This isn’t supposed to be a problem anymore, but a Swedish publication found during its “moose test” that even at moderate speeds the Jeep Grand Cherokee is at serious risk for a potentially fatal rollover.
Vehicles are set to a certain speed during the test, in the Jeep’s case 39.5 mph, before the driver swerves through some cones in a simulation meant to mimic a panic situation. The previous generation Grand Cherokee passed the same test in 2005 without any problems, but as you can see in the image above, the truck rises quickly onto two wheels.
It’s a situation that would likely prove fatal for an unprepared driver, and one that other vehicles proved competent in avoiding — even at higher speeds. Those cars included a BMW X5, Volkswagen Toureg and Volvo XC90, all of which passed the test at 43.5 mph.
It’s not clear why the SUV performed so poorly, especially as, like most modern SUVs, it uses a sophisticated stability control system mean to intervene and prevent such dangerous situations.
In April of 2010, Consumer Reports gave the Lexus GX460 a Do Not Buy rating after it showed a similar reaction in that publication’s tests.
