Issue with my Jeep grand Cherokee

I have taken my 2024 grand Cherokee 4x4 to the dealership 4 times for the same issue and they can’t seem to find the problem. It started at 20,000 miles. Was driving to work and the whole truck started shaking and check engine light came on. When I took my foot off the gas it stopped. Pulled over and turned it off. Restarted it and drove it to the dealership. They ran diagnostics and couldn’t find anything wrong with it. They ended up updating the system and it was fine for a bit. Since then it has happened 3 more times. Nothing shows up on diagnostic tests. What could this be from? I am tired of having to take it in with no fixes. I’m at a loss here. Help.
