The 2012 Lexus GX 460 hasn't been crash-tested by either of the two major U.S. safety agencies. But the GX 460 is quite closely related to the Toyota 4Runner, which has earned a mostly impressive set of scores from the IIHS. Plus, safety equipment—both passive and active—is extensive, including some more sophisticated accident-avoidance features.
In addition to the usual stability control and anti-lock brakes, Lexus claims that the GX 460 has a best-in-class ten airbags, including front side, rear seat side, and three-row side-curtain bags, plus knee bags for both front occupants. Active front head restraints also enhance rear impact safety.
Unfortunately, with the beltline brought even higher than before and a thicker back pillar, the blind spots have grown, leaving you to double- and triple-check when changing lanes. A back-up camera is now standard, but a wide-view front and side monitor system that helps a lot more is optional and requires the navigation system.
Safety Connect—a GPS-based roadside assistance system—is included with all GX models. And the GX 460 has a few features that might actually help avoid an accident. The Pre-Collision System primes the braking system for emergency braking and employs a driver monitor system; it's packaged together with Dynamic Radar Cruise Control and Lane Departure Alert, sounds a buzzer to warn the driver if the vehicle strays out of lane markings.
