NHTSA launches probe into Tesla suspension failures in 1.2 million Model 3 and Model Y vehicles

U.S. auto safety regulators have opened a preliminary investigation into Tesla Inc. after receiving 156 reports of suspension failures in Model 3 and Model Y vehicles that could lead to a loss of directional control. The probe, launched by the National Highway Traffic Safety Administration (NHTSA) on July 31, 2026, covers approximately 1.2 million vehicles, including Model 3 sedans from the 2018 to 2020 model years and Model Y SUVs from the 2021 to 2023 model years. Drivers reported sudden suspension failures with no advance warning, though some noted unusual noises before the incidents. No injuries or fatalities have been linked to these issues, according to NHTSA. Tesla has not yet responded to a request for comment. The investigation marks the latest regulatory scrutiny for Tesla as it faces growing legal and safety challenges.
