Tesla sued by female engineer over allegations of “pervasive harassment”
Tesla has been sued by a female engineer who alleges that a climate of “pervasive harassment” has impeded her career advancement. This lawsuit is one more in a series of recent accusations by females against Silicon Valley technology companies.
Update: Tesla issues an official response to the lawsuit
AJ Vandermeyden, 33, whose career at Tesla began in 2013 and continues today, has come forward at a time when nondisclosure statements prohibit most internal accounting of technology sector working conditions. Among Vandermeyden’s claims are a lower salary than males at comparable job assignments, promotions based on gender rather than qualifications, and a cultural climate where a female who raises concerns becomes the object of internal human resources scrutiny.
Her complaints include male co-workers engaging in sexual harassment that goes unaddressed by human resources. Vandermeyden insists she is dedicated to Tesla, which is part of her motivation for coming forward to advocate for fair treatment and reforms. The engineer owns a Tesla Model S and has a reservation for the upcoming Tesla Model 3. “Until somebody stands up, nothing is going to change,” she said in a recent interview to The Guardian about the discrimination lawsuit she filed last year. “I’m an advocate of Tesla. I really do believe they are doing great things. That said, I can’t turn a blind eye if there’s something fundamentally wrong going on.” She acknowledges that she may face serious risks for making the public aware of her lawsuit against Tesla.

Vandermeyden’s lawyer, Therese Lawless, states that many females in similar positions choose not to speak up. “It’s very difficult for women to come forward. They’re concerned that their career is going to be hindered or jeopardized.”
Vendermeyden moved up through the Tesla ranks to a manufacturing engineering position in the general assembly department, where she was paid less than the male engineers whose position and responsibilities she had assumed. This structure of strong relative percentages wages of males to females is typical throughout the Tesla organization, where its highest paid and most prestigious positions are held by males, with only two out of thirty vice-presidents self-describing as female. In Vandermeyden’s case, it was common for her to be the only female in meetings with forty to fifty males.
She outlined how this male-centric Tesla workplace can be hostile to women and dismissive when discussions around barriers to female workplace equality are raised. The response, she says, is often: “‘We’re focused on making cars. We don’t have time to deal with all this other stuff.’”
The complaint, which was filed in autumn, 2016, alleges that, although Vandermeyden designed a solution to compensate for inadequacies in vehicle quality testing which had been overlooked by supervisors and male engineers, she was not recognized for her problem-solving at the time of performance reviews. Instead, her lawsuit claims that Tesla retaliated against her for being a “whistleblower” when she raised concerns about these cars “sold in a defective state.” The result? Males were granted positions above her, according to the complaint, which her lawyers indicate is a pattern in which she and other female engineers were denied promotions even though they were “equally or more qualified” than the males. The lawsuit outlines how Tesla denied her overtime pay, rest breaks, and meal periods when she worked in sales, as well.
She also experienced “unwelcome and pervasive harassment by men on the factory floor including but not limited to inappropriate language, whistling, and cat calls,” the lawsuit says. Objections about sexual harassment, which she raised in 2015, went unheeded. Instead, Vandermeyden was told that, in order to advance her position, she must achieve what she felt was an unattainable factory performance standard, one that was not expected of male engineers. Despite the positive performance evaluations she received, Vandermeyden concluded that her best opportunities for career advancement and overcoming institutional barriers were to transfer to the purchasing department, her current position at Tesla, Inc.
Tesla is not alone in its alleged imbalanced gender culture. Tensions at Uber emerged last week when former engineer Susan Fowler wrote a blog post in which she chronicled a year of work at Uber. In that narrative, she described a chaotic internal culture, a human resources department that made excuses for sexual harassment, frequent episodes where victims were blamed, and a pattern of promotions based on insider preference rather than data-driven performance. Uber CEO Travis Kalanick this week addressed a group of 100+ Uber female engineers to listen to their concerns. Kalanick offered some concessions during his meeting with the female engineers. “So I empathize with you, but I can never fully understand, and I get that. I want to root out the injustice. I want to get at the people who are making this place a bad place. And you have my commitment to make that happen.”
Vandermeyden says, “It’s shocking in this day and age that this is still a fight we have to have.” Her statement acknowledges that any company with more than 30,000 employees will necessarily have a small number of individuals who make claims against the company. Yet, “that does not mean those claims have merit,” the statement adds. “Equal pay is something that is essentially in the back of your mind every single day. You have all these data points showing how you’ve exceeded some of the predecessors and improved on the system. It wears on you.”
Tesla CEO Elon Musk found himself embroiled in another employment controversy earlier this month in which an employee complained of unfair working conditions and discussed how other workers have approached the UAW about possible unionization. Musk used Twitter to wonder aloud whether that complainant was fact or fake news, a Tesla employee or a UAW shill.
Vandermeyden admits she wonders about her future at Tesla. “Half the time when I walk into work, I wonder if my badge is going to work.”

Tesla Cybercab spotted with interesting charging solution, stimulating discussion
The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Tesla Cybercab units are being tested publicly on roads throughout various areas of the United States, and a recent sighting of the vehicle’s charging port has certainly stimulated some discussions throughout the community.
The Cybercab is geared toward being a fully-autonomous vehicle, void of a steering wheel or pedals, only operating with the use of the Full Self-Driving suite. Everything from the driving itself to the charging to the cleaning is intended to be operated autonomously.
But a recent sighting of the vehicle has incited some speculation as to whether the vehicle might have some manual features, which would make sense, but let’s take a look:
🚨 Tesla Cybercab charging port is in the rear of the vehicle!
Here’s a great look at plugging it in!!

The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Now, it is important to remember these are prototype vehicles, and not the final product. Additionally, Tesla has said it plans to introduce wireless induction charging in the future, but it is not currently available, so these units need to have some ability to charge.
However, there are some arguments for a charging system like this, especially as the operation of the Cybercab begins after production starts, which is scheduled for April.
Wireless for Operation, Wired for Downtime
It seems ideal to use induction charging when the Cybercab is in operation. As it is for most Tesla owners taking roadtrips, Supercharging stops are only a few minutes long for the most part.
The Cybercab would benefit from more frequent Supercharging stops in between rides while it is operating a ride-sharing program.

However, when the vehicle rolls back to its hub for cleaning and maintenance, standard charging, where it is plugged into a charger of some kind, seems more ideal.
In the 45-minutes that the car is being cleaned and is having maintenance, it could be fully charged and ready for another full shift of rides, grabbing a few miles of range with induction charging when it’s out and about.
Induction Charging Challenges
Induction charging is still something that presents many challenges for companies that use it for anything, including things as trivial as charging cell phones.
While it is convenient, a lot of the charge is lost during heat transfer, which is something that is common with wireless charging solutions. Even in Teslas, the wireless charging mat present in its vehicles has been a common complaint among owners, so much so that the company recently included a feature to turn them off.
Production Timing and Potential Challenges
With Tesla planning to begin Cybercab production in April, the real challenge with the induction charging is whether the company can develop an effective wireless apparatus in that short time frame.
It has been in development for several years, but solving the issue with heat and energy loss is something that is not an easy task.
In the short-term, Tesla could utilize this port for normal Supercharging operation on the Cybercab. Eventually, it could be phased out as induction charging proves to be a more effective and convenient option.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.
