Tesla says ‘brake failure’ protestor vandalized Model 3, refused third-party testing
Tesla is navigating through a difficult bout with an owner in Shanghai, China, named Zhang Yazhou, who appeared at the Shanghai Auto Show last week in protest of what she claimed was a faulty Model 3 braking system. Tesla has now issued a more lengthy and detailed description of their encounters with Mrs. Zhang, revealing that she not only vandalized her own car with red spray paint, but she also denied any requests made by Tesla to have an independent, third-party company investigate whether the Model 3 had braking issues.
On April 19th, Zhang climbed on top of a Model 3 that was positioned at the Tesla booth at the Shanghai Auto Show. Wearing a shirt that said “Tesla Brake Failure,” Zhang yelled “Tesla brakes failed me” to a crowd of spectators who surrounded the all-electric sedan. As a result, Tesla has released several responses, including data from the accident that showed the driver, who was actually Zhang’s father, was driving at a speed that was above the posted speed limit and engaged the braking system successfully on more than 40 occasions in the half-hour leading up to the accident.
Now, Tesla is making more attempts to reveal the story to the public and is revealing its interactions with Zhang.

On Tesla’s official Weibo page, the company stated that Zhang talked to Tesla on April 27th, and the automaker was willing to continue communicating and try to come to a solution. After a five-day stint with the Police following the protest, Zhang returned home and told Tesla reps, “I just came back. I need to adjust. I hope you can show an attitude that really solves the problem. When you have this attitude, we will communicate.”
Tesla revealed that Zhang was in the passenger’s seat during the accident and that traffic police came to the conclusion that the driver, Zhang’s father, was “fully responsible for the accident because he did not maintain a safe distance from the vehicle in front.” After the vehicle arrived at a local service shop for repairs on February 22, Tesla says Ms. Zhang put a seal on the vehicle three days after its arrival so nobody could enter the car. Tesla says that Zhang believed the vehicle’s data could be tampered with, and this was the reason for the seal being placed on the doors. Zhang had the still-wrecked vehicle towed to Tesla’s Zhengzhou Fotamen showroom on March 5th, where it would be sitting in the public for everyone to see.

The following day, Zhang placed a banner that read “Brake Failure” on the car, and Tesla began offering Zhang the option of having third-party inspectors take a look at the car on their dime. Zhang refused, saying that she was not interested in having the car looked at by “non-accredited third-party testing agencies,” and warned that Tesla should “look for pressure from the media” if the car wasn’t returned.

Zhang then came back to the showroom where her car was located and spraypainted the exterior of her wrecked Model 3 with red paint. The words once again said, “Brake Failure.”
“The Tesla staff are still actively communicating with Ms. Zhang, trying to find a solution, and negotiating with her husband, Mr. Li, hoping to minimize the impact and help her maximize the benefits within a reasonable range. Mr. Li made it clear that he still has a “team” from Beijing assisting him, and being helped by others in “cooperating” with others can only be obedient,” Tesla added. Zhang resealed her vehicle on March 21st.

According to Tesla, Zhang then had the car towed to the Zhengzhou Dahe Auto Show, where two hired models stood beside the car. Zhang then made her appearance at the Shanghai Auto Show on April 19th. Tesla says that it is still working to iron out the situation and work with Zhang and her husband, who is identified as Mr. Li. Tesla sent a sealed version of the vehicle data that was available 30 minutes before the accident occurred to Zhang’s house.
“Since February, we have been doing our best to actively communicate with Ms. Zhang and her family. We sincerely hope that we can promote vehicle inspection as soon as possible and give a result to the friends who care about Tesla,” the company concluded.

Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry
Tesla set to launch “Terafab Project: A vertically integrated chip fabrication effort combining logic processing, memory, and advanced packaging.
Tesla is making one of the boldest bets in its history. On March 14, Elon Musk posted on X that the “Terafab Project launches in 7 days,” pointing to March 21, 2026 as the start date for what he has described as a vertically integrated chip fabrication effort combining logic processing, memory, and advanced packaging.
Tesla first confirmed Terafab on its January 28, 2026 earnings call, where Musk told investors the company needs to build a chip fabrication facility to avoid a supply constraint projected to materialize within three to four years. But the seeds were planted even earlier. At Tesla’s annual general meeting last year, Musk warned that even in the best-case scenario for chip production from their suppliers, it still wouldn’t be enough, and declared that building a “gigantic chip fab” simply had to be done.
While there has been no official announcement on where Tesla plans to break ground on the massive Terafab, all signs point to the North Campus of Giga Texas in Austin.
Months of speculation has surrounded Tesla’s North Campus expansion at Giga Texas, where drone footage captured by observer Joe Tegtmeyer revealed massive construction site preparation just north of the existing factory on a scale that rivals the original Giga Texas footprint itself.
Samsung’s Tesla AI5/AI6 chip factory to start key equipment tests in March: report
The project is projected to produce 100–200 billion AI and memory chips annually, targeting 100,000 wafer starts per month, at an estimated cost of $20 billion. Tesla is targeting 2-nanometre process technology and anticipated to be the most advanced node currently in commercial production. Dubbed the Tesla AI5 chip, the chip will pack 40x–50x more compute performance and 9x more memory than AI4, and will be among the first products Terafab factory is set to produce. This highly optimized, and massively powerful inference chip is designed to make full self-driving (FSD) and Tesla’s Optimus robots faster, safer, and with full autonomy.

This is where Terafab becomes a genuine game-changer. If Tesla successfully builds a 2nm chip fab at scale, it becomes one of only a handful of entities that’s capable of producing AI silicon in-house, with competitive implications that extend far beyond Tesla’s own vehicles, and potentially positioning Tesla as a chip supplier or licensor to other industries.

The next-gen Tesla AI chips will power advancements in Full Self-Driving software, the Cybercab Robotaxi program, and the Optimus humanoid robot line. Musk’s projections for Optimus require chip volumes that no existing external supplier can commit to on Tesla’s timeline.Competitors like Waymo and GM’s Cruise remain dependent on third-party silicon, leaving them exposed to the same supply chain vulnerabilities Tesla is now working to eliminate entirely.
The Terafab launch this week may not mean a factory opens its doors overnight, but it signals Tesla is serious about owning the entire AI stack, from software to silicon.

What is Digital Optimus? The new Tesla and xAI project explained
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Tesla and xAI announced their groundbreaking joint project, Digital Optimus, also nicknamed “Macrohard” in a humorous jab at Microsoft, earlier this week.
This software-based AI agent is designed to automate complex office workflows by observing and replicating human interactions with computers. As the first major outcome of Tesla’s $2 billion investment in xAI, it represents a powerful fusion of hardware efficiency and advanced reasoning.
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Macrohard or Digital Optimus is a joint xAI-Tesla project, coming as part of Tesla’s investment agreement with xAI.
Grok is the master conductor/navigator with deep understanding of the world to direct digital Optimus, which is processing and actioning the past 5 secs of…
— Elon Musk (@elonmusk) March 11, 2026
Tesla’s specialized AI acts as “System 1”—the fast, instinctive executor—processing the past five seconds of real-time computer screen video along with keyboard and mouse actions to perform immediate tasks.
xAI’s Grok model serves as “System 2,” the strategic “master conductor” or navigator, providing high-level reasoning, world understanding, and directional oversight, much like an advanced turn-by-turn navigation system.
When combined, the two can create a powerful AI-based assistant that can complete everything from accounting work to HR tasks.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
The system runs primarily on Tesla’s low-cost AI4 inference chip, minimizing expensive Nvidia resources from xAI for competitive, real-time performance.
Elon Musk described it as “the only real-time smart AI system” capable, in principle, of emulating the functions of entire companies, handling everything from accounting and HR to repetitive digital operations.
Timelines point to swift deployment. Announced just days ago, Musk expects Digital Optimus to be ready for user experience within about six months, targeting rollout around September 2026.
It will integrate into all AI4-equipped Tesla vehicles, enabling parked cars to handle office work during downtime. Millions of dedicated units are also planned for deployment at Supercharger stations, tapping into roughly 7 gigawatts of available power.
Oh and it works in all AI4-equipped cars, so your car can do office work for you when not driving.
We’re also deploying millions of dedicated Digital Optimus units in the field at Superchargers where we have ~7 gigawatts of available power.
— Elon Musk (@elonmusk) March 12, 2026
Digital Optimus directly supports Tesla’s broader autonomy strategy. It leverages the same end-to-end neural networks, computer vision, and real-time decision-making tech that power Full Self-Driving (FSD) software and the physical Optimus humanoid robot.
By repurposing idle vehicle compute and extending AI4 hardware beyond driving, the project scales Tesla’s autonomy ecosystem from roads to digital workspaces.
As a virtual counterpart to physical Optimus, it divides labor: software agents manage screen-based tasks while humanoid robots tackle physical ones, accelerating Tesla’s vision of general-purpose AI for productivity, Robotaxi fleets, and beyond.
In essence, Digital Optimus bridges Tesla’s vehicle and robotics autonomy with enterprise-scale AI, promising massive efficiency gains. No other company currently matches its real-time capabilities on such accessible hardware.
It really could be one of the most crucial developments Tesla and xAI begin to integrate, as it could revolutionize how people work and travel.

Interestingly, we’re not too sure what catalyzed Tesla to try to improve braking smoothness, because it hasn’t seemed overly abrupt or rough from my perspective. Although the brake pedal in my Model Y is rarely used due to Regenerative Braking, it seems Tesla wanted to try to make the ride comfort even smoother for owners.
There is always room for improvement, though, and it seems that there is a way to make braking smoother for passengers while the vehicle is coming to a stop.
This is far from the first time Tesla has attempted to improve its ride comfort through Over-the-Air updates, as it has rolled out updates to improve regenerative braking performance, handling while using Full Self-Driving, improvements to Steer-by-Wire to Cybertruck, and even recent releases that have combatted Active Road Noise.
Tesla holds a unique ability to change the functionality of its vehicles through software updates, which have come in handy for many things, including remedying certain recalls and shipping new features to the Full Self-Driving suite.
Tesla seems to have the most seamless OTA processes, as many automakers have the ability to ship improvements through a simple software update.
We’re really excited to test the update, so when we get an opportunity to try out Comfort Braking when it makes it to our Model Y.
