BYD Seal U DMI Suspension Noise Not Fixed After 6 Months and Service Failures

I purchased my BYD Seal U DMI from Kar Servisi in Istanbul in February. From the very first day, I noticed a constant noise coming from the suspension. In March, I took the car to the service center, and they confirmed that the shock absorbers needed to be replaced. However, they scheduled the repair for April 25.
No reminder was sent for this appointment, so I missed it. Later, I was given a new appointment for July 24, but when I arrived, I was told that the part had been installed on another vehicle and was no longer available. Then, I was given an August 12 appointment, which I also missed, and afterward another one for August 18, which I again could not attend. Now, I have been told that the shock absorber replacement is being “evaluated by the head office” and that customers will only be contacted collectively if approval is granted.
This issue has been ongoing for 6 months, leaving me with an unresolved defect on a car that is still under warranty. The repeated delays, lack of reminders, and poor handling of my case have caused significant frustration.
I demand that the shock absorbers on my vehicle be replaced immediately under warranty and that BYD addresses the poor customer service I experienced with Kar Servisi. A new vehicle should not have suspension issues from day one, nor should customers be left waiting endlessly for a warranty repair.
