Tesla is cutting edge, even bleeding edge technology, but sometimes returning to the classics can help too. There is no doubt Elon Musk and likely several Tesla fans watched David Hasselhoff play Michael Knight in Knight Rider in the 1980s.
At that time, the Knight Industries Two Thousand (KITT) Pontiac Firebird Trans Am was the most advanced vehicle on the planet. The artificially intelligent car could do just about anything, drive by itself, take commands and go really, really fast. Those things all sound familiar. Lots of KITT's features are in Teslas, but there was one item that needed some work — Sentry Mode.
Tesla's Sentry Mode Improvements in 2022
Tesla continually tweaked and added more features to Sentry Mode in 2022. With the 2022 holiday update Tesla added the ability to view the vehicle's cabin camera directly from the app when Sentry Mode or Dog Mode are engaged.
In the prior update, Tesla added the ability to turn off camera-based detection, resulting in fewer Sentry Mode alerts in crowded areas. In some regions, Tesla also added the capability to adjust the length of each Sentry Mode clip.
In addition to these enhancements, Tesla now lets you use Sentry Mode and Dog Mode at the same time, as well as being able to disable Sentry Mode sounds.
Sentry Mode to Calm Down
KITT's advantage was that no one knew it was this technologically advanced car hiding a lot of tricks under the hood. KITT was super stealthy, except for the red light on the front of the shiny black front end, slowly pulsing from side to side.
Sentry Mode is a modern-day KITT, but instead of playing it cool like the Trans Am, Tesla's Sentry Mode freaks out, blinding everyone in sight. Every Tesla owner has returned to their car with a Sentry Mode notification. A lot of the time, it is some poor unsuspecting person walking to their car, and suddenly they are blinded by thousands of lumens.
Lights will Pulsate in Update 2023.2
Another Sentry Mode improvement is about to be introduced in update 2023.2. When Sentry Mode is enabled, the system will no longer blind passers-by with its bright headlights. Instead of full-on panic mode, it will now emit a gradual pulse of the headlights, ramping them up and down as a sort of warning. Hopefully, this stealthy, calm way of handling the problem will result in fewer surprised people being forced into the spotlight. It will also help when viewing Sentry Mode clips by not washing out the surroundings due to the bright flashes.
In the video below you can see the updated Sentry Mode lights when a possible threat is detected. This is currently available for the Model 3 and Model Y.
Last night, Tesla released software update 2024.45.25.15, which includes FSD V12.6.1. This update adds support for all HW3 vehicles, including the Model 3 and Model Y. We’re excited to see the continued support for HW3 owners.
FSD V12.6.1
V12.6.1 is now going wide, according to Ashok Elluswamy, Tesla’s VP of AI. This update is going to the Model 3 and Model Y for the first time - as only the Model S and Model X were included in FSD V12.6.
V12.6 is a big step forward for HW3 - it includes End-to-End on Highway, Improved City Streets Behavior, and Smoother and More Accurate Tracking - all contributing towards a better, smoother, and more comfortable build of FSD. You can read our comparison between FSD V12.6 and V13.2.2 here.
In short, FSD V12.6 performs considerably closer to V13 than V12.5.4.2 - which is a massive improvement. It performs as well as the Cybertruck version of FSD V13, which is still missing a few features when compared to other HW4 vehicles, but it’s a great sign for HW3. A lot of the improvements can be pointed to in the improvements to lane selection and decision-making - the vehicle tends to hesitate far less on V12.6, meaning the ride is a lot smoother. Many early V12.6 testers mentioned that it felt more like V13-mini than anything else.
Legacy Model S & X
We haven’t seen this update hit any legacy Model S and Model X vehicles just yet. We’re not sure whether Ashok’s statement of “generally” applies here - but it should. If you do get the update, please let us know.
Legacy Model S and Model X vehicles are still on an older FSD build and potentially won’t see another FSD update for a little while longer. While they do have the same FSD hardware as other vehicles, there are enough hardware differences that require a build specifically for these vehicles.
FSD V12.6.1 is going out now to the redesigned Model S and X with HW3 and all Model 3 and Model Y vehicles with HW3. The initial wave went out last night, and we expect to see more later today or tomorrow. If this release ends up going “wide,” we should see much larger waves go out next week.
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.
