Any idea what this could be? Should I wait till my next maintenance in 4 months, or just bring it in now?
I have what is probably the same the squeak/chirp noise that is very dependent on temperature. I hear it at idle on a cold morning, temp about 20-40F, and when accelerating away from a stop or letting off the throttle in 1st gear. Typically it goes away for me as the powertrain warms up.
The dealer hasn't been able to duplicate it yet, but it's quite obvious. Please update if you have it resolved or determine the source.
My cold start idle is also slightly rougher as the idle drops down below 1000 rpm than when up to temp, but every 2012+ Focus I've driven has been similar. It always smooths out as the engine temp comes up for me.
