FSD update v12.5.6.2 is expected to start rolling out this week. FSD 12.5.6.2 will be the successor to v12.5.6.1, which has been rolling out over the past week. This latest release is still limited to AI4 vehicles, but is expected to expand to HW3 vehicles in the coming days or weeks.
There’s one bug fix that’s coming in v12.5.6.2 that’s worth the wait. Tesla is finally making changes to the dreaded “Full Self Driving may be degraded; Poor weather detected” notification that plagues the ears of everyone driving with FSD in anything less than California sunshine.
The Complaint
The old FSD weather degradation notification would pop up constantly in poor weather, and ding at nearly full volume. And in light rain, it would sometimes come up, then go away, then come up again. More infuriating was the fact that because it was a critical (red exclamation) notification, whatever audio you were listening to would duck down in volume behind the incessant dinging.
Of course, turning on Joe Mode would lower the volume of the ping, but didn’t fix the audio ducking. We wonder if this could finally be the Joe Mode update with a volume slider that owners have been asking for since 2020.
The Solution
Ashok Elluswamy, Tesla’s now VP of AI, confirmed on X that v12.5.6.2 would be releasing this coming week, along with a fix to the constant dinging and notifications. This will be a nice change, and we’re excited to see what else Tesla has been cooking up while we wait for FSD v13, which should be just a few short weeks away.
Given that FSD v12.5.6.1 has going been going out in small waves this past week, we’ll likely see v12.5.6.2 roll out initially to early access testers, and if it goes well, out wide to the rest of the AI4 owners in short order. Within a week or two, HW3 owners will hopefully also get the update, once Tesla finishes the optimizations required to get the new model running smoothly on HW3.

Tesla has drastically improved the connectivity portion of their app in the last year or two. Prior to these updates, if you want to start the vehicle’s climate system, you needed to open the Tesla app, wait for the vehicle to wake up, then press the HVAC icon.
Tesla then introduced “delayed” commands, which allows you to press the HVAC icon upon opening the app, and Tesla would then automatically send the command to the vehicle once it’s awake.
More recently, Tesla made it so the vehicle sends its most recent data to Tesla before falling sleeping, meaning that when someone opens the Tesla app, they’re looking at the most recent vehicle data, even if the vehicle is sleeping.
Now Tesla is introducing offline commands for newer models, letting users send a command to their vehicle over Bluetooth instead of relying on an Internet connection. The process is transparent to users, if the user is in close proximity to their vehicle, the app will send the command over Bluetooth, otherwise it will send it over WiFi or cellular.
Offline commands are faster and more reliable. When you press the button to open the frunk, it’ll now do this instantly, instead of waking up the vehicle first. However, it looks like not every model will be supported.
Legacy Model S / Model X
Legacy Model S and Model X vehicles - so any S/X produced before the 2021 refresh, won’t be able to use offline commands, at least at this time. A user reached out to Tesla Service to find out why their offline commands weren’t working, and a tier two Tesla service rep confirmed that this feature isn’t supported on legacy vehicles.
Legacy vehicles will continue to require internet connectivity for commands, except for unlocking the vehicle.
Legacy Model S and X unfortunately don’t receive the majority of features in recent updates due to various reasons. One of them is likely due to the smaller userbase and another is likely due to the vertical screen orientation that differs from the newer models.
This limitation for offline commands is likely due to a technical limitation preventing Tesla from implementing it on these vehicles, rather than any lack of trying.
Requirements
To use offline commands with the Tesla app, you’ll need to run version 4.38 or higher of the Tesla app. The most recent version is 4.38.5, which is available for Android and iPhones. Your vehicle will also need to be running update 2024.38 or higher, which is currently only available to about a third of the Tesla fleet.
You’ll also need to have one of the supported models, which appear to be the Model 3/Y, 2021+ Model S/X and the Cybertruck.
Future Support?
Tesla has committed to supporting legacy vehicles where possible, with other improvements for safety like improved Forward Collision Warning and Automatic Emergency Braking for MCU1 vehicles and FSD 12.3.6. It is possible that eventually, these vehicles may receive support for offline commands, but it won’t be likely, given Tesla’s priorities to get features working on the newer vehicles.
Tesla is updating the Model 3 and Model Y Rear-Wheel Drive variants with new battery packs. This new pack will replace the current BYD Blade pack in these vehicles. Its interesting to see Tesla making battery pack changes to vehicles, especially in light of recent news on Tesla working with its cell manufacturing partners and internally to make better batteries.
The new pack, which is likely replacing the current BYD 7C pack in the Model 3 and Model Y RWD variants, is going to be called the CATL 6M. The last time we had a CATL LFP pack in the RWD variants was back in 2021.
This pack will be bringing a 6% increase in overall capacity, from 60.1 kWh to 62.5 kWh. At about a 4% increase in energy, it’s not a huge jump, but the pack is also expected to bring improved charging performance due to a higher nominal capacity and voltage. Another benefit will be its reduced mass, with the new battery pack being about 44 pounds (20 kg) lighter. These items all contribute to range and charging performance, so we could potentially see a range increase in these RWD models.
However, Tesla previously software locked the extra 2.5 kWh to match the BYD packs that were being shipped at the same time as the CATL packs - which mostly just resulted in slightly improved charging performance and better battery longevity.
Pack Chemistry
This pack is an LFP - or Lithium Iron Phosphate. LFP packs have more stable chemistry, resulting in less degradation, but less energy density for weight. They also perform poorly in contrast to their NMC siblings in extreme cold or extreme heat. However, they can be charged to 100% all the time, and Tesla actually recommends this. We wrote about Tesla’s battery tech in detail, for those looking for more information.
There is a possibility that manganese will be introduced into this new pack. Manganese improves energy density, and also helps with low-temperature performance, which would help to mitigate some of the concerns with today’s current LFP packs in places that see cold weather on the regular, like Canada or the Nordic nations.
Release Date? North America?
This battery back likely won’t come to North America now, due to tariffs against Chinese batteries and cells. Customers in Europe, Asia, and other markets can expect to see these batteries in their vehicles sometime next year while Tesla works on other solutions to provide the North American market with a cost-competitive LFP pack that’s sourced from materials within the continent.
