BYD commented on the incident involving the Tang crossover, a video of which quickly spread on Chinese social media. In the footage, the car was driving through a flooded street, dragging its rear electric drive, which led users to ironically write that the crossover "gave birth" to an electric motor.
In a phone comment to Langzhang News, BYD representatives stated that the incident was caused by a strong impact of the undercarriage with an object hidden underwater. According to the company, an analysis of operational data and the nature of the damage to the mounts showed that the rear electric drive was torn off precisely due to mechanical impact. BYD emphasized that the incident is not related to a manufacturing defect or design flaw.
Notably, just a few days before the incident, BYD Executive Vice President He Zhiji warned car owners not to perceive the high level of battery protection as permission to overcome deep flooding. Although Blade Battery batteries comply with IP67 and IP68 protection standards, this only guarantees the high-voltage system's resistance to water exposure under specified conditions, but does not protect the car from mechanical damage to the undercarriage when colliding with hidden rocks, curbs, or other obstacles.
The company has already contacted the car owner and arranged for a technical examination. As of now, a written report on the results of the inspection has not been published, and the only official explanation remains the BYD customer support comment.
The incident serves as a reminder that even modern electric vehicles with a high degree of moisture protection are not designed for driving in deep water, where the main risk is not water penetration, but hidden obstacles that can damage power units and suspension components.
