2021 kicks. I was driving along. Ac running. Dog in back seat wanting some fresh air. Rolled back window down about half way. All of a sudden I'm hearing this thumping louder and louder oh **** I've got a flat. Pull over no flat get back in car started drive holy crsp I keep hearing the very loud thumping I think it's coming from under the hood. Then I thought it was coming from the exhaust almost as if the car was struggling to go. Like draging. I rolled the window up to 1/4 open the noise stopped closed window no noise. Opened window again 3/4 down
The noise started up again almost like a shaking. Strange anyone know what's going on
Only had car 2 mo. I hate having to be inconvenienced to go to dealer

What your experiencing is called wind buffeting. It's a reaction of the outside air meeting the inside air at highway speeds. It is normal, all cars do it. For additional info on this, Google the term wind buffeting. Nothing wrong with your car.

I agree with Fral659. This is normal when opening only the rear windows at certain height.

I disagree not all cars do do this... as least not as loudly and car rattling as this company car does.... it's painful on the eardrums... impossible to drive with window open. Front and back windows!.... I've never had a vehicle do that before... glad I didn't buy it myself.

Just curious what vehicle does not do this as much? Thank you

Every vehicle I've has in the last 30 years has done it, some worse or louder than others, but still they have all done it.
