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’s Supercharger Diner probably just secured more locations

Published

Tesla’s Supercharger Diner in Los Angeles dominated the company’s global usage rankings after just one year, proving the concept is more than just a one-off novelty location that will fade away.

The performance could incite the company to build more locations, something that CEO Elon Musk has hinted at for some time.

Tesla’s Supercharger Diner delivered 21.2 GWh of energy in its first year of operation, the company’s head of Charging, Max de Zegher, revealed on X. Of the top 10 most utilized Supercharger locations in Tesla’s global infrastructure, the Diner in Los Angeles was the most used by drivers, and it wasn’t particularly close:

On its launch day one year ago, nobody was too sure what the Tesla Diner would be about. It seemed like an interesting concept, and considering it had been in the works for years, it was a highly anticipated launch that many were looking forward to.

Based on its success, we could see additional Diners with Superchargers built throughout the United States, and potentially beyond. Musk has said on several occasions that the company would be willing to bring the Diner idea to more markets.

Of the markets that Musk has mentioned, both Palo Alto and Austin have come to be perceived as ideal selections. However, there are no concrete plans as of now to build new Supercharger Diners anywhere; the location on Santa Monica Boulevard will remain the exclusive spot to pick up Tesla-inspired eats, at least for the time being.

Tesla short sellers win big after shares fall after earnings

Tesla short sellers won big following the company’s massive fall on Wall Street after it reported subpar Earnings on Wednesday.

Tesla short sellers collected about $4.12 billion in single-day profits on Thursday, according to BloombergShares fell as much as 15 percent during Thursday’s session. It closed as one of the worst days for Tesla on Wall Street in the past three years.

Investors sold off the stock after Tesla said it would aggressively direct its spending toward AI and its Optimus robot project. The company had record revenues, which were driven by one of the strongest quarters in terms of vehicle deliveries in company history.

However, it missed EPS estimates by reporting just $0.33, a far cry from the $0.53 analysts expected.

S3 Partners reported that about 3 percent of Tesla’s outstanding stock is sold short. Managing Director at S3, Ihor Dusaniwsky, provided the short seller’s potential profit, as well as another figure: shorts have likely had paper gains of $8.92 billion this year, as Tesla shares are down 30 percent in 2026.

Tesla has burned short sellers many times in the past, but the company’s latest Earnings Call was a chance for those skeptics to taste some payback. Although the company gave some very transparent information regarding future projects, the rollout of Robotaxi, Optimus, and Semi, many investors took their profits on Thursday.

Notable short sellers like Michael Burry have been transparent about their skepticism around Tesla shares. Burry just revealed three weeks ago that he had opened up a new short on the stock, stating he shorted Tesla shares at $416.22. “Happy it jumped back to this level,” he said in a blog post.

At the time of publication, Tesla shares were down about 3 percent and the stock was trading at $309.92.

Tesla door handle saga gets its latest chapter and a big change is coming

Tesla’s long-standing saga regarding its door handles and a manual release has entered its latest chapter, and as a result, a big change is coming.

On Friday, the National Highway Traffic Safety Administration (NHTSA) denied Tesla’s petition that was seeking a defect investigation into roughly 180,000 Model 3 vehicles for an issue involving the emergency mechanical door release.

NHTSA said that Tesla’s petition did not present evidence of a safety-related defect in the door handles or their emergency releases. Instead, the agency determined that it would rather solve the issue of the lack of labeling or location of emergency mechanical door releases and the federal safety rules that govern them.

Essentially, the NHTSA wants to create and enforce rules that would require automakers to make emergency door latch releases more clearly labeled in a car. Despite a Tesla having manual door releases on all four passenger doors, many people do not know they exist or how they work.

Tesla addresses door handle complaints with simple engineering fix

In recent times, Tesla has faced some criticism involving its door handles, specifically because some occupants have reported that they are unable to exit their vehicles after losing power. The door handles on a Tesla are electronically operated, but in the event that the 12V battery dies, there is a manual release that can be used.

The NHTSA only identified a single complaint involving the mechanical door releases: a 2022 Model 3 owner said the release was concealed and unlabeled after the vehicle lost power after a front-end collision. It has also already started to create a separate rulemaking process to make emergency door-egress systems more obvious.

It should be noted that all Teslas have mechanical emergency door releases, but they are placed in various locations as the vehicles have aged and been redesigned from year to year. Refer to the safety manual for your vehicle if you have any confusion about where the emergency releases are and how they work.
