BYD Seal U DM-i Making Loud Explosion Sounds Right After Delivery
On September 1, 2025, I purchased a BYD Seal U DM-i model vehicle from the BYD Derya DRC dealership. On the very day I took delivery of the car — during the introductory walkthrough — loud explosion-like sounds suddenly came from inside the vehicle. The demonstration was immediately stopped, and the car was taken to the service center. About an hour later, they brought it back, saying they couldn’t identify the cause of the issue and had only reset the system. Despite this, they delivered the car to me in a defective and unsafe condition.
Within just two days, the explosion noises became louder and more frequent while driving, posing a serious safety risk on the road. When I returned to the dealership, they took the car back into service, connected it to diagnostic equipment, and again stated that they could not detect any faults. Even though the issue persisted, they returned the vehicle to me in the same faulty condition and told me to record a video and bring it back again later. The indifference and dismissive attitude of the dealership and service staff made my situation even worse.
Just six days after purchase, while driving, the vehicle emitted extremely loud explosion sounds that nearly caused an accident and could have put my life in danger. Even after turning off the ignition, the sounds continued for about 30 minutes, and I was unable to reach anyone for help during that time.
I was forced to return the car to the BYD Derya DRC dealership, where it has now remained for nearly three weeks. During this entire period, I was not provided a replacement vehicle, and my request for a vehicle exchange was denied. I also had to rent a car at my own expense, suffering significant financial and emotional distress. When I contacted BYD Turkey’s distributor, no effective solution was provided, and their customer service response was extremely inadequate.
Although my vehicle is still under warranty, I am requesting that it be replaced with a new, fully functional car, or that the entire purchase price and related expenses (with interest) be refunded. I urge BYD to resolve this situation immediately and take responsibility for the serious safety risk and poor customer experience I have endured.
