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.”

Tesla owners keep coming back for more
Tesla has taken home the “Overall Loyalty to Make” award from S&P Global Mobility for the fourth consecutive year, reinforcing Tesla owners’ willingness to come back. The 2025 awards are based on S&P Global Mobility’s analysis of 13.6 million new retail vehicle registrations in the U.S. from October 2024 through September 2025. The complete list of 2025 winners includes General Motors for Overall Loyalty to Manufacturer, Tesla for Overall Loyalty to Make, Chevrolet Equinox for Overall Loyalty to Model, Mini for Most Improved Make Loyalty, Subaru for Overall Loyalty to Dealer, and Tesla again for both Ethnic Market Loyalty to Make and Highest Conquest Percentage.
Tesla’s streak in this category started in 2022, and the brand has now won the Highest Conquest Percentage award for six straight years, meaning it keeps pulling buyers away from other brands at a rate no competitor has matched. Tesla’s retention among Asian households reached 63.6% and among Hispanic households 61.9%, rates that significantly outpace national averages for those groups. That breadth of appeal across demographics adds a layer of significance to a win that some might dismiss as routine.
The timing matters too. After several consecutive quarters of decline, Tesla’s share of U.S. EV sales jumped to 59% in Q4 2025. That rebound, arriving just as competitors were flooding the market with new models and incentives, suggests Tesla’s loyalty numbers are not simply the result of limited alternatives. Buyers are still choosing it when they have plenty of other options.
What keeps Tesla owners coming back has a lot to do with the and convenience of charging. The Supercharger network is the most straightforward example. With over 65,000 Superchargers globally, it remains the largest and most reliable fast-charging network in the world, and owners who have built their routines around it face a real practical cost when considering a switch. Competitors have made progress, but the consistency, speed, and availability of Tesla’s network is still the benchmark the rest of the industry is chasing. Then there is the software side. Tesla has built a model where the car you own today is functionally different from the car you bought two years ago, through over-the-air updates that add continuous game-changing improvements such as Full Self-Driving that has moved from a driver-assist feature to an increasingly capable autonomous system. For many Tesla owners, leaving the brand means starting over with a car that will not get meaningfully better over time, and that is a trade-off fewer and fewer are willing to make.

Tesla Robotaxi service in Austin achieves monumental new accomplishment
Tesla Robotaxi services in Austin have been operating since last Summer, but Tesla has admittedly been delayed in its expansion of the geofence, fleet size, and other details in a bid to prioritize safety as new technology rolls out.
But those barriers are being broken with new guardrails being removed from the program.
Tesla has achieved a significant advancement in its autonomous ride-hailing program. As of May 4, the Robotaxi fleet in Austin, Texas, has begun operating unsupervised during evening hours for the first time. This expansion moves beyond previous limitations that restricted unsupervised service to daylight hours, typically ending in mid-afternoon.

The change brings Austin in line with operations in Dallas and Houston. Those cities have supported evening unsupervised runs since their initial launches in April, and both recently received additions of new unsupervised vehicles to their fleets. This coordinated progress across Texas strengthens Tesla’s regional presence and provides a broader testing ground for the technology.
This milestone carries substantial weight in the development of autonomous vehicles. Extending operations into low-light conditions meaningfully expands the Robotaxi’s operational design domain (ODD)—the specific environments and scenarios in which the system is approved to operate safely without human intervention.
Nighttime driving presents unique technical demands: diminished visibility, headlight glare from oncoming traffic, reduced contrast for identifying pedestrians and lane markings, and greater variability in camera sensor exposure.
Tesla’s pure vision approach, powered by neural networks trained on vast real-world datasets rather than lidar or pre-mapped routes, must handle these variables reliably. Demonstrating consistent unsupervised performance after sunset validates the robustness of the end-to-end AI stack and its ability to generalize across diverse lighting conditions.
Beyond technical validation, the expansion holds important operational and economic implications. Evening hours often coincide with peak urban demand for rides, including commutes, dining, and entertainment outings.
Enabling service during these periods increases daily vehicle utilization, allowing each Robotaxi to generate more revenue while gathering additional high-value training data. Higher utilization accelerates the virtuous cycle of data collection, model improvement, and further ODD growth.
Looking ahead, this step paves the way for more ambitious rollouts. Success in low-light environments positions Tesla to pursue near-24-hour operations, potentially integrating highways and expanding into varied weather patterns. Regulators worldwide frequently demand evidence of safe performance across day-night cycles before granting wider approvals.
Proven capability in Texas could expedite deployments in planned cities such as Phoenix, Miami, Orlando, Tampa, and Las Vegas during the first half of 2026.

Moreover, scaling evening service supports Tesla’s long-term vision of a high-efficiency robotaxi network. Greater fleet productivity lowers the cost per mile, making autonomous mobility more accessible and competitive against traditional ride-hailing.
As the company iterates on software updates informed by nighttime data, reliability is expected to compound rapidly, unlocking denser urban coverage and longer-distance trips.
In summary, the introduction of an unsupervised evening Robotaxi service in Austin represents more than an incremental schedule adjustment. It signals a critical maturation of the underlying technology and sets the foundation for broader geographic and temporal expansion.
With Texas operations gaining momentum, Tesla is steadily advancing toward transforming urban transportation at scale.

Tesla Cybercab just rolled through Miami inside a glass box
Tesla paraded a Cybercab in a glass display at Miami’s F1 Grand Prix event this week.
Tesla set up an “Autonomy Pop-Up” at Lummus Park in Miami Beach from April 29 through May 3, 2026, embedded within the official F1 Miami Grand Prix Fan Fest. The centerpiece was a Cybertruck towing the Cybercab inside a glass display case marked “Future is Autonomous,” rolling through the beachfront crowd.
Miami is on Tesla’s confirmed list of cities for robotaxi expansion in the first half of 2026, making the promotion a strategic promotion that lays groundwork in a target market.
This was not Tesla’s first time using Miami as a showcase city. In December 2025, Tesla hosted “The Future of Autonomy Visualized” at its Miami Design District showroom, coinciding with Art Basel Miami Beach. That event featured the Cybercab prototype and Optimus robots interacting with attendees. The F1 pop-up this week marks Tesla’s return to Miami and follows a pattern Tesla has been running since early 2026. Just two weeks before Miami, Tesla stationed Optimus at the Tesla Boston Boylston Street showroom on April 19 and 20, directly on the final stretch of the Boston Marathon, letting tens of thousands of runners and spectators meet the robot for free, generating massive earned media at zero advertising cost.

Tesla has confirmed plans to expand its robotaxi service to seven cities in the first half of 2026, including Dallas, Houston, Phoenix, Miami, Orlando, Tampa, and Las Vegas, building on the unsupervised service already running in Austin. Musk has said he expects robotaxis to cover between a quarter and half of the United States by end of year. On the production side, Musk told shareholders that the Cybercab manufacturing process could eventually produce up to 5 million vehicles per year, targeting a cycle time of one unit every ten seconds. Scaling robotaxis to 10 million operational units over the next ten years is a key condition of his compensation package, alongside selling 20 million passenger vehicles.
As for the Cybercab’s price, Musk has said buyers will be able to purchase one for under $30,000, with an average operating cost around $0.20 per mile. Whether those numbers hold through full production remains to be seen.
