马斯克又摊上事了，特斯拉因Model 3车门缺陷面临新调查

Core Viewpoint - The U.S. National Highway Traffic Safety Administration (NHTSA) has initiated a defect investigation into the Tesla Model 3 due to concerns over the mechanical door unlocking mechanism, which may be difficult to operate and identify in emergencies [1][2] Group 1: Investigation Details - The investigation involves over 179,000 units of the 2022 Tesla Model 3 [1] - The inquiry was prompted by a defect complaint alleging that the mechanical door unlocking mechanism is poorly designed and lacks clear identification, making it hard to locate in emergencies [1] - Tesla vehicles primarily rely on an electronic locking system, which opens doors via buttons instead of traditional mechanical handles [1] Group 2: Safety Concerns - Experts have long criticized the visibility, clarity, and ease of operation of mechanical unlocking devices, particularly for rear passengers [1] - A recent lawsuit against Tesla was filed following a severe accident involving a Model S in Wisconsin, where five passengers died because they could not open the car doors due to design flaws [1] Group 3: Regulatory Context - The acceptance of a defect complaint by the regulatory agency does not equate to a recall order but marks the first step in the regulatory review process [2] - If safety-related defects are confirmed, further actions may be taken [2] - This investigation is part of a broader scrutiny of Tesla's door mechanisms, as NHTSA previously investigated door lock issues in the 2021 Model Y, which also prevented some passengers from exiting the vehicle [2] Group 4: Company Response - Tesla's Chief Designer, Franz von Holzhausen, indicated that the company is redesigning the door handles [2] - Tesla has launched a new safety page on its website, stating that door handles will automatically unlock in the event of a collision [2]
