Chinese Find Obvious Tesla Model S Security Flaw
A group of Chinese hacker reported that the Model S has a security flaw. We say, welcome to reality. Any system that is connected, whether physical or wireless, has a potential security flaw.
Model S has a security flaw
The Tesla Model S security flaw is making its round lately. It has to make you wonder when reports on security exploits related to computer systems appear. Modern computers, including cars and their wireless technologies have many open ports and channels. A long, long time ago, when I was learning about Novell servers, (yes, I’m that old) my teacher taught me that a truly un-hackable computer is one without a mouse, keyboard or Internet connection. It helped to understand that once a port is open, either with a keyboard of wireless connection, even if secured, there is still a potential vulnerability.
The Model S open connections mean potential security flaw
The Model S is not really a car. It’s more of a future template of what every car will soon look like. It is more of a rolling computer on wheels, which handles quite well. But the Tesla Model S is always connected, either to Tesla Motors, or the Internet, as well as many other types communication is happening. What this means is that the Model S is, by definition, as vulnerable as its weakest point in the security chain. So is it any wonder to hear that the Model S, the most Internet-connected and remotely-connected electric vehicle (EV) on the market today, has a major security flaw? It shouldn’t. Anything connected cars, even Tesla’s Model S means it can be hacked and has security flaws.
According to TransportEvolved, Sina Weibo announced a Chinese Internet security company called Qihoo 360, found Tesla Model S security flaw. This is one of the most common security issue with anything connected and it means a crafty hacker can remotely access and unlock your Tesla Model S, as well as sound the horns, use the headlights, wipers, and even the panoramic sunroof. Are you scared yet? At the very least, if it rains, you might get annoyed.
Making sense of the Tesla Model S security flaw
Once we take a few steps back, we can see a pattern emerging from this Tesla Model S security flaw news. First, it was announced a day before one of the biggest security conference in China, the 2014 SyScan +360. Add to this that the conference is awarding a $10,000 prize to whoever successfully hacks into a Tesla Model S, and you get a better picture of what is happening. The Tesla Motors Model S is as secured as can be, and will continue to be more secured as each individual security flaws are discovered.
Tesla Motors was quick to reassure us with the following: “While Tesla is not associated with the conference and is not a sponsor of the competition, we support the idea of providing an environment in which responsible security researchers can help identify potential vulnerabilities. We hope that the security researchers will act responsibly and in good faith.” Whether open or closed sources, nothing is 100% secured if it is connected.
But joking apart, news of the Tesla Model S security flaw is a welcome relief in a world of over-confidence and side-blinders. In the meantime, as user and hacker feedback rolls in, Tesla will rewrite some APIs and take a closer look at some of the certificates it uses. So far, if sounding your horn, opening your doors and sunroof are the biggest threats, we can say that the latest Tesla Motors Model S security flaw is only a potential… so far.
The Tesla Model X has always been one of the company’s most loved vehicles, despite its low sales figures, which can be attributed to its high price tag.
However, the Model X has been a signature item on Tesla’s menu of cars, most notably recognized by its Falcon Wing Doors, which are aware of its surroundings and open according to what’s around it.
But recent improvements to the Model X were looking slim to none, but it appears most of the fixes actually happened under the body, at least according to Tesla’s Vice President of Powertrain, Lars Moravy.
In a recent interview with Car and Driver, Moravy detailed all of the changes to the 2026 iteration of the vehicle, which was about 400 pounds lighter than it was originally. The biggest change is a modification with the rear motor, switching from an induction-type motor to a permanent-magnet design and optimizing the half-shafts, which shed about 100 pounds.
Tesla also got “almost 80 pounds out of the interior bits and pieces,” which “included making parts thinner, different manufacturing process choices, and incorporating airbag-deployment requirements into the headliner fabric,” the report said.
Additionally, the standard five-passenger, bench seat configuration saved 50 pounds by ditching pedestal mounting. This also helped with practicality, as it helped the seat fold flat. Engineers at Tesla also saved 44 pounds from the high-voltage wiring through optimizing the wiring from the charge-port DC/DC converter and switching from copper to aluminum wiring.

Tesla also simplified the cooling system by reducing the number of radiators. It also incorporated Nürburgring cooling requirements for the Plaid variant, which saved nearly 30 pounds.
Many Tesla fans will be familiar with the megacastings, manufactured in-house by presses from IDRA, which also saves more than 20 pounds and boosts torsional stiffness by around 10 percent. Tweaks to the suspension also saved 10 pounds.
People were truly disappointed with what Tesla did with the Model S and Model X, arguing that the cars needed a more severe exterior overhaul, which might be true. However, Tesla really did a lot to reduce the weight of the vehicle, which helps increase range and efficiency. According to Grok, every 200 pounds removed adds between 7 and 15 percent to range estimations.
This makes sense considering the range estimations both increased by 7 percent from the Model X’s 2025 configuration to the 2026 builds. Range increased on the All-Wheel-Drive trim from 329 miles to 352 miles, while the Plaid went from 314 miles to 335 miles.
Tesla has officially launched its first branded Supercharger just months after initiating a new program that allows third-party companies to brand their own charging piles.
The site opened in Land O’ Lakes, Florida, and features eight V4 Supercharging stalls offering up to 325 kW of charging speed. It appears it was purchased by a company called Suncoast Credit Union. This particular branch is located Northeast of Tampa, which is on the Gulf of Mexico.
It features graphics of Florida animals, like alligators:

Tesla launched this program back in September, and it basically was a way to expand its Supercharger presence and also allow companies to pay for the infrastructure. Tesla maintains it. When it announced the “Supercharger for Business,” it said:
“Purchase and install Superchargers at your business. Superchargers are compatible with all electric vehicles, bringing EV drivers to your business by offering convenient, reliable charging.”
The program does a few things. Initially, it expands EV charging infrastructure and makes charging solutions more readily available for drivers. It can also attract people to those businesses specifically.

The chargers can also be branded with any logo that the business chooses, which makes them more personalized and also acts as an advertisement.
The best part is that the customers do not have to maintain anything about the Supercharger. Tesla still takes care of it and resolves any issues:
“We treat your site like we treat our sites. By providing you with a full-service package that includes network operations, preventative maintenance, and driver support, we’re able to guarantee 97% uptime–the highest in the industry.”
It appears the Superchargers will also appear within the in-car nav during routing, so they’ll be publicly available to anyone who needs to use them. They are still available to all EVs that have worked with Tesla to utilize its infrastructure, and they are not restricted to people who are only visiting the business.
Tesla has revealed its Cybertruck light bar installation fix after a recall exposed a serious issue with the accessory.
Tesla and the National Highway Traffic Safety Administration (NHTSA) initiated a recall of 6,197 Cybertrucks back in October to resolve an issue with the Cybertruck light bar accessory. It was an issue with the adhesive that was provided by a Romanian company called Hella Romania S.R.L.
Tesla recalls 6,197 Cybertrucks for light bar adhesive issue
The issue was with the primer quality, as the recall report from the NHTSA had stated the light bar had “inadvertently attached to the windshield using the incorrect surface primer.”
Instead of trying to adhere the light bar to the Cybertruck with an adhesive, Tesla is now going to attach it with a bracketing system, which will physically mount it to the vehicle instead of relying on adhesive strips or glue.
Tesla outlines this in its new Service Bulletin, labeled SB-25-90-001, (spotted by Not a Tesla App) where it shows the light bar will be remounted more securely:
The entire process will take a few hours, but it can be completed by the Mobile Service techs, so if you have a Cybertruck that needs a light bar adjustment, it can be done without taking the vehicle to the Service Center for repair.
However, the repair will only happen if there is no delamination or damage present; then Tesla could “retrofit the service-installed optional off-road light bar accessory with a positive mechanical attachment.”
The company said it would repair the light bar at no charge to customers. The light bar issue was one that did not result in any accidents or injuries, according to the NHTSA’s report.
This was the third recall on Cybertruck this year, as one was highlighted in March for exterior trim panels detaching during operation. Another had to do with front parking lights being too bright, which was fixed with an Over-the-Air update last month.
