Lexus announced the official recall for the 2010 GX 460 sport-utility program yesterday, but the Japanese luxury brand recently issued a video demonstrating its revised stability control system.
With the original stability control system, the GX exhibits the pronounced lift-throttle oversteer first publicized by Consumer Reports. When equipped with the revised stability control programming, the same GX corners without incident. You can watch the entire comparison video by clicking here.
According to Toyota, oversteer is a symptom only on its right-hand drive GX and Land Cruiser Prado models (which are only sold overseas). Both SUVs already have a number of hefty components (i.e. the gas tank) mounted on the left hand side of a vehicle. When the driver, steering column, and other components are placed on the same side, the weight distribution is unbalanced, and can provoke understeer in extreme right-hand corners.
As we reported yesterday, the automaker plans on recalling all afflicted models and upgrading them with the revised stability control. Nearly 13,000 Lexus GX 460s are affected, 9400 of them in North America alone. Another 21,000 Land Cruiser Prados — only those built in a left-hand-drive configuration with the kinetic dynamic suspension and stability control — will also be recalled.
Lexus dealers in North America will reportedly have the software update by the end of April. Owners will then be able to bring their GX 460 in at their earliest convenience, and the update should take roughly one hour to perform.
