Hi Ikatze2, I know this is an old post! but I purchased a 2013 Hybrid and have identical symptoms to what your post says. My model year is before the bolt recall and it sure doesn't feel like a loose bolt. When you went to the dealer did they just do the recall or was there something they discovered loose in the clock spring area making that clicking pop noise. Appreciate any answer you can give!?

Thank you Jon for a very comprehensive answer to my question. The electric motor whine does seem like the probable cause for the noise. However, I may have mislead you with it just being an electric motor whine noise. I do actually here the wonderful electric motors and delight in the sound idiosynchrosis of a hybrid vehicle. This sound is more related to the ICE part of motivation. One example of the sound it makes could be confused as wind screen noise, or whistling thru a tube. And is directly related to ICE intervention. You could say, it is less of an EV whine and more of a whistle. Another example: Turn on your vacumm cleaner and slowly put your hand over the suction part of the tube. It will make a whistling noise, pitch rising as your hand gets closer to closing off the tube and then a faint pop and an abrupt silence as your hand gets suctioned on to the tube. This is the sound that is heard when the ICE shuts off. That is why I had mentioned maybe air intake noise of some kind. It could also be like you said, MG1 shutting down just as the ICE shuts down and I am confusing it for ICE. Maybe I will take an FFH for a test drive at the local ford dealer and see if I can replicate it. Or if anybody else has an example of this noise it would be much appreciated. Thanks again Jon for your response. Don

FFH owner here for the last two months and a glorious 4,000 miles so far! Huge car nut and enthusiast. I am loving this car, but I have one issue with it that I haven't found much about online or on forum posts. The following is one forum post I did find that describes the problem and my following comment: Posted by: Akeel Zaheer | Aug 3, 2009 2:41:09 PM Bought a Ford Fusion Hybrid about three weeks ago. Have about 600 miles on it. Love it so far. Getting great mileage - avg 40mpg. Some trips I get 46 mpg if it is highway and city blend. One issue that I want other owners to comment on is a faint but distinct hum/whine when accelerating through or holding steady at speeds between 40-45 mph, Anyone experience this? Any thoughts on why this could be happening. appreciate any thoughts/comments. Posted by: Don | Sep 25, 2009 4:59:57 PM Akeel, it is amazing you mention that about the slight whine. I have the very same noise. It is not loud and happens at same time you explained. I was seaching on the internet with keywords "whine and "Fusion hybrid" and came up with this forum post. I can't find anything else however. It is good that at least I know somebody else hears the whine because my wife thinks I am being anal. Other than that, my Fusion Hybrid is awesome. And that is coming from a car enthusiast that owns way to many cars! Let me elaborate a little more. Sound is prevalent at steady speed with ICE, and when you step off the throttle to go into EV the sound dissipates, almost sounds as if its getting choked off, like suction thru a tube slowly being closed off. wondering if it is air intake reverberation , and it also dissipates when you are in ICE and push more on the throttle. The sound to me seems to be getting louder as I put on the miles. Starting to here it at speed around 60 with slight throttle application. Usually the stereo is fairly low or off in the car. Any comments would be much appreciated! Don

What works well for me in regards to keeping it in EV mode at low speeds and accelerating acceptably is to use what I call the " push and float method". I accelerate normally with assistance from the engine and then let off the gas all the way to let it get into EV mode and modulate the "gas" pedal to maintain speed while staying in EV mode.
