Huawei‑Backed Maextro V800 Brake‑Test Videos Pulled From Platforms | ChinaEVHome

New developments have emerged in the Maextro V800 braking incident, which drew widespread attention yesterday after brake pedal brackets broke during emergency braking tests of the ultra-luxury vehicle co-developed by JAC and Huawei.

ChinaEV Home found that, starting this morning, Dongchedi’s original V800 braking-test videos had been removed from multiple platforms, including Bilibili, Dongchedi’s own app and Douyin. The pages now show notices indicating that the content is unavailable or the videos have violated platform rules.

The removals have prompted different interpretations online. Some believe Dongchedi voluntarily withdrew the videos, while others suspect involvement by the automaker’s public relations team. Neither explanation has been confirmed, and the reason for the removals remains unclear.

The incident stemmed from emergency braking tests conducted by Chinese automotive platform Dongchedi on three new Maextro V800 vehicles at a closed test facility between October 1 and 4. The tests involved braking from 100 km/h to a complete stop.

The test footage showed the brake pedal brackets physically breaking on all three vehicles during full-force braking attempts—on the third, fourth and second attempts, respectively. After the brackets broke, the brake pedals detached, preventing drivers from braking normally with the pedals. The test vehicles had to rely on emergency measures, including shifting into Park.

Under normal conditions, the vehicles’ braking distance was approximately 38 meters. After the failures, it reportedly increased to around 150 meters. The three vehicles came from different production batches but suffered similar breaks at the same location, prompting the testing team to question whether the failures were isolated incidents.

On the evening of October 8, Maextro issued a statement saying its braking system had been developed and validated against requirements exceeding national and industry standards. The company added that no cases of brake pedal bracket base fractures had been reported in customers’ real-world use since the first vehicles were delivered.

Maextro also said it would further optimize the component design and offer existing owners a free upgrade option. It will conduct a systematic review of component design validation, testing limits and production quality management, making improvements where necessary.

Separately, a Chinese media outlet reported that a staff member at a Maextro dealership said Huawei and JAC would repeat the V800 braking tests and make the results public.

JAC shares continued to fall amid the controversy. As of publication, the stock was trading at RMB 22.75 ($3.40), down 7.97%, putting the company’s market capitalization at approximately RMB 51.283 billion ($7.66 billion).
