Tesla Accused of Misleading European Regulators on Self-Driving Safety Data

June 18, 2026 — David Chen 4 min read

Tesla presented misleading safety data about its Full Self-Driving system to European regulators, according to an exclusive report published Wednesday. The automaker allegedly submitted figures that understated crash rates and overstated driver intervention frequency, according to people familiar with the matter. Regulators in Brussels are now examining whether the data influenced approval decisions for the advanced driver assistance feature across the European Union.

What Tesla Submitted to Regulators

Internal documents reviewed by investigators show Tesla characterised its Full Self-Driving system as performing significantly better than internal testing indicated. One document, dated March 2024, listed a disengagement rate that was roughly 40 percent lower than figures recorded by Tesla's own engineering team. The company submitted these figures to the European Union's regulatory body responsible for vehicle type approval. Brussels-based officials have confirmed the investigation is active but declined to specify which documents are under review.

The discrepancy has alarmed safety advocates who worry that regulators may have approved the technology based on incomplete information. European road safety statistics show more than 20,000 fatalities occur annually on EU roads, a figure that safety groups argue makes accurate data-sharing essential. If regulators discover that approval was influenced by faulty data, existing certifications could face suspension.

Regulatory Response in Brussels

The European Commission confirmed it has opened a formal review into Tesla's submission process. A spokesperson told reporters the body is working with national type approval authorities in Germany, France, and the Netherlands. These three countries host the manufacturing and testing facilities most directly connected to Tesla's European operations.

The review could take months to complete. Under EU law, regulators have up to 18 months to reach a determination once a formal investigation begins. However, sources familiar with the process suggest officials may attempt to accelerate the timeline given the safety implications. If violations are confirmed, Tesla faces potential fines of up to 30 billion euros, representing roughly 10 percent of its global annual revenue.

Investor Reaction and Stock Movement

Tesla shares fell more than 5 percent in after-hours trading following publication of the exclusive report. The decline wiped approximately $35 billion from the company's market capitalisation within hours. Institutional investors have begun reassessing positions, with at least two major US-based pension funds confirming they are monitoring developments.

Analysts on Wall Street issued mixed assessments. Morgan Stanley analysts wrote in a note to clients that the investigation poses "material regulatory risk" but stopped short of revising their price target. Goldman Sachs, meanwhile, flagged potential disruption to Tesla's European launch schedule for its next-generation autonomous features. Both firms have existing buy ratings on Tesla stock, though Goldman analysts suggested the company may face delayed regulatory clearances in key markets.

Full Self-Driving Remains Controversial

Tesla's Full Self-Driving system has faced scrutiny across multiple jurisdictions. The National Highway Traffic Safety Administration in the United States has opened more than 30 investigations into Tesla crashes involving the technology since 2021. European regulators have historically taken a more cautious approach, requiring more extensive documentation before granting approvals for advanced autonomous features.

Consumer advocacy groups argue the European investigation validates long-standing concerns about Tesla's transparency. The European Transport Safety Council, a Brussels-based organisation, published a statement calling for mandatory data sharing requirements for all autonomous driving systems. "Without independent verification, we are relying on manufacturers to tell the truth about their own products," the council stated.

Impact on European Business Operations

Tesla operates a major manufacturing facility in Grünheide, Germany, which produces vehicles for the European market. The factory employs approximately 12,000 workers and has been central to Tesla's strategy for reducing logistics costs and import tariffs. Any regulatory action affecting the company's ability to sell vehicles with Full Self-Driving features in Europe could complicate production planning at the site.

Suppliers in the European automotive sector are also watching the situation closely. Several German component manufacturers rely on Tesla contracts for significant portions of their revenue. Industry executives speaking on background expressed concern that prolonged uncertainty could lead to order cancellations or renegotiation of supply agreements.

What Happens Next

Regulators have requested additional documentation from Tesla, with a deadline set for late next month. The company has indicated it will cooperate fully with the investigation. Tesla's legal team has argued that its submission methods comply with existing European regulations, though acknowledging that data collection methodologies may differ from regulatory expectations.

Watch for the European Commission's preliminary findings, expected within the next quarter. Those findings will determine whether the investigation proceeds to a full enforcement action or is resolved through administrative review. Either outcome will likely influence how other automakers report autonomous driving performance data across the 27-member EU bloc.
