I've been driving my 2012 ford focus SEL with MFT for over a month now. Most of my MFT problems have been resolved. However, I have begun to really notice that the a/c system makes a low level hum when on, and that the screen has a constant buzz. Took a while to discover what was bothering me while driving, but I can isolate it when I turn the system off/on with the engine off. I notice it while driving (it is not masked) and it is really draining my enjoyment of the car. Has anyone else noticed this and has anyone dealt with a dealer about this problem?
