Two days ago, news broke that Consumer Reports was taking an unusual step by putting its "don't buy" label on the 2010 Lexus GX 460 because of possible rollover concerns. Those concerns were caused by a stability-control system that CR said was too slow to intervene in cornering tests.
In response, Lexus stopped sales of the GX and offered loaner cars to customers who had already purchased a GX. Now, the company says it has a fix in the works for the issue.
The fix appears to involve adjustments to the stability-control system, although it's likely Toyota may make other changes, such as to the suspension components or tires and wheels.
Toyota is making the changes on its own accord, likely in a effort to get out in front of the story or to prevent further intervention from the government. Either way, it's an unusually fast response from an automaker, and it's probably not shocking given what's happened to the company over the past few months.
