After a month-long delay, Tesla sent FSD v12.4.2 to employees yesterday with update 2024.15.10. After just a few hours of the update going out to employees, Tesla started sending it to OG testers as well, who were already on FSD v12.4.1.
Issues Behind Delay
On X, Elon Musk broke down some of the details behind the delays. He mentioned that part of the issues behind the V12.4.2 delays were based on training. Tesla was seeing fewer interventions with FSD v12.4, but the release suffered from driving smoothness, which ironically was supposed to be one of the key features of this release.
Musk explained that part of the issue was due to too much focus on interventions, and not enough on normal driving. He compared it to training a doctor on emergency room patients, versus training on regular preventative care.
Vision-Based Attention Monitoring Changes
With FSD update 12.4.2, Tesla changed some of the language used for its Vision-Based Attention Monitoring in the release notes. Here’s a breakdown of some of the key points in the language. The changes to the release notes are below. Phrases or words that were removed are crossed out, while those added are in bold.
“When Full Self-Driving (Supervised) is enabled, the driver monitoring system now primarily relies on the cabin camera to determine driver attentiveness. This enhancement is available on vehicles equipped with a cabin camera and only when the cabin camera has clear and continuous visibility of the driver's eyes Cabin camera must have clear visibility (e.g., the camera is not occluded, eyes, arms are visible, there is sufficient cabin illumination, and the driver is looking forward at the road ahead and not wearing sunglasses, a hat with a low brimwithout sunglasses, or other objects covering thetheir eyes). Outside of theseIn other circumstances, the driver monitoring system will continue toprimarily rely on a combination of torque-based (steering wheel) and vision-based monitoring to detect driver attentiveness. When the cabin camera is actively monitoring driver attentiveness, a green dot appears next to the steering wheel icon on the touchscreen.
If the cabin camera detects inattentiveness the driver to be inattentive, a warning will appear. The warning can be dismissed by the driver immediately reverting their attention back to the road ahead. Warnings will escalate depending on the nature and frequency of detected inattentiveness, with continuous inattention leading to a Strikeout.
Cabin camera images do not leave the vehicle itself, which means the system cannot save or transmit information unless you enable data sharing.”
Arms Need to be Visible and Other Changes
There are various interesting changes here. While some of the changes are just improved wording to make the feature clearer, there are others that are worth highlighting which could point at changes to Tesla’s vision-based monitoring.
The first is the addition of “arms are visible.” Apparently, Tesla now wants to be able to see your arms to better detect attentiveness. Tesla may want to see that your arms are on the steering wheel, or they maybe they want to make sure your arms are moving so that someone isn’t able to post a static photo in front of the cabin camera to circumvent the attention monitoring. The reason isn’t clear, but looks like having your arms visible is now a requirement.
There are other small changes like the removal of a “hat with a low brim,” which was replaced by more generic wording that says the driver’s eyes must be visible.
However, near the end, Tesla removed the portion that said the driver monitoring system will rely on a combination of torque-based (steering wheel) and vision-based monitoring. This was changed to simply say that Tesla will rely primarily on torque-based (steering wheel) monitoring when vision-based monitoring is unavailable. It’s not clear whether this is just semantics and the wording now better describes how the vision-monitoring feature works, or if Tesla made changes so that the vehicle is simply either doing vision monitoring or steering wheel torque detection, and it doesn’t try to combine the two sources to detect whether the driver is paying attention.
Even more interestingly, the last line that says “cabin camera images do not leave the vehicle itself, which means the system cannot save or transmit information unless you enable data sharing,” has been removed. This could point to Tesla saving images of the cabin camera to improve its AI training model.
Either way, we’re glad to finally see FSD v12.4.2 going out to employees and early-access owners. The release is expected to have far fewer interventions and improve vehicle smoothness during braking and acceleration. If there are no major issues found, this update could go wide to all customers with FSD and on update 2024.14 or lower in the coming weeks.

Tesla has issued a recall for some vehicles due to issues linked to a revision of the Hardware 4 (HW4) computer that was introduced this past November. This recall affects all vehicles with the revised hardware except for the Cybertruck, as it uses a slightly modified version of the HW4 system.
Many vehicle owners have reported a complete failure of their Autopilot computer, which not only leaves the vehicle without FSD and Autopilot but also disables many of the active safety features that make a Tesla what it is.
Let’s take a look at this recall - because the recall is partially physical and partially a software recall.
HW4 Failure
Tesla has identified the failure and flagged it to the U.S. NHTSA (but not Transport Canada or Euro NCAP at the time of publishing) as a recall.
Tesla mentions that the vehicle’s FSD computer circuit board may short circuit, resulting in the loss of the rearview camera image. The recall itself is focused on the rearview camera - as not having a functional rearview camera breaks a Federal Motor Vehicle Safety Standard. However, it does impact more than just the rearview camera.
As previously mentioned, users have experienced the full loss of Autopilot and FSD on these vehicles, as well as reduced traction control and removal of safety features such as automatic emergency braking, collision avoidance assist, and forward collision warnings.
While the vehicle remains driveable, it is not necessarily a good idea to drive the vehicle with many of these features, especially with the reduced traction control noted by many people. We’ve already noted that while Tesla has been sending tow trucks to pick up some vehicles, it is also prompting owners to drive the vehicle to their service center in some cases.
Remedy
Unlike most of Tesla’s recalls, this one isn’t entirely an OTA recall, owing to the fact that people have already experienced circuit board shorts and are already waiting for replacements.
The software portion of the recall has already been mostly completed for any vehicles with Tesla software update 2024.45.25.3 or greater. However, a significant portion of the tracked fleet remains on update 2024.44.25.2 (approximately 20%), so we recommend updating your HW4 vehicle whenever you receive the notification.
On the hardware side, Tesla is immediately identifying and replacing hardware that has had circuit board failure. Tesla is also reaching out to customers who have expressed intermittent issues with Autopilot features, active safety features, or vehicle cameras that don't display correctly. If you have experienced any of these issues in a late 2024 vehicle, we recommend submitting a service ticket with Tesla to ensure that your vehicle isn’t affected by this recall.
After a long wait, Tesla has finally launched the refreshed Model Y - the world’s best-selling vehicle - in China. The vehicle is available for pre-order throughout the Asia-Pacific market, so let’s dive into everything new.
Currently, Tesla’s order page expects the first vehicles - the Launch Series - to begin deliveries to customers in May 2025, just about four months away. For now, there are just two variants - the Rear Wheel Drive, and the Long Range, All Wheel Drive model.
Launch Series Edition
Similar to the Foundation Series Cybertrucks, the Launch Series Model Y’s are a limited release and include a set of additional options.
You’ll get an exclusive Launch Series badge on the rear liftgate and doorsill plate. Plus, the Launch Series badging shows up in the puddle lights too. The charging console also has “LAUNCH” as a wordmark on the trim, and the interior comes with an exclusive black vegan suede finish.
Launch Series for the Long Range AWD also comes with Acceleration Boost, the first time Tesla has ever included the feature outside of an “in-app” purchase.
What’s New
There are a lot of new things in the 2025 Model Y, from a new and sharp-looking exterior, an improved interior, and even better specs to round off the whole package. There are even several surprises that we didn’t know about. There’s a lot to like here.
Exterior
Tesla has redesigned the front and rear of the vehicle with iconic new light bars, which they mention increase vehicle aerodynamics, efficiency, and range. Part of this includes redesigned body castings for the Model Y refresh, reducing parts from 70… to just one. That’s fewer gaps, all designed to make an even quieter ride than before. We’re excited to see how all these improvements perform - after all, increasing stiffness is the key to a better ride.
The front bumper camera is also visible - so that’ll be the first for a Tesla vehicle outside of the Cybertruck. Hopefully, they’ll include it in FSD and Actually Smart Summon as well, but right now, at least on the Cybertruck, it’s only used for Autopark or, of course, to use it manually.

Indirect Rear Light Bar
The rear light bar is actually not aimed away from the car - but at it. According to Tesla, it's the first indirect reflective body panel taillight - and it looks cool. Tesla has also redesigned several curves on the car - it looks far more aerodynamic and cuts a sharp figure over the original Model Y. These changes will improve range and performance.

Tesla has also introduced a new color - Glacier Blue - exclusive to the 2025 Model Y Refresh for now. The standard color option is Stealth Grey, while Pearl White Multicoat, Glacier Blue, Quicksilver, and Ultra Red are all available as options.

Tesla has also removed the hitch option from the Model Y Refresh. This is a big change - it was the only non-premium level Tesla vehicle to include a tow hitch. We’re hoping that Tesla does include a tow hitch in versions coming to North America and Europe - as many users do use them. If it is indeed gone, that’ll mean the only vehicles left in the lineup with tow hitches will be the Cybertruck, Model S, and Model X.
Interior
First up - ventilated seats and ambient lighting will be the first two things you see, along with new soft-touch finishes across the interior. Tesla has really hit the mark with the interior of the Model Y Refresh - it looks clean and sharp.
Updated interior with ambient lighting
Not a Tesla App
The updated interior still features a 15.4-inch touchscreen - the same size as previous models but also includes an 8” rear touchscreen for all versions of the vehicle, similar to the refreshed Model 3.
Tesla has added improved connectivity to the vehicle - improving the range for the Phone Key, clearer calls, and faster cellular and Wi-Fi connectivity. This is likely a chipset improvement for the infotainment module - and includes a newer version of Bluetooth, as well as support for 5G. We’ll dig into these details once we know more.
The updated speakers are cleverly hidden away inside the trims, and we expect a lot of improvements for Tesla’s already fantastic audio - especially in the Long Range AWD version.
One of the coolest features is power reclining seats - you’ll be able to recline or raise your rear seats at the touch of a button in the rear of the vehicle and potentially in the vehicle menu, too. That’s going to be an amazing convenience feature for families and those moving luggage around.
Turn Signal Stalk
Not a Tesla App
In a surprising move, Tesla says they have listened to customer feedback and added a precision-engineered turn signal stalk. There’s only a single stalk on the left side of the steering wheel while the gear shifter remains on the screen and Autopilot remains as a steering wheel button.
The steering wheel buttons are similar to the Cybertruck, which provide “clicky” feedback. Since the turn signals have moved over to a stalk, Tesla is introducing customizable steering wheel buttons. You’ll likely be able to set them to features like turning on the front or rear cameras, voice commands or other features.
Handling
Just like the Model 3 refresh, Tesla has worked some magic on the suspension, improving vehicle handling and comfort while also offering more responsive steering and an even quieter ride. This includes updated tires, wheels, and a new suspension.
New Wheels, New Suspension
Not a Tesla App
No word yet on Adaptive Suspension - that’ll likely be a hold-out for the Performance variant, which will show up later in 2025.

*Range for the Model Y Refresh is WLTP, while for the 2024 vehicle, it is EPA estimates. WLTP estimates are generally on the higher side owing to geography and temperature in the Asia-Pacific.
There’s a lot to take in right here, spec-wise. The Model Y Refresh AWD is faster than its predecessor and has a considerably longer range. According to Tesla’s spec sheet, it also charges slightly faster - even faster than the current LR RWD with its LFP battery. That’s a great improvement across the board.
Beautiful Curves
Not a Tesla App
The RWD is less of an immediate improvement - but this is a Standard Range RWD - not a Long Range RWD, so the comparison isn’t exactly comparable to the 2024 LR RWD. It seems likely that Tesla will replace the Long Range RWD with the 2025 Standard Range RWD once it arrives in North America and Europe. However, even the RWD has a pretty hefty improvement in the 0-60 section.
When Does It Arrive
Tesla says that it’ll be shipping the Model Y Refresh in just a few short months - customer deliveries of the Launch Series should begin deliveries in May - if you’re in the Asia-Pacific region. For customers in Europe and North America, we’ll probably have to wait a few months before the 2025 Refresh arrives here - likely in the early summer months.
Tesla won’t keep people waiting too long - after all, it's the much-awaited refresh of the world’s best-selling vehicle. We’re super excited to see more of it and hopefully get our hands on it for a test drive in the future.
