In Tesla software update 2024.32 and onwards, Tesla has made a big—and unexpected—change to how its vehicles handle power sockets. This change impacts every vehicle except the Cybertruck, where you can already adjust how power sockets are handled on a case-by-case basis.
Power Socket Change
This change to the power sockets means that in 2024.32, Tesla vehicles will have their 12v sockets and USB ports turned off while in Sentry Mode. Previously, while the car was awake or Sentry Mode was active, the 12v sockets in the rear of the vehicle and any of the USB ports would all remain powered.
Now, owners will no longer be able to operate devices that rely on these ports once the vehicle falls asleep. This change renders some accessories almost useless, such as vehicle fridges. Owners previously relied on Sentry Mode coming on when their vehicle was parked, which kept the fridge in the vehicle’s sub-trunk powered. This change will also prevent owners from using Sentry Mode to keep USB ports powered to charge laptops and other devices.
Until further changes are made, owners will have to use Camp Mode to keep 12v sockets and USB ports powered. However, Camp Mode leaves the vehicle unlocked, making it insecure and unsuitable for things like sub-trunk fridges.
Cybertruck Power Interface
Tesla may be planning to integrate the Outlets & Accessories menu from the Cybertruck into the rest of its vehicles. The outlets menu in the Cybertruck allows you to keep the cabin (and bed) outlets in the vehicle active, even when the vehicle isn’t in use. These outlets remain powered for up to 12 hours after the Cybertruck is exited.
Sentry Mode Improvements
Drew Baglino, Tesla’s now former SVP of powertrains and energy, said back in February of this year that Tesla was looking at reducing the amount of power that Sentry Mode used. He stated that Sentry Mode power consumption needs to be improved and that the team was working on an update to reduce power by about 40%. According to Baglino, the improvements were expected to come in the second quarter of this year, but it’s not clear if this change in update 2024.32 is part of those changes that will lower Sentry Mode’s power consumption.
Even if these are planned changes, we hope Tesla makes them optional, and lets owners choose when to keep outlets powered and when to conserve energy.
Tesla Service Responds
Update: Tesla service has now responded to some users regarding this issue. A Tesla service rep says that Tesla is receiving a lot of feedback regarding this change, meaning that this isn’t simply a bug. However, it’s still not clear whether this change was made to improve power consumption while Sentry Mode is enabled, whether it’s to reduce wear on the low-voltage battery which powers the 12v power sockets and USB ports, or if i’s due to an entirely different reason.
Hopefully, we’ll hear something officially from Tesla soon.
