I have an issue with my 2011 Edge (have the MyTouch system). I hear a very high pitched tone emitted from underhood (almost like an alarm) that can been heard ~20 ft away from the vehicle. This noise is generated with key in the off position after driving (key can be in the ignitiion or removed); it stops after a short period of time ~20s (I need to actually record the time) when you hear a relay click underhood. The dealer reviewed the issue, talked with Engineering, and assessed several other Edges - they came to the conclusion that it is normal; however, I cannot believe that this is true. My question - is anyone else out there experiencing the same issue and have you addressed it? It is rather annoying and I would like it resolved - thank you for your input.
P.S. I have also had multiple MyTouch system issues: loss of clock, multiple reboots, and poor transition from SD music to phone (music volume is increased just prior to switching). I also had a wind noise issue that the dealer was able to fix with some work to the driver side mirror (TSB was issued for this).
