Tesla Expected to Move to Interior Camera Detection

Tesla Expected to Move to Interior Camera Detection

Tesla will be issuing an OTA recall for the seatbelt warning system later this month, according to paperwork that was published by the National Highway Traffic Safety Administration this Friday.


This recall is estimated to impact 125,000 vehicles across Tesla’s entire model range, including the Model S, X, 3, and Y. At this time, there is no indication of this recall reaching the Cybertruck.

Relying on the Cabin Camera

The recall addresses the driver occupancy sensor – a known problem since at least 2020 on some vehicles. This recall indicates that it may impact more vehicles than just those where people have noticed an issue.

The sensor completes the circuit and provides a signal when the driver is seated – but with some vehicles, even when the sensor is depressed by the weight of the driver, no visual or audio reminders will be given when the driver’s seatbelt isn’t fastened.

Tesla hacker, Greentheonly recently discovered that Tesla is going to stop relying on the occupancy sensors in its seats, which appears related to this OTA recall.

By relying on the cabin camera, Tesla will not only be able to resolve the occupancy sensor issue, but also reduce costs across their vehicles. Tesla currently use an occupancy sensor for each seat position.

Instead Tesla is expected to use the internal camera to detect occupancy of the seats, similar to their vision-based belt tensioners. Tesla already uses the cabin camera for various tasks, such as detecting whether there are any occupants in the vehicle and for driver monitoring. In FSD 12.4, Tesla is expected to rely more heavily on its driver monitoring system in order to remove the steering wheel nag in most situations.

Advantages of Using the Cabin Camera

Leveraging the cabin camera instead of weight occupancy sensors may actually become an improvement over the sensors that can be triggered accidentally.

If a heavy object or children’s seat is placed on a seat, it can cause the seat belt warning to be triggered incorrectly.

Software Update

This will be an OTA update, which means that as usual, Tesla vehicles will not have to come into service centers. Tesla is changing how the seat belt warning reminder will function – rather than relying on the sensor, it is expected to rely on the cabin camera to trigger the visual and audio warnings if the vehicle is put into drive or reverse and the driver seatbelt isn’t fastened.

There is currently no indication whether this update will be coming to Canada or other regions besides the United States in its initial release, but eventually we expect this change to apply to all regions.
