They admitted it’s not normal, but did no further digging than checking the hybrid module and removing and reinstalling the glove box. They returned the truck to me after that with the noise still occurring.
I took delivery of my '24 PowerBoost a few weeks ago. I have had a nasty vibration/grinding sound in what sounds like the engine bay from 800-1200RPM, on extremely light throttle application or higher idling. To me it sounds like some sort of heat shield flapping about.
It's been to the dealer...
