2018 Expedition Max whining noise

2018 Ford Expedition Max 4x4 with Ecoboost makes a whining noise after outside air temps exceed about 60 degrees and after hitting about 25 miles per hour, a/c is off, trans in auto or Manual, My Ford Dealer in Las Vegas now says it's coming from the bell housing on the 10 speed transmission after they just replaced a rear wheel hub and bearing last week thinking that was the cause. They are saying this noise its not covered under warranty, they say its normal operating noise even though I've had it for a year and never heard this noise before, it just started a few weeks ago. I can't believe this noise is normal and I just have to deal with it. It sounds like a friction noise, and I know friction causes wear. My whole family has owned nothing but Fords for the last 20 Years, this will be my last one if they don't resolve this. I also just had a very disturbing timing chain noise repaired under warranty last week @ 24.000 miles no less, it may have been cam phasers or something similar. This will be the forth problem with our Max since buying it last year. They had to replace the dash a few weeks after we got then car because it lifted up in the center from our Vegas heat. We treat this car like a baby, it has not been abused, my wife primarily drives it and we only towed a 6000lbs trailer once for about 5 miles. Anyone else experience this whine problem?

Try another dealer

Yep! that may happen after talking to the service manager on Monday.

Does the sound change pitch with engine RPM or with driveline speed? Almost sounds like a bearing going bad.

Good question! The overall sound pitch gets higher at higher driveline/road speed speeds, over 50mph its pretty high and hard to hear. When I punch the throttle at 25mph to raise the engine rpm's for a second it doesn't seem to affect the pitch or speed of the whine. The weirdest part is the pitch of the whine (or) "rpm pitch of the whine for a better description" seems to change up and down while at a steady engine rpm and mph. You can hear this in the audio at 22 seconds and again 34 seconds, I was locked at a very steady speed around 8th gear and you can hear the whine change pitch. Im pretty sure its coming from the drive train and not the engine based on the above. If it does end up being the trans bell housing I'm not going to accept this is normal. Its too loud to ignore.

Yeah, time to try a different dealer if you're getting the run around at your dealer. This is not normal. Mine has never made this noise.

Im going to talk to the service manager tomorrow, then I'll decide what my next step will be.

The loudest whining noises I hear are usually from somewhere in the back after about 5 minutes of driving. The sound varies, but is usually kinda high pitched and long the lines of "I can't reach my water bottle" "why do grandma and grandad have to live so far way"... maybe I should bring it up with the dealer next time I take it in...

Lol, Sounds like the whining noise in your vehicle is serious. You better be careful that can cause an accident.

I’ve heard some sort of a whine out of mine if I’m at highway speeds with the 4x4 running but nothing like what’s on your video.
