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.
The recall documents posted by the National Highway Traffic
Safety Administration say the problem happens only if the driver left the
vehicle in the previous drive cycle while the chime was sounding.
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.
The problem was discovered by South Korea's Automobile
Testing and Research Institute on Jan. 6. Tesla investigated and determined
that a recall was needed on January 25, the documents say.
The chime still sounds if the vehicles go over 22 kilometres
per hour and the driver's belt isn't buckled.
The US recall is the largest in the Austin, Texas, company's
history and comes as the company faces increasing scrutiny from NHTSA, the
nation's road safety agency.
The agency this week said that Tesla would recall nearly
54,000 cars and SUVs because their “Full Self-Driving” software lets them roll
through stop signs without coming to a complete halt.
Recall documents posted Tuesday say that Tesla will disable
the feature with a software update. The “rolling stop” feature allows vehicles
to go through intersections with all-way stop signs at up to 5.6 miles (9 kilometres)
per hour. The feature would work as long as the owner chose to activate it and
the car didn't detect any “relevant” moving cars, pedestrians, or bicyclists.
Tesla's “Full Self-Driving” software is being tested by
selected owners on public roads. It cannot drive itself, and the company warns
that drivers must be ready to intervene at any time.
NHTSA also is looking into a driver's complaint that “Full
Self-Driving” software caused a crash in California.
It's also investigating why Tesla cars using the company's
less-sophisticated “Autopilot” driver-assist system have repeatedly crashed
into emergency vehicles parked on roadways.
The newest recall covers all four models in its lineup.

vehicles in the US since 2013. -AP
