Peugeot Refused Warranty for My 2020 3008 GT Despite Ongoing Sound System Issues

The sound system of my Peugeot 3008 GT 2020 model vehicle turns off by itself and does not return for a while. When I took it to the authorized service, the amplifier was replaced, but the issue occurred again. Then, the tweeter on the right rear door was replaced, yet the problem persisted. Despite these repeated repairs, the root cause of the issue was never identified or resolved. Now, when I contact Peugeot Turkey, I am told that there is no warranty because I did not have the vehicle's maintenance done at the authorized service. If you are considering purchasing a Peugeot vehicle, it is something you should think about a thousand times, not just when buying a car.
