This may sound silly but... I've owned an xc 90 for 3 years.The question I have is about the small plastic button on the seat belt that goes around your waist. Many of my tops have very small holes in the front lower part of the garment. My daughter who is the only other person that either drives or rides in my Volvo also has tops with those small holes. At first I thought it was my washer. But after asking several of my friends we all agreed it must be something that rubs on the garment to cause those small holes. Like i said I've owned this vehicle for 3 years and I NEVER noticed that small plastic ? button on the seatbelt before. I think this is the cause of my dilema! Believe me I bet between my daughter and myself we have 30 tops with these HOLES! If anyone else has had this annoying issue please let me know!
