Tesla reviews 53,822 vehicles with "full autonomous driving" 1:15
Washington (CNN Business) --
Tesla issued its second recall in just a week, this time for an alert that doesn't always go off if the driver's seat belt is unbuckled.
The faulty seat belt alert affects 817,143 vehicles, including 2021 and 2022 S, X, 3 and Y models.

Tesla has already begun rolling out a software update to fix the issue on production vehicles, according to a document filed with the National Highway Traffic Safety Administration (NHTSA).
Other Tesla vehicles will receive an over-the-air software update early this month.
Tesla's recalls over the past week are not a burden to vehicle owners or the company.
Drivers do not need to schedule a service appointment.
Both are fixed by software updates, which reduces the severity and cost of recalls.
(Earlier this week, Tesla pulled its "full self-driving" software, which had been programmed to run stop signs.)
Federal safety regulations require a seat belt reminder to sound after starting a vehicle if the driver's seat belt is detected as not fastened.
This seatbelt beep was not activating on some Teslas due to a software bug, according to the automaker's filing.

The fault occurred after a driver got out of the vehicle when the doorbell rang and re-entered it.
The problem does not occur if the vehicle exceeds 20 kilometers per hour, according to Tesla.
The automaker's visual alert for an unfastened seat belt was also unaffected by the bug, according to the document.
The South Korea Automobile Research and Testing Institute notified Tesla of the problem on January 6 this year.
Tesla concluded on January 25 that there was indeed a problem.
As of January 31, there had been no crashes, injuries or deaths as a result of the ruling, according to the document Tesla provided.
The automaker did not respond to a CNN Business request for comment.

Tesla has received increased scrutiny from the NHTSA in the past year.
The administration said yesterday that it is considering an investigation into complaints that Tesla vehicles sometimes brake unnecessarily.
Last year, NHTSA scrutiny led Tesla to disable a way to play video games when its vehicles are in motion.
It also launched an investigation into Teslas colliding with emergency vehicles while using Autopilot or other assisted driving features.
