Tesla is rolling out an over-the-air software update that would allow the company to address a windshield defrosting issue present in vehicles that are equipped with a heat pump. A total of 26,681 vehicles are affected by the issue, according to the National Highway Traffic Safety Administration’s (NHTSA) Safety Recall Report. 

Vehicles that are part of the “recall” include 2021-2022 Tesla Model S, 2020-2022 Tesla Model Y, 2021-2022 Tesla Model 3, and 2021-2022 Tesla Model X. The US regulator noted in its Safety Recall Report that a software error in the affected vehicles may cause a valve at the cars’ heat pumps to open unintentionally, resulting in refrigerant being trapped inside the evaporator. This could adversely affect a vehicle’s defrosting performance. 

 

While the issue is quite notable, Tesla notes that it is not aware of any crashes, injuries, or fatalities related to the affected vehicles’ heat pump issue. 

A chronology of the heat pump issue was outlined in the NHTSA’s Safety Recall Report. As per the document, Tesla began rolling out firmware release 2021.44 and subsequent releases through firmware release 2021.44.30.6 to affected vehicles on or about December 10, 2021. Later that month, the company started receiving complaints from customers about the loss of heating performance in extreme weather conditions.

An investigation to find the root cause of the issue was commenced then. By January 11, 2022, it was determined that the lack of software command to close the Electronic Expansion Valve (EXV) after communication interruptions in firmware release 2021.44 through 2021.44.30.6 was a potential cause of the problem. Software update 2021.44.30.7 and later releases, which reintroduced a software command to close the EXV, was rolled out on January 15, 2022, as a precautionary measure.

Following discussions with the NHTSA’s Office of Vehicle Safety Compliance and Transport Canada about consumer complaints, Tesla conducted tests to assess the compliance of new vehicles delivered with the software command found in firmware release 2021.44 through 2021.44.30.6. Unfortunately, the results of these tests revealed that new vehicles delivered with firmware release 2021.44 through 2021.44.30.6 may still present issues in worst-case scenarios.

After confirming the root cause of the issue, a recall determination was made for the affected vehicles on January 26, 2022, the final day of the compliance tests. The affected vehicle population for the recall was then expanded out of an abundance of caution on February 7, 2022, to incorporate vehicles that are currently running firmware release 2021.44 through 2021.44.30.6, but are yet to install firmware release 2021.44.30.7 or later.

The remedy for the issue was outlined in the NHTSA’s Safety Recall Notice. As per the document, the fix for the issue would be rolled out through firmware release 2021.44.30.7. The update, similar to Tesla’s other key patches for its vehicles, would be released over-the-air and completely free of charge. 

“Firmware release 2021.44.30.7 and later releases remedy the condition by reintroducing a software command to close the EXV, thereby preventing refrigerant from entering the evaporator. No further action is necessary from owners whose vehicles are equipped with firmware release 2021.44.30.7 or a later release. 

“Tesla does not plan to include a statement in the Part 577 owner notification about reimbursement for pre-notice repairs to owners since all of the affected vehicles remain covered under the new vehicle warranty, and owners will receive the remedy free of charge with an OTA firmware release.”

Tesla and xAI announced their groundbreaking joint project, Digital Optimus, also nicknamed “Macrohard” in a humorous jab at Microsoft, earlier this week.

This software-based AI agent is designed to automate complex office workflows by observing and replicating human interactions with computers. As the first major outcome of Tesla’s $2 billion investment in xAI, it represents a powerful fusion of hardware efficiency and advanced reasoning.

Tesla’s specialized AI acts as “System 1”—the fast, instinctive executor—processing the past five seconds of real-time computer screen video along with keyboard and mouse actions to perform immediate tasks.

xAI’s Grok model serves as “System 2,” the strategic “master conductor” or navigator, providing high-level reasoning, world understanding, and directional oversight, much like an advanced turn-by-turn navigation system.

When combined, the two can create a powerful AI-based assistant that can complete everything from accounting work to HR tasks.

Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI

The system runs primarily on Tesla’s low-cost AI4 inference chip, minimizing expensive Nvidia resources from xAI for competitive, real-time performance.

Elon Musk described it as “the only real-time smart AI system” capable, in principle, of emulating the functions of entire companies, handling everything from accounting and HR to repetitive digital operations.

Timelines point to swift deployment. Announced just days ago, Musk expects Digital Optimus to be ready for user experience within about six months, targeting rollout around September 2026.

It will integrate into all AI4-equipped Tesla vehicles, enabling parked cars to handle office work during downtime. Millions of dedicated units are also planned for deployment at Supercharger stations, tapping into roughly 7 gigawatts of available power.

Digital Optimus directly supports Tesla’s broader autonomy strategy. It leverages the same end-to-end neural networks, computer vision, and real-time decision-making tech that power Full Self-Driving (FSD) software and the physical Optimus humanoid robot.

By repurposing idle vehicle compute and extending AI4 hardware beyond driving, the project scales Tesla’s autonomy ecosystem from roads to digital workspaces.

As a virtual counterpart to physical Optimus, it divides labor: software agents manage screen-based tasks while humanoid robots tackle physical ones, accelerating Tesla’s vision of general-purpose AI for productivity, Robotaxi fleets, and beyond.

In essence, Digital Optimus bridges Tesla’s vehicle and robotics autonomy with enterprise-scale AI, promising massive efficiency gains. No other company currently matches its real-time capabilities on such accessible hardware.

It really could be one of the most crucial developments Tesla and xAI begin to integrate, as it could revolutionize how people work and travel.

Tesla is adding an awesome new driving feature to Model Y vehicles, effective on Juniper-updated models considered model year 2026 or newer.

Tesla is rolling out a new “Comfort Braking” feature with Software Update 2026.8. The feature is exclusive to the new Model Y, and is currently unavailable for any other vehicle in the Tesla lineup.

Tesla writes in the release notes for the feature:

“Your Tesla now provides a smoother feel as you come to a complete stop during routine braking.”

Interestingly, we’re not too sure what catalyzed Tesla to try to improve braking smoothness, because it hasn’t seemed overly abrupt or rough from my perspective. Although the brake pedal in my Model Y is rarely used due to Regenerative Braking, it seems Tesla wanted to try to make the ride comfort even smoother for owners.

There is always room for improvement, though, and it seems that there is a way to make braking smoother for passengers while the vehicle is coming to a stop.

This is far from the first time Tesla has attempted to improve its ride comfort through Over-the-Air updates, as it has rolled out updates to improve regenerative braking performance, handling while using Full Self-Driving, improvements to Steer-by-Wire to Cybertruck, and even recent releases that have combatted Active Road Noise.

Tesla set to activate long-awaited Cybertruck feature

Tesla holds a unique ability to change the functionality of its vehicles through software updates, which have come in handy for many things, including remedying certain recalls and shipping new features to the Full Self-Driving suite.

Tesla seems to have the most seamless OTA processes, as many automakers have the ability to ship improvements through a simple software update.

We’re really excited to test the update, so when we get an opportunity to try out Comfort Braking when it makes it to our Model Y.

Tesla is finally bringing an update of its Robotaxi platform that Android users will love — mostly because it seems like they will finally be able to use the ride-hailing platform that the company has had active since last June.

Based on a decompile of software version 26.2.0 of the Robotaxi app, Tesla looks to be ready to roll out access to Android users.

According to the breakdown, performed by Tesla App Updates, the company is preparing to roll out an Android version of the app as it is developing several features for that operating system.

The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android:

“Strings like notification_channel_robotaxid_trip_name and android_native_alicorn_eta_text show exactly how Tesla plans to replicate the iOS Live Activities experience. Instead of standard push alerts, Android users are getting a persistent, dynamically updating notification channel.”

This is a big step forward for several reasons. From a face-value perspective, Tesla is finally ready to offer Robotaxi to Android users.

The company has routinely prioritized Apple releases because there is a higher concentration of iPhone users in its ownership base. Additionally, the development process for Apple is simply less laborious.

Secondly, the Robotaxi rollout has been a typical example of “slowly then all at once.”

Tesla initially released Robotaxi access to a handful of media members and influencers. Eventually, it was expanded to more users, so that anyone using an iOS device could download the app and hail a semi-autonomous ride in Austin or the Bay Area.

Opening up the user base to Android users may show that Tesla is preparing to allow even more users to utilize its Robotaxi platform, and although it seems to be a few months away from only offering fully autonomous rides to anyone with app access, the expansion of the user base to an entirely different user base definitely seems like its a step in the right direction.
