Due to issues with the operation of the back lights, Tesla had to update more than 321,000 vehicles in the US. A file with the watchdog National Highway Traffic Safety Administration makes this clear.
Rarely, a software flaw may cause the lights on one or both sides of the affected Model 3 and Model Y vehicles to randomly illuminate. This may make it harder to see in the dark.
Following driver concerns, a recall was issued. Due to the issue, there wouldn’t be any reports of accidents, injuries, or fatalities. Tesla will remotely update the software on the vehicles.
