In a number of Tesla Model 3 vehicles ranging from 2020 to 2023, as well as on the 2023 Model Y, the rear lights may “intermittently illuminate” due to an issue that can cause “false fault detections during the vehicle wake-up process.” This issue is affecting over 321,000 cars, and according to the NHTSA, it can “increase the risk of collisions” in dark conditions, since the taillights are not functioning properly as a result of it.
Fortunately, like most Tesla recalls, this is something that can be fixed with an over-the-air software update. Despite the fact that most of these are issues that can be fixed with firmware updates and don’t need you to service your whole car to fix them, recalls still need to be issued over them unlike with our smartphones. After all, these are issues that, if they go unfixed, can put yourself, and other drivers, in danger.
In the case of this update, it is currently rolling out to affected units. Cars in production or pre-delivery containment after November 6th, 2022 also have this issue fixed.
