I think part of the reason you see these videos and nasty posts about Jeep is because the car is positioned as an off-road and/or snow vehicle to separate it from the competition. Many buyers aren't thinking the stock tires are going to hold them back. I don't believe the commercials have any kinda warning like "Requires AT and/or Snow tire" when they show the Jeep making mush of the snow or trail.

BTW. I have a set of cheapo floor mats in my GC just in case, since I'm riding on stock Forteras.

Re: "I don't know how to drive in snow/ice, so I blame my GC" Part Deux

The Jeep's computer can only account for so much incompetence, but this is beyond it's control.

All that was left to do was display on his screens, "STOP. NOW. YOU AREN'T DOING ANYTHING BENEFICIAL TO HELP MOVE ME!." and then it goes into a Daisy song sequence and self destructs to put everyone out of their misery.






Well, at least that's how I imagined it.

Does anyone think deflating the tires would help? I am not a pro in this but I understand one would get a better traction.

Re: "I don't know how to drive in snow/ice, so I blame my GC" Part Deux

Greetings,

Deflating the tires could work with the combination of moving the wheel. You increase your chances of getting a bite of traction. In addition, with the JGC, depending on your 4x4 plays a factor in this scenario. For example, if you have the Quadra Drive, one tire catches, it might be enough to pull or push the JGC out and the other tires start catching.

The interesting question here is, how much air should one let out?

In the video, I did not see or I missed something in the YouTube comments on which for 4x4 he had. QT 1, QT ii or Quadra Drive?

Best for now.

Re: "I don't know how to drive in snow/ice, so I blame my GC" Part Deux

Every attempt shown is in reverse. He never tries forward; and he never tries giving much less gas so as to not spin the tires. It also looks like he's up against a slight lip and with no traction and no momentum, he won't ever get up and over the lip that way. The lip could be the driveway surface, or could be packed snow/ice from all the tire spinning he's done.

Yes while better tires or studded tires or airing down would help, not changing anything except for technique he could get unstuck if he tried rocking back and forth (quickly - forward, reverse, forward, reverse, etc...), or going forward and getting a slight running start to get over that lip, or he can try putting something under the tires like a mat or kitty litter as others have already said. And also by not spinning the wheels so fast.

I don't care what you're driving, if you don't know how to drive you'll just get stuck if there's insufficient tire friction. Heck, a tank with treads, if on a surface where there's insufficient friction, will do the same thing.

From freshman physics, the coefficient of static friction is higher than the coefficient of kinetic friction, meaning, he has more grip by giving a lot less gas and not spinning his tires.

The guy's an idiot. He made himself look silly doing this.

He indirectly gives you that answer: Grand Cherokee Diesel: Quadra Drive. The rest of the visual clues (like the black edges to the wheel arches and the HID headlights) point out towards a Limited trim. That is a Limited with Luxury Pkg. and Diesel engine.

You all blame him for not putting branches, rubber mats under the tires, pissing on the ice to melt it, etc. Maybe he is exaggerating a bit by driving in reverse only. But none of you apparently have seen a normally functioning system QT-2 / QD-2 from the outside of your Jeeps when stuck. So if you haven't, mainly because you have not gotten stuck, you automatically assume the guy is a dweeb giving Jeep a bad name.

I've posted my own video, getting stuck in snow, nobody cared to compare what the wheels did in my case vs. his. What about this video (see min 0:50) which shows the same correct behavior of selectively slowing down spinning wheels (those with lessor no traction) ? Where do you see that in his video?



His car is to blame. And perhaps he is dramatizing it, after he found out the QD-2 (in his case) certainly doesn't work as it should in reverse, and that is why he only tries in reverse.

1.5 years ago, when describing my off-road experience, I stated:
The 2014 Grand Cherokee is quite capable off-road

Quote:
The car really jumps, when crawling up rocks, you can feel the system working. And yes, I would hear the wheels spinning at time, just briefly. Whatever algorithm it's using, it is pretty good. There is a video online of a 2011-2013 Grand Cherokee with QT-2 crawling up some slope and it is presented in comparison with Quadra Drive from a WK. I would like to say that my Jeep (I was the driver not an outside observer) was smother than that. Probably the enhanced computer power and the new transmission helped.
Having seen it working from the outside (in videos of my car or others) and having felt the transmission working, I am very comfortable saying that the Jeep had a problem. Here's another one - pay attention to what the tires do: they don't just keep spinning.

Greetings,

Thanx for the clarification on which transfer case he had. Knowing the capabilities of your vehicle is very important. I ask a longtime Wrangler and other Jeep owner at the time of my purchase to give me the pro and cons on Jeep's 4x4 transfer case. I also try to my homework. Great videos to watch.

The other thing that completely missed was the entire time he was in reverse as others and yourself also pointed out. As I watched the video again, I also seen the snow exiting from the front of the tires. Thus he put himself in a bind, the loss of any frication. Be that is it may, not once did he try any other standard type of technique to free he himself. Just the snow mode and 4Lo from JGC.

I also reread your earlier post # 14 and the link you provided to the thread Driveway Rated?.

"I don't know how to drive in snow/ice, so I blame my GC" Part Deux

Your thinking about the ABS is entirely possible. The JGC has made numerous trips for service as clearly stated in the YouTube post. The owner is clearly upset about this as any other owner would be. When I get a chance later, I have to catch up more on that thread.

The troubling part for myself and others who have posted here, a first-time buyer in the Jeep family or a potential buyer can get discouraged when viewing the video. The simple fact that is known and well pointed out in Driveway - Rated?, there is a big difference between parked in a driveway or in the street with snow/ice than off-roading in the snow/ice.

Best for now.

As one that got stuck on my driveway as well I would totally agree. I left my car on the snow-covered part of my driveway and overnite it turned to ice. So I couldn't move the car the following morning. No traction all spinning. So I took my little recovery shovel and took some ice out behind each wheel and it came right out.

I don't disagree with many of the comments, but to me, if the GC came with a more capable tire to match it's other capabilities I don't think many of these issues happen. I noticed in the dealer lot last week, the new Cherokees have a Firestone Destination AT option. Hopefully this or another AT is something that will be offered in the GC soon.

Greetings,

As I said prior, when I just had a regular car, technique is a big thing. As we move on, we learn new tricks to get us out of trouble. I always have a recovery shovel with a pick in the cargo bay for those just in case situations.

As for me with tires, since I got this beast with the Lat's, I was not happy camper. After trying the BFG Rugged Terrain, still not a happy camper. Finally, I got the Nokian and now I am happy. Long story short, with all my complaining with Jeep, I got free oil changes for my inconvenience for the LAT's.

You are 100%+ that better tires should come with GC especially for the advance packages or the region you come from. Something to that degree for the flagship vehicle from Jeep. Even Dest AT's does a decent job with ice, and does a very good job with snow. I had them on my old Xterra.

Best for now.

If he were to have Quadra Drive....he would be Trail Rated...as he claims in the video. But there is no Trail Rated badge. So....I don't think this is QD2.

I also think that he is backed up against something on the rear passenger's side that is keeping it from moving.

Actually I don't think that's true. Off-Road Adventure 1 is QT2 and you get the badge.

Don't all Diesel's come with QD? I know that here they do.
