Little late for an answer to this post but hopefully someone else will use this info. This is something you can do yourself safely and save a lot of money. You can remove the module causing the problem and have it rebuilt for about $150. Then re-install it and problem solved. modulemaster.com will answer all your questions and provide instructions. Of course the dealer says only they can provide the part and replace it....they want your money to the tune of a couple thousand dollars! I'm so glad I researched it on the internet and found this low cost do it yourself solution. good luck.
