美国汽车召回讨论把完成修复的车辆数列为重点

美国国家公路交通安全管理局在召回机制峰会上讨论如何提高车辆修复率。该机构表示，2025年经其监管的召回接近900起，涉及超过2900万辆汽车，仍有数以百万计的车辆存在尚未处理的安全召回。即使维修免费，车主也可能需要请假、寻找替代交通或安排孩子照看。约四成车主把不便列为未完成维修的主要原因。

对于可由软件处理的问题，远程更新可以省去前往服务点的步骤。局长乔纳森·莫里森表示，该机构对远程和线下召回采用相同监管方式，正在探讨通知方式是否可以更灵活。讨论关注的结果是车辆是否真的修复，以及如何确认已完成修复，不只是寄出多少通知。目前披露的是监管方的研究方向，涉及更换零部件的召回仍需相应的硬件处理。监管方还在讨论，若车辆已接受无线修复，后续采用哪种通知方式更合适。目前这部分仍处于探索阶段。
