What I'm saying is, if the recall has been performed, and people are getting service 4wd messages, then they reprogram the transfer case control module (pretty much same this as the recall) and it is submitted as a regular transaction. So to say, they won't do it again because they won't get paid for it is false.
Edit to add: There is currently as Preliminary information bulletin describing multiple service 4WD messages, and engineering is currently looking for a solution. Until then, dealers are to perform the TCCM reprogram.
