My 2025 BYD Seal U DM-i, with only 6,000 kilometers, broke down during an intercity trip, leaving me deeply disappointed. The vehicle was first towed to the BYD Çavdarlı Authorized Service Center in Bursa, but since they couldn’t determine the cause of the malfunction, I had to arrange — at my own expense — to have the car transported to Mengerler Mercedes Ataşehir Service Center in Istanbul.
Despite my car being at the service center since September 13, 2025, for nearly 20 days, the source of the issue has still not been identified. The service team has only been experimenting with part replacements under warranty, without providing any definitive diagnosis. Due to the lack of technical expertise and experience at the authorized service centers, the problem remains unresolved, and parts are still being awaited from China. Throughout this entire process, no replacement vehicle or alternative solution has been provided, and my situation has been completely ignored. Moreover, the Bursa Çavdarlı dealership, where I purchased the vehicle, has not contacted me even once to provide an update or check on my case.
Even though my vehicle is still under warranty, I find this level of uncertainty and neglect unacceptable. I have been driving for over 30 years, and I have never experienced such poor after-sales service from any brand. Being stranded alone for six hours on a highway as a woman driver was extremely distressing and has severely shaken my trust in the brand.
My confidence in BYD has been completely broken. I refuse to accept the repaired version of this defective vehicle. Given the incompetent after-sales service and the emotional and financial harm I’ve suffered, I demand a full replacement of my car with a new one and expect my losses to be compensated immediately.
On Friday, August 29, while my 2025 BYD Seal was parked, another vehicle hit it, causing damage to the fender and bumper. On Monday, September 1, I brought the car to the Fiat Bilen BYD authorized service center in Toroslar, Mersin. The service team took photos, opened a case file, and asked me to b...
On September 16, 2025, my BYD Seal DM-i model vehicle was involved in an accident and was towed to the Mengerler Bostancı service center. Two days later, an insurance claim was filed, and the repair process began. After the expert report and insurance approval, the claim (file number 2025K70077) was...
On March 11, 2025, I handed over my BYD Seal DM-i vehicle to BYD Kar Service for repair. Today is April 7, and nearly an entire month has passed—yet I still haven’t received a clear update on when my car will be returned. The lack of transparency is unacceptable. During this time, I requested a rep...
On November 11, 2025, between 12:30 a.m. and 5:00 a.m., I experienced a very serious issue on the Istanbul European Highway with my BYD Seal U DM-i 2025 model vehicle. Even though the charging unit was at 25%, the car gave no warning or alert of any kind and suddenly came to a complete stop. The veh...
I purchased my BYD Seal U on May 20, 2025, and shockingly, by May 25, 2025—after driving less than 100 kilometers—the car started displaying a “check system” error. I immediately took the vehicle to the Koyuncu Konya service center, and since then, I have had to visit the service 3–4 times for the s...
