Minutes after we had a report about the Jeep Grand Cherokee failing a Moose Test in the hands of a Swedish publication, we heard from Chrysler saying the test was invalid and the vehicle was overloaded, and that the extreme maneuver performed by the magazine is not certified by any regulatory agency, nor is it used to establish any sanctioned safety ratings.

Jeep says they investigated the report and tried to reproduce the situation in which the Cherokee went on two wheels in a properly loaded vehicle, but to no avail: “A subsequent evaluation was conducted by the magazine July 8 in Sweden and witnessed by Chrysler Group engineers. Three vehicles performed 11 runs on a course prepared by the magazine. None reproduced the original event.”

There could have been a mix-up here. After all, the Cherokee is a Top Safety Pick from IIHS, and features standard Stability Control and Electronic Roll Mitigation. So either the U.S. Insurance Institute for Highway Safety knows nothing, or the Swedish team didn’t conduct the test properly.

In short, Jeep’s answer is: “The uncharacteristic result was obtained using a vehicle loaded beyond its weight specifications.”
