Update!
After reading
@Sinfiny info I went back to the dealership and they have a new guy named Evan who totally has his shit together. He actually came for a ride with me and got to hear the noise between 1st and 2nd shifts on a turn under power and from a stop going straight. He was pretty shocked.
So it also happened that a stellantis tech was there doing training and he brought it all with all the info from here and others to him.
A new star case was opened and apparently things are moving along!
What a change one new guy with experience in the service bay can make!
