The moose test is a lighting-fast emergency lane change maneuver that takes place at a relatively staid 40 miles per hour. While most vehicles clear the obstacle with little fuss, the below video shows that a Grand Cherokee Overland got up on two wheels and very nearly rolled. Teknikens Värld tester Linus Pröjtz points out in the Overland model comes standard in Sweden with 20-inch wheels, rollover protection and electronic stability control.
The Swedish car magazine (translation: "World of Technology") goes on to call on Chrysler to put a stop sale on the Grand Cherokee in Sweden until this issue is addressed, and they claim Chrysler has yet to provide an explanation as to why the vehicle performed so poorly.
Here in the States, the National Highway Traffic Safety Administration awarded the Grand Cherokee four stars, including a five-star score for side impacts. However, in rating the SUV's rollover resistance, the GC only managed three stars in rear-wheel drive configuration, while four-wheel drive models netted four stars.

*UPDATE: Chrysler brand fan site Allpar has published an article that alleges that the rollover test was rigged, arguing the test was conducted in an intentionally overloaded vehicle. Further, it reports that the magazine conducted the test again – with Chrysler engineers standing by – in three different correctly loaded Grand Cherokees over eleven separate runs, but they were "unable to reproduce" the wheel lift condition.
**UPDATE: Chrysler confirms it is actively investigating the test and has just furnished Autoblog with an official response which you can read by scrolling down.
Grand Cherokee Statement for Teknikens Varld Test
Chrysler Group engineers are investigating a Swedish magazine's evaluation of the 2012 Grand
Cherokee. During the evaluation, the publication was able to capture images of a Grand Cherokee on two wheels as it performed an extreme maneuver in an overloaded condition.
Advised of this event by the magazine, Chrysler Group engineers made numerous attempts to
reproduce the wheel-lift in a properly loaded vehicle. Extensive testing produced no such result.
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.
The uncharacteristic result was obtained using a vehicle loaded beyond its weight specifications. The Grand Cherokee's weight limitations are clearly stated on the vehicle and in the owner's manual. Also, the extreme maneuver performed by the magazine is not certified by any regulatory agency, nor is it used to establish any sanctioned safety ratings.
Chrysler Group takes seriously any safety concerns and engineers are examining the event to better understand the magazine's claims.
A "Top Safety Pick" of the U.S. Insurance Institute for Highway Safety, the 2012 Grand Cherokee is an award-winning SUV that features Electronic Stability Control and Electronic Roll Mitigation as
standard equipment. It meets or exceeds all government safety mandates and its outstanding
performance has made it the most awarded SUV in history.
