Tesla is officially recalling 125,227 vehicles in the United States, as per a recent announcement by the US National Highway Traffic Safety Administration. The cited reason for this mass recall is a seat belt warning system malfunction, which could potentially increase the risk of injuries in collisions.

The regulator said the vehicles failed to comply with the federal safety requirements as their seat belt warning light and audible chime may not be activated when the driver is unbelted.

The recall affects certain 2012-2024 Model S, 2015-2024 Model X, 2017-2023 Model 3 and 2020-2023 Model Y vehicles. Tesla will release an over-the-air software update to fix the issue, with deployment expected to start in June.

The remedy will remove dependency on the driver seat occupancy sensor from the software and only rely on the driver seat belt buckle and ignition status to activate the seat belt reminder signals, the NHTSA said.

Tesla recalled 200,000 Model S, X, and Y vehicles in the U.S. in January due to a software malfunction which could obstruct drivers' visibility while reversing. It also recalled 3,878 Cybertrucks in April to fix an accelerator pedal pad that could come loose and get lodged in the interior trim.

U.S. auto safety regulators also opened an investigation last month into whether Tesla's recall of more than 2 million vehicles announced in December to install new Autopilot safeguards was adequate following a series of crashes.
