  1. From the “All DTC’s” tab, select the “Clear Stored DTC’s” button.
  1. Select “OK” from the pop-up text box.

Owner Notification and Service Scheduling

All involved vehicle owners known to FCA are being notified of the service requirement by mail.  They are requested to schedule appointments for this service with their dealers.  A generic copy of the owner letter is attached.

Enclosed with each owner letter is an Owner Notification postcard to allow owners to update our records if applicable.

 

Vehicle Lists, Global Recall System, VIP and Dealer Follow Up

All involved vehicles have been entered into the DealerCONNECT Global Recall System (GRS) and Vehicle Information Plus (VIP) for dealer inquiry as needed.

GRS provides involved dealers with an updated VIN list of their incomplete vehicles.  The owner’s name, address and phone number are listed if known.  Completed vehicles are removed from GRS within several days of repair claim submission.

To use this system, click on the “Service” tab and then click on “Global Recall System.”  Your dealer’s VIN list for each recall displayed can be sorted by: those vehicles that were unsold at recall launch, those with a phone number, city, zip code, or VIN sequence.

Dealers should perform this repair on all unsold vehicles before retail delivery.  Dealers should also use the VIN list to follow up with all owners to schedule appointments for this repair.

VIN lists may contain confidential, restricted owner name and address information that was obtained from the Department of Motor Vehicles of various states.  Use of this information is permitted for this notification only and is strictly prohibited from all other use.

We are recommending the following improvements be performed on certain 2005 through 2010 model year Jeep® Grand Cherokee and 2006 through 2010 model year Jeep® Commander vehicles equipped with a Quadra-Trac II Full Time Active 4WD transfer case.

Recommended Service: The Final Drive Control Module (FDCM) software on your vehicle may cause the “Service 4WD” light to come on and an inability to switch 4WD mode when trying to shift out of the current selected mode.
What your dealer will do:   FCA will service your vehicle free of charge (parts and labor).  To do this, your dealer will reprogram the Final Drive Control Module (FDCM) with new software.  The work will take about ½ hour to complete. However, additional time may be necessary depending on service schedules. We recommend that you make an appointment with your dealer to minimize your inconvenience.
What you should do: Simply contact your Chrysler, Jeep, or Dodge dealer, at your convenience, to schedule a service appointment.  Your dealer will collect the necessary information to ensure that the appropriate parts are available so your service can be completed in a timely manner.  Although not required, we recommend bringing this letter with you to your dealer, when you bring your vehicle in for this service.
If you need help:

 

Please contact the FCA US Customer Assistance Center at 1-800-853-1403.

 

 

Please help us update our records by filling out the attached prepaid postcard, if any of the conditions listed on the card apply to your vehicle.  If you have further questions go to recalls.mopar.com.

Box 21-8004, Auburn Hills, MI 48321-8007, Attention: Recall Reimbursement.  Once we receive and verify the required documents, reimbursement will be sent to you within 60 days. If you’ve had previous repairs and/or reimbursement you may still need to have the recall repair performed on your vehicle.

 

We apologize for any inconvenience this service may cause to your schedule.
