Tesla is rolling out an over-the-air software update to fix a seat belt chime issue that may result in drivers not being aware that they are not buckled in. The recall covers a total of 817,143 vehicles, comprised of 2021-2022 Tesla Model S, 2021-2022 Tesla Model X, 2017-2022 Tesla Model 3, and 2020-2022 Tesla Model Y. 

A notice filed by the National Highway Traffic Safety Administration (NHTSA) on Thursday described the nature of the seat belt chime issue. According to the NHSTA’s Safety Recall Report, a software error may prevent a warning chime from activating even if drivers do not have their seat belts on. As of January 31, 2022, Tesla is not aware of any warranty claims, field reports, crashes, injuries, or fatalities related to the condition.

The following describes the nature of the seat belt malfunction issue, as outlined in the NHTSA’s Safety Recall Report

“FMVSS 208, S7.3 (a)-(1), requires the audible seat belt reminder chime to activate upon vehicle start (i.e., driver presses the brake pedal after entering the vehicle) if the driver seat belt is not detected as buckled. On certain MY 2021-2022 Model S and Model X vehicles and on all MY Model 3 and Model Y vehicles, a software error may prevent the chime from activating upon vehicle start under certain circumstances.

“This condition is limited to circumstances where the chime was interrupted in the preceding drive cycle and the seat belt was not buckled subsequent to that interruption (e.g., the driver exited the vehicle in the preceding drive cycle while the chime was active and later returned to the vehicle, creating a new drive cycle). This condition does not affect the audible seat belt reminder chime from activating when the vehicle exceeds 22 km/h and the driver seat belt is not detected as buckled. The condition also does not affect the reliability and accuracy of the accompanying visual seat belt reminder at any point.”

The seat belt chime issue was initially brought to Tesla’s attention by the South Korea Automobile Testing & Research Institute (KATRI) on January 6, 2022. From January 10 to 22, 2022, Tesla’s vehicle software and homologation teams conducted an investigation on the condition, as well as the scope of the issue. A recall determination was made by Tesla voluntarily on January 25, 2022, though the fix would be rolled out through a free software update, similar to other patches that the company rolls out to its fleet regularly. 

It should be noted that a fix for the seat belt chime issue started rolling out in software update 2021.43.101.1, which was initially introduced to the Model 3 and Model Y on January 27, 2022. Tesla Model S and Model X vehicles who were affected by the issue started receiving the software update with the seat belt chime fix the next day, on January 28, 2022. Similar to the recalls that the company recently initiated for its vehicles, owners who are affected by the issue are not required to take any specific actions for their vehicles, except to ensure that their cars are connected to the internet.

Tesla’s remedy to the seat belt chime issue can be viewed below. 

“A firmware release will correct the software error, so that the audible seat belt reminder chime will reset if it is interrupted while chiming. Firmware release 2021.43.101.1, which includes this remedy, was introduced in Model 3 and Model Y production on January 27, 2022, and in Model S and Model X production on January 28, 2022. Separately, firmware release 2022.4.5, which also includes this remedy, will deploy over-the-air (“OTA”) to delivered vehicles in early February 2022.

“No further action is necessary from owners whose vehicles are equipped with firmware release 2021.43.101.1 or 2022.4.5 or a later release. New vehicles will not be delivered to customers without 2021.43.101.1 or 2022.4.5 or a later release. Tesla does not plan to include a statement in the Part 577 owner notification about pre-notice reimbursement to owners because there is no paid repair relating to the underlying condition and owners will receive the remedy free of charge with an OTA firmware release.”

Tesla hits FSD hackers with surprise move

In recent weeks, the company has begun remotely disabling FSD capabilities on affected vehicles, and in some instances, permanently revoking access even for owners who paid thousands of dollars for the feature.

Published

Tesla is cracking down on hackers who have figured out a way to utilize third-party programs to activate Full Self-Driving (FSD) in their vehicles — despite the suite not being approved for use in their country.

Tesla has launched a sweeping enforcement campaign against owners using third-party hardware hacks to activate FSD software in countries where the advanced driver-assistance system remains unregulated or unapproved.

In recent weeks, the company has begun remotely disabling FSD capabilities on affected vehicles, and in some instances, permanently revoking access even for owners who paid thousands of dollars for the feature.

Reports of the crackdown have surfaced across Europe, China, Japan, South Korea, and the UK, marking a significant escalation in Tesla’s efforts to enforce regional software restrictions.

FSD is Tesla’s flagship supervised autonomy package, which is available in several countries across the world. Currently limited by regulatory hurdles, it has not received full approval in most markets outside of the United States due to various things, such as safety standards, data privacy, and local traffic laws.

However, the company is working to expand its availability globally. Nevertheless, Tesla has installed the necessary hardware on vehicles globally, but locks the features based on geographic location.

Some owners have taken accessing FSD into their own hands, using jailbreak or bypass devices.

These “jailbreak” tools, typically €500 USB-style modules that plug into the vehicle’s Controller Area Network (CAN) bus, intercept signals to spoof approvals and unlock FSD, including advanced navigation, Autopark, and Summon features.

Hackers in Poland, Ukraine, and elsewhere have distributed the devices, with some claiming they work on HW3 and HW4 vehicles and can be unplugged to restore stock settings. In China alone, over 100,000 owners reportedly installed such modifications.

Tesla’s response has been swift and uncompromising. Recently, the company began sending in-car notifications and emails warning owners that unauthorized modifications violate terms of service, compromise vehicle safety systems, and expose cars to cybersecurity risks.

The email communication read:

“Your vehicle has detected an unauthorized third-party device. As a precaution, some driver assistance functions have been disabled for safety reasons. A software update will be available soon. Once you install the update, some features may be enabled again.”

Vehicles detected using the hacks have had FSD capabilities remotely disabled without refund. In some cases, owners report permanent bans, even if they had legitimately purchased the software package.

Tesla’s hardline stance underscores its commitment to regulatory compliance and safety.

Tesla has long argued that unsupervised FSD requires rigorous validation, and premature activation could endanger drivers and bystanders.

The crackdown sends a clear-cut message to those who are bypassing the FSD safeguards, but there are greater implications for Tesla if something were to go wrong. This is an understandable way to protect the company’s reputation for its FSD suite.

Tesla developing small, affordable SUV, report claims

This latest rumor deserves heavy scrutiny. Tesla has already walked away from a mass-market $25,000 EV once before.

Tesla is developing a small, affordable SUV, a new report claims, speculating that the automaker is planning to add yet another vehicle to its lineup at a price point similar to the Model 3 and Model Y, but smaller and more compact.

But it does not make a whole lot of sense, especially considering a handful of things CEO Elon Musk said and the overall plan for Tesla’s future.

Reuters reported that Tesla is in the early stages of developing an all-new, smaller, cheaper electric SUV. Citing four sources familiar with the matter, the story claims the vehicle would be shorter than the Model Y, built in China, and represent a fresh platform rather than a variant of the Model 3 or Y.

Suppliers have reportedly been contacted to discuss details, though Tesla has not commented. The move appears aimed at broadening affordability amid slowing EV demand and intensifying competition, particularly from Chinese rivals.

This latest rumor deserves heavy scrutiny. Tesla has already walked away from a mass-market $25,000 EV once before.

In 2024, the company scrapped its long-teased “Redwood” project for a budget-friendly car. Elon Musk explained the decision bluntly during an earnings call: a conventional low-cost model would be “pointless” and “completely at odds with what we believe.”

In other words, chasing a bare-bones cheap EV runs counter to Tesla’s core mission of accelerating sustainable energy through cutting-edge technology and autonomy rather than volume-driven price wars.

Musk’s own recent statements reinforce skepticism about a compact SUV pivot. Just two weeks ago, on March 25, he responded to fan requests for a minivan by posting on X: “Something way cooler than a minivan is coming.”

Elon Musk says Tesla is developing a new vehicle: ‘Way cooler than a minivan’

The remark came in the context of family-hauling needs, with Musk highlighting the Cybertruck’s ability to seat multiple child seats. It signals Tesla’s focus is shifting toward more spacious, innovative people-movers—not shrinking its lineup.

U.S. demand data echoes this logic.

The long-wheelbase Model Y L—a six-seat, stretched variant offering extra room for families—has generated massive interest wherever offered. Fans in the U.S. have basically begged for the Model Y L to make its way to the States, or for the company to develop a full-size SUV.

The Model Y L is selling well in China, where it is manufactured.

Delivery wait times for the Model Y L stretched into February 2026 as orders poured in. Tesla recently expanded the trim to eight new Asian markets, yet it remains unavailable in the United States, where consumer appetite for a larger, more practical SUV is reportedly strong.

American buyers have consistently favored bigger vehicles; the Model Y already outsells most competitors precisely because it delivers crossover utility without compromise. A compact model shorter than today’s bestseller would likely miss this mark entirely.

Tesla’s product strategy has long emphasized differentiation through autonomy, range, and desirability rather than racing to the bottom on price. Stripped-down variants of the Model 3 and Y have already struggled to ignite broad demand.

A new compact SUV built in China might sound logical on paper for cost-sensitive buyers, but it risks repeating past missteps—diluting brand cachet while ignoring clear signals from Musk and the market.

History suggests Tesla talks about affordable cars more often than it delivers them. Whether this Reuters scoop evolves into metal or joins the $25k project on the scrap heap remains to be seen.

For now, the smart money is on Tesla doubling down on “way cooler” vehicles that actually fit American families—and Tesla’s ambitious vision—rather than a smaller SUV that feels like yesterday’s news.

Tesla CEO Elon Musk says next FSD release is the one we’ve been waiting for

Tesla CEO Elon Musk teased the capabilities of a future Full Self-Driving release, but it seems like we are getting what Yogi Berra once called “Déjà vu all over again.”

On Thursday, Musk teased the capabilities and next steps for Tesla’s Full Self-Driving software, focusing squarely on the incremental improvements of the current v14.3 suite, as well as the looming arrival of v15.

He confirmed that upcoming point releases of v14.3 will deliver additional polish to the current build, smoothing out remaining edges in an already capable system. These iterative updates, Musk noted, are designed to refine performance without requiring a full version overhaul.

Tesla Full Self-Driving v14.3: First Impressions

Yet the real headline was Musk’s forecast for v15.

“V15 will far exceed human levels of safety, even in completely unsupervised and complex situations,” he wrote.

He clarified that v15 will be powered by Tesla’s long-awaited large model, an AI architecture with roughly 10x the parameters of the smaller model currently in widespread use. The leap, Musk explained, stems from the unusually rapid progress of the compact model, which has advanced so quickly that the larger counterpart has yet to catch up in real-world deployment.

However, it is becoming a pattern that is, by now, familiar to anyone following Tesla’s autonomous driving roadmap.

Musk has consistently and repeatedly framed each successive major release as the one poised to deliver game-changing autonomy. Earlier versions were similarly positioned as a movement toward the final piece of the puzzle, only for attention to pivot to the next milestone once they arrived.

The refrain has become a recurring feature of FSD communication: current software is impressive, the point releases will sharpen it further, but the true breakthrough lies one major iteration ahead.

Musk’s latest comments fit squarely into that cadence. While v14.3 point releases are expected to tighten supervised driving behaviors in the coming weeks, v15 is cast as the version that finally crosses the threshold into unsupervised operation at human-or-better safety levels across demanding scenarios.

The 10x parameter scale of the underlying large model is presented as the key technical enabler, promising richer reasoning and more robust decision-making than anything deployed to date.

Whether v15 ultimately fulfills that promise remains to be seen. Tesla’s history shows that each new target generates fresh excitement—and occasional skepticism—about timelines.

Fans realize Musk’s timelines for FSD are exciting, but rarely met:

For now, Musk’s message is familiar: the immediate focus is polishing v14.3 through targeted point releases, while the 10x-parameter large model in v15 represents the next decisive step toward fully unsupervised, superhuman safety.

Hopefully, Tesla can come through, but we can only believe that once v15 gets here, v16 will be the next big step toward autonomy.

Drivers can expect continued refinement in the short term and a significantly more ambitious leap once the large model is ready. The cycle continues, but the stakes, Musk insists, keep rising.
