NHTSA Complaint #11517940 — 2020 RAM 2500

Randomly (maybe twice a month) when I am stopped at a light (vehicle in drive with brake on) my truck will suddenly surge forward. The dash will say "Shift to park to start", but the truck is already started and running with brake only on. It would be possible to hit someone or something if the brake isn't fully down. I have notified the dealership and they state "NO PROBLEM FOUND AT THIS TIME" when I had it in for service. They are saying I would need to leave my vehicle with them so they can try and replicate it. Being this does not always happen, my vehicle could be with them for a long period of time and not sure how they would replicate it without driving it all day for days/weeks on end. I have had this issue for over a year. I just took my vehicle in for a 30,000 mile service which included a throttle body service. This particular service has not remedied the issue (if it were something to do with that).
