Tesla is recalling more than 817,000 vehicles in the U.S. because the seat belt reminder chimes may not sound when the vehicles are started and the driver hasn't buckled up.
The recall covers the 2021 and 2022 Model S sedan and Model X SUV, as well as the 2017 through 2022 Model 3 sedan and 2020 through 2022 Model Y SUV, according to documents posted Thursday by safety regulators.
Federal motor vehicle safety laws require the chimes to sound when vehicles are started, and the sound stops when front belts are buckled.
Tesla will fix the problem by sending out an over-the-air software update early this month. The safety agency says without the chime, a driver may not know their seat belt is unbuckled, increasing the risk of injury during a crash.
The company says in the documents that it's not aware of any crashes or injuries due to the problem. A visual seat belt reminder is still displayed.
