Tesla to release over-the-air software update to fix seat belt chime malfunction on 817k cars
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.”

SpaceX files confidentially for IPO that will rewrite the record books
SpaceX files confidentially for a record-breaking IPO targeting a $1.75T valuation and $80B raise, driven by Starlink growth and its xAI merger.
Elon Musk’s rocket and satellite company submitted its draft registration to the U.S. Securities and Exchange Commission today for an initial public offering, targeting June at a $1.75 trillion valuation. This would be the largest in history.
SpaceX has filed confidentially with the SEC, first reported by Bloomberg. SpaceX would be valued above every S&P 500 company except Nvidia, Apple, Alphabet, Microsoft, and Amazon.
The filing uses a confidential process that allows companies to work through SEC disclosures privately before initiating a public roadshow. With a June target, official details through a formal prospectus is expected to go public in April or early May, after which SpaceX must wait at least 15 days before beginning investor marketing.
While SpaceX is best known for its Falcon 9 and Starship rockets, the $1.75 trillion valuation is anchored by Starlink, its satellite internet service. Starlink ended 2025 with 9.2 million subscribers and over $10 billion in revenue, which is a figure analysts project could reach a staggering $24 billion by the end of 2026. A February all-stock merger with xAI, Musk’s artificial intelligence venture, further boosted the valuation.

Bank of America, Goldman Sachs, JPMorgan Chase, and Morgan Stanley are lined up as senior underwriters. SpaceX is also considering a dual-class share structure to preserve insider voting control, and plans to allocate up to 30% of shares to retail investors, which is roughly three times the typical norm.

Elon Musk hints at “official ceremony” with throwback photo to close Tesla Model S, Model X chapter
Elon Musk promises an official ceremony to mark the end of Tesla Model S and Model X production.
Tesla has officially begun winding down production of the Model S and Model X, sending farewell emails to U.S. customers on March 27 and updating the website to reflect the end of the line. Shoppers visiting Tesla.com now find only a limited set of Model S and Model X inventory units available for purchase, with no option to configure a new factory build. The move formalizes what CEO Elon Musk announced on the company’s Q4 2025 earnings call in January, when he said it was “time to basically bring the Model S and X programs to an end with an honorable discharge.”
Musk posted on X a throwback photo of himself speaking at the Model S production launch in 2012, and noting “We will have an official ceremony to mark the ending of an era. I love those cars.”
The mention of an official ceremony is notable. Tesla has not held a formal farewell event for a vehicle before, and Musk’s wording suggests this will be something deliberate rather than a quiet line shutdown. Given that Musk’s X post shows a photo of him on stage with a microphone in front of an audience at the Fremont factory, it wouldn’t be too far-fetched to expect a closing ceremony to take place at the same location. Perhaps? Whether it becomes a public event, a private gathering for employees, or a livestreamed moment on X remains to be seen.
Custom orders of the Tesla Model S & X have come to an end. All that’s left are some in inventory.

The Model S first went on sale nearly fifteen years ago and was Tesla’s first fully in-house designed vehicle, proving that an electric car could be fast, desirable, and capable of long distance on a single charge. The Model X followed in 2015, turning heads with its unmistakable and distinctive falcon-wing doors, while becoming one of the first all-electric SUVs on the market. Tesla’s two flagship vehicles would ultimately push legacy automakers to take all-electric transportation seriously and help fund development of the more affordable Model 3 and Model Y.
By 2025, however, both models had been reduced to a rounding error in Tesla’s sales figures. Musk was direct about what comes next, stating “We are going to convert that production space to an Optimus factory. It’s part of our overall shift to an autonomous future.”

That shift is already underway. Tesla officially started Optimus Gen 3 production at its Fremont factory in January 2026, with the line targeting a run rate of one million units per year. The Gen 3 robot features 22 degrees of freedom per hand, runs on Tesla’s AI5 chip, and shares the same neural network architecture as Full Self-Driving. A dedicated Optimus factory at Gigafactory Texas is also under construction, with a planned annual capacity of 10 million units. The production lines that once built the Model S and Model X are being converted to support that ramp.
Tesla confirmed it will continue to support existing owners with service, software updates, and parts for as long as people own the vehicles. For buyers still interested in a new example, remaining U.S. inventory is discounted and the window is closing fast.

Elon Musk announces disappointing Tesla Optimus update
In a post on X on March 31, Musk stated that Optimus 3 is mobile but requires some finishing touches before it is ready to be shown to the world. This update comes on the final day of the first quarter, a period when Tesla had previously signaled expectations for a Gen 3 reveal.
Elon Musk announced a disappointing update to the unveiling of Tesla Optimus and its third-generation iteration, missing a timeline it aimed to hit in the first quarter of the year.
Musk has confirmed that the highly anticipated Optimus Gen 3 humanoid robot is already walking around and operational, yet the public unveiling will face a short delay as the company applies final refinements.

The announcement follows reports of Optimus Gen 3 appearing at the Tesla Diner in Los Angeles, where it was observed serving and moving about until sunset. Images and videos shared by observers captured the robot in action, highlighting its progress in real-world mobility.
Tesla had aimed to showcase the production intent version of Optimus Gen 3 during the first quarter of 2026, positioning it as a major step toward factory deployment and eventual commercial availability. Musk has described the robot as featuring advanced capabilities, including highly dexterous hands with significant degrees of freedom, powered by Tesla’s AI systems for complex tasks.
This minor postponement aligns with Tesla’s iterative approach to development. Earlier statements from Musk indicated that Gen 3 would represent the most advanced humanoid robot yet, designed primarily for internal factory use before scaling to external customers.

Production timelines point toward low-volume output starting in the summer of 2026, with volume ramp-up targeted for 2027. The delay underscores the company’s commitment to quality over speed, ensuring the robot meets rigorous standards for safety and performance in practical environments.
Optimus represents a cornerstone of Tesla’s long-term vision beyond electric vehicles. Musk has repeatedly emphasized that successful humanoid robotics could transform industries by addressing labor shortages and enabling new forms of productivity.
Competitors in the space continue to advance their own platforms, yet Tesla’s vertical integration, from custom actuators to end-to-end AI training, positions Optimus as a potential leader. Community reactions on social media range from excitement over visible progress to impatience with shifting timelines, a familiar pattern in Tesla’s innovation journey.
Investors and enthusiasts view Optimus as critical to Tesla’s valuation, potentially surpassing its automotive business in scale. With the robot already demonstrating walking and basic interactions, the finishing touches likely involve software polishing, hardware fine-tuning, and reliability enhancements.
Musk’s update suggests the reveal could arrive in the coming weeks or months, maintaining momentum toward broader deployment.
As Tesla pushes the boundaries of physical artificial intelligence, this latest development keeps Optimus in the spotlight. The company continues to prioritize rapid iteration while delivering on its promises to shareholders and customers. The robotics revolution at Tesla appears closer than ever, promising profound impacts on manufacturing, services, and daily life in the years ahead.
