Maextro brand from Huawei and ex-Nio manufacturer JAC responded to the brake pedal failure of its V800 luxury minivan with a price of up to 1,016,000 yuan (151,540 USD). A previous video from Dongchedi Chinese media revealed that brake pedal brackets fractured during braking on three separate occasions.

We will remind you that three Maextro V800 minivans were tested by the Chinese outlet in an emergency braking test from 100 km/h. This scenario isn’t considered “extreme”, as a lot of drivers actually encounter it during high-speed driving. So, such a failure puts the whole car’s safety at risk. It also questions the testing phase and the quality control of the Maextro brand, as well as the requirements of the Chinese regulators.

Dongchedi officials added that the actual peak force applied to the braking process reached 1,612 N. However, it dropped rapidly after peaking. The representatives of the outlet highlighted that the screenshot from a video with a “4,589 N” figure was a visual artifact caused by a mismatch between the camera’s frame rate and the LCD screen of the equipment. So, there was no “abusive testing.”

This really questions the quality of the JAC-made Maextro V800 minivan. It is a 5495 mm car with seven seats in the cabin and a gross weight of 3,800 kg. It is filled with high-end features like steer-by-wire tech, a built-in coffee machine, a 41.6-inch retractable projection screen, a 41-speaker sound system, an 8-liter refrigerator, and gesture-operated windows. This luxury driver also comes standard as an EREV with a 65 kWh ternary battery from CATL, two electric motors for 390 kW (523 hp), and a 1.5-liter ICE that works as a generator. And yet it failed to have a durable brake pedal.

Dongchedi officials noticed a few issues with the brake pedal. They include the centre of the brake pedal located 130 mm from the pivot axis, a single layer of vertical support at the pivot area, and insufficient reinforcement ribs. A combination of those factors led to a systematic failure.

According to Maextro officials, the brand will optimize the design of the brake pedal and offer a free upgrade option to existing owners. They will also review the design validation, testing parameters, and production quality management for the relevant components.

However, the automaker highlighted that the V800 testing process “exceeded both national standards (GB 21670‑2025 / GB 7258‑2026) and industry standards (QC/T 788‑2018).” There have also been no instances of brake pedal bracket base fractures during user operation since the delivery of the initial batch of vehicles. Maextro handed over 181 units of the V800 minivan to owners in August 2026, according to China EV DataTracker.
