Driveline Noises in 2020 Escape Hybrid

Driveline noises and vibration from front end of 2020 Titanium Escape Hybrid. A low pitched pulsating sound continues to come from the front end. Definitely rotational. Accompanied by detectable slight vibration in steering wheel. Left foot on floorboard can sometimes detect vibration with noise. History-when new, very quiet. At 500 miles, noise, with no detectable vibration noted. At 1200 miles taken to dealer for investigation. Was told this is normal for the hybrid. No work performed. This forum advised wait for the service procedure to reprogram the computer/transmission to address noises. Reprogram done in May, soon after announcement , at 1800 miles. Still no improvement. Now at 2500 miles, sounds and slight vibration more apparent. Tried to record sound with no success, to demonstrate to dealer. Called dealer to drive an identical 2020 Titanium Hybrid to hear if these noises are "normal". None available, including 2021 model. To elaborate, the noises are not tire or road noise, which can be discerned. Balanced, presssures ok .This is not engine exhaust noise, which can be discerned. The noise/sounds are usually apparent when cold, however become more apparent after driving for 5 minutes, cold or hot weather. Left hand turns intensify the sound, but you have to be listening. Rolling at constant speed sometimes produces the sound, with no acceleration or braking. Acceleration brings on the sound but it is not exhaust sound. I am thinking along the lines of driveshaft,cv joints, transfer case, electrical generator. Something rotating-speed doesn't change much with vehicle speed.
Other than driving me nuts for the past 10 months, the car is great. Occasionally get 63 mpg on 20 min trip, lots of battery use. Going back to the dealer again to try and get some answers. I just don't think this is "normal". Have had other brand hybrid, no noises. Comments from 2020 Escape Titanium Hybrid owners encouraged .
