my 2017 ram jumps out of park several times service dealer brushes me off
Being a significant safety issue for which Chrysler was already sued when their Jeeps did that and people got killed, I would think they would take you more seriously. Use your parking brake until it's fixed. I think it's time to call and write a registered letter to the district office for help. They may take it more seriously when documented.
