Have 2004 XC90 with 30K miles. Noticed the driver side leather seat starting to crack. Bought it brand new and have taken good care of it. Took it back to the dealership because I thought it was not normal wear and tear and wanted warranty to cover it. Service manager told me that it was not unusual at all and that it happens regularly and the vast majority of other volvos that are 3 years old will have cracking leather seats. He claims it IS normal wear and tear. Has anyone else had this problem?
