Several months ago, Tesla infamously started turning off power to its 12V sockets in its vehicles when someone wasn’t in the vehicle. This affected all vehicles, including the ever-popular Model Y. The reason provided for the removal was inappropriate modification of vehicles to use high-power devices, which could potentially cause dangerous situations.
This left many accessories, such as vehicle fridges, inoperable since they relied on power staying with Sentry Mode.
In its current state, your vehicle disables the rear 12V cigarette lighter-style sockets inside the center console and USB ports, when no one is detected inside the vehicle. The only current workaround to keeping these outlets with power is to use Camp Mode, but this has disadvantages such as the climate system staying on and walk-away locks being turned off.
This change also impacted USB power provided over any of the vehicle’s USB ports. This made it difficult for users to run sub-trunk fridges or other accessories that would continuously draw power, as Camp Mode consumes quite a bit of energy to maintain the vehicle’s internal temperature.
Update: Both the Model Y and Model X include a 12V socket in the rear left pillar of the vehicle, which is located under a flap, alongside a 12V socket in the front of the vehicle. The Model S and Model 3 only include USB ports and a 12V socket in the front.
The Cybertruck is Tesla’s only vehicle with 110V sockets at this time.
New Accessory Power Feature
Now, in a surprise move, Tesla is restoring access to the 12V sockets when the vehicle is powered off if users enable a new option called “Accessory Power.”
Tesla states that power is available whenever the vehicle detects a user is available or when the Keep Accessory Power On is enabled.
Turning on this new option will enable power across the entire vehicle, including the 12V socket, 12V (max 16A) rear plug (if equipped), and the vehicle’s USB ports. This will let users charge devices or use vehicle accessories, even when they’re not in the vehicle.
This is actually an improvement over the original way to keep these plugs powered without a user present, which required leaving Sentry Mode enabled, which uses a significant portion of energy itself.
The new Accessory Power option will be able to be turned on in your vehicle under Controls > Charging > Keep Accessory Power On.
Limitations
Similar to Sentry Mode and other features, accessory power is only enabled while the option is on and the vehicle’s battery remains above 20%, at which point, it’ll be turned off.
Tesla also warns that keeping the new accessory option on will cause the vehicle to consume additional energy, even if devices are not plugged into any of the outlets, so this should be an option that should be used selectively, when needed.
Release Date
It looks like this feature was supposed to make it out in the 2025.8 update, but to our knowledge, it hasn’t been enabled in any vehicles yet. Our best guess is that it’ll be enabled in a future 2025.8 update, or in the upcoming Spring Update, which will likely add other exciting features — at least if it’s anything like Tesla’s 2024 Spring Update.
We reported back in October that Tesla was looking for alternatives to keep accessories powered on without users present, so we’re super happy to hear this news, as it really shows that Tesla listens to its customers. It’s exciting to see Tesla restore a feature that had a lot of user support behind it, and we’re sure users will be thrilled to be able to use their fridges and accessories again.
If you’re a major user of accessory power, tell us what your primary use case is. Is it charging a laptop while you’re away from your vehicle, or is it running a sub-trunk fridge during your road trips?
We’d love to see some additional input on how Tesla can continue to improve this feature, so let us know in our forums or social media.

Tesla’s Vice President of Vehicle Engineering, Lars Moravy, recently took to X and opened the floor for user input. There, he asked the community for features and improvements they’d like to see to make Teslas better heading into 2026.
This post generated thousands of suggestions - and we recapped the best of them. There were also a few that Lars responded to, giving owners hope for some much-requested future changes, so let’s take a look at what may be coming
Lumbar Profile Support
Today, lumbar support is one of the few items that is not saved in the Tesla profile. That means if you have multiple drivers who use the same vehicle, you’re often left adjusting this setting manually, as it retains the setting that was last used. One community member suggested saving your lumbar setting to your profile just like Tesla does for other seat settings.
Lars said making this change seems doable, but it’ll take some engineering magic. The lumbar support isn’t tied to an absolute sensor like the other seat settings. This suggests that Tesla does not have an exact value to save, as it does with other seat functions, but Lars believes Tesla can find a way to save lumbar preferences. Tesla could potentially time how long the motor runs to get to the user’s lumbar setting and save this value.
With that said, it seems the vehicle engineering team may take a look at this one, and we may see it included in a future update.
Model 3 Signal Stalk Retrofit
The move away from traditional stalks in favor of the steering wheel buttons on the Refreshed Model 3 has been a point of debate. While the author is squarely in the camp of steering wheel buttons (at least with the Cybertruck), many dissent and say that the buttons on the Refreshed 3 aren’t as satisfying or easy to use.
Many other drivers also prefer the tactile feel and muscle memory of a physical stalk for signaling. Tesla appears to favor stalks, as they retained the turn signal stalk with the new Model Y. There are also rumors that Tesla is going to reintroduce the turn signal stalk to the Model 3.
If Tesla adds stalks back to the new Model 3, current 2024+ Model 3 owners are still left without stalks. However, a user suggested adding stalks as a retrofit option. Lars said that he would try to consider a retrofitted signal stalk for the Refreshed Model 3, similar to the simplified version in the Refreshed Model Y.
While less definitive than the lumbar support response, it appears that Tesla may at least consider offering a stalk retrofit for the new Model 3. If you’re a lover of signal stalks and can’t wait for Tesla to get an official one - we recommend the Enhauto S3XY Stalks, which are customizable and feel very close to Tesla’s original fit and finish.
With that said, it’s nice to see Tesla incorporating more community feedback into its vehicle design these days. Perhaps one day, they’ll address the infamous auto wipers. They have gotten better, but they’re still not as reliable as what’s available in most other vehicles. With that said, we look forward to the changes that will emerge from these recent conversations.
Sometimes, even with Tesla’s intensive bug-testing regime, bugs manage to make it out into the wild. In this particular case, a European user (@darkwaffle48484 on X) noticed that their 2024 Model 3 was using up more battery than normal while parked. Normally, they noted that the vehicle would lose about 1-2% per week; however, recently, they noticed much larger drops of 3-4% per night.
They monitored their Tesla widget and noticed the car wasn’t entering deep sleep. The widget consistently showed a recent connection time—usually within the past 45 minutes.
Fix Inbound
After discussing the issue with other Tesla owners and realizing it was somewhat widespread, they contacted Tesla Service. The service team confirmed that it was a firmware bug affecting the Telematics Control Unit (TCU), which prevented the vehicle from entering deep sleep mode.
The TCU is essentially the communications hub of your Tesla - and is mounted on the ceiling of newer vehicles such as the Model 3 and the new Model Y. It enables cellular and location services (via GPS) and also handles Wi-Fi and Bluetooth services. Tesla Service stated that this bug is planned to be fixed in update 2025.14.6, although the exact version number could change. However, they confirmed that they are aware of the issue and it is being addressed.
@darkwaffle48484
When the user reached out to Tesla Service, Tesla Service responded with the following (translated from Dutch):
“It has been confirmed that this is a firmware bug. The fix is in one of the next updates. Currently, it is planned for 2025.14.6 (subject to change). Do you have any more questions?”
Potentially Region-Specific
This bug could potentially be region-specific. TCUs often require specific hardware components, such as modems, as well as specific firmware versions that support different regions and cellular providers. These enable Tesla to comply with local cellular standards and regulations and ensure that your vehicle can connect to the networks available in that particular region.
At this point, it’s not clear when the fix will roll out, but given that update 2025.14.1 has practically stopped rolling out, Tesla may be waiting to resume the rollout with update 2025.14.3 or this 2025.14.6 version.
If you’ve noticed this issue and are in a non-European nation, let us know.
