华为鸿蒙智行与江淮汽车联合打造的豪华MPV尊界V800陷入制动踏板安全争议。10月8日，汽车媒体懂车帝公布实测视频显示3辆新车在时速100公里紧急制动时踏板支架断裂123，事件曝光后江淮汽车股价跌停，收盘24.72元/股2，市值在3个交易日内缩水约122亿元3。
针对质量争议，江淮汽车随后公布第三方检测报告。报告显示，制动踏板可承受1500N纵向力且位移量在5毫米以内，符合行业标准QC/T 788-2018要求12，在加严检验至3000N纵向力条件下未出现裂纹和损坏12。
然而，负责检测的中国汽车工程研究院检测中心随即澄清了报告的适用范围。该机构明确表示"我们的报告只对企业送来的样品或者样车负责，对于企业后续批量生产的产品，我们不做任何保证"12。这一表态引发关注，两位汽车工程师随后指出检测存在3大疑团：是否模拟了急煞瞬间冲击、是否还原了动态驾驶场景、检测对象是否包括发生断裂的踏板支架1。截至目前，江淮汽车未对这些疑问作出回应。
The Huawei-JAC Motors luxury MPV Junxie V800 remains mired in controversy following a braking pedal defect that has raised serious questions about quality assurance and accountability. On October 8, automotive media outlet Dongchehe released test footage showing the brake pedal bracket fracturing on three vehicles during emergency braking from 100 km/h, prompting JAC Motors' stock to hit its daily limit down that same day at 24.72 yuan per share 2. In response, a third-party inspection report released on October 11 claimed the vehicle's braking system meets industry standard QC/T 788-2018, with the pedal capable of withstanding 1,500 newtons of force and maintaining less than 5 millimeters of displacement, and that it sustained no cracks even under a more stringent 3,000-newton test 2.
However, the testing institution's clarification has only deepened concerns about the vehicle's reliability. The China Automotive Engineering Research Institute's Testing Center, which issued the inspection report numbered 26-WT-DGJ-N10440, explicitly stated: "Our report is only responsible for the samples or test vehicles provided by the enterprise; we make no guarantees whatsoever regarding products subsequently manufactured in bulk by the enterprise" 1. Two automotive engineers have identified three major unresolved questions: whether the test simulated the impact shock of emergency braking, whether it replicated dynamic driving conditions, and whether the tested components included the actual bracket assembly that fractured during Dongchehe's demonstration 1. The Junxie V800 is priced between 766,000 and 1.016 million yuan 3, and the scandal has eroded JAC Motors' market value by approximately 1.22 billion yuan over three trading days 3.
