Following a recall issued earlier this week for nearly 54,000 electric cars and SUVs because they could fail to come to a complete stop at a stop sign when using the Full-Self Driving feature, electric vehicle maker Tesla (TSLA) is now recalling over 817,000 vehicles over a seatbelt safety issue.

The recall affects Tesla’s 2017 to 2022 Model 3, 2021 to 2022 Model S, 2021 to 2022 Model X, and 2020 to 2022 Model Y vehicles.

According to the recall notice, the audible chime may not activate when electric vehicles start and the driver does not have their seatbelt buckled. This could prevent the driver from realizing that they do not have their seatbelt buckled, which could increase the risk of injury during a crash.

It is also a violation of a Federal Motor Vehicle Safety Standard, the recall notice said.

To repair the issue, Tesla will perform an over-the-air software update at no charge to affected vehicle owners.

Owners are expected to be notified by mail of the recall on April 1. Questions about the recall can be directed to Tesla customer service at 1-877-798-3752.

The seatbelt recall comes just days after Tesla issued a recall for its Full-Self Driving feature’s “rolling stop” issue.

The recall affects the automaker’s 2017 to 2022 Model 3, 2016 to 2022 Model S, 2016 to 2022 Model X, and 2020 to 2022 Model Y vehicles.

Tesla is remedying the problem by issuing an over-the-air software update to owners that will disable the “rolling stop” functionality for free.

Affected vehicle owners will be notified of the recall by mail on March 28.

As of Thursday at 12:55 p.m. ET, shares of Tesla were trading at $909.50, up $3.84, or 0.42%.
