MAEXTRO V800 Brake Failure: 3 Test Vehicles Snapped Pedals Under Emergency Braking
SingTao · 2 SOURCES1 day ago6 MIN
Summary
Chinese automotive media platform DongCheDi (懂車帝) revealed on October 8 that three MAEXTRO V800 ultra-luxury electric MPVs suffered brake pedal failures during emergency braking tests conducted from October 1 to 4. The pedals broke at approximately 1,600N of force—equivalent to peak braking force applied by an average-sized person in an emergency stop scenario. The vehicle's manufacturer, JAC Motors (江淮汽車, Shanghai stock code: 600418), saw its stock plunge for two consecutive sessions, losing roughly 117 billion yuan in market value. MAEXTRO acknowledged the issue while maintaining its braking system meets or exceeds national standards, and will offer free upgrades to affected customers.
Key Points
- MAEXTRO V800 is a joint brand between Huawei and JAC Motors, positioned as an ultra-large luxury MPV with official pricing ranging from 766,000 to 1,016,000 yuan
- Three test vehicles all experienced brake pedal breakage at the same location—the root of the pedal bracket's shaft—with nearly identical fracture patterns
- Engineering analysis revealed the pedal bracket was made of engineering plastic with only a single support plate at the shaft area, lacking the two-to-three reinforcement plates found in comparable models from AITO and Zhizhen (both also Huawei ecosystem brands)
- JAC Motors stock hit the daily limit-down circuit on October 9, closing at 22.75 yuan per share, down 7.97%, following a 62-billion-yuan loss the previous day
- MAEXTRO issued a statement on October 8 confirming free upgrades for delivered vehicles but has not addressed whether it will initiate a formal recall
Why It Matters
This incident exposes a potential quality-control gap in Huawei's expanding intelligent vehicle ecosystem, where the brand's "multiple redundancies" marketing claim appears contradicted by a component failing under normal driving stress. The rapid market reaction—117 billion yuan in evaporated value within two sessions—signals that investors are closely scrutinizing quality assurances in the ultra-premium EV segment, and any further safety reports could severely damage trust in the MAEXTRO brand just weeks after deliveries began .
