Mercedes C200 Continuous Engine Issues Despite Repairs

"Update: I Still Haven’t Received a Positive Response to My Complaint Although I have contacted Mercedes-Benz Gelecek Otomotiv Diyarbakır Authorized Service and the relevant authorities regarding the issue of the headlight replacement, which was previously approved under warranty but later rejected (the details of which I shared in my initial complaint on 07.04.2025), I still have not received a satisfactory, solution-oriented response. Despite the time that has passed, I have only been offered a discount. However, there has been no official, written explanation as to why a process previously accepted under warranty was later made chargeable. I would like to reiterate that I reserve my legal rights under Consumer Rights, that my grievance continues, and that I expect the Mercedes-Benz brand to address the process seriously and provide a solution. If the issue is not resolved; - I would like to state that I will initiate application processes with the Consumer Arbitration Committee, - Mercedes-Benz Turkey Headquarters, - And, if necessary, with the relevant legal authorities. I would like to point out that one of the main reasons for being a Mercedes-Benz customer is my trust in the premium quality service of the brand and my belief that I would not be subjected to such grievances. However, the reluctance to resolve this issue is turning the premium perception into disappointment. I expect a global brand like Mercedes-Benz, which values customer satisfaction, to address this situation urgently with an understanding that prioritizes customer satisfaction."
