2014 BMW 3.16i Msport Chronic Thermostat Problem And Block Plug Problem

 I am driving a BMW brand 3.16i msport 2014 model vehicle... My vehicle is at 79 thousand km yet. However, I would like to express my complaint, which I see as a chronic problem even though it has very low mileage, and which I have asked/ seen on all the internet site, forums and some masters. There is a problem with the thermostat of the car. Sometimes the warning lamp is on, sometimes I see it, sometimes I don't. I think that there is no balancing in the temperature of the engine. In this case, it means that I will have a problem with the engine in my vehicle in the future. Since this is a chronic problem and it is not user error, I request a replacement of this part in the service. Since the replacement of this part from the service is chronic, I expect it to be met free of charge. If necessary, I can write to Germany and BMW-based officials. My vehicle is registered to İstinye Borusan. I have no doubt that they will always be supportive. Thanks. As a note, the block plugs of the vehicle should not crack at low km in such a short time, etc. In this case, I think that it is chronic, and I request you to take the necessary action. I am waiting for your support on 2 issues.
