Just to give an update. Regarding my 2 creaking issues:
1) Steering column/wheel
Yesterday they came (mobile device) and replaced my steering wheel. He said there’s been a slight design change in the steering wheel assembly. I had version 3. And now I have version 5. So far it seems to have resolved the creaking I was hearing. Although its only been one day so far.
2) Rear shelf, behind the rear seat.
The tech lifted the rear shelf and discovered a black plastic bracket that should be attached to the shelf, he noticed it came off. Thus it wasn’t securing it to the body. He ordered a replacement rear shelf. When it arrived at the SC, they’ll come back and replace mine. Likely 2-3 weeks.
