Recurring A/C Failure in BMW Leading to Medical Emergency

Dear Sir/Madam, I am writing to formally raise a serious concern regarding a recurring technical failure in my BMW 1.18, which has now escalated into a life-threatening incident for a family member. Despite repeated visits to Borusan İstinye service center, where I specifically reported the issue of the air conditioning system shutting down during long-distance drives in summer, the problem persists. I was informed that the vehicle’s system had been updated and the issue was resolved. As a customer who consistently chooses your authorized service center for all scheduled maintenance, particularly before long trips, I expected full reliability. However, last Sunday, while driving back from Ayvalık under extreme summer heat, the A/C system once again failed. As a direct result, my mother suffered a heat-induced medical emergency and this time, a heart attack. We barely managed to reach the hospital in time, and she narrowly survived a fatal outcome. This is not simply a technical malfunction — it reflects a profound failure in service responsibility and risk management. The fact that a global automotive brand is unable to address and resolve a core operational failure, despite all due maintenance having been completed at an authorized center, is both unacceptable and inexcusable. I wish to state unequivocally that I will be selling the vehicle at the earliest opportunity and will no longer consider BMW as a brand I can trust. Furthermore, I intend to pursue legal action against Borusan İstinye and will be sharing this matter with the media. I expect an immediate and thorough investigation, as well as a formal response. Sincerely,
