A wave of AI-generated misinformation has triggered a coordinated legal response from major electric vehicle (EV) manufacturers in China. Following the viral spread of false claims alleging that regulators had summoned several automakers for investigations into “battery lock” software features, companies including BYD, Tesla, Nio, Xpeng, Zeekr, GAC Aion, and Li Auto have issued formal denials.
The controversy highlights a growing tension between consumer anxiety over software-controlled battery performance and the rapid spread of unverified digital content. While the specific rumors were debunked by the manufacturers, they stem from a genuine and significant rise in consumer complaints regarding how over-the-air (OTA) updates affect vehicle range and charging capabilities.
The Origin of the False Narrative
The dispute began when social media platforms were flooded with posts claiming that Chinese regulators had interviewed eight new energy vehicle companies following consumer complaints. These posts alleged that three automakers had been formally investigated and that two companies had withdrawn software update packages.
According to reports from the Shanghai Observer, the misinformation campaign relied on altered screenshots and AI-generated lists. State-affiliated media noted that certain automotive social media accounts had reposted and modified earlier, unrelated coverage to create a narrative of widespread regulatory crackdown.
The automakers moved quickly to distance themselves from these claims:
- BYD labeled the reports as “pure rumors” on May 9, stating it had collected evidence to pursue legal action against accounts spreading false information.
- Xpeng’s legal department pointed out that AI applications were used to fabricate lists including the company, noting no such notices were received.
- Tesla representatives told Chinese media that the reports were inaccurate, emphasizing that all software updates undergo rigorous testing and filing procedures before release.
- Nio, Zeekr, and GAC Aion also issued statements confirming they had not been involved in any regulatory talks or investigations.
Understanding the “Battery Lock” Controversy
While the regulatory summons were fake, the underlying issue—so-called “battery locks”—is real and increasingly contentious. This term refers to practices where automakers use OTA updates to adjust charging limits, discharge depth, or power thresholds.
Manufacturers typically justify these adjustments as necessary safety measures to preserve battery health and prevent thermal issues. However, critics and some consumers argue that these software changes can artificially reduce vehicle performance and driving range, effectively degrading the product after purchase.
The scale of consumer dissatisfaction is significant. Data cited by Chinese media indicates that China’s national 12315 consumer complaint platform received over 12,000 complaints related to OTA battery-lock issues in March 2026 alone. This represents a 273% year-on-year increase, signaling a sharp escalation in user concern regarding software-defined vehicle capabilities.
Context: Heat, Charging, and Market Pressure
The timing of these rumors coincides with broader industry discussions on EV charging behavior and battery management. Public scrutiny intensified earlier this week during a livestream test of BYD’s megawatt flash-charging system, which recorded a battery temperature of 76 °C. This incident sparked online debate about battery heat management and the physical stress placed on cells during ultra-fast charging sessions.
These technical concerns are unfolding against a backdrop of shifting market dynamics. Despite the controversy, sales data for March 2026 shows mixed results for key players:
- Tesla China reported domestic retail sales of 56,107 vehicles, a 46.9% increase from February but a 24.3% decline year-on-year.
- Tesla’s market share in China stood at 3.4% in March, reflecting intense competition in the world’s largest EV market.
Conclusion
The recent wave of rumors serves as a cautionary tale about the intersection of AI-driven misinformation and legitimate consumer grievances. While the specific claims of regulatory summations were false, the 273% surge in complaints underscores a critical challenge for the EV industry: maintaining transparency and trust as software updates increasingly dictate hardware performance. As manufacturers defend their reputations against digital fabrications, they must also address the growing consumer demand for clarity regarding how battery management systems are optimized and controlled.
