I think you are forcefully making yourself feel bad without much reason. As others have pointed out, this car gets glowing reviews all over the place. Every vehicle has its weaknesses including Hondas and Toyotas, the benchmarks in reliability. I would approach it more from a point of its superiority compared to other vehicles. Besides wind noise, what else do you feel is substandard? And I am sure, at one point, either Hyundai or somebody more clever than them, will come up with a solution to that.
I am still firmly planning to get the Palisade after my current lease runs out as there really isn't anything else which comes close to what these vehicles provide at their price point. And if, at that point, there still are noise problems, I will have a shop spray the inside of doors with rhino skin, foam or similar material.
