Tesla recalled nearly 6,000 U.S. vehicles because brake caliper bolts could be loose, potential causing a loss of tire pressure, Reuters reports.

The recall covers certain 2019-2021 Model 3 vehicles and 2020-2021 Model Y vehicles. Tesla’s filing with the National Highway Traffic Safety Administration (NHTSA) said it had no reports of crashes or injuries related to the issue and that the company will inspect and tighten, or replace, the caliper bolts as necessary, according to Reuters.

Tesla said that loose caliper bolts could allow the brake caliper to separate and contact the wheel rim, which could cause a loss of tire pressure in “very rare circumstances.” The company said if vehicle damage from a loose or missing fastener occurs, it would arrange for a tow to the nearest service center for repair.

The filing with NHTSA said Tesla was made aware in December of a field incident involving a 2021 Model Y vehicle with a missing fastener on the driver-side rear brake caliper.

The company has since taken measures during assembly to prevent loosening of the bolts, Reuters reports.

In related news, Tesla also issued two recalls covering nearly 8,000 vehicles with potentially faulty seat belts.

One recall covers certain 2018-2020 Model 3 sedans, along with certain 2019-2021 Model Y crossovers. That recall covers 5,530 vehicles with front seat belts that may be improperly secured to the b-pillar (the vertical section between a car’s front and rear windows).

The second covers 2,166 2019-2021 Model Ys where the second-row seat belt retractors may be improperly fastened to the car’s body. 

Both occurred due to problems fastening seat-belt components to the correct torque specification during manufacturing.
