No, thats not it. As I said before, one of my previaous vehicals was a 2006 Grand. It's when driving as you say above that the rear end is kicking out and I don't believe it should.

I've been driving Chicago winters for 20+ years in every conceivable type of vehical so it's not that I'm green. Drawing on all the experience I've had I believe this Jeep should handle much beter than it does. I'm just not sure if it's a issue with the design or something not functioning properly with my truck.

<edit> I think Foggy may be on the right track with a poor choice of stock tires by Jeep.

I agree with you. It sounds like your vehicle is exhibiting typical RWD behavior in low-traction scenarios. There's really no way the tail should kick out like in 4wd. If anything, you'd probably do more of a "4 wheel drift" if you were screwing around in snow while in 4wd. I've done it a ton of times myself in an empty parking lot on various 4wd vehicles.

Re: Unsure about snow performance

when I had my 99 GC with QD I could do what ever I wanted in snow and never got sideways. This was before traction control or any other computer assistance. Once I switched to my 02, 07 and now 2011 GC with QTII I have to be more careful in the snow. Driving threw my subdivision in the snow with multiple turns I have to be careful not to slide threw the turn or have the rear kick out. I have learned to adapt to driving this way, but it was nice having the feeling of a more stable Jeep back in the day.

Re: Unsure about snow performance

The rear end of my vehicle will come all the way around very easily if I gun it just a bit. I did not expect that from a vehicle these days with all the traction control etc. Very surprising from this new Jeep.....although our roads are bad....and I see others sliding too. Maybe its the relatively short wheelbase?

I may go take a ride in my old Acadia to compare.....cause this does NOT meet my expectations.

Re: Unsure about snow performance

We had good snow last week and starting traction was good with Std Goodyear Fortera HL. But cornering was suspect. So opted to Change 20" std wheels and tires for 18" Rims and Bridgestone Blizzaks DMV1 winter treads. Change was noticeable! Much better. So added nice Tire rack for Garage to store std one and use winter one's for 3-4 months and put 20's back on in the Spring!

All is good

Re: Unsure about snow performance

I imagine I'll run a set of winter rubber too, maybe even studs since we get a lot of ice.

At least I'd rather have it handle like a RWD than front. Despite what everyone might think front wheel drive is the worst in slick conditions. You might be a little better off until you plow the front end and drive right off the road. At least with RWD you can carefully modulate the throttle and its easier to correct to keep the rear from snapping around.

Anyway considering all the advanced traction systems in the jeep the tires are clearly the weakest link.

Re: Unsure about snow performance

I found my '06 RWD Charger with snow tires was better on ice and in snow than my '04 GC with all seasons. It made me a believer in having snow tires for winter driving. We haven't had much snow yet to test out my '11 GC with snow tires, but so far so good.

Michelin Latitudes that come on the 18" wheels are pathetic tires. I'm on the 20" wheels with stock Fortera HL rubber in Chicago and have been pleasantly surprised/impressed by the Fortera HL snow/ice performance on the street. If I had gotten 18" wheels, the Latitudes would have been removed and replaced with Firestone Destination ATs before I ever got home from the dealer after picking up the WK2. The best 4x4 system can be defeated by placing poor tires on the vehicle.

Re: 2nd Breakdown in just over 2 weeks!!!
Update:
The dealer test drove the Jeep in the desert and had the same problem again, but it resolved itself the moment they got it back on tarmac. So basically it does not have 4WD while off-roading.
They do not know what the problem is and therefore sent the fault codes to Chrysler US. They are expecting an answer on Monday 20 Dec.
Until then I will just drive it on-road and hope for the best.

Re: Unsure about snow performance

Had my first experience with our WK2 Overland, V6, Quadra-Trac II. Only an inch, but was enough to cover the roads and make a mess. This is our 6th Jeep Grand Cherokee, I had a 1997 with Quadra-Trac, 2000 with Selec-Trac, 2002 with Quadra-Drive and a 2006 with Quadra-Drive II. This jeep is by for the most sure-footed out of all of them. The traction control takes some getting use to because it does make clacking and groaning noises, however it is far quicker to get the power down then any of the previous systems. I'm very impressed. I drove up and down some steep hills and HDC is amazing!!

If this Jeep turns out to be reliable it will be the best GC yet!

Re: Unsure about snow performance

It seems like most people posting positively about their snow experiences have the 20's, I guess Jeep put some real snow-turds on the 18's.

Re: Unsure about snow performance

Since I live in Florida, I don't expect to drive in snow. Both of my vehicles(09 Ranger and 2011 Laredo X, Hemi) have Michelin Latitude Tours and my opinion is they're great tires for rain and dry roads. They will also last with proper rotation. Sounds like the folks in the snowy areas will have to strongly consider snow tires. I know I'm glad I didn't have to "settle" for Goodyears. Never had any decent Goodyear tires. Especially those Goodyear Wranglers!
