We have a 2010 Jeep Grand Cherokee Limited 4X4 with the 5.7 liter V8 HEMI MDS VVT engine, and the Quadra-Trac II Active Full-Time 4WD transmission.
This automatic transmission vehicle was extremely easy to shift into neutral for flat towing behind our motorhome. Clear instructions in the owners manual made towing the vehicle a snap ... no limitations, no special aftermarket add-ons. Perfect, and easy!
I say WAS, because now there is a problem, and Chrysler appears to be slow in responding and developing a solution.
In November of 2013 we had a recall perfomed. Identified as Recall # N23, it included a software update for the Final Drive Control Module - the computer that talks to the transfer case and allows us to shift it into, and out of neutral for flat towing. There is a flaw in this software update results in the EVIC (Electronic Vehicle Information Center) display to show that the 4WD system needs service, and the user is unable to put the 4WD system in neutral for flat towing.
When this happened to me on 4/25/14, we were packed up and ready to leave South Texas for the summer months. I took it to the Jeep dealer, where a Service Advisor told me that he had seen a number of "Winter Texans" in with this problem in the preceeding 90 days, and that the only solution he could offer was to "re-flash" the Final Drive Control Module. That worked,but it is a temporary fix that is only good for 5-7 days, and then it needs to be "re-flashed" again.
I am now 2000 miles from South Texas, and 7 days have passed. The car towed fine for the trip, and shifted back into normal mode for driving at our current destination. but I tested it today, and sure enough! the EVIC display reads that the 4WD system needs service again! So I am communicating with Chrysler Customer Care and a local Jeep dealer.
As it stands now, there is no solution in the pipeline for this problem, and it appears that Chrysler has not acknowledged that this is a problem or offered a solution. I truly cannot imagine having to find a Jeep Dealer and paying to have the Final Drive Control Module "re-flashed" every 5 to 7 days! I am posting this because I want to make sure that other Jeep owners are aware of this problem and to ensure that they help to communicate the need for a solution - URGENTLY - to Chrysler!
