BYD Atto 3 Roof Rust Started Under Antenna and Warranty Was Denied

I purchased my 2023 BYD Atto 3 as a brand-new vehicle from the Kar dealership in Istanbul in November 2023. After taking delivery, I had the entire vehicle covered with PPF. Approximately two months ago, I noticed a rusting and paint peeling problem on the roof, starting from underneath the antenna and spreading outward. The rust and paint damage are only visible on the roof and around the antenna.

During a phone conversation with BYD representatives, my vehicle was not physically inspected. Instead, the issue was assessed solely based on the photos I provided, and I was told that the problem was caused by the PPF and therefore could not be covered under warranty. I do not accept this explanation because I was never previously given any clear warning, restriction, or instruction stating that applying PPF to the vehicle would result in the warranty being voided or excluded. I do not believe it is fair to determine, without any detailed technical inspection and simply by looking at photographs, that the rust starting underneath the roof antenna was caused by the user and to place responsibility directly on me.

I believe that determining whether this type of rust was caused by a manufacturing or installation defect can only be done through an on-site and impartial technical inspection. As a customer of an international brand like BYD, I expect my vehicle to first be physically and thoroughly inspected, the source of the rust to be established based on technical findings, and, if a manufacturing or installation defect is identified, the defect to be repaired under warranty.

I request that my situation be resolved, that the problem with my vehicle be taken seriously, and that the warranty decision be reconsidered based on concrete technical findings. I believe customer satisfaction is achieved not by assigning responsibility to the customer without conducting an inspection, but by standing behind the products and addressing legitimate problems. I therefore expect BYD Türkiye to take appropriate action regarding this matter.
