2020 GMC Yukon — clunk when changing from reverse to drive — anyone dealt with this recently?

2020 GMC Yukon Denali, about 29,500 miles. There is a single clunk when changing direction at low speed, especially reverse to drive. No vibration while cruising. What would you inspect first: mounts, driveshaft play, differential mounts or CV joints? I am trying to get the facts straight before spending money. What would you check next?

If it were mine, compare a couple of chargers before blaming the 2020 GMC Yukon — site sharing and pack temp change the curve a lot.

One thing that mattered for me: I would not clear alerts before service can see them on the 2020 GMC Yukon.
