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.

A new report from Reuters claims that a transport authority in Sweden is pushing back against the approval of Tesla’s Full Self-Driving suite because it will travel over speed limits.
The report says the Swedish Transport Administration (TRV) recommends the European Union votes against FSD’s approval. TRV believes it should not be approved until Tesla disables FSD’s ability to speed.
TRV sent a letter to the European Union’s Technical Committee on Motor Vehicles (TCMV), which is set to meet on June 30 to discuss the potential approval of the Tesla FSD suite in the country. Tesla, which has received various approvals in Europe over the past two months, has not provided a comment.
Teslas operating on FSD do travel over the speed limit, depending on the Speed Profile that is chosen. Drivers have the ability to disengage FSD at any point; Tesla specifically states that those supervising the suite are responsible for its actions.
Let’s cut to the chase: humans operating any vehicle speed almost daily in the United States. Realistically, speed limits in the U.S. are more frequently treated as speed minimums. However, other countries are different, and driving behaviors are less aggressive.
TRV believes that “allowing automated systems to systematically exceed legal speed limits…risks undermining both the legal framework and the expected safety benefits of vehicle automation,” the report stated. It’s surprising that Tesla has not received this claim from other countries previously.
This could be a good argument to bring Max Speed back, the setting that previously allowed the driver to choose the absolute fastest the car would travel.
This would still put the responsibility of supervision in the hands of the driver. It would allow the driver to choose whether the car would travel over the speed limit or not, acknowledging that they set the speed, and if they get pulled over, there would be no ability to argue it.
However, it does not seem as if this is something Tesla will do, especially considering many U.S. drivers have requested the feature in an effort to eliminate speeding or at least tone it down. The company has not shown any interest in bringing it back.
Tesla has approvals for FSD in Europe in Estonia, Lithuania, Denmark, the Netherlands, and Belgium.
Tesla is going to let you guide Full Self-Driving with Grok in 3 months, CEO Elon Musk confirmed on X.
The response from Musk, which revealed Tesla plans to allow drivers to effectively control the car and its navigation more explicitly using Grok, puts the feature for about September.
A Tesla owner said that Full Self-Driving is great, but owners should be able to “converse with Grok like we can with an Uber driver.” She then used examples like, “Grok, turn right here,” and “Drop us off right here, we’ll walk due to traffic,” and finally,” Drop at entrance first, then park far away.”
Coincidentally, the final piece of dialogue would also mean features like Banish are potentially on the way soon.
This functionality will be there in about 3 months or so
— Elon Musk (@elonmusk) June 18, 2026
Banish is also referred to as “Reverse Summon,” and would enable the car to self-park while dropping occupants off at their destination.
This would be a great way to improve the overall experience while supervising FSD. Navigation is already a major painpoint that many owners complain about. Manual overrides when a maneuver is requested or canceled (like using the turn signal stalk to override a navigation route), do not always work.
The feature could be especially useful in street parking scenarios in a city, where spots are sometimes tough to come by. Many of us who grab dinner in a more populated area will park a street or two over from wherever we’re going, because sometimes you know that’s the best you will get. If a driver using FSD could say, “Hey Grok, turn right here on Queen St. and park in that open spot on the right,” it could save a lot of confusion FSD might have on its own.
Musk teased that a similar feature was “coming” back in February:
Tesla Full Self-Driving set to get an awesome new feature, Elon Musk says
It is certainly surprising that Tesla is doing it at this point. The company’s more recent moves have been more evident of taking control and inputs away from humans and putting them in the AI’s hands more frequently. The biggest example of this was taking away Max Speed in AI4 cars, giving us Speed Profiles, and not having any input on the fastest speed the car will travel.
Of course, giving navigation preferences to Grok is availble already in Teslas, but not at the drop of a hat. Instead, you can suggest a certain route at the beginning of your drive.
Here’s an example of that from December:
🚨🏈 I am taking my parents and Fiancee to the @Ravens game next weekend and asked @Grok to help me route my @Tesla through a specific neighborhood to reach the correct Lot we will park in.
This is a great example of the new @grok nav integration with the Tesla Holiday Update: pic.twitter.com/rPp4I7q8Yv

Finally, the original post that Musk responded to mentioned a parking preference after dropping off the occupants, which describes the Banish feature that Tesla has teased for years.
We’re not sure if Musk was responding more to the ability to guide the car with Grok, or whether he also was including Banish in the three-month prediction timeframe.
A close-up image of a Cybercab engineering vehicle in Peabody, Massachusetts, reveals a compact triangular side repeater camera housing equipped with an integrated washer mechanism.
This seemingly small hardware addition could prove to be one of the most critical components for achieving reliable, unsupervised Full Self-Driving (FSD) — not just for the dedicated Robotaxi but potentially for existing AI4-equipped vehicles as well.
The washer system’s importance cannot be overstated in Tesla’s vision-only autonomy approach. Cameras are the sole sensory input for the neural networks powering FSD, constantly interpreting the environment for safe navigation. In real-world conditions, however, lenses quickly accumulate rain, snow, mud, dust, or road spray.
Many of us Tesla owners, especially those who deal with any sort of winter weather at all, know the all-too-common alert that pops up when cameras are obstructed:
Even brief obstructions can drop perception confidence, trigger safety disengagements, or force the vehicle to pull over, although these are relatively rare. Instead, most of the time, the camera will need a wipe from the owner next time they stop the car.
But unlike human drivers who can manually clear their view, a Robotaxi operating 24/7 without a steering wheel or mirrors must maintain pristine vision autonomously. The Cybercab’s side repeater washer delivers targeted cleaning bursts precisely where needed for merging, lane changes, and blind-spot monitoring — functions that demand uninterrupted visibility from the external cameras:

This hardware directly tackles a known pain point in current FSD deployments. Owners frequently report camera-related alerts during inclement weather, which is understandable, but needs to be solved for a true autonomous experience.
For a production Robotaxi fleet aiming for high utilization and minimal downtime, robust washer systems represent a foundational reliability upgrade; essentially, they’re a must-have. Early sightings suggest the design may extend to rear cameras as well, creating a comprehensive cleaning architecture that keeps the entire vision suite operational in harsh environments.
Without it, even the most advanced neural nets struggle when their “eyes” are compromised.
What Does This Mean for AI4 Cars?
This Cybercab detail raises timely questions for AI4 cars already on the road. While Hardware 4 delivers superior compute and camera resolution compared to earlier versions, production models typically lack dedicated side and rear washers. Tesla has included them on Model Y robotaxis that it is using in the fleet:
Tesla Robotaxi has a highly-requested hardware feature not available on typical Model Ys
As Tesla refines unsupervised FSD for broader release, the gap in environmental resilience becomes evident. Software improvements can help mitigate issues, but they cannot fully replace physical cleaning in heavy rain or muddy conditions. Analysts and owners increasingly speculate that AI4 vehicles may eventually require similar washer retrofits — or a future AI4.5 variant — to match the Cybercab’s all-weather readiness and support the same level of autonomy.
As testing progresses, the Cybercab’s washer mechanism highlights Tesla’s pragmatic focus on real-world robustness. It may well become the hardware piece that determines how quickly and reliably FSD scales from prototypes to everyday vehicles.
