Tesla Update Disables 12V Outlet in Sentry Mode, Limits Usage
Tesla’s recent 2024.32.3 software update has changed the functionality of the 12V power outlets in the Model Y, impacting owners who rely on these outlets for accessories like coolers (this one is our choice that fits perfectly in the Model Y sub-trunk).
Previously, the 12V outlets in the trunk and center console remained active when the car was parked with Sentry Mode, Dog Mode, or climate control on. However, with the new update, these outlets now only function when a driver is in the seat or when Camp Mode is enabled.
Tesla’s updated manual explains that power is only available when the vehicle detects a user in the driver’s seat or when there’s interaction with the touchscreen. This change means that many accessories placed in the trunk, such as coolers, will no longer stay powered when Sentry Mode is active and the car is unoccupied. Bummer.
The manual further advises against using non-Tesla accessories in the 12V outlets, as they may interfere with the vehicle’s electronics. Tesla recommends unplugging any third-party accessories if users notice malfunctions or unexpected behaviors like indicator lights or overheating.
For owners accustomed to keeping items like food and beverages cool while parked during the summer, this change may present a new challenge in managing power to their accessories.
Tesla North readers recently noticed this change and we can confirm this is the case, as we realized our cooler hasn’t stayed on after coming back to a parked car that had Sentry on. Let’s hope Tesla will change this back in a future update, as having a cold cooler was super helpful on summer road trips and tailgate parties.
Interestingly enough, this same software update for the 2024 Model 3 does not limit usage to having a driver in the seat or touchscreen use. For the Model 3, Tesla says power is available when the car is considered “awake”, meaning when features such as Summon, Cabin Overheat Protection, Keep Climate On, Dog Mode, Camp Mode, Sentry Mode, etc. are enabled.
Tesla says the Model 3 is also awake whenever the low voltage battery is being charged or is in use, during high voltage charging, when the vehicle is communicating with the mobile app, etc. Tesla also points out that leaving an accessory plugged in does not deplete the low voltage battery.
For the 2021+ Model S and Model X, Tesla says it also requires a driver in the seat or touchscreen use for these sockets to be powered on.
