Tesla is reportedly looking to strike a deal with Sigma Lithium Resources Group, a Brazilian startup company that can supply Tesla with lithium, a key ingredient of electric car batteries.

Sigma was granted a license to begin mining lithium by the Environmental Authority of the State of Minas Gerais, the Council of Environmental Policy on June 11, 2019. The license will allow Sigma to mine hard rock lithium, a crucial piece of automotive-grade lithium-ion batteries, for six-years, making the company an extremely valuable asset for automakers pursuing electric mobility.

It should be noted that Brazil was ranked No.7 among countries with the highest concentration of lithium. A large percentage of the metal, used primarily for the production of glass and batteries, is available in the Minas Gerais area.

Sigma has previously met with Tesla’s current lithium supplier, Ganfeng Lithium, a Chinese-based company that is currently the country’s largest supplier of the material. Tesla reportedly organized the meeting between both parties that unfortunately did not end in a deal. Sigma CEO Calvyn Gardner cited the Brazilian startup company could not meet the financial or production needs that Ganfeng requested.

“There’s a bunch of other things that they [Ganfeng] need, not just prices, but other demands which are a little more complicated that sort of restricts Sigma to almost supplying purely into China. It’s not really what we think we should be doing over the long term,” Gardner remarked at a mining conference in Brazil.

Gardner, who calls himself a “fan” of Tesla, was interested in purchasing a Model 3 for himself but ran into roadblocks as Tesla does not have a sales office in the South American country. After import taxes would have more than doubled the cost of the Model 3, he decided to hold off.

Striking a deal with Tesla would directly benefit both companies. Tesla currently uses Gigafactory partner Panasonic as its battery supplier but appears to be seeking to expand it lineup of partners, especially after the Japanese electronics conglomerate has cut its profit outlook due to China’s trade war with the US. Tesla’s acquisition of Maxwell Technologies, an ultracapacitor producer, also hinted at the electric car maker’s plans to pursue battery technology beyond its Panasonic partnership.

It would be beneficial for both Tesla and Sigma to strike a deal directly, with the Brazilian company shipping the lithium to the electric car maker. Unfortunately, this could only happen once makers of cathodes, another primary component of batteries, set up facilities in the United States.

Other large automakers that are bursting into the electric transportation market, such as Volkswagen and BMW, have held talks with Sigma already. Gardner, a graduate of the University of South Africa, is optimistic over the talks with both German automakers. “Having options to get lithium from other jurisdictions and that you can supply over the long term,” he said. “That’s what all of them are interested in and we think Sigma can do that.”

There is no shortage of money or optimism in the lithium mining industry. Sigma has recently received a $30 million loan from Japanese trading group Mitsui, according to Reuters. The money is planned to be used in building Sigma facilities, and will be repaid in a big way: a third of Sigma’s planned output of lithium from its Minas Gerais mining facility.

Tesla China insurance registrations hit Q3 high at 13,400 units

Year-to-date, Tesla’s China registrations are down 6.1% versus 2024 levels.

Tesla’s insurance registrations in China surged to 13,400 units for the week of August 4–10, the highest weekly total so far in the third quarter of 2025. The figure represents a 21.8% increase from the prior week’s 11,000 registrations, as per industry tracking data.

Industry watchers weigh in

Data shared by industry watcher @piloly shows the latest week’s results were 21.8% higher than the previous week, though still down 13.5% year-over-year. After six weeks of Q3 2025, Tesla’s China registrations are tracking 70.9% higher quarter-over-quarter compared to Q2, but remain 11.0% below the same period in Q3 2024. Year-to-date, Tesla’s China registrations are down 6.1% versus 2024 levels.

Tesla China does not release its weekly domestic sales figures, though the company’s overall performance in the country can be inferred through insurance registration data. Fortunately, these registrations are closely tracked by industry watchers as well as automakers such as Li Auto.

More momentum

The August performance so far indicates Tesla may be regaining some momentum after a slower start to the year. Tesla’s sales figures this year have generally lagged behind 2024, thanks in no small part to the company’s changeover to the new Model Y, which was implemented in the United States, China, and Germany.

Tesla China seems to be doing what it can to attract as many customers as possible this quarter. Tesla recently launched a new long-range Model 3 variant in China with a CLTC-rated range of 830 km, as noted in a CNEV Post report. Priced at RMB 269,500 ($37,490), the model is about 14.44% more expensive than the entry-level version and becomes the longest-range Tesla on sale in the market. Tesla is also expected to launch the six-seat Model Y L in China this fall.

Tesla clears the air on Cybertruck ‘deactivation’ video that is obviously fake

Tesla has cleared the air on the viral video, stating it is fake.

Tesla has cleared the air regarding a video that has been circulating, where the owner claims his Cybertruck was “deactivated” by the company while he was driving.

The video was shared on X and showed a driver pulled over on the side of the road, claiming his Cybertruck had been deactivated by Tesla in the middle of traffic. It is very obviously fake to those who know the company, but these kinds of things have a tendency to pick up steam.

The video shows a screen that says:

“Tesla Cybertruck De-Activated. Critical Issue Detected | Contact Customer Service, Comply with Cease & Desist to Re-Activate. Update Failed, Return to Dealer.”

The same person who posted the video also shared an image of what appears to be a Cease and Desist letter from Tesla, but it is also likely fake:

The company finally responded to the video on Monday afternoon, stating that the video is, in fact, fake, reiterating that it will not disable vehicles remotely for any reason.

It is a shame that these types of things happen, especially as people are prone to believe anything they see on the internet. As there is so much misinformation circulating surrounding Tesla and its CEO Elon Musk, it is no surprise that someone would leverage the situation for their own benefit.

If that Cease and Desist letter is not real, perhaps the next one might be. These types of things can truly cause damage to a company’s reputation, and someone getting an idea that Tesla would remotely deactivate a car could prevent them from buying one.

Elon Musk is stepping up for Tesla Service in a big way

Elon Musk is stepping up to help customers in a big way, especially when they are having issues with Tesla’s Service.

Perhaps one of the biggest advantages Tesla owners have is access to Musk through X, his social media platform. Over the years, we’ve seen Tesla add features, refine its cars’ performance, and more, all through asking Musk directly through a post.

Now, Musk is stepping up in another way by resolving a few Service complaints that customers had.

The first occurred last week when a recall on a Tesla battery was not honored by Service. The company sought $30,000 for a replacement and labor, which was not right. Musk responded that he would personally investigate the matter. The vehicle was fixed at no cost as it was a recall, and was ready for pickup the next day.

It also revealed a new strategy Tesla is using to combat service communication issues:

Tesla creates clever solution to simplify and improve its Service

The next occurred with a Cybertruck owner who was in Japan. Their car was parked at an airport in the U.S. and had lost a vast majority of its state of charge, leaving them just fifty miles of range at the time.

Musk reached out to the owner and said Service will take care of the car and will investigate the cause of the battery drain:

There are not too many companies out there where the CEO will get involved with individual issues like these. It’s pretty exclusive to Tesla, as Musk has commonly stepped up to resolve complaints with vehicles or to confront features that some owners might find useful.

Service has been a weak point of the company for some time, but it has worked to refine and resolve customer complaints by building more Service Centers across the world that can handle these issues.
