Maextro V800 brake pedal failures prompt Chinese regulatory scrutiny

Testing conducted by the automotive platform Dongchedi revealed that three Maextro V800 luxury electric MPVs experienced brake pedal bracket failures during emergency braking tests from 100 km/h. The failures occurred after multiple attempts, with the fractures reportedly preventing normal pedal operation and significantly increasing stopping distances from approximately 38 meters to 140 meters when emergency systems engaged.

Maextro, a luxury EV brand formed through a joint venture between JAC Group and Huawei, stated that no similar failures have occurred since deliveries began. The company announced plans to improve component design and offer free upgrades to existing owners. While Maextro cited third-party testing showing the components met industry standards, the discrepancy between those results and the real-world test failures remains a point of contention.

The incident has intensified the debate in China regarding ‘fast-track’ vehicle development, where manufacturers significantly compress production cycles to meet market demand. In response, four Chinese government departments, including the Ministry of Industry and Information Technology, have proposed new regulations to strengthen verification processes. The proposed rules would require environmental adaptation testing over at least one year—covering two winters and one summer—and mandate reliability testing of at least 30,000 km for new models starting in 2027.
