No, I've read the TSB's on them.

Corners? We don't make our cars to go around corners. Why would we do that?

Ouch. Like the Ford Exploder of yore.

Actually, it's more like the early versions of the Mercedes M-Class, which exhibited severe suspension jacking in a similar maneuver. The narrator cites the ESC system as not performing. This does seem like a severe problem, and I haven't heard of it before. Also can't imagine that many blown tires. It's not clear either whether this car has different specs than the U.S. version. (Might mention I ran similar tests on SUVs for about 20 years or so.)

I've owned/leased three Grand Cherokees. Never had a problem with stability. The chances of having to swerve like that are very, very remote. Also, it appears that the driver never hit the brakes. Who wouldn't brake or at least take their foot of the gas in that situation? Could the car be better? Sure, but that video wouldn't keep me from buying another. Of course, right now we own a Volvo XC60, which will last forever.

Of course, right now we own a Volvo XC60, which will last forever. The odds of needing to swerve rapidly to avoid something in front of you are not all that great, but the maneuver (dubbed a double-lane change) is a standard test of stability and handling predictability. It tests whether it is easy to set up an oscillation in the suspension that could cause a loss of control or a rollover. The car should wash out, probably slide, but should not begin that kind of bounding or lifting wheels. As for braking, that would likely initiate a quick spin in that maneuver.

Turns out the car was re-tested and passed the double-lane change fine. Dunno what caused the episode shown, however.

It was re-tested after a software upgrade, then it passed. It still looks a lot less stable in the test than its opposition.

Looks perfectly stable to me in the re-test: http://www.autoblog.com/2014/01/02/updated-2014-jeep-grand-cherokee-passed-controversial-moose-test-video/

Always change all 4 tyres at the same time?

All service done at the Volvo dealer at their specified interval.

On all wheel drive they are, that's something I have to keep my eye on , ( thanks for the reminder, I have to swap em front to back on the subie)

I even had trouble changing the OEM tyres to better ones, they had to be within 2 ( or was it 3 ) % of the OEM diameters to keep my mechanical warranty.

Mine is at 165,000 and doing fine.

The manual is my old 325i had 260,000 when I sold it, and it was turbo'd with 350hp.

Its a pretty common service and warranty package over here. We have it on the new Explorer as well until 100,000 miles all service is free.

Hmm... burnout time at 99,000 miles eh? I suppose they monitor engine revs, etc?

This one makes me crazy. Most OEM tires are absolute crap unless you are buying the top-of-the line trim package of a particular model, and AWD is useless with crap tires.

Honeybunny doesn't let me do burnouts in her car. Besides how does one do a proper burnout in a modern SUV equipped with full time and and traction control?

Yeah, tell me about it. My hire car (an American-made Honda Civic) was nanny-state material. Made it difficult to get through sand dunes (there was a button... but I managed without figuring it out). Did manage to get it airborne numerous times though.

My hire BMW F800 wasn't much fun offroad. Brakes didn't work. Yeah... once again, there was a button... but no destruction manual on how to go about disengaging / re-engaging, so I didn't bother. Who needs brakes, eh?

Oy! I just watched the video. Blowing tires on a simple avoidance maneuver is pathetic. Well, at least it didn't turn over. http://www.reduser.net/forum/images/smilies/rolleyes.gif
