Had a major issue with my 2019 G350d's transmission. Has anyone else experienced this?

My 2019 G350d's transmission has been exhibiting erratic behavior - slipping and hesitation during acceleration. The issue started about 5,000 miles ago and I've taken it to a dealer but they were unable to replicate the problem. Has anyone else experienced similar issues with their G350d or do you have any insights on what might be causing this?
