NHTSA Opens Preliminary Investigation Into Tesla Suspension Failures Affecting 1.2 Million Vehicles
The National Highway Traffic Safety Administration (NHTSA) has opened a preliminary investigation into roughly 1.2 million Tesla vehicles over reports of a suspension defect that may lead to a loss of vehicle directional control.
According to a filing from the NHTSA's Office of Defects Investigation, the investigation covers 2018–2020 Model 3 and 2021–2023 Model Y vehicles. The agency has received 156 complaints regarding the issue, which involves the detachment of the front lower lateral link—a critical component of the vehicle's suspension system.
In most reported cases, the failure occurred without advance warning. However, some complaints noted unusual noises prior to the detachment. The defect raises safety concerns because a sudden loss of suspension integrity could impair the driver's ability to steer and control the vehicle, particularly at higher speeds or during maneuvers.
A preliminary investigation does not automatically mean a recall will follow, but it is a necessary step toward determining whether a safety defect exists and whether corrective action is warranted. The NHTSA will likely gather additional data from Tesla and may request parts for further analysis before deciding on next steps.
