New details on fatal Tesla crash in Texas revealed in Fire Marshal report
A report from the Harris County Fire Marshal’s Office has provided several new details about the high-profile, fatal Tesla Model S crash that happened earlier this month in Texas. The incident, which triggered a wave of inaccurate reports suggesting that the ill-fated vehicle was “driverless,” has rekindled conversations about Tesla’s response to misinformation and the dangers of irresponsible driving.
Immediately after the crash, Harris County Pct. 4 Constable Mark Herman remarked that reconstructionists who responded to the accident were “100% certain that no one was in the driver seat driving that vehicle at the time of impact.” This triggered reports alleging that Autopilot was somehow involved. Herman also remarked that the blaze that resulted from the crash took about four hours to be extinguished, and that firefighters had to call for Tesla for tips on how to address the ill-fated Model S’ battery fire.
These statements were promptly corrected by CEO Elon Musk, who noted that data logs indicate that Autopilot was not enabled during the incident. Fire Chief of The Woodlands Township Fire Department Palmer Buck also corrected reports about the Model S’ battery fire, noting that the blaze was controlled within two to three minutes. After this, it was no longer an active fire, as the fire department was just focused on keeping the battery as cool as possible. Buck also noted that fire personnel did not call Tesla for help on how to handle the vehicle fire.
According to the recent report from the Harris County Fire Marshal’s Office, the vehicle had sustained a “significant front-end collision” that may have damaged its battery, power distribution system, or battery-temperature control systems. While investigator Chris Johnson noted that he was unable to determine the first heat source of the blaze, he concluded that the fire was caused by the Model S’ collision with the tree. The report also noted that the fire was well underway by the time authorities were on the scene, destroying most parts of the vehicle.
The report provided some details about the ill-fated Model S’ two passengers, both of whom perished in the incident. According to the report, the vehicle’s interior had extensive fire damage when some authorities arrived, and most of the combustible materials in the space had already been destroyed. The crash’s victims, William Varner, 59, and Everette Talbot, 69, were on seats whose frames were already visible due to extensive fire damage.
“Decedent 1 was located in a seated position, a few inches forward of the front right (passenger) seat. Decedent 1’s upper torso was in a forward-leaning position, with both arms forward… Decedent 2 was located in a seated position within the rear left (passenger) seat. Decedent 2’s upper torso was in a rear-leaning position, with both arms rolled back in a pugilistic pose,” the report read.
As noted by Tesla in its Q1 earnings call, the company is currently working directly with local authorities, the NTSB, and the NHTSA, to investigate the incident. Tesla Vice President of Vehicle Engineering Lars Moravy added that so far, an inspection of the ill-fated vehicle revealed that the steering wheel was deformed. This, together with the fact that Autopilot was not activated and that all seatbelts post-crash were unbuckled, hints at the likelihood that someone was in the driver’s seat at the time of the crash.

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.
