By Investing.com — Tesla shares are down around 0.6% premarket Friday after it was revealed that the National Highway Traffic Safety Administration (NHTSA) has opened an investigation into 2.4 million Tesla (NASDAQ:TSLA) vehicles.
The investigation follows an incident where a vehicle equipped with Full Self-Driving (FSD) technology struck a pedestrian.
The U.S. auto safety regulator’s Office of Defects Investigation (ODI) reported four instances of Tesla vehicles crashing in reduced visibility conditions with FSD engaged.
The ODI has begun a preliminary evaluation of Tesla’s FSD. It will now assess the technology’s capacity to detect and respond appropriately to decreased roadway visibility conditions.
Furthermore, it will look at any updates or modifications from Tesla to the FSD system that could impact its performance in reduced roadway visibility conditions.
Tesla shares are trading at around $219.60 level in premarket trading. The stock is down over 11% this year and more than 8% in the last week.
On Thursday, Tesla released a video showing its Optimus robot prototypes are making in moving independently. The clip, which lasts just under 90 seconds, was posted on Elon Musk’s X platform (formerly Twitter).
In the video, Tesla’s Optimus is shown walking around a factory floor. The company says the robot can now “explore unseen spaces autonomously.”
