2012 Focus Alarm keeps going off
I have the same issue and I have taken it into the dealership 3 times for it, the third time being today. I also have the issue with the hood alarm going off randomly as well.
What I was told today that since they cannot duplicate the problem (I asked them if they knew the definition of random) that they have to talk to the Ford Engineers to see if anyone else has had this problem and, if so, what would be the resolution. I can now assume that Ford mechanics possess no problem solving skills unless the Ford Engineers tell them what their skills are. I am very disappointed in the answer I got today.
Hopefully your issue was fixed and if so, do you know what they did to fix it?
