2022 Nissan Qashqai Door Card Upholstery Peeling Off

I own a 2022 Nissan Qashqai, which I purchased from an official Nissan dealer about one year ago. In May 2026 the material on the door card started peeling away. This defect is clearly visible on the door panel and is continuing to get worse over time. I reported the problem to the Nissan dealer, but they showed no interest and stated that it was not their issue. I then contacted Nissan customer care, who said they would charge £165 just to diagnose the problem, even though the peeling is clearly a material or manufacturing defect on a relatively new vehicle that was bought from a Nissan dealer only a year ago. I find it unacceptable that I should have to pay a diagnostic fee for what is visibly a quality issue on a 2022 car. I am requesting that Nissan repair the peeling door card free of charge and take responsibility for this fault.
