Thousands of Tesla cars recalled for loose brake bolt

Nearly 6,000 Tesla cars are being recalled due to loose brake bolts that could lower tire pressure and lead to a crash.

The National Highway Traffic Safety Administration issued a recall last week for certain Model 3 (2019-2021) and Model Y (2020-2021) cars. The safety agency estimates only 1 percent of the potentially affected cars actually have the defect.

In 2020, Tesla delivered 442,511 Model 3 and Y cars.

The problem was discovered in December 2020 in a 2021 Model Y with a missing fastener on the driver-side rear brake. Tesla said no crashes or injuries have been reported because of the bolt issue.

In the recall notice, Tesla said drivers should be able to hear an unusual noise if the bolt unfastens completely and starts hitting the wheel rim.
