I am facing some nagging issues with my car and wondering if there's any hope: I feel some buffering pressure in my ears at speeds over 20 but my wife doesn't feel it and the service guys didn't either. It's subtle but I can't imagine living with it for the life of the car. There are no obvious gaps anywhere where I can feel the wind or anything but I just sense it. It's driving me crazy. My seat has some movement to it when I apply the brakes which I've never felt in any other car. Even stopping from low speeds and I feel it jerk forward slightly and then back. Again, they didn't feel it in service but still tightened the bolts and the issue remains. Is this normal? Should the seat move even a little when the car stops hard/semi-hard? The front left wheel grinds against something when turning all the way left. They fixed the alignment to "spec" to fix this but I still hear it. After the minor 153 update, the "jet engine" noise from the front motor has become too loud both in normal and sport mode. It's now a very prominent electric motor sound that I can hear at any speed and any acceleration, even when pulling out of the driveway in 15MPH zones. I remember hearing it only when I was punching it pre-153. Is this normal or should I have it looked at? My service center is far away and the whole getting a loaner, waiting days and then getting my car on a flat bed is just too much work and I don't want to go through it if these are "normal" issues and I have to just live with it. I went through that before, got a very dirty loaner and after all said and done, the car is just the way it was. They were not even able to fix a mis-aligned window chrome trimming that is so off that almost everyone notices and comments on it. Thoughts and experiences?
