Following its testing of the 2010 Lexus GX 460's revised stability control programming, Consumer Reports revoked its unfavorable "don't buy" rating. According to the buyers guide, Lexus' full-size SUV is now considered OK to purchase.
Consumer Reports first discovered the Lexus SUV had a traction issue when performing standard handling tests. While executing a high speed turn, test engineers quickly lift off the gas pedal to check for lift-off oversteer. The GX 460 slid completely sideways before stability control kicked in, thus failing the test. The results forced Consumer Reports to place the GX 460 on its "safety risk" list.
Lexus quickly sprung into action, stopping sales of its SUV. Some 9400 vehicles were affected by the recall. Once they replicated the issue, Lexus engineers worked around the clock to rectify the problem. Customers were also offered a free loaner if they felt unsafe driving their GX 460. Just one week later, Lexus reworked its stability control system and began performing updates on customer vehicles.
Consumer Reports has since retested the GX 460 with its updated software. Upon finalizing its examination of the revised stability programming, Consumer Reports removed the Lexus SUV from its "Don't Buy" list. The GX 460 was the first vehicle to be deemed a "safety risk" by the magazine in nine years. The last vehicle to make the dreaded list was the 2001 Mitsubishi Montero.
