Tailgate problems of the 2018 Jeep Wrangler

My Jeep rubicon jl floats or drifts as I am driving it. It makes for a hard drive on long drives and I must look like I am driving drunk to others on the road. It is even worse in wind and it's windy a lot where I live. It was very scary to drive at first. I do not like it or feel it is safe at all. Having never owned a Jeep I thought it was just me or that the tires needed to be worn down a bit. The problem remains. While listening to fm/am stations the volume is wacky going low and high making for lousy listening. When the ac comes on on the higher setting my Jeep sounds like I am getting ready for lift off. Very loud. One lever on my seat near the headrest that controls the ability for a passenger to get in my two door almost immediately became detached and I don't even have my back seat in a lot so it doesn't get used a lot. I have an automatic and it does not shift smoothly. Today I pulled out of a parking spot and my Jeep surged forward faster than it should have and it often shifts poorly from park into drive and reverse. The sensor or heater electric wire on the inside of the tailgate window detached.
