The U.S. National Highway Traffic Safety Administration (NHTSA) opened a preliminary investigation on August 3, 2026 into roughly 1.2 million Tesla vehicles, covering Model 3 from model years 2018-2020 and Model Y from model years 2021-2023.
The probe was triggered by 156 owner complaints alleging that the front lower control arm (lower lateral link) can unexpectedly detach from the vehicle while driving.
NHTSA states such a failure severely impairs steering and directional stability, posing significant safety risks to vehicle occupants and other road users.

美国国家公路交通安全管理局（NHTSA）于2026年8月3日对约120万辆特斯拉车辆启动初步调查，涉及2018至2020年款Model 3和2021至2023年款Model Y。
此次调查源于156起车主投诉，反映车辆前下控制臂（下横向连杆）在行驶过程中可能意外脱落。
NHTSA表示，此类故障会严重削弱车辆的转向与方向稳定性，给乘员及其他道路使用者带来重大安全隐患。
