2025 Jeep Grand Cherokee Suspension Problems

I am unsure of what the complete issue is at this point. I have taken my car into two different dealerships multiple times and everybody keeps sending me back saying it’s running as it was designed. However, the things that’s experiencing it was not experiencing when I bought it, I would not have bought it And the list goes on. Has a random hesitation in the transmission. It revs way too high when shifting, it doesn’t downshift properly it doesn’t shift properly. There has been a groaning in the vehicle basically since day, one when downshifting it also howls when starting and sounds like a dieselThere is a very strange unstable feeling to the vehicle when traveling at pretty much any speed but when you get to the highway speeds, you feel very unsafe. It feels like you’re pulling a trailer, but you’re not as the best way I can describe it. This has been going on since about. I don’t know week five or six after buying the vehicle as I’ve stated I’ve taken it in multiple times. It wasn’t until I got the manufacturer involved that they’ve actually kept the vehicle and are apparently doing things… we’ll see. My reason for contacting is because I have driven a number of their loaner vehicles which were also grand Cherokee And at least half of them I was experiencing the same thing as I was in my own that seems to me like an issue…. the loaner I am currently driving I’m going to have them pick up with a tow truck because I don’t feel safe driving. It has not even half the miles on it than mine does and it’s worse than mine… to me that presents a problem. There are also weird electrical issues. The key fob doesn’t always let me in the door. I have to do it manually. It’s not communicating with the car. The gearshift just all of a sudden locks up and dash reads to put it in Park before I can put it into gear to proceed further. Sometimes the liftgate will not close. I have to do it manually and then it’ll catch the latch and pull down. I do feel there’s a safety is xxx
