Re: STUCK IN SAND with 4WD malfunction

That's an interesting point then. Does everyone that get's this SERV 4WD message, also have quadralift on their GC's?

It might explain why some get the error and others dont.

I don't think that having quadralift is specific to the error appearing when driving on sand.

I have a 2011 Grand Cherokee Limited without Quadralift and this is my experience.

2nd day of ownership and I thought it would be a good idea to take a little drive on 7 mile beach Lennox Head (AUS) to test her out. Having watched a for Jeep middle east I thought it would be a piece of cake.

So I got it onto the beach through the soft stuff easy, I thought this is nice, cruised for 5 minutes on the hard wet sand before turning around to head back off the beach as it was getting late.

I got near the exit run up about 100 mtrs of soft dry sand checked no vehicles were coming in then proceeded to pick my line and hit the gas, to my dismay I got half way and lost front wheels and sunk to rear axle Serv 4WD light on the display.

Bugger, I rang Jeep Service center in Brighton VIC where i bought the jeep, never heard of the error was told to disconnect battery to see if that would help, no dice error persists. Rang Jeep assist, no help because I'm off road. Rang independent towing companies, no one can tow me off the beach, I thought well I'm screwed, two other 4wd's on the beach stopped to see if they could give me a hand but no one had and sufficient slings or gear and thats when I found out my 2011 is actually a 2012 spec with the pissy little eye bolt.

I borrow a shovel and start digging, after clearing around the axle and rear wheels I jump in turn on ignition, the error is gone but seconds later is back after doing nothing no IE no gear change or acceleration.

So i turn off and on and as quick as i can put it in reverse a hit the gas, presto I'm out of my hole but stuck again 3 meters back when the error returns and front wheel drive fails. I repeat the steps and manage to get back on the hard sand and after 10 attempts back and forward cutting a track with my 4 seconds of 4wd I manage to make it through the soft sand and onto the access track, as soon as I'm on the road the error disappears, i head to the closest servo and inflate my tyres then get home and goggle the Serv 4WD error which leads me to this and other threads.

Later I ring Jeep Lismore and tell them about the ordeal, they said they have never heard of the issue, I bring the Jeep in but they find no fault codes and say there is nothing wrong. Thats Bull I didn't imagine that I nearly lost my 60K Jeep over a Serv 4WD error.

Unsatisfied I call Jeep Newcastle NSW as its apparent people have had similar issues with their WK2's in the Newcastle area.

The service manager there was great, he stated that he was aware of the issue and that Melbourne Head office and Chrysler USA are aware of the issue and that they are currently testing a fix that is soon to be released.

I might call Newcastle Jeep again and see if there is any progress on the fix.

When did you contact the service center at Gateshead. I was about to call them as a few victims, who apparently had the same problem, have got it fixed with the new TSB (http://www.wk2jeeps.com/tsb/tsb_wk2_0803412.pdf). I am really disappointed at Chrysler for not informing us about this issue before or after buying the car. Secondly the recovery points in front not really capable for snatching the vehicle out of situations like these.

Re: STUCK IN SAND with 4WD malfunction

I spoke to them about 2 weeks ago, I'm a little skeptical about that TSB being applied to my vehicle as I don't have quadralift.

I have also heard that Jeep is working on a recovery fix which should be installed free of charge, in the mean time I have bought another eye bolt and a sling to spread the force across the 2 front points just in case I need to be pulled out.

I'm just really peeved that I cant goto Lismore Jeep for support as they don't have a clue about anything and I have to call Gateshead for any solid information.

If you find out any more info let me know.

Re: STUCK IN SAND with 4WD malfunction

I spoke to the mob at Gateshead and apparently Jeep is still working on the fix and the latest TSB wouldn't solve this issue. Apparently it has been 4-5 months since Jeep has been working on this issue !
The new recovery hook is in the market and costs about A$370. Have to contact the dealer from whom I purchased the car, if they are giving it for free for customers who placed the order without being informed that the front recovery hooks have been omitted in the 2012 model.

Re: STUCK IN SAND with 4WD malfunction

Interesting that all of these Service 4WD issues have occurred in sand using the mud/sand setting and I am assuming that no one has reported the warning light when running strictly in 4LO.

I just had this warning light come on while running in Rock mode, 4LO, but don't think I lost power to the front wheels. Not sure on that, see my post here about a trip through the San Juan mountains.

WK2 Trip - San Juan Mountains

I have run the Medano Pass road (Great Sand Dunes National Park) three times and didn't have this issue. Twice I ran all the way through the sandy parts in 4HI, using strictly the Sand/Mud option on the Select Trac and once I was in 4LO after watching a Rubicon struggle to free itself from the sand right after entering the sandy section coming down from Medano Pass. System worked fine.

This past week I got the warning light right after ascending Ophir Pass and was descending the other side when I noticed the light. I had been in 4LO Rock Mode, overrode the OR setting from OR2 to OR1 and had been making use of the Hill Descent Control. The previous days I had been on much more challenging trails, Mineral Creek and Imogene and never had an issue.

I did not receive a QL warning as others have with this issue.

I have a 2011 WK2, 5.7L, Overland with the QL. I believe the build on my Jeep is 11/2010.

It be interesting to hear from others who received this warning who were not in sand as well. The closest TSB match I have read that might reflect my problem is TSB 21-008-11, but have not had a chance to get to the dealer to check.

I've been on the beach twice since having the latest TSB's updated in my GC, and I can happily say I didn't experience any horror with error messages! So I assume the fix in relation to the problem I had was TSB 08-034-12. I really hope everyone else has their problem fixed soon, cause I know how disappointing and embarrassing it is.

Re: STUCK IN SAND with 4WD malfunction

I just suffered the service 4wd/quadralift issue in sand along with another GC. It's one of many issues with this car. If so many people are having this issue why didn't jeep notice this prior to going to market with this car? Surely the engineers would have driven it in sand to test it??

This is exactly the point that is indefensible. As per the service centre guys, this is a known issue since Feb/Mar 2012. I had written a formal complaint to Jeep requesting an explanation and the verbal response was that a fix is being worked upon and since it involves multiple other software functions of the vehicle, it has to be throughly tested before release. I heard another explanation that this problem is unique to Aussieland because of the difference in the texture of the sand. Whatever be the issue I feel it is Jeep's responsibility to inform this issue to customers so that they can take an informed decision. At least they should inform customers that driving in sand should be avoided but of course that will impact on sales !

I wouldn't say six months is a reasonable time frame to fix a fault....australian consumer law says it must be fixed in a reasonable time

That is a lie. Plenty of us Yanks have had the same issue, including me. I am still waiting for the "fix" also. Dealer won't do anything for me other than tell me "they're working on it".
