I have a 2019 Ram with less than 1,000 miles, and on 5 different occasions, the truck will not move when I put it in drive. The dealer can not replicate the problem since it happens randomly. There has been 2 failed attempts to fix the problem. Going in for a 3rd time to tmrw. Here is a video of what I am experiencing:

As stated. Under warranty. Show them the video. Make them give him a loaner and keep the truck until they fix it.
