Hi Guys,

Greetings from Vienna.
I love my 2015 V6 (exactly @ 20k miles), but recently I´ve noticed that when the engine is still relatively cold and eg. when slowing down and stopping at a red light the rpm returns to idle I hear a quiet squeaky noise between 1000rpm and idle, until the moment it settles at idle. When everything warms up, this is gone.

Have any of you ever experience this? Can you help what might cause this, what should be fixed? (belt/tensioner, IAC, throttle body issue?)

Thanks in advance, have a nice day!

I would still definitely get it checked out but if it makes you feel any better my belt is extremely squeaky when idleing cold, always has been. I know it has been noted on the 11-14 mustang V6 as well.
