The Tesla ownership experience is intended to be as convenient as possible, with the vehicles themselves needing very little maintenance and practices like charging being effortless with the Supercharger Network’s plug-and-play nature. Yet even amidst all these conveniences, Tesla owners have cited a notable pain point in their ownership experience: their cars’ 12V battery.

Similar to traditional vehicles, Teslas utilize a conventional 12V battery to power components like emergency blinkers, airbags, seatbelt pre-tensioners, and the infotainment system. Typical 12V batteries last about 3-4 years under normal use in a fossil fuel-powered vehicle, but among Tesla owners, especially those who drive frequently, the lifespan of 12V batteries have been reported to go down to as short as 1-2 years.

Adding to the inconvenience is the fact that Teslas currently do not have a feature that notifies owners about the health of their cars’ 12V batteries. Tesla owners have responded to this by requesting for an update that would allow them to view the current state of their vehicles’ 12V batteries. One such request was posted on Twitter recently, with Tesla enthusiast @TeslaVibes stating that such a feature needs to be implemented in a future update.

Interestingly enough, Elon Musk completely agreed with the Tesla enthusiast’s request. The Tesla CEO added that major software improvements are set to be released for vehicles’ 12V batteries, which should allow them to last longer. “Couldn’t agree more — major software improvements are already in place to extend its life & more coming,” Musk wrote.

Considering Musk’s post, it seems that an update that would include 12V battery health warnings is all but confirmed. Such a feature will likely be universally appreciated by Tesla owners, as it could address a particularly infuriating part of the electric car ownership experience. Such a feature, if any, would definitely reduce the instances of owners running into major inconveniences when their vehicles’ 12V battery dies.

Elon Musk’s Twitter post suggests that Tesla is well aware of the limitations that 12V batteries still bring to the EV ownership experience. With this in mind, it would not be surprising if the company comes up with a superior alternative for 12V batteries in the coming years. Tesla, after all, is known for its quick pace of innovation, and the 12V battery is certainly an area that is in great need of some innovation.

It should be noted that the earliest versions of the original Tesla Roadster did not use a traditional 12V battery. Instead, Tesla opted to utilize a portion of the vehicle’s main lithium-ion battery pack to supply 12V for the all-electric sports car’s accessories and lights. The system was quite novel, but the idea was later dropped in favor of a more traditional 12V battery. Conventional 12V batteries were initially used for the original Roadster 2.0, and in every vehicle that Tesla has released since.

Tesla officially begins sunset of Model S and Model X

In the latest move to show Tesla is planning to eliminate the Model S and Model X from production, the company’s Korean arm has officially set a firm cutoff date of March 31, 2026, for new orders of both models.

Tesla has officially started its process of sunsetting the Model S and Model X just months after the company confirmed it would stop producing the two flagship vehicles in 2026.

This step marks the end of an era for the vehicles that helped establish not only Tesla’s prowess as an automaker but also its status as a disruptor in the entire car industry. While these two cars have done a tremendous amount for Tesla, the signal that it is time to wind down their production has evidently arrived.

In the latest move to show Tesla is planning to eliminate the Model S and Model X from production, the company’s Korean arm has officially set a firm cutoff date of March 31, 2026, for new orders of both models.

This is the first time Tesla has announced a hard global deadline for the Model S and X, as after that date, only existing inventory will be available in South Korea.

The move to bring closure to the Model S and Model X aligns with CEO Elon Musk’s plans for Tesla moving forward. During the Q4 2025 Earnings Call in January, Musk said the two cars deserved an “honorable discharge” for what they have done for the company.

The long-running programs are primarily being removed so that manufacturing lines can be repurposed for high-volume manufacturing of the Optimus humanoid robot. Tesla is targeting a production rate of up to one million units each year.

The Model S and Model X being removed from Tesla’s plans is a tough choice, but it was one that was written on the wall. Sales of these premium models have declined sharply in recent years, and even with Plaid configurations that are performance-forward, the company still has had trouble getting them sold.

In 2025, the Model S and Model X together accounted for roughly 3 percent of Tesla’s global deliveries, down significantly from prior periods as competition intensified in the luxury EV segment and buyers shifted toward more affordable options like the Model 3 and Model Y.

The Model S saw sales drop over 50 percent year-over-year in some quarters, while the Model X faced similar pressures from rivals, including the Rivian R1S and BMW iX.

Despite their dwindling volume, the Model S and Model X remain technological showcases. The Plaid variants deliver blistering acceleration, advanced Full Self-Driving capability, and luxurious interiors.

The phase-out paves the way for Tesla’s strategic pivot toward autonomy, robotics, and higher-volume vehicles.

Tesla brings closure to flagship ‘sentimental’ models, Musk confirms

Fremont will continue producing the refreshed Model 3 and Model Y, ensuring the factory remains a key automotive hub while expanding into robotics. Tesla has stated that the shift is not expected to result in job losses and could increase headcount as Optimus production ramps up.

For Tesla fans, the sunset represents a bittersweet moment. The Model S, introduced in 2012, proved EVs could compete with luxury sedans, while the Falcon-wing-door Model X set new standards for family haulers. Owners can expect continued software support and service for years to come.

Many fans have pushed for the Model X to hang around due to its appeal for families.

With the two cars heading out, Tesla’s priority now becomes its future products, especially that of the Optimus robot, which is the main reason for the S/X platform’s conclusion.

Tesla shows off mysterious vehicle at Giga Texas

The mysterious structure, partially unboxed amid construction materials, has sparked widespread speculation among Tesla enthusiasts and analysts. Many are convinced it is the long-rumored Model Y L, the extended-wheelbase variant already popular in China, now arriving in Texas for potential U.S. production.

Tesla seemingly showed off a mysterious vehicle at Giga Texas, one that seems to be completely different than anything the company currently makes for the U.S. market.

The vehicle, which was spotted on the plant’s property, appears to be similar to the Model Y L that has not yet launched in North America, and is currently built at Gigafactory Shanghai in China.

Drone pilot Joe Tegtmeyer captured intriguing footage at Tesla’s Giga Texas on March 23, 2026, revealing what appears to be a large, blue plastic-wrapped vehicle body resting inside a wooden shipping crate outdoors.

The mysterious structure, partially unboxed amid construction materials, has sparked widespread speculation among Tesla enthusiasts and analysts. Many are convinced it is the long-rumored Model Y L, the extended-wheelbase variant already popular in China, now arriving in Texas for potential U.S. production.

The images show an elongated silhouette that stands out from standard Model Y bodies. Side-by-side comparisons shared in replies to Tegtmeyer’s post highlight key differences: the rear door extends farther over the wheel arch than on a regular Model Y, and the rear glass appears to run all the way to the spoiler lip without the metal trim seen on shorter versions.

One overlay analysis noted that the visible proportions align precisely with the Chinese-market Model Y L, which measures approximately 4.98 meters long with a 3.04-meter wheelbase, which is about seven inches longer overall than the standard Model Y sold in the U.S.

The vehicle is a bare “body-in-white” shell, typical of prototypes sent abroad for tooling validation and local manufacturing ramp-up. Tesla has already launched the six- and seven-seat Model Y L in China and other markets, where it offers roughly 10% more cargo space and greater family-friendly versatility.

This sighting fits Tesla’s broader strategy. Industry observers expect the company to localize Model Y L production at Giga Texas by mid-2026 to serve American families seeking extra room without stepping up to the larger Cybertruck or a future full-size SUV.

Bringing the design stateside could add tens of thousands of annual deliveries while leveraging existing Model Y lines. People have been adamant that they want the Model Y L in the U.S., especially as Tesla plans to fade the Model X, the company’s most ideal vehicle for large families, out of production in the near future.

Tesla Model Y lineup expansion signals an uncomfortable reality for consumers

While Tesla has made no official comment, the timing, amid Giga Texas expansion and steady Model Y output, suggests the mysterious crate is more than a random prototype.

If confirmed as the Model Y L, it marks another step in Tesla’s effort to refresh its bestselling SUV for global demand. The vehicle would perform exceptionally well in the U.S., and despite the company’s rather mute stance on bringing it to America, this might be the biggest hint to date that it could be on the way.

Tesla Cybertruck just won a rare and elusive crash safety honor

Only the most outstanding of performances in crash tests can warrant an IIHS Top Safety Pick+ award, as vehicles listed with that ranking must achieve “Good” ratings in the small overlap front, updated side, and updated moderate overlap front tests, along with “Acceptable” or “Good” headlights standard on all trims.

Tesla Cybertruck landed a rare and elusive safety honor from the Insurance Institute for Highway Safety (IIHS). It was the only pickup truck in the U.S. market to do so.

The IIHS rewarded the Cybertruck with the Top Safety Pick+ honors, the highest marks a vehicle can receive from the agency.

Only the most outstanding of performances in crash tests can warrant an IIHS Top Safety Pick+ award, as vehicles listed with that ranking must achieve “Good” ratings in the small overlap front, updated side, and updated moderate overlap front tests, along with “Acceptable” or “Good” headlights standard on all trims.

Cybertruck was the only truck to also win an NHTSA Five-Star Safety rating, making it the only pickup available on the market to be recognized with top marks from both agencies.

There are a multitude of options for pickups in the U.S. market, as it is one of the most popular vehicle types for consumers in the country. Pickups are great vehicles for anyone who does any sort of hauling or is just looking for extra space for any variety of reasons.

Pickups are also inherently safer than other body types on the road, mostly because they are larger and heavier, making them more favorable against other vehicle types in the event of a collision. However, Tesla has a significant advantage in safety with its vehicles because it engineers them to not only be safer in collisions, but also easier to repair.

The Cybertruck managed to achieve “Good” ratings, the highest marks available by the IIHS, in all three Crashworthiness categories, as well as “Good” ratings in both Crash Avoidance and Mitigation assessments.

It also received “Good” ratings across all driver and pedestrian crash-test performance metrics, except for one, where it earned an “Acceptable” rating for rear passengers in the Chest category.

The Cybertruck’s outstanding crash test performance has won it this incredible mark as the pickup still tends to be one of the more polarizing vehicle designs on the market.

It is no secret that Tesla has struggled with demand of the Cybertruck due to pricing, but the recent rollout of a trim that was temporarily priced at just $59,990 showed plenty of people want the all-electric pickup.
