Mine doesn't bother me much either. It's pretty quiet, and I can only hear it when I'm getting into/out of the car, or shifting in my seat. Once I settle into position for the drive, I don't hear it at all.
Regardless, the next time I have a reason to bring the car in for service, I'll request the seat TSB when I make the appointment. But that might not be for many months--the car is running perfectly, and I do my own service, so I don't know when it'll be there next.
