Tesla rolls out new trailer alarm feature in latest Cybertruck software update [2024.8.4]

Tesla has released its latest software update for the Cybertruck, and it includes a brand new towing that will hopefully migrate to the Model X and Model Y as well.

The new feature is included in version 2024.8.4, which started rolling out to Cybertruck owners on Monday. It doesn’t really have a name, with the release notes calling it ‘Vehicle Alarm Includes Trailer.’ As the title implies Tesla has extended the monitoring of the vehicle’s alarm to include the trailer hitch.

What this means is that if your trailer is plugged into the hitch, and someone tries to steal it by unplugging it, the vehicle’s alarm will activate. This feature appears to be turned on by default, according to the release notes.

This feature is so far only available on the Cybertruck, but considering the Model Y and the Model X can both tow, we expect it to be released to those vehicles as well in the near future.

This new trailer alarm feature isn’t the only trailer-friendly feature we are expecting Tesla to release. Last week Drive Tesla reported that the in-vehicle user interface (UI) will soon display trailer-friendly Superchargers stalls, which will make road-tripping with a trailer much easier.

The 2024.8.4 software update also includes several other features. One was included in a previous update, ‘One-Time Charge Limit’, and others that have already been released in other Tesla vehicles, like being able to use Bluetooth headphones with the rear screen and keep track of tire mileage.

Cybertruck owners can now also use Auto Wipers. Interestingly the release notes for this feature mention “Autopilot features,” even though Autopilot isn’t yet available on the Cybertruck.

Here are the full 2024.8.4 release notes.
