Xiaomi is defending itself in court against allegations that it misled consumers regarding the performance benefits of an optional carbon-fiber hood for its SU7 Ultra electric vehicle. The case, heard in the Nanjing Qinhuai District People’s Court on November 20, 2025, centers on claims that the 5,900 USD hood—advertised for its airflow capabilities—did not deliver the promised cooling and efficiency improvements.
The Dispute: Performance vs. Reality
The controversy erupted after multiple SU7 Ultra owners and independent testers found the hood’s airflow benefits minimal in real-world conditions. Despite being marketed as functional for cooling wheel hubs, teardown analyses revealed the production hood’s internal design resembled that of a standard hood, with only slight weight reduction. This discrepancy spurred over 100 formal lawsuits and numerous consumer complaints. Xiaomi maintains that the hood was optional, and that early social media posts were promptly corrected, thus negating any intent to mislead.
Court Arguments & Legal Defenses
During the evidentiary hearing, Xiaomi’s legal team presented technical documentation, including wind-tunnel tests, to support the hood’s claimed performance. They argued that the hood wasn’t a required purchase and that any initial misstatements were swiftly rectified. However, plaintiffs’ attorneys and legal observers suggest these materials will be thoroughly scrutinized to determine if they validate Xiaomi’s promotional statements and whether the corrections were sufficient to prevent consumer confusion. The court deferred judgment, requesting further evidence from both sides.
Separate Ruling: Consumer Fraud Confirmed
Coincidentally, the Suzhou Intermediate People’s Court issued a second-instance ruling in a related case the same day. The ruling upheld an earlier judgment finding Xiaomi liable for consumer fraud in a separate instance, ordering the company to pay a single plaintiff 21,949 USD in refunds, damages, and legal fees. This award is specific to that individual case and doesn’t automatically apply to all plaintiffs.
Why This Matters
This legal battle is being closely monitored by automakers, consumer advocates, and regulators. The outcome will set precedents for evaluating marketing claims related to optional high-performance vehicle components, the evidentiary weight of manufacturer testing, and the available recourse for consumers in automotive disputes. The case is likely to influence how optional components are promoted and legally challenged within China’s rapidly expanding EV sector.
This case highlights the growing scrutiny of EV manufacturers’ performance claims, particularly concerning premium add-ons. The courts’ decisions will shape future marketing practices and consumer protections in the industry.
