We got theC Max as a motability car in October 2013 and almost from day one it's had this issue saying Child Lock Malfunction Service Required.

Ford and the Ford garage the car came from have been trying from almost day one to fix this problem and to day it's still coming up, they have changed so many modules, ripped out and replaced wiring in the door, said it's caused by water getting in the door and wing mirror and still no final solution.

I've been on the Ford C-Max owners forum and lots of people have had this issue and it was supposedly fixed by a software update mid 2011 yet my car was built in September 2013 and yet it still has this issue.

Are there any other C-Max owners who have this issue and if so have they got it fixed?
