I have a 2010 Focus approaching 90K miles.
I am noticing a "Buzzing / Vibration" noise when the vehicle is cold.
Sounds like is could be coming from the transmission when cold.
Happens only when cold and there is a load ( acceleration ) on the vehicle.
My initial thought when I first heard if was trans.
The noise almost sounds like an exhaust system pipe is all of a sudden against something...( That's the kind of Buzzing it makes ).

Once the engine is warmed up it goes away completely.

About 5K miles ago, I had the trans completely flushed and the filter replaced.
Also just replaced the passenger side engine mount (OEM)

Any ideas?

Any chance you could upload a video to YouTube of the sound and post a link here? It could be any number of things. If we can give it a listen it might help us narrow it down for you. []

I started up the vehicle this morning ( outside temp was 30 degrees ) and found no issue.

When I had the issue yesterday the outside temp was 10 degrees.

It is suppose to be near zero tonight. Will try to record in the morning.

It has been suggested to me that "Maybe" during the engine mount replacement that the raising of the engine might have shifted the mating sections of the exhaust system and now something is a bit too close to something else.

Who knows, will see if the symptom repeats in the cold tomorrow.

If the symptoms return, I recommend heading to your dealer to get it checked out. Please let me know if you do, and I'll check into any available options.
