2019 Grand Cherokee High Altitude swaying problem

Hello, I just purchased a 2019 HA. It has less than 200 miles. I was driving in the expressway today and my Jeep had a difficult time staying straight at higher speeds (60-80 mph). A few times the vehicle would pull to the left and even a slight correction to the steering wheel make the car over correct to the right. I did notice I had about 45 psi in the tires which is high as I learned they are supposed to be at 36 cold. I have read post on other site about bearing, shocks, etc but this is literally a brand new car. Any ideas? Thank you very much.

They fill to high pressure for transport, the dealer prep was suppose to correct that.

Sounds out of alignment or a defective/loose suspension component, have the dealer look at it. These jeeps do wander around a little more than the typical car, however. Wide tires, compliant suspension.

Is it possible you are feeling the lane keeping assist? Scared the hell out of my wife the first time she felt it in her Pacifica and although she insisted on every bell and whistle, she now turns everything off.

So I took the car back to the dealership today. They took some air out of the tires and advised me about the lane assist. I lowered the sensitivity of it so I will see how that goes. Thank you all for the suggestions.

There are actually a couple of different settings. You can adjust both the intensity of the correction feedback and sensitivity or early/late, of the warning. There is a noticeable difference between the settings.

33F, 36R. Look on the sticker on the door jam.

Geez, lane assist? I was going to say check toe in on front tires. My jamb says 33 psi front and rear.

Self driving vehicle! All these bells and whistles.

Jeep calls it laneSense. Between 37 and 112 MPH if the front camera can detect and "lock in" both sides of the lane, it will give you a bump back towards the center if you start to drift out of the lane unless you signal first. It actually works pretty good. I also have 33 PSI front and rear listed but a few more PSI in the front makes more sense.
