ChinaChinese car-information platform Dongchedi published a video on 8 October 2026 in which the brake pedal bracket broke on all three Maextro V800 MPVs it put through emergency-braking tests from 100 km/h to a standstill. Maextro, the luxury brand of Huawei and JAC’s HIMA alliance, responded the same day.
Dongchedi’s 100 km/h braking test
According to the video, the bracket on the first car fractured on its third braking attempt and the one on the second car on its fourth. Dongchedi then bought a third, new V800, and its bracket failed on the second attempt.
The testers said the foot brake could no longer be operated normally once the bracket broke, so they stopped the cars with the emergency braking function triggered through the Park control. The descriptions of the failures and of how the cars were stopped come from the testing team. No official investigation findings have been released.
Maextro’s bracket redesign and free upgrade
In a statement on 8 October, Maextro said it will improve the design of the brake pedal bracket base and offer existing owners a “free upgrade option”. It also said it will review and strengthen design validation, testing parameters and production quality management.
The brand said no bracket-base fractures have occurred in customer use since deliveries began. It said the braking system was developed and validated against requirements stricter than China’s national standards, and described the conditions in the video as “non-standard, extreme test conditions”. JAC’s shares closed down 10.01%, the daily limit, in Shanghai on 8 October.
Maextro has not announced a recall.
Upgrade timing and root cause not disclosed
The statement as reported does not say how many owners the upgrade covers, when the new part will be available or how owners will book it. The reports give no root cause for the fractures.
Maextro V800 price and launch
The Maextro V800, a range-extender MPV, went on sale in China on 5 August 2026 at 766,000-1,016,000 yuan (~$113,800–151,000).
