NHTSA's Office of Defects Investigation (ODI) opened a preliminary evaluation on Jul 31, 2026 into roughly 1.2 million Tesla vehicles — 2018-2020 Model 3 and 2021-2023 Model Y — after receiving 156 complaints of a front suspension component detaching while driving.
The complaints center on the front lower lateral link separating from the vehicle.
The preliminary evaluation is the first stage of NHTSA's investigative process; if ODI identifies a safety-related defect, the probe can escalate to an engineering analysis, a step that often precedes a recall.

美国国家公路交通安全管理局（NHTSA）下属缺陷调查办公室（ODI）于2026年7月31日对约120万辆特斯拉车辆（2018-2020年款Model 3和2021-2023年款Model Y）启动初步评估，此前收到156起前悬挂部件在行驶中脱落的投诉。
投诉集中指向前下侧纵臂（front lower lateral link）从车辆上分离。
初步评估是NHTSA调查流程的第一阶段；若ODI认定存在安全相关缺陷，调查可升级为工程分析，这一步通常是召回的前奏。
