Audi A3 Seat Stitching Tore Apart After Only 7 Months

My Audi A3, which is only 7 months old and was purchased brand new, has developed torn stitching on both the front right seat and the rear left seat completely on its own. Despite using the vehicle extremely carefully and responsibly, the seat stitching opening up in such a short period of time clearly appears to me to be a manufacturing or chronic quality defect.

I have been struggling with this issue for approximately 3 months. Regarding the problem, I applied to the authorized Kartal Doğuş Otomotiv Audi service center. Initially, even the service staff could not provide a clear explanation and stated that they would consult Audi Germany for further evaluation. However, I was later informed that Audi Germany gave a negative response and that the issue would not be covered under warranty.

I absolutely do not accept that torn seat stitching in such a new and carefully maintained vehicle can be classified as user error or excluded from warranty coverage. Seat stitching in a premium vehicle should not fail under normal use conditions within only a few months of ownership.

I request that Audi provide a free repair or, if necessary, a complete replacement of the affected seat sections under warranty coverage for what I strongly believe is a clear manufacturing-related defect.
