Fallos en el diseño de las puertas de Tesla: Una amenaza que se avecina para la confianza y la valoración de la marca

Tesla's door mechanisms, once celebrated as a hallmark of minimalist innovation, have become a focal point of regulatory scrutiny, legal battles, and reputational risk. The company's reliance on electrically controlled, flush-mounted door handles-designed to eliminate mechanical components-has exposed systemic safety flaws that could reverberate through its long-term valuation. As investigations intensify and lawsuits mount, the balance between design ambition and occupant safety is being tested, with implications for Tesla's brand trust and liability exposure.

Systemic Design Flaws and Safety Risks

Tesla's door design prioritizes aesthetics and automation over redundancy, a choice that has drawn sharp criticism. The electric door handles rely on a low-voltage battery, which can fail during collisions or power outages, leaving occupants unable to open doors from inside or outside the vehicle according to a Bloomberg investigation. This flaw has been linked to at least 15 fatalities in the U.S. over the past decade, including a 2016 Model S crash in Wisconsin that killed five people. In that case, plaintiffs alleged that the rear door's mechanical release was obscured and unfamiliar to passengers, exacerbating the tragedy.

According to a Bloomberg investigation, over 140 consumer complaints have been filed with U.S. regulators since 2018, detailing incidents where door failures trapped individuals in vehicles, including children. Tesla's design chief, Franz von Holzhausen, has acknowledged the problem, stating the company is working on a hybrid system that combines electric and mechanical release mechanisms. However, critics argue that Tesla has been slow to act, despite internal warnings dating back to the Model 3's development in 2016.

Regulatory and Legal Fallout

The National Highway Traffic Safety Administration (NHTSA) has launched a formal probe into Tesla's door handles, with the agency demanding extensive documentation by December 10, 2025. This follows a separate investigation into 174,000 Model Y vehicles, where door handle failures could trigger a multibillion-dollar recall. Tesla faces potential fines if it fails to cooperate, compounding its liability risks.

Legal challenges have further amplified the stakes. A lawsuit involving a fiery Model 3 crash in 2025 highlighted how bystanders were unable to open doors due to the reliance on the low-voltage battery. Another case, involving a Model Y where a child was trapped for 30 minutes in a sweltering 104°F environment, underscores the human cost of these design choices. These incidents have prompted Tesla owners to adopt extreme measures, such as purchasing emergency glass breakers and manual pull cords, to mitigate risks.

Financial and Brand Reputation Implications

The financial impact of these safety concerns is already materializing. Tesla's stock dropped 4.6% following reports of regulatory scrutiny, with analysts predicting a potential 17.9% downside in valuation if the issues persist. The company's brand reputation, long tied to innovation and cutting-edge technology, is under strain. Consumer trust has eroded as owners report switching to vehicles with traditional door handles, while critics argue Tesla has inadequately communicated the risks of its design.

Regulatory actions are also expanding beyond the U.S. China's Ministry of Industry and Information Technology is considering new safety standards requiring clearer emergency door-release mechanisms, a move that could force Tesla to retrofit its global fleet. Such requirements would add to production costs and delay deliveries, further pressuring margins.

Long-Term Valuation Risks

The convergence of safety flaws, regulatory pressure, and reputational damage poses a significant threat to Tesla's long-term valuation. While the company's redesign efforts may mitigate some risks, the delay in addressing these issues-despite early warnings-raises questions about its commitment to safety. Investors must weigh the potential costs of recalls, fines, and litigation against Tesla's broader market position.

For now, Tesla's door design flaws serve as a cautionary tale about the perils of prioritizing aesthetics over redundancy. As regulators and competitors reassess the risks of flush-mounted, electronic door handles, Tesla's ability to balance innovation with safety will be critical to preserving its valuation and brand equity.
