US closes 2022 probe into 695,000 Tesla vehicles over unexpected braking

The US National Highway Traffic Safety Administration (NHTSA) on Thursday said it ​had closed its 2022 preliminary evaluation ‌into 695,000 Tesla vehicles over unexpected deceleration, citing low demonstrated hazard to drivers and a ​substantial drop in incidents.

Here are a ​few details:

The investigation covered Model 3 and ⁠Model Y vehicles.

NHTSA said that Tesla ​had released software updates in early ​2022 to target unexpected deceleration.

Incident reports declined to 45 in 2024, 19 in 2025, and ​three since the start of 2026, ​according to the auto safety regulator. There were ‌300 ⁠such reports when the investigation was opened.

The regulator said the reported conditions did not alter the vehicle’s lateral positioning ​in their ​lanes and ⁠did not cause significant loss in distance between the subject ​and following vehicle to lead ​to ⁠a collision.

Last week, NHTSA had separately closed an expanded probe covering an estimated 376,241 ⁠Model ​3 and Model Y ​vehicles over loss of steering control.
