The Maextro V800, a luxury MPV developed by Huawei and JAC, is facing safety questions after Chinese automotive outlet Dongchedi reported brake-pedal assembly failures in testing. On a closed course, three low-mileage vehicles reportedly suffered broken pedal brackets during repeated stops from 100 km/h. The failures occurred on the second, third and fourth full-force braking attempts, depending on the vehicle; in one test, the pedal itself also broke.
Force-sensor readings differed substantially: one vehicle’s assembly failed at 1,612 N, while the highest recorded force before a failure was 4,589 N. Dongchedi compared the lower reading with a cited national requirement for brake pedals to withstand 2,000 N for five seconds. Its preliminary examination pointed to the pedal’s geometry and construction, including a relatively long distance from the pivot and limited support around that area. Inspectors also noted weld marks and thin material in stressed sections. These are reported observations, not a published official investigation finding.
The report said that after the foot brake failed, using the vehicle’s Park gear for emergency deceleration increased the stopping distance from about 38 metres to roughly 140 metres. The owner’s manual warns that this function cannot replace conventional braking. Maextro and JAC had issued no formal statement or investigation conclusion at publication. The V800 is priced from 766,000 to 1,016,000 yuan and is marketed with Huawei’s Tuling Longxing platform, an 800-volt active suspension and Qiankun ADS 5.0.
