I purchased a BYD Seal U DM-i 2024, expecting a smooth, tech-integrated driving experience. Unfortunately, it’s been anything but that. Although I can log into the BYD mobile app, none of the remote features work because the in-car SIM card is not active. Since March, I’ve been going in circles between BYD Efe dealership and BYD headquarters, and no one has provided a solution.
The dealership keeps blaming the lack of a service update and pushes me toward BYD central. The support team at BYD only creates service tickets and tells me I “should be able to use the app,” but in reality, there is no multimedia update on my vehicle, and nothing functions.
It's beyond frustrating that such a basic, advertised feature remains unusable for months with no concrete response or timeline. I paid for a connected car experience and received none of it.
BYD must stop giving vague answers and take responsibility. I demand an immediate update and resolution. If this can’t be fixed soon, I expect compensation or the option to return the vehicle. This is not what I signed up for.

I purchased the BYD Seal U DM-i about a month ago. While I’m happy with the vehicle itself, the post-sale support and dealership service have been extremely disappointing. From day one, I have not been able to use the official BYD mobile app because my car is not linked or recognized within the app ...
I own a 2023 BYD Atto 3, and since 18 June 2025, the remote access feature has not been activated despite a SIM card being installed at the Diyarbakır Kardelen dealership. This issue has persisted for nearly two months. My car is still running on the initial software version, and because the version...
I purchased a BYD Seal Hybrid, and for the past month, the remote access system has not worked at all. Every time I contact customer service, they just tell me to wait two days or to uninstall and reinstall the app—which I’ve done multiple times with no success. I’ve called customer service repeate...
