Tesla is recalling more than 321,000 vehicles over a software issue that causes the tail lights on some cars not to work properly. The automaker announced the action on Saturday in a National Highway Traffic and Safety Administration filing (PDF) spotted by Reuters. The recall covers 2023 Model 3 and 2020 to 2023 Model Y vehicles manufactured for US customers.

“In rare instances, taillamps on one or both sides of affected vehicles may intermittently illuminate due to a firmware anomaly that may cause false fault detections during the vehicle wake up process,” the NHTSA notice states. “Brake lamps, backup lamps and turn signal lamps are not affected by this condition and continue to operate as designed.”

Tesla will release a software update to address the issue. The company hasn’t had reports of any crashes or injuries related to the bug. The automaker became aware of the problem in late October. In a separate announcement the day before, Tesla recalled about 30,000 due to an issue that can cause the front passenger airbag in Model X vehicles to deploy incorrectly in some situations.

As of this year, Tesla has so far issued 19 recalls in the US. Earlier this month, the company recalled 40,186 Model S and Model X vehicles over a software issue that could cut power steering assistance to vehicles going over potholes. Before that, the company recalled more than a million vehicles over windows that weren't working properly.
