BYD Warranty Support Failed After Serious Engine Noise Problem

On behalf of our company, we purchased a brand-new BYD Sual vehicle approximately 5 months and 20 days ago from the Antalya Yazıcılar Otomotiv BYD dealership.

When the vehicle reached around 4,000 kilometers, an abnormal noise started coming from the engine, so we immediately took the car to the authorized service center. At the service center, we were informed that the noise was coming from the camshaft area and that the engine would need to be opened and certain parts replaced.

After our vehicle remained in service for a full four months, we were informed that the parts had been replaced but that the malfunction still could not be resolved. We were then told that any future work related to the vehicle would no longer be covered under warranty.

When we asked what exactly the problem with the vehicle was, we were only told that water had been detected inside the vehicle, but they could not determine the exact source or nature of the malfunction. When we questioned why this supposed water issue had not been detected from the beginning and why the engine had been disassembled and parts replaced unnecessarily, we did not receive any satisfactory explanation.

In addition, the fact that water was allegedly detected only after the vehicle had already spent four months in service raises serious concerns and questions for us. Ultimately, the vehicle was returned to us still defective and unresolved.

After this experience, we sought another solution and contacted the BYD service center in İzmir. There, we were told that there were no technicians capable of repairing these vehicles properly and that Toyota technicians were handling BYD vehicles instead.

At this point, the brand-new vehicle we purchased is sitting unusable in front of our property, and it has not been possible to use the car safely or properly.

Because of everything that has happened, our primary expectation from the company is for our vehicle to be repaired completely, properly, and under warranty, and then returned to us in a fully functional, safe, and defect-free condition.

We urgently request the necessary technical and administrative support and expect our customer grievance to be resolved immediately.
