I thought this was covered in JeepForum. I read that the computer is VERY picky about how it's flashed for this recall. There is something in the instructions about after flashing, the tech should clear codes 3 times. I read that most techs don't read the instructions, flash, and move on. Those who went back and had it reflashed had their problem solved.

I can't find it now, but there was also some funny post on FB about how someone solved their problem by driving a few feet, pulling a fuse, then driving back, replacing fuse, then engaging 4lo, or something like that. It figures I can't find it now. I would print out the N23 recall instructions and go back to the dealer.
