You certainly have a case. I haven't seen many people confirming that all fixes were attempted. You're one of the first. I suggest you contact Hyundai Corporate. Your dealership should also open a case with Hyundai.We had all of the TSB fixes applied and it reduced the sound for about a week. Thereafter, the wind noise was back, including the whistling sound. The service center at the local Hyundai said that is all they can do based on the notices from Hyundai. We asked about replacing the door and the response was they don't have authorization from Hyundai for that as a fix. Perhaps more people will be needed to prove that the TSB fixes don't always work.
Also, there are those reports that Hyundai is no longer honoring the TSB, potentially because they have a better fix? That hasn't been confirmed, so maybe your dealership can get that info from Hyundai.
