China Regulators Name Major Automakers Over EV Compliance and Parameter Discrepancies

China's Ministry of Industry and Information Technology (MIIT) has published findings from its 2025 production consistency inspection of new energy vehicles, citing prominent manufacturers for regulatory discrepancies. The violations include BYD plug-in hybrids exceeding declared fuel consumption in charge-sustaining mode, a Geely-affiliated electric sedan exceeding allowable wheelbase tolerance, and safety non-compliance in commercial vehicles from other domestic producers. In response, regulators ordered corrective measures, suspended certain model approvals, and called on the industry to curb irrational market competition.

The naming of major passenger and commercial vehicle manufacturers exposes production consistency vulnerabilities in fuel efficiency reporting, exterior dimensions, and safety hardware. This enforcement action signals that regulators are intensifying oversight over catalogue accuracy and supply chain quality control, reinforcing strict compliance standards amid intense industry price competition.

China's Ministry of Industry and Information Technology (MIIT) has publicly named several major domestic automakers for failing to adhere to mandatory production consistency standards across their new energy vehicle (NEV) lines, state media reported on August 28. The findings, stemming from the 2025 annual supervision checks conducted by the MIIT's First Equipment Industry Division, identified regulatory non-compliance across four primary operational areas: First, regulators identified documentation omissions and component discrepancies. Zoomlion's pure electric concrete mixer truck was found lacking user manuals and using tire suppliers inconsistent with its registered catalogue parameters, while Guangxi Automobile Group's electric refrigerated truck used an unapproved model of on-board real-time monitoring equipment. Second, sample vehicles failed exterior dimensional tolerances. A pure electric sedan produced by Zhejiang Haoqing Automobile Manufacturing Co., an affiliate of Geely, showed wheelbase discrepancies exceeding the state catalogue's allowable one-percent margin of error. Similarly, an electric power vehicle from Hebei Hongchun Special Vehicle Manufacturing Co. exceeded vehicle height tolerances. Third, fuel consumption parameters diverged from official filings. A plug-in hybrid sedan manufactured by BYD Auto Industry Co. recorded fuel consumption in charge-sustaining (CS) mode that exceeded the values declared in the company's official public catalogue filings. Fourth, several commercial vehicles failed national safety hardware requirements. An electric city bus from Foshan Feichi Automobile Technology did not meet net area requirements for emergency escape windows under standard GB 13094—2017, and an electric dump truck from Sichuan Nanjun Automobile Group violated standard GB 11567—2017 regarding side and rear underrun protective devices. In response to these non-compliance findings, the MIIT applied administrative penalties based on the severity of each case, including ordering mandatory rectifications, suspending or revoking affected vehicle catalogue approvals, and halting electronic certificate submissions for non-compliant models. An MIIT equipment industry official urged all motor vehicle manufacturers to learn from the cases, enforce admission management requirements, strengthen supply chain controls, and actively resist irrational market competition to protect consumer rights and maintain fair market order.
