NTSB Prelim Report on fatal Tesla Model X crash: 8-seconds before impact

Published

on

The National Transportation Safety Board has issued a preliminary report on the tragic Tesla Model X crash near Mountain View, CA in March. The NTSB’s preliminary report provided details about the circumstances leading up the accident, as well as observations about the all-electric SUV’s battery pack five days after the crash.

According to the NTSB, preliminary recorded data revealed that the Tesla Model X had its Autopilot engaged with Traffic-Aware Cruise Control set to 75 mph at the time of the accident. The vehicle collided into the crash attenuator, rotating it counterclockwise, removing the front part of the vehicle, and causing subsequent collisions with a 2010 Mazda 3 and a 2017 Audi A4. The NTSB noted that the vehicle’s performance data revealed the following.

  • Autopilot was engaged on four separate occasions during the 32-minute trip. The driver-assist feature was engaged for the last 18 minutes 55 seconds before the collision.
  • During the 18 minute, 55-second period, the Model X provided two visual and one auditory alert advising the driver to place his hands on the car’s steering wheel. The alerts were triggered more than 15 minutes prior to the accident.
  • For the last 6 seconds before the collision, the Model X’s driver did not have his hands on the steering wheel. 
  • At 8 seconds before the crash, the Model X was following a lead vehicle at about 65 mph. At 7 seconds, the Model X began moving left while still following a lead vehicle. At 4 seconds, the Tesla was no longer following a car. At 3 seconds before the accident, the Model X’s speed increased from 62 mph to 70.8 mph. The vehicle’s emergency braking and evasive steering did not engage.
  • During the collision sequence, the Model X’s lithium-ion battery was breached, causing a fire. The flames were extinguished after the Mountain View Fire Department applied about 200 gallons of water and foam during a period of fewer than 10 minutes. In the afternoon, the battery emanated smoke and audible venting was heard, though no flames were observed.
  • On March 28, 5 days after the accident, the Model X’s battery pack reignited. The San Mateo Fire Department extinguished the fire.

The NTSB noted in its preliminary report that it is continuing work with the California Highway Patrol and the California Department of Transportation in investigating the accident. The NTSB stated that all aspects of the crash remain under investigation, and that it intends to issue safety recommendations to prevent similar incidents from taking place.

Tesla and the NTSB initially worked together in investigating the fatal Model X accident. The electric car company and the safety board eventually parted ways, however, due to Tesla’s decision to release crash data before the NTSB’s investigation was complete. Among the information Tesla released was that the driver did not have his hands on the wheel during the final 6 seconds leading up to the accident — information that has been reiterated in the NTSB’s preliminary report. 

According to a Tesla, it opted to withdraw from its party agreement with the NTSB since collaboration with the safety board prevents the public release of safety information until the investigation was finished. People familiar with the matter, however, noted that the NTSB was the one which opted to terminate its collaboration with Tesla, according to a Bloomberg report.

In an update after the accident, Tesla highlighted that the absence of a crash attenuator — a highway safety device designed to absorb the impact of a collision — was already damaged when the Model X collided with the concrete barrier.  In a statement to ABC7 News, Wil Huang, the brother of the ill-fated Model X driver, noted that a working crash attenuator would have saved his brother’s life. Later statements from CalTrans revealed that safety device had been left unrepaired for 11 days before the tragic Model X accident.

Tesla won dual categories in the Euro NCAP Best in Class awards, with the Model 3 being named the safest Large Family Car and the Model Y being recognized as the safest Small SUV.

The feat was highlighted by Tesla Europe & Middle East in a post on its official account on social media platform X.

Model 3 and Model Y lead their respective segments

As per a press release from the Euro NCAP, the organization’s Best in Class designation is based on a weighted assessment of four key areas: Adult Occupant, Child Occupant, Vulnerable Road User, and Safety Assist. Only vehicles that achieved a 5-star Euro NCAP rating and were evaluated with standard safety equipment are eligible for the award.

Euro NCAP noted that the updated Tesla Model 3 performed particularly well in Child Occupant protection, while its Safety Assist score reflected Tesla’s ongoing improvements to driver-assistance systems. The Model Y similarly stood out in Child Occupant protection and Safety Assist, reinforcing Tesla’s dual-category win. 

“The company’s best-selling Model Y proved the gold standard for small SUVs,” Euro NCAP noted.

Euro NCAP leadership shares insights

Euro NCAP Secretary General Dr. Michiel van Ratingen said the organization’s Best in Class awards are designed to help consumers identify the safest vehicles over the past year.

Van Ratingen noted that 2025 was Euro NCAP’s busiest year to date, with more vehicles tested than ever before, amid a growing variety of electric cars and increasingly sophisticated safety systems. While the Mercedes-Benz CLA ultimately earned the title of Best Performer of 2025, he emphasized that Tesla finished only fractionally behind in the overall rankings.

“It was a close-run competition,” van Ratingen said. “Tesla was only fractionally behind, and new entrants like firefly and Leapmotor show how global competition continues to grow, which can only be a good thing for consumers who value safety as much as style, practicality, driving performance, and running costs from their next car.”

Tesla is shifting FSD to a subscription-only model, confirms Elon Musk

Tesla CEO Elon Musk confirmed the upcoming update in a post on social media platform X.

Tesla will be ending one-time purchases of its Full Self-Driving (FSD) system after Valentine’s Day, transitioning the feature to a monthly subscription-only model.

Tesla CEO Elon Musk confirmed the upcoming update in a post on social media platform X.

No more FSD one-time purchases

As per Elon Musk in his post on X, “Tesla will stop selling FSD after Feb 14. FSD will only be available as a monthly subscription thereafter.” This marks a shift in how Tesla monetizes its FSD system, which can now be purchased for a one-time fee or accessed through a monthly subscription. 

FSD’s subscription model has been $99 per month in the United States, while its one-time purchase option is currently priced at $8,000. FSD’s one-time purchase price has swung wildly in recent years, reaching $15,000 in September 2022. At the time, FSD was proficient, but its performance was not on par with v14. This made its $15,000 upfront price a hard sell for consumers.

Tesla’s move to a subscription-only model could then streamline how the company sells FSD. It also lowers the entry price for the system, as even price-conscious drivers would likely be able to justify FSD’s $99 monthly subscription cost during periods when long-distance travel is prevalent, like the holidays.

Musk’s compensation plan and FSD subscription targets

Tesla’s shift to a subscription-only FSD model comes amidst Musk’s 2025 CEO Performance Award, which was approved by Tesla shareholders at the 2025 Annual Shareholders Meeting with roughly 75% support. Under the long-term compensation plan, Musk must achieve a series of ambitious operational milestones, including 10 million active FSD subscriptions, over the next decade for his stock awards to vest.

The 2025 CEO Performance Award’s structure ties Musk’s potential compensation to Tesla’s aggressive targets that span market capitalization, vehicle deliveries, robotics, and software adoption. Apart from his 10-million active FSD subscription target, Musk’s compensation is also tied to Tesla producing 20 million vehicles cumulatively, delivering 1 million Tesla bots, and having 1 million Robotaxis in operation. He must also lead Tesla to a market cap of $8.5 trillion.

If successful, Elon Musk’s 2025 CEO Performance Award could make him the world’s first trillionaire. It could also help Tesla become the world’s most valuable company by market cap by a notable margin.

Tesla plans for new 300+ stall Supercharger with a special surprise for Semi

Tesla is planning for a new 300+ stall Supercharger station that will be an expansion of an existing facility, and the company is planning to add a surprise for the Semi.

The Firebaugh, California Supercharger is currently 72 Superchargers, but Tesla filed for an expansion that will add 232 additional plugs for passenger vehicles, and it also plans to add 16 Semichargers.

This will be the biggest Supercharger station Tesla will have to date, just months after it finished the Supercharger Oasis in Lost Hills, California, which has 168 stalls. This will have 304 total Supercharger stalls, and then the additional 16 Megachargers.

The Firebaugh Supercharger is located on I-5, which is a major reason for why Tesla has chosen the location for additional Megacharger plug-ins, as Tesla Semi Program Manager Dan Priestley said on X earlier today.

The project was revealed by MarcoRP, a Supercharger tracker.

The expansion is a massive signal for charging demand, especially as Tesla’s Superchargers are opened to numerous automakers and are no longer exclusive to the company’s EVs. Additionally, the installation of Megachargers is a good sign to come for the Tesla Semi program, which aims to truly ramp up this year.

Tesla plans to launch production of the Semi later this year.

It could also mean Tesla is going to expand its footprint of large-scale Supercharger projects in the coming years, which would be a big boost as EV adoption continues to soar in the United States.
