Mine does and it's driving me crazy. I try to unlock the seat belt but it sticks sometimes and it's getting annoying. I'm going to take it to my local dealer but I was wondering if anyone here has had the same problem. Strange too, it doesn't change even if it's hot or cold both inside or outside of the car.

 

Mine just started doing the same thing. I think it may just be the spring inside the seatbelt unit. I believe this should be covered under the basic warranty. Let me know what you find out.

 

Had an 04 mazda 3 and it did it so bad i stopped wearing it lol but i traded the car in for an 07 3 Problem solved.
