceptible to rolling over.
Toyota says dealers will update software in the vehicle stability control system. Toyota already had halted sales of new GX 460s and begun tests on all of its SUVs.
The automaker also agreed to pay a record $16.4 million fine on Monday for failing to properly report a safety problem with defective gas pedals.
