I just noticed tonight, there is a small tear between the crease on the passenger side rear seat and middle seat. About 1/2 inch long now. The rear seat is hardly ever used, and primarily just have car seat installed on passenger side rear seat. The car seat does not touch the area that has the tear now. Is this a defect that Volvo will repair under warranty? I don't see how the leather could have ripped or cracked, as the car is less than 2.5 years old.
