The National Highway Traffic Safety Administration (NHTSA) has launched an investigation into Tesla’s electric door handle systems, specifically targeting 2021 Model Y vehicles, amid growing concerns over potential safety risks. The investigation stems from reports of door malfunctions following low-voltage battery failures, which could leave vehicle occupants unable to enter or exit the vehicle.
The federal safety regulator aims to evaluate Tesla’s door lock power supply methodology and overall reliability. This scrutiny is particularly significant as all Tesla vehicles sold in the United States utilize electrically powered door mechanisms.
Since 2018, more than 140 complaints have been documented regarding Tesla doors becoming stuck or malfunctioning. The NHTSA has
acknowledged nine specific “failure reports,” with seven aligning with previously documented incidents. Of particular concern are situations involving trapped children, with some owners reporting having to break vehicle windows to rescue occupants during emergencies.
Safety advocacy groups have raised concerns about the accessibility of Tesla’s manual release mechanisms during emergency situations. Michael Brooks from the Center for Auto Safety emphasized that merely including manual release instructions in the owner’s manual is insufficient, particularly for passengers or ride-share customers who wouldn’t have time to consult documentation during an emergency.
Rosemary Shahan, president of Consumers for Auto Reliability and Safety, expressed strong criticism of the situation, stating that vehicle owners shouldn’t need to resort to breaking windows to access their vehicles when door handles malfunction, especially in cases involving trapped children or pets.
When questioned about these safety concerns, Tesla Board Chair Robyn Denholm offered a brief response, stating only that the board takes safety incidents seriously. Tesla has not provided any official comment regarding the investigation.
The safety concerns extend beyond U.S. borders, with both Chinese and European regulators increasing their scrutiny of electric and flush door handle designs. These regulatory bodies have expressed concerns about how such designs might complicate rescue operations during emergencies.
The NHTSA has committed to ongoing monitoring of entrapment reports involving interior door operation and has indicated it will take additional action as necessary. The agency emphasized particular concern about entrapment scenarios in emergency situations, especially involving children in high-temperature conditions.
This investigation adds to a growing list of regulatory examinations facing Tesla, including ongoing reviews of its Autopilot and Full Self-Driving features’ safety. The timing of this investigation is notable, as there have been minimal updates on existing probes into Musk’s company since President Trump’s administration.
The issue highlights a broader conversation about the safety implications of modern vehicle design features, particularly in electric vehicles where traditional mechanical systems are
increasingly replaced by electronic alternatives. The investigation underscores the critical balance between innovative design and practical safety considerations, especially in emergency situations where rapid exit from the vehicle might be necessary.
The NHTSA’s investigation will focus particularly on the reliability of power supplies to the door locks and the overall approach Tesla uses to ensure door functionality. This examination could have significant implications for future vehicle design standards and safety regulations in the electric vehicle industry.
