Apparently the error can still occur in 4Lo (that is, the serv 4wd error can still appear), but because the centre diff is locked you aren't forced into 2wd.

This is, from my understanding, correct. At least there is one way around it

Re: SAND driving - Have you had a problem with your GC?

I couldn't resist having quick look at the data. There is nowhere near enough data to come up with anything definitive however there are a couple of stand outs. Overlands are overly represented with sand failures by 5:1. This may be nothing more than Overland owners having higher expectations. I say that because QL and QDII are not showing any pattern. All 6 vehicles manufactured in the latter half of 2011 had sand failures, of these only 3 were Overlands. I have to reiterate that with so little data one cannot say there is any significant trend.

Re: SAND driving - Have you had a problem with your GC?

I had this SERV 4WD message today (18/03/13) while driving along the beach near Dawesville Western Australia. Very scary and annoying loosing 4WD. I was fortunate to get off the beach in 2WD before driving straight to the service centre. They were embarrassed and stated that they were aware of the problem but were not clear as to what was required until they actually get my Jeep in there. It is booked in there Friday for a service and to hopefully rectify this very serious issue.

I took my 2011 JGC diesel for a service today in Bunbury. They advised that they had no definitive fix for the problem prior to the service. After the service they advised that there was an ABS lockup problem when I was on the beach, possibly due to the wheels spinning too much which caused the 4WD system to disable. Last I knew, wheels are going to spin off road with a 4WD! They said they found a stored error message on the computer which they cleared. I asked whether Chrysler will be notified and was told that if the error was active they would but because the error was stored they wouldn't unless it happens again (hopefully I'm not on a boggy beach with the tide coming in). I asked for a guarantee that the issue would not resurface but was told there was no guarantee and that I just had to monitor it. These issues are in my opinion very SERIOUS and need to be addressed by Chrysler as someone could be in serious danger if they get caught out in a remote area. I know all vehicles have mechanical/electrical issues but I haven't heard Landrover having issues with its extensively advanced electronic 4WD system on its late model D3/D4's. When the 4WD is active the JGC is more than capable but it needs both diffs to work for that to be the case.
My Jeep in a late 2011 CRD with Quadra Trac 2, coil sprung suspension. I have done a bit of beach work prior to this with no issues but did fit new larger tyres prior to this problem surfacing.

Re: SAND driving - Have you had a problem with your GC?

You should read this thread if you haven't already:
Grand Cherokee + sand = FAIL

The only way to get this issue fixed is to contact Chrysler customer support in Melbourne (contact details in thread above).

Made it to Straddie in the sand yesterday in my MY14 (April 13 Build Australian Delivered) Laredo CRD. Very soft sand and the car went fine. Only spent about 15 mins in the heavy stuff.
Sand mode selected and offroad 2 height on the QL. The car also has Quadra Drive.
Awesome!
Cheers.
