Tesla is being investigated after reports of seat belts disconnecting on their own

Earlier this month, the National Highway Traffic Safety Administration began investigating reports of Model Y steering wheels falling off.

• The NHTSA said it is investigating Model X SUVs from 2022 and 2023 over concerns of seat belt failure.
• The agency said it received two reports of seat belt failure.
• Earlier this month, the regulator began investigating reports of Model Y steering wheels falling off.

The National Highway Traffic Safety Administration is investigating Tesla over concerns of seat belt failure.

The safety regulator opened its investigation into Model X SUVs from 2022 and 2023 on Friday, according to a filing that was posted on the agency's website. The probe impacts about 50,000 vehicles, the agency said.

The NHTSA said it launched the investigation after it received two complaints that the SUV's front seat belt had failed to remain connected to its anchor while the owners were driving. 

"Both vehicles were delivered to the owners with insufficiently connected anchor linkages," the agency said in its report, adding that the allegations indicate the seat belt failure was because the product was "not properly connected during assembly."

Both reports said the seat belt issue occurred at low vehicle mileage and neither car was involved in an accident, according to the regulator.

Tesla did not respond to a request for comment ahead of publication.

It is one of several investigations that the NHTSA has launched into incidents involving Teslas. Earlier this month, the regulator said it was looking into reports of the steering wheel on the Model Y falling off while the vehicle was in motion. In February, Tesla issued an over-the-air recall for more than 362,000 of its cars over concerns its Full Self-Driving software may cause its cars to act "unsafe" around intersections.
