The escalated probe by the United States — National Highway Traffic Safety Administration into Tesla, Inc.'s Full Self-Driving system, covering 3.2 million vehicles, is likely to negatively impact Tesla, Inc.'s stock price and its ambitious plans for robotaxis. The potential for a recall and the ongoing regulatory scrutiny could erode investor confidence and delay the widespread adoption of its self-driving technology.
The United States — National Highway Traffic Safety Administration has escalated its probe into 3.2 million Tesla, Inc. vehicles equipped with the Full Self-Driving (FSD) driver-assistance system. The agency is concerned that Tesla, Inc.'s camera-based system may fail to detect or warn drivers in poor visibility conditions, such as glare or dust, and has opened an engineering analysis, a precursor to a potential recall. The investigation follows reports of nine incidents, including one fatal crash and two injury crashes, that may be linked to the FSD system's performance. The United States — National Highway Traffic Safety Administration noted that when Tesla, Inc. transitioned to an exclusively camera-based approach (Tesla, Inc. Vision) in mid-2021, the degradation detection system implemented may not be adequately warning drivers. This increased regulatory scrutiny adds pressure to Tesla, Inc.'s long-term strategy of developing a fleet of robotaxis, especially as the company seeks FSD approvals in markets like China and Europe.
