Chinese automotive outlet Dongchedi reported that the brake-pedal support broke on three separate Maextro V800 minivans during testing. In a 100-to-zero km/h braking evaluation, the plastic structure holding the pedal failed; the vehicles then rolled several metres while slowing with regenerative braking. The test included several other models, among them the Porsche Taycan, Mercedes-Benz S-Class, Zeekr 009 and Xpeng P7.
The V800 is a high-end Maextro model, a brand developed by JAC and Huawei. Its advertised technology includes an 800-volt electrical architecture, four-wheel steer-by-wire, active suspension, more than 40 sensors and five lidar units. The repeated failures have drawn attention to the contrast between the vehicle’s technology and the reported weakness of a safety-critical component.
After videos of the tests circulated online, JAC’s shares reportedly dropped 10%. The article says the videos were censored on the third day after going viral. Reuters reported that China’s Ministry of Industry was pursuing an investigation with regulators. Maextro and JAC have publicly acknowledged the issue and said they would cooperate; the article says no recall had been announced at the time of publication.
The incident comes as China is tightening expectations for vehicle quality, safety homologation and durability, including requirements for manufacturers to address defects through recalls. Huawei is JAC’s partner on Maextro, a luxury marque positioned to compete with established premium brands.
