Why the Maextro V800 Brake Pedal Is Suddenly Everywhere

Why it’s suddenly everywhere

1. 01

   On October 8, auto media outlet Dongchedi released a closed-course test in which three brand-new Maextro V800 MPVs each fractured a brake pedal bracket during 100–0 km/h emergency braking — the third car lost its foot brake entirely and had to be stopped with the electronic parking brake.

2. 02

   Maextro’s own statement that night called the test a “non-standard extreme condition” yet promised a redesigned part and free upgrades for delivered cars — customer service later told media the fix rolls out from November and is “definitely not a recall.”

3. 03

   JAC Motors, Huawei’s manufacturing partner on the brand, hit the daily 10% limit-down on two consecutive trading days, erasing about 11.8 billion yuan in market value.

4. 04

   Within 48 hours the China Automotive Technology and Research Center sent automakers an urgent survey on brake pedal materials, focusing on non-metal parts — a move the industry reads as preparation for a regulation update.

The timeline

1. 2024-11Maextro debuts

   Huawei’s HIMA alliance and JAC unveil Maextro (尊界), the fourth and most expensive of Huawei’s co-developed car brands, aimed at the ultra-luxury tier.

The backstory

What actually broke — and why three in a row matters

The Dongchedi test was simple to describe and brutal to watch. Three low-mileage V800s, each performing repeated full-force stops from 100 km/h. The first car’s bracket broke on the third stop, the second car’s on the fourth, and a third car — bought new after the first two failures — broke on its second attempt. According to the test team, the third failure severed the pedal itself: the mechanical foot brake was gone, and the driver had to hold the electronic parking-brake switch to stop. Dongchedi’s follow-up testing reportedly found stopping distance stretched from about 38 meters to roughly 140 meters on parking brake alone.

The engineering autopsy spread just as fast as the video. The bracket is a glass-fiber-reinforced plastic (PP+GF40) part — a material used across the industry, including on sibling HIMA brands. But teardown images circulated showing that where the pivot area of comparable models uses two or three reinforcing ribs, the V800’s stressed zone appeared to rely on a single support plate. The counterpoint matters too: in the same test program, eight other models — including cars from HIMA siblings Luxeed and Aito’s orbit, Porsche and Li Auto — each survived six full-force stops at pedal forces averaging above 1,600N. Three cars, same spot, same fracture shape: repetition is what turned a test clip into a safety story.

The number that wasn’t: 4,589N

The first online defense of the car was a screenshot showing a pedal-force readout of 4,589 newtons — superhuman leg strength, proof of abuse. Dongchedi explained it as a ghost image: the high-speed camera and the sensor display refreshed at different rates, stacking digits into one frame. The real peak, it said, was 1,612N — which sits in an awkward middle ground. China’s mandatory standard GB 21670-2025 only requires braking performance with pedal forces between 65N and 500N, while the recommended industry standard QC/T 788-2018 asks a pedal to survive 1,500N for five seconds, five times, on a bench. The V800 broke at loads just above that recommended line, in a dynamic whole-vehicle scenario no standard directly covers. That gap — legal yet broken — is exactly where the public argument now lives.

A brand with everything to lose

Maextro is not just another car badge. It is the top of Huawei’s HIMA portfolio and the centerpiece of JAC’s attempt to climb out of the mass market — a strategy the state-owned automaker has staked heavily on while posting seven consecutive quarterly losses. The S800 sedan had given the partnership real momentum, outselling legacy flagships in China’s 700,000-yuan-plus segment. The V800, barely six weeks into mass deliveries, was supposed to extend that story into the luxury MPV segment. Instead, one video erased 11.77 billion yuan of JAC’s market value in two sessions, and rival executives spent the next day posting photos of their own all-metal pedals — BYD’s Yangwang cited a 2,500N in-house standard, GAC Honda claimed its Accord pedal survives 3,000N. In China’s hyper-competitive auto market, a rival’s bad week is everyone else’s marketing week. The pressure is broader than one viral test: BMW’s voluntary exit plan shows a legacy premium brand shrinking indirect roles as Chinese sales and margins come under strain.

What happens next

Maextro’s answer is a redesign without the word \u201crecall\u201d: an optimized bracket for cars not yet shipped, and a free, optional upgrade for delivered ones starting November. Weibo CEO Wang Gaofei publicly suggested the more confidence-building route — pause deliveries and audit the test-bench records. Meanwhile the regulator-adjacent CATARC survey on non-metal pedal assemblies signals the incident may outlive the news cycle as a standards question. There is precedent: in 2020 Ford recalled over 38,000 Mustangs in the US and 2,627 in China for a pedal bracket that could snap under emergency braking — a defect found with zero field failures reported, just as Maextro emphasizes today. The lesson Beijing and Hefei are both weighing is that \u201cno complaints yet\u201d has never been the same as \u201cno problem.\u201d

What people are saying

Common questions

Is the Maextro V800 being recalled?

Not in name. Maextro calls it a free upgrade: redesigned brackets will go into cars not yet shipped, and current owners can book a no-cost replacement starting November 2026. Customer service has stressed the upgrade is optional, which also means owners who never hear about it keep the original part.

Was the test rigged with superhuman force?

The viral 4,589N screenshot was a camera ghost image, per Dongchedi; the real peak was 1,612N. That exceeds the 1,500N bench-test load in the recommended industry standard QC/T 788-2018, but eight other models survived six stops each at average forces above 1,600N in the same program.

Are plastic brake pedals normal?

Glass-fiber-reinforced plastic pedal brackets are used industry-wide, including on other HIMA models that did not fail. The argument is about geometry and reinforcement — the V800’s pivot area appeared to use a single support plate where siblings use two or three — not about plastic per se.

Why did this hit JAC’s stock so hard?

JAC has bet its upmarket future on Maextro while posting seven straight quarterly losses, and the stock had just rallied on Huawei-Stellantis cooperation talk. The two limit-down days erased roughly 11.8 billion yuan — the market pricing in what a safety scandal costs a two-month-old luxury brand.
