As you can see from my post in May here I have had this issue for months.
Took it to the dealer their tech experienced the issue. They have no ideas and told me Fords service/tech line gave them no ideas so they reflashed the ECU. My dealer then told me it was working. I was doubtful.
Picked up the car last Thursday night, cruise control has failed to activate all but once. I drive the car a ton for work and try to engage CC 3-5x daily. No dice.
I call the service writer Friday and he tells me he has to call Fords tech dep't again that he would call me Monday.
I just got off the phone with him, I had to call him its now Wednesday and I heard nothing. He tells me the technician will need the car for an extended period of time. They need to "look at certain parameters while its not working". I told him he already had the chance to do so.
This is the stuff that infuriates me. He even wanted me to leave my car up to 1 week. Makes me want to call and cancel the extended warranty If this is the $hit I have to deal with on any issues. I even told him about the clock spring but of course we are the idiots.
