Tesla’s door handles may spur new US safety rules

U.S. regulators are weighing new safety standards for electronically operated door handles after a series of incidents involving Tesla’s “falcon wing” and “bioweapon” doors. The proposed rulemaking would target any vehicle equipped with power‑opened doors that could unintentionally open while the car is in motion, a scenario that has raised concerns among safety officials and consumer advocates.

Recent incidents prompting action

In the past year, at least three high‑profile cases have been reported where Tesla owners experienced doors opening unexpectedly while driving. In one instance, a Model X’s rear door swung open on a highway, forcing the driver to brake sharply and narrowly avoiding a collision. Similar reports have emerged from owners of the Model Y and the upcoming Cybertruck, which also feature power‑operated latch mechanisms.

The National Highway Traffic Safety Administration (NHTSA) has opened preliminary investigations into these events, citing “potential hazards to vehicle occupants and other road users.” The agency’s preliminary findings suggest that a combination of software glitches and mechanical wear could cause the latch to disengage under certain conditions.

What the proposed rule could entail

If adopted, the rule would likely require manufacturers to implement redundant safety checks that verify a door is fully latched before the vehicle can be driven. Additional requirements may include:

• A fail‑safe mechanism that automatically re‑locks the door if an opening is detected while the vehicle is moving.
• Enhanced diagnostic alerts that inform drivers of latch malfunctions via the instrument cluster.
• Periodic durability testing of power‑door components under varied temperature and vibration conditions.

The rule could also mandate that manufacturers provide clear, standardized warnings in owner manuals and on‑screen prompts, ensuring drivers understand the proper operation and maintenance of electronic door systems.

Impact on the auto industry

While Tesla’s door designs have been a focal point, the regulation would apply to any automaker offering power‑opened doors, including luxury brands and emerging electric‑vehicle startups. Industry analysts predict that compliance costs could be significant, especially for smaller manufacturers that lack extensive testing infrastructure.

However, proponents argue that the rule would level the playing field by establishing a baseline safety standard, potentially reducing the risk of costly recalls and liability claims down the line.

“Safety should never be an afterthought, especially as vehicles become more software‑driven,” said an NHTSA spokesperson during a recent briefing.

The rulemaking process is expected to take several months, with a public comment period slated to begin later this summer. Stakeholders, including automakers, consumer groups, and safety experts, will have the opportunity to submit feedback before the final regulations are drafted.
