Ford F-150 Powerboost whistle? 667B0467-7D45-46EB-B0CB-FF4AA53E3642

About 850 miles on my new PB. So far loving it. Pic from the owners manual. I noticed the whistle today. To me seemed to align with transmission shifts through the gears and not so much with hybrid and or turbos spooling.

A slight whine is one thing but what some are reporting is actually quite loud.

Exactly. I've also been in many EV's and Hybrids. NONE make this noise.
Agreed. My father's 22 Highlander hybrid is virtually silent when in EV mode. At best it puts out 1/4 the noise that my PB does and mine's fairly quiet by comparison to many of the ones in this thread.

Same. Sounds on the outside - I get it. Sounds on the inside - doesn't line up. In-Law's have a hybrid Volvo which is dead quiet. I'm sure plenty of people on here have been in a Prius, Tesla or other EV/Hybrid via Uber or Taxi - you hear them roll up like Tron, but when you get in there's no dog whistle to be heard!

My 21 PB also has the same issue. Has anyone tried changing out the diverter valve to a GFB one? I know some say the noise happens in electric mode as well. But maybe this will help a lot. I may just try it. Can someone help with the correct part number for the PB?

@Bigpb21 tried. I think the outcome (you can guess) is on pg. 5 or 6 in this thread.

@jmh686 From what I read there, @Bigpb21 had it replaced with another OEM one. Not specifically replacing it with the GFB valve that @Porpoise Hork mentioned. Maybe there is something inherently wrong with the OEM one and the GFB one handles it better and doesn't create the whistle.

Fair point. I wouldn’t have a guess on part number, but if you figure it out I hope it works!!!

If ford is blaming it on the electric motor, it seems like you would have the same issue or worse on the Lightning. Let us know if your lightning whines too. Thanks.

Lighting is quiet as could be. Someone from corporate did reach out yesterday but I informed them I no longer own it after months of dealer visits.

Anyone figure this out yet? Just checking. I also purchased a Lightning like @amatofilms. But am keeping both trucks. Would like to get this figured out and have the dealer take care of it. I am waiting to take mine in until next summer when it's hot and they can fix my air conditioner freezing up as well.
