On October 8, a testing video published by Dongchedi revealed a concerning issue: during a high-speed emergency braking test from 100km/h to a complete stop, the brake pedal brackets of three brand-new Zunjie V800 vehicles all suffered fractures. This malfunction rendered the vehicles unable to use the foot brake, forcing them to rely solely on the P-gear (parking gear) emergency braking system. In response to this incident, Zunjie Automobile's customer service advised the public to await further official updates and information.

The Zunjie V800 is a high-end luxury MPV, boasting a price tag in the million-dollar range. It represents a collaborative effort between Huawei and JAC Motors and is slated for market release in August 2026. Following the dissemination of this news, JAC Motors' stock price experienced a significant decline, hitting the daily limit during trading sessions.
