Tesla's flush door handle design is facing scrutiny from regulators in Europe and the U.S. following reports of failures during power outages. The Dutch RDW and the U.S. National Highway Traffic Safety Administration (NHTSA) have initiated formal reviews to assess the safety implications of these incidents, which could potentially trap occupants inside vehicles and hinder emergency access. In response, China has proposed mandatory mechanical door releases for passenger cars to ensure operability during power loss. Tesla is reportedly working on design improvements to address these concerns.
