What’s going on with my Grand Cherokee?

Have a 2014 Grand Cherokee Overland, 111k miles only have had it for a year.

I notice when I’m backing out of a parking spot it feels like my jeep stops on its own mid turn, when I switch to drive and give it some gas the whole front end pops And feels like something in the tires/frontend is gonna break. but I continue driving just fine. It does it if I’m taking a sharp turn, turning into a drive way or drive thru. also, not as violently or as hard, it does it when I come to a stop and start accelerating again As well even if I’m not turning, this only happens at very low speeds. Almost like I’m driving over a speed bump or something. Not very good with cars so I’m trying my hardest to explain it well.

I would take it to the dealership but not sure if my powertrain warranty will cover whatever is wrong with it and really don’t have any money to cover the costs if not.

For a side note I also get a “service air suspension system immediately “ warning when hitting 40-60 mph and also a “service 4wd system” warning, which triggers the traction control light to flash on my dashboard. Stops when I turn the car off and no noticeable issues when these warnings pop up. Any help or advise is appreciated. Tried to get a video but of course it doesn’t do it when I try and show the problem.
