Recurring Shutdown Issue With My iPhone 14 Plus

I purchased an iPhone 14 Plus 128 GB in 2023 through CarrefourSA. Since the first days of use, I have been facing a recurring problem that has not been permanently resolved for about three years and has now become completely unacceptable. Every time a new system update is released for my phone and the update is installed, the device locks itself, shuts down and becomes completely unusable. This situation has been repeated at least six times in the last three years. The first time this problem occurred, my phone was still under warranty, and on 30.01.2026 I applied to the authorized service at Apple Zorlu Center Istanbul. Despite this, no permanent solution was offered to me. Each time, the device was only reset to factory settings and returned to me with a temporary solution. During my visits, I was told by Apple support that no problem was found in the tests, yet the device continued to repeat the same error in every update cycle. I am extremely tired of constantly having to reset my phone, facing the risk of losing my data and going through the same stress with every update period. This chronic malfunction, which should have been resolved under warranty from the very beginning, has been carried to the present day with makeshift methods instead of being handled seriously. I kindly request that a permanent and customer-oriented solution be provided without any further loss of time. I no longer accept temporary measures such as resetting the device to factory settings. Due to the chronic and recurring nature of the problem, I request that my iPhone 14 Plus 128 GB be replaced with a fault-free device and that this recurring issue be finally resolved.
